Answer:

Asteroids and comets have a few things in common. They are both celestial bodies orbiting our Sun, and they both can have unusual orbits, sometimes straying close to Earth or the other planets. They are both “leftovers” — made from materials from the formation of our Solar System 4.5 billion years ago. But there are a few notable differences between these two objects, as well. The biggest difference between comets and asteroids, however, is what they are made of.

While asteroids consist of metals and rocky material, comets are made up of ice, dust, rocky materials and organic compounds. When comets get closer to the Sun, they lose material with each orbit because some of their ice melts and vaporizes. Asteroids typically remain solid, even when near the Sun.

Right now, the majority of asteroids reside in the asteroid belt, a region between the orbits of Mars and Jupiter which may hold millions of space rocks of varying sizes. On the other hand, the majority of comets are in the farthest reaches of our Solar System: either 1. in the Kuiper Belt — a region just outside the orbit of the dwarf planet Pluto that may have millions of icy comets (as well as many icy dwarf planets like Pluto and Eris); or 2. the Oort Cloud, a region where trillions of comets may circle the Sun at huge distances of up to 20 trillion kilometers (13 trillion miles).

Answer:

The change in the period of the heated pendulum would be 0.0111 seconds.

The change in the period of a pendulum due to a change in temperature can be calculated using the formula:

ΔT = α * T0 * Δθ

Where:

To solve the problem, we need the coefficient of linear expansion of brass (α). Let's assume α = 19 x 10^(-6) (per degree Celsius).

T0 = 3.94 s (initial period of the pendulum)

Δθ = 149 °C (change in temperature)

ΔT = (19 x 10^(-6) * 3.94 s/°C) * (149 °C)

= 0.0110866 s

Therefore, the change in the period of the heated pendulum is approximately 0.0111 seconds.

Answer:

The  time taken is  \(t = 32.5 \ s\)

Explanation:

From the question we are told that

   The  speed  of  first car is  \(v_1 = 66.7 \ km/h = 18.3 \ m/s\)

    The  speed  of  second car is \(v_2 = 52.7 \ km/h = 14.64 \ m/s\)

   The  initial distance of separation is  \(d = 119 \ m\)

The distance covered by first car is mathematically represented as

     \(d_t = d_i + d_f\)

Here  \(d_i\) is the initial distance which is  0 m/s

  and  \(d_f\)  is the final distance covered which is  evaluated as \(d_f = v_1 * t\)

So

     \(d_t = 0 \ m/s + (v_1 * t )\)

     \(d_t = 0 \ m/s + (18.3 * t )\)

The distance covered by second  car is mathematically represented as

     \(d_t = d_i + d_f\)

Here  \(d_i\) is the initial distance which is  119 m

  and  \(d_f\)  is the final distance covered which is  evaluated as \(d_f = v_2* t\)

       \(d_t = 119 + 14.64 * t\)

Given that the two car are now in the same position we have that

    \(119 + 14.64 * t = 0 + (18.3 * t )\)

   \(t = 32.5 \ s\)

To determine the magnification and orientation of the image formed by a convex mirror, we can use the mirror equation:

1/f = 1/do + 1/di,

where

f = focal length of the convex mirror,

do = object distance (distance from the girl's face to the mirror),

di = image distance (distance from the mirror to the image).

In this case, the girl's face is 5.0 cm from the vertex of the mirror (do = 5.0 cm). The focal length of a convex mirror is half its radius of curvature (f = R/2). Given the radius of the convex mirror is 16 cm, we have:

f = 16 cm / 2 = 8 cm.

Now, we can use the mirror equation to find the image distance (di). Substituting the known values, we have:

1/8 = 1/5 + 1/di.

Simplifying this equation, we find:

1/di = 1/8 - 1/5 = (5 - 8) / (8 * 5) = -3 / 40.

Taking the reciprocal of both sides, we get:

di = -40 / 3 cm.

The negative sign indicates that the image formed by a convex mirror is virtual and upright.

The magnification (m) of the image can be calculated using the formula:

m = -di / do.

Substituting the values, we have:

m = -(-40 / 3 cm) / 5.0 cm = 40 / (3 * 5.0) = 40 / 15.0 ≈ 2.67.

The magnification of the image is approximately 2.67.

The work done by the rock climber when she climbs 12 m in 10 sec with a backpack weighing 600 N is option (d)  7200 J

The distance climbed is 12 meters, and the time taken is 10 seconds. Therefore, the average speed of the climber is:

Average speed = Distance / Time = 12 m / 10 s = 1.2 m/s

The work done is given by the formula:

Work = Force x Distance x cos(theta)

where theta is the angle between the force and the displacement. In this case, the climber is moving vertically upwards, and the force is also vertically upwards, so theta is 0 degrees, and cos(theta) = 1.

Therefore, the work done is:

Work = Force x Distance x cos(theta) = 600 N x 12 m x 1 = 7200 J

Answer:

Explanation:

Main Answer:

The equation acceleration = v/time can be proven using the fundamental definitions of acceleration, velocity, and time. Acceleration is defined as the rate of change of velocity, and velocity is the rate of change of displacement with respect to time. Let's consider an object moving with an initial velocity v0 and final velocity v in a time interval t.

Explanation:

The change in velocity, Δv, can be calculated as the final velocity minus the initial velocity, Δv = v - v0. Similarly, the change in time, Δt, is the final time minus the initial time, Δt = t - t0.

By substituting these values into the equation for acceleration, we have:

acceleration = Δv/Δt

Now, substituting Δv = v - v0 and Δt = t - t0, we get:

acceleration = (v - v0)/(t - t0)

Since v0 and t0 represent the initial velocity and time, respectively, we can rewrite the equation as:

acceleration = (v - v0)/t

By rearranging the equation, we find:

acceleration = v/t

Thus, we have proved that acceleration is equal to v/time.

Answer:That only applies to highly polished surfaces, eg mirrors.

If you take a high quality laser (ie with low divergence) and aim it at a wall, you can see the spot where the laser beam reaches the wall from anywhere with a direct line-of-sight to the spot where the laser beam reaches the wall. This due to micro imperfections on the surface of the wall. At a microscopic level, the wall surface is very rough and pointing in all directions.

As to why, a beam of light bounces of a highly polished surface, I can only surmise that it is essentially due to kinematics, ie the only force opposing the light beam is normal to the surface, hence there no forces along the reflective surface. Since there are no forces along the reflective surface, the speed component of light along the reflective surface remains unchanged. However, on the plane perpendicular to the reflective surface the, the light photons bounce off at the same speed at which the hit the reflective surface because the mass of the reflective surface is much much much larger than the mass of the photons, which means that the reflective surface won’t move at all. Since conservation of momentum requires that momentum after the collision be the same as the momentum before the collision then the only way for that to happen is if the velocity of the photon perpendicular to the reflective surface is of exactly the same magnitude but in the opposite direction. Vector resolution of the speed component of the reflected beam means that the angle of reflection must be the same as the angle of incidence.

A buyer is purchasing a property for $120,000, which has an assessed value of $130,000. If the tax rate is $1.75 per $100, then the buyer will pay approximately $2,091.23 annually in taxes for the property.

To calculate the annual taxes the buyer will pay, we need to determine the property tax based on the assessed value and the tax rate.

Calculate the tax amount per $100 of assessed value:

Tax rate = $1.75 per $100

Tax per 100 = (assessed value / 100) * tax rate

In this case:

Tax per 100 = ($130,000 / 100) * $1.75 = $2,275

Calculate the annual tax amount:

Annual tax = (property price / assessed value) * tax per 100

In this case:

Annual tax = ($120,000 / $130,000) * $2,275 = $2,091.23

Therefore, the buyer will pay approximately $2,091.23 annually in taxes for the property.

The speed of the 8 kg ball must be 0.83 m/s to the right.

To solve this problem, we can use the principle of conservation of momentum, which states that the total momentum of a system of objects is conserved if no external forces act on the system. Before the explosion, the total momentum of the system is zero since both balls are at rest.

After the explosion, the total momentum of the system is still zero, so the momentum of the 5 kg ball to the left must be balanced by the momentum of the 8 kg ball to the right. We can use the formula for momentum, which is momentum = mass x velocity. Let v be the velocity of the 8 kg ball after the explosion.

Then we have

5 kg x (-1.3 m/s) + 8 kg x v = 0

Solving for v, we get:

v = (5 kg x 1.3 m/s) / 8 kg = 0.8125 m/s

Since the velocity is to the right, we get:

Answer:

Approximately \(5.40\; {\rm m\cdot s^{-1}}\) (assuming that \(g = 9.81\; {\rm N \cdot kg^{-1}}\).)

Explanation:

Refer to the diagram attached. There are two forces on this tetherball: tension \(T\) in the string, and weight \(m\, g\)- where \(m\) is the mass of the tetherball.

Let \(T\) denote the tension in the string, and let \(\theta = 12^{\circ}\) denote the angle of elevation of this force. Decompose \(T\!\) into two components: horizontal and vertical:

The tetherball is moving in a horizontal plane, meaning that there is no motion in the vertical direction. Hence, the resultant force in the vertical direction should be \(0\). The vertical component of the tension \(T\, \sin(\theta)\) should exactly balance the weight of the tetherball \(m\, g\):

\(T\, \sin(\theta) = m\, g\).

Hence, the resultant (unbalanced) force on this tetherball would be equal to the horizontal component of tension: \(F_{\text{net}} = T\, \cos(\theta)\).

The length of the rope is \(l = 1.55\; {\rm m}\). Since this rope is also at the angle of \(\theta\) above the horizon, the radius of the circular motion in the horizontal plane would be \(r = l\, \cos(\theta)\).

Since the ball is in a centripetal motion, the resultant force on this ball would also be \(F_{\text{net}} = (m\, v^{2}) / (r)\), where \(v\) is the velocity of the ball.

Equate these two expressions of \(F_{\text{net}}\) to obtain:

\(\displaystyle T\, \cos(\theta) = F_{\text{net}} = \frac{m\, v^{2}}{r}\).

Additionally, \(T\, \sin(\theta) = m\, g\) since the forces on the vertical direction are balanced. Rewrite both this equation and the equation \(T\, \cos(\theta) = (m\, v^{2}) / (r)\) to isolate tension \(T\):

\(\left\lbrace \begin{aligned}& T\, \cos(\theta) = \frac{m\, v^{2}}{r} \\ &T\, \sin(\theta) = m\, g\end{aligned}\right.\).

\(\left\lbrace \begin{aligned}& T = \frac{m\, v^{2}}{r\, \cos(\theta)} \\ &T = \frac{m\, g}{\sin(\theta)}\end{aligned}\right.\).

Solve this system for velocity \(v\):

\(\begin{aligned}\frac{m\, v^{2}}{r\, \cos(\theta)} &= \frac{m\, g}{\sin(\theta)}\end{aligned}\).

Since \(r = l\, \cos(\theta)\):

\(\begin{aligned}\frac{m\, v^{2}}{l\, \cos(\theta)\, \cos(\theta)} &= \frac{m\, g}{\sin(\theta)}\end{aligned}\).

\(\displaystyle \frac{m\, v^{2}}{l\, \cos^{2}(\theta)} = \frac{m\, g}{\sin(\theta)}\).

\(\begin{aligned}v &= \sqrt{\frac{g\, l\, \cos^{2}(\theta)}{\sin(\theta)}} \\ &\approx \sqrt{\frac{9.81\, (\cos(12^{\circ}))^{2}}{(1.55)\, \sin(12^{\circ})}}\; {\rm m\cdot s^{-1}} \\ &\approx 5.40\; {\rm m\cdot s^{-1}}\end{aligned}\).
