Use the formula for the law of universal gravitation to calculate the gravitational force between the large ball and the small ball.

The component of the force acting in the direction of an object's motion determines how much force is doing work on that object. The "parallel component" of the force is referred to as this.

A force that is applied perpendicular to an object's motion has no effect since it does not add to the object's kinetic energy.

It follows that the force exerted on the item will increase if the applied force's direction is adjusted to make it more parallel to the direction of motion.

The amount of force accomplishing work will decrease, on the other hand, if the direction of the applied force becomes increasingly perpendicular to the direction of motion.

Take the movement of a box across a rough surface as an illustration.

Only a fraction of the force will be parallel to the surface of the force delivered at a 45-degree angle to the surface, contributing to the motion of the box.

Answer:

The cumulative distance that the bird travel is 13.33 Km

Explanation:

Given that,

Velocity of runner = 3.4 km/hr

Distance = 8 km

Velocity of bird = 17 km/hr

Let x is the distance from the origin where the runner run into the bird

We need to calculate the value of x

Using time of runner and bird

\(t_{r}=t_{b}\)

\(\dfrac{d_{r}}{v_{r}}=\dfrac{d_{b}}{v_{b}}\)

Put the value into the formula

\(\dfrac{x}{3.4}=\dfrac{8+(8-x)}{17}\)

\(17x=3.4\times8+3.4(8-x)\)

\(17x=27.2+27.2-3.4x\)

\(17x+3.4x=54.4\)

\(x=\dfrac{54.4}{20.4}\)

\(x=2.67\)

We need to calculate the cumulative distance that the bird travel

Using distance of bird

\(d_{b}=16-x\)

Put the value into the formula

\(d_{b}=16-2.67\)

\(d_{b}=13.33\ km\)

Hence, The cumulative distance that the bird travel is 13.33 Km

The eccentricity of an orbit when both focal points are located at the sun is zero.

What is an orbit?

An orbit is the trajectory, or path, of an object that revolves around another object, the center of mass or a gravitational point. All planets orbit the sun, and the moon orbits the earth, for example, An elliptical orbit is the shape of many planetary orbits.

As a result, the eccentricity of the orbit is significant.

What is Eccentricity?

The degree of circularity of an orbit is referred to as its eccentricity. When the distance between the two foci is divided by the length of the major axis, eccentricity is calculated.

A perfectly circular orbit has an eccentricity of zero.

An ellipse with an eccentricity of 1 is a parabolic orbit. When eccentricity is greater than one, the orbit is hyperbolic.

The eccentricity of an orbit when both focal points are located at the sun:

Since there is only one focus, and the center of the sun is located there, the eccentricity of such an orbit is zero. Because there is only one focus, the distance between the two foci is also zero.

As a result, a planet's orbit with a sun-centered focus is always circular.

To find the magnitude of the Earth's centripetal acceleration as it travels around the Sun, we can use the formula for centripetal acceleration: a = (v^2) / r

where a is the centripetal acceleration, v is the velocity of the Earth, and r is the radius of the Earth's orbit. The velocity of the Earth can be calculated using the formula: v = (2πr) / T. where T is the period of the Earth's orbit, which is the length of a year. Given that a year has 365 days, we can convert it to seconds by multiplying by 24 (hours), 60 (minutes), 60 (seconds): T = 365 days * 24 hours/day * 60 minutes/hour * 60 seconds/minute. Now, we need to find the radius of the Earth's orbit. The average distance between the Earth and the Sun, known as the astronomical unit (AU), is approximately 149.6 million kilometers or 1.496 × 10^11 meters. Plugging the values into the equations: T = 365 * 24 * 60 * 60 = 31,536,000 seconds. r = 1.496 × 10^11 meters. Calculating the velocity: v = (2π * 1.496 × 10^11) / 31,536,000 ≈ 29,788 m/s. Finally, we can calculate the centripetal acceleration: a = (v^2) / r = (29,788^2) / (1.496 × 10^11) ≈ 0.00593 m/s^2. Therefore, the magnitude of the Earth's centripetal acceleration as it travels around the Sun is approximately 0.00593 m/s^2.

The maximal angle is found to be 22 degrees (option d).

The value is found to be 38 J (option b).

a) For the body to not slide down the inclined surface, the force of gravity acting downward must be balanced by the maximum static friction force acting upward along the surface. The maximum static friction force can be determined using the equation f_s = μ_s * N, where μ_s is the coefficient of static friction and N is the normal force. The normal force can be calculated as N = m * g * cos(θ), where m is the mass of the body, g is the acceleration due to gravity, and θ is the inclination angle. Setting the force of gravity equal to the maximum static friction force, we can solve for the maximal angle θ. Plugging in the values, we find that the maximal angle is approximately 22 degrees (option d).

b) After the collision, the two bodies stick together and move as one. The principle of conservation of momentum states that the total momentum before the collision is equal to the total momentum after the collision. Mathematically, this can be written as m₁ * v₁ = (m₁ + m₂) * v₂, where m₁ and m₂ are the masses of the two bodies, v₁ is the initial velocity of the first ball, and v₂ is the final velocity of both balls together. We can solve for v₂, which will be the final velocity of the combined bodies. Once we have v₂, we can calculate the kinetic energy using the equation KE = 0.5 * (m₁ + m₂) * v₂². Plugging in the given values, we find that the kinetic energy after the collision is approximately 38 J (option b).

The horizontal component of the average force, in newtons.
a = (-18 m/s) / t

To calculate the horizontal component of the average force on the person during the collision, we'll use the formula:

F = m * a

where F is the force, m is the mass, and a is the acceleration. Since we're given the person's mass (77.5 kg) and the initial velocity of the car (18 m/s), we need to find the acceleration during the collision.

Acceleration can be found using the equation:

a = (v_f - v_i) / t

where v_f is the final velocity, v_i is the initial velocity, and t is the time taken for the collision. Assuming the car comes to a stop after the collision (v_f = 0), the equation becomes:

a = (-18 m/s) / t

We need the collision time (t) to calculate acceleration. This information isn't provided in the question, so we can't calculate the exact force. However, you can use the formula F = m * a to find the horizontal component of the average force once you have the collision time.

Answer:

300m/s

Explanation:

velocity = frequency(wavelength)

Since 10 waves pass a point each second, frequency is 10

therefore, speed = (10)(30 = 300m/s

The speed of light can be determined using the frequency and wavelength of that wave. The speed of the wave with the wavelength of 30 m and frequency of 10 s⁻¹ is 300 m/s.

The wavelength of a wave is the distance that can travel  per unit time or it is the distance between two consecutive crests or troughs of the wave.

The wavelength in inversely proportional to the frequency of the wave. Frequency of a wave is the number of waves passing per second.

The relation between wavelength and frequency to the speed of the wave is written as follows:

\(c = v \lambda\)

Thus speed of the wave is the product of its frequency and wavelength. Given that 10 waves pass per second. Thus, frequency is 10/s. Wavelength is 30 m . The speed is calculated as follows:

Speed of the wave = 30 × 10

                                = 300 m/s.

Therefore, the speed of the wave with the wavelength of 30 m and frequency of 10 s⁻¹ is 300 m/s.
