The mass and energy of the wood before burning would be equal to the energy and matter of the ash, soot, heat and light after burning.

The law of conservation of energy states that energy can neither be created nor destroyed but can be transformed from one form to another.

While burning of wood, the chemical energy in the wood is released as heat because of the chemical reaction of wood and oxygen.

This type of chemical reaction is called combustion and it requires oxygen. Combustion converts the stored chemical energy in the wood into heat and light energy.

15.3 N

Explanation:

Force = mass x acceleration

= 2.55 kg x 6.00 m/s^2

= 15.3 kgm/s^2 = 15.3 N

The required force to accelerate a 2.55 kg remote-controlled toy car at a rate of 6.00 m/s^2 be 15.3 N.

The definition of force in physics is: The push or pull on a mass-containing item changes its velocity.

An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude. The application of force is the location at which force is applied, and the direction in which the force is applied is known as the direction of the force.

Given parameters:

Mass of the remote-controlled toy car : m = 2.55 kg.

Acceleration of  the remote-controlled toy car :a =  6.00 m/s^2

Now according to Newton's 2nd law of motion,

Force = mass x acceleration

= 2.55 kg x 6.00 m/s^2

= 15.3 kgm/s^2

= 15.3 N

We do not have the value of yo, the initial vertical position of the squirrel (height of the tree limb), so we cannot calculate the exact height of the squirrel above the ground without that information.

What is Velocity?

Velocity is a vector quantity that describes the rate of change of an object's position with respect to time. It specifies both the speed and direction of an object's motion. Velocity is defined as the displacement of an object per unit of time, and it is typically denoted by the symbol "v"

We need to convert the horizontal distance from centimeters to meters and use consistent units in our calculations. Plugging in the given values:

x = 0.186 m

xo = 0 m

vox = 0.1 m/s

Using the horizontal motion equation, we can calculate the time of flight (t) of the nut:

0.186 = 0 + 0.1*t

t = 1.86 seconds

Now, we can use the vertical motion equation to calculate the height (y) of the squirrel:

y = yo + voyt - 0.5g*\(t^{2}\)

Since the squirrel loses its grip and has no initial vertical velocity (voy = 0), we have:

y = yo - 0.5g\(t^{2}\)

Plugging in the known values:

g = 9.8 m/\(s^{2}\)

Im not sure what your question is? Are you asking if humans have contributed to global warming?

The demand for a necessity such as electricity tends to be inelastic. Here's why:Inelastic demand is when changes in price don't affect the quantity demanded as much.

Necessities such as food, water, and electricity often have an inelastic demand, meaning that when the price of the product increases, the quantity demanded does not decrease as much.Explanation:For example, if the cost of electricity increased by 10%, a household might not be able to decrease its use of electricity as much, such as by 10%. The amount of electricity that a household uses might not be affected by price changes because it's a necessity.A vertical demand curve implies that a change in price results in no change in quantity demanded.

Unit elastic refers to a change in price that results in a proportional change in quantity demanded.D elastic refers to the degree of price sensitivity. Demand is said to be elastic when a price change causes a substantial change in demand.

Answer:

\(118\; \rm Hz\).

Explanation:

The frequency \(f\) of a wave is equal to the number of wave cycles that go through a point on its path in unit time (where "unit time" is typically equal to one second.)

The wave in this question travels at a speed of \(v= 295\; \rm m\cdot s^{-1}\). In other words, the wave would have traveled \(295\; \rm m\) in each second. Consider a point on the path of this wave. If a peak was initially at that point, in one second that peak would be

How many wave cycles can fit into that \(295\; \rm m\)? The wavelength of this wave\(\lambda = 2.50\; \rm m\) gives the length of one wave cycle. Therefore:

\(\displaystyle \frac{295\;\rm m}{2.50\; \rm m} = 118\).

That is: there are \(118\) wave cycles in \(295\; \rm m\) of this wave.

On the other hand, Because that \(295\; \rm m\) of this wave goes through that point in each second, that \(118\) wave cycles will go through that point in the same amount of time. Hence, the frequency of this wave would be

Because one wave cycle per second is equivalent to one Hertz, the frequency of this wave can be written as:

\(f = 118\; \rm s^{-1} = 118\; \rm Hz\).

The calculations above can be expressed with the formula:

\(\displaystyle f = \frac{v}{\lambda}\),

(Assumptions: \(g = 9.81\; {\rm m\cdot s^{-2}}\); air resistance on the volleyball is negligible.)

Explanation:

Under the assumptions, acceleration of the volleyball would be \(a = (-g) = (-9.81)\; {\rm m\cdot s^{-2}}\) during the entire flight. (This value is negative since the ball is accelerating downwards- toward the ground.)

By the time the volleyball hits the ground, the volleyball would be at a position \(2.0\; {\rm m}\) below where it was launched. In other words, the (vertical) displacement of the volleyball during the entire flight would be \(x = (-2.0)\; {\rm m}\). (Negative since the ball is below where it was launched.)

Apply the SUVAT equation \((v^{2} - u^{2}) = 2\, a\, x\) to find the velocity of the volleyball right before hitting the ground. In this equation:

Rearrange this equation and solve for the velocity right before landing, \(v\). Note that because \(v\!\) is raised to the power of \(2\) in \((v^{2} - u^{2}) = 2\, a\, x\), both \(v = \sqrt{u^{2} + 2\, a\, x}\) and \(v = -\sqrt{u^{2} + 2\, a\, x}\) could satisfy this equation. However, \(v\!\!\) needs to be negative since the volleyball would be travelling downwards before reaching the ground.

Therefore, right before reaching the ground, velocity of the volleyball would be:

\(\begin{aligned} v &= -\sqrt{u^{2} + 2\, a\, x \\ &= -\sqrt{(6.0)^{2} + 2\, (-9.81)\, (-2.0)} \; {\rm m\cdot s^{-1}} \\ &\approx (-8.67)\; {\rm m\cdot s^{-1}}\end{aligned}\).

In other words, velocity of this volleyball has changed from \(u = 6.0\; {\rm m\cdot s^{-1}}\) (upwards) to \(v \approx (-8.67)\; {\rm m\cdot s^{-1}}\) (downwards) during this flight. Divide the change in the velocity \((v - u)\) by the rate of change in velocity \(a = (-9.81)\; {\rm m \cdot s^{-2}}\) to find the duration of this flight:

\(\begin{aligned}t &= \frac{v - u}{a} \\ &\approx \frac{(-8.67) - 6.0}{(-9.81)}\; {\rm s} \\ &\approx 1.5\; {\rm s}\end{aligned}\).

The mass of Rhea, one of Saturn's moons, can be calculated using its radius and acceleration due to gravity at its surface.

The mass of  Rhea, one of Saturn's 62 moons, has a radius of 764 km and an acceleration due to gravity of 0.265 m/s2 at its surface. Using the formula for acceleration due to gravity, GM/R² = g, where G is the gravitational constant, M is the mass of the object (in this case, Rhea), R is the radius of the object (in this case, the radius of Rhea), and g is the acceleration due to gravity at the surface of the object, we can calculate the mass of Rhea to be approximately 2.31 x 10²¹ kg.

This calculation assumes that Rhea has a uniform density throughout its interior, which is a common assumption for small celestial bodies like moons.

A slit of width 0.01 mm has light of wavelength 600 nm passing through it onto a screen 60 cm away.  The central maximum will be 7.2 cm .

The central maximum is the brightest central portion of the diffraction pattern. The central maximum is the widest and has the maximum intensity.

The diffraction pattern involves a central bright fringe, also known as the central maxima. Furthermore, central maxima is surrounded by dark and bright lines known as the secondary minima and maxima.

Given

slit width = 0.01 mm = .01 * \(10^{-3}\) m

wavelength = 600 nm = 600 * \(10^{-9}\) m

distance from screen = 60 cm = 60 * \(10^{-2}\) m

width of central maxima = (2 * lambda * D) / d

                                        = 2 * 600 * \(10^{-9}\) * 60 * \(10^{-2}\)  / .01 * \(10^{-3}\)

While there are a few distinctions in the geography of Mars and Earth, these are not the essential justifications for why volcanoes on Mars will generally be bigger than those on The planet. One justification behind the bigger size of Martian volcanoes is the shortfall of plate tectonics, which permits magma to gather over the long run in a solitary area.

One more component is the lower surface gravity on Mars, and that implies that magma can rise all the more effectively through the outside and emit in bigger volumes.

Moreover, numerous Martian volcanoes have encountered rehashed ejections over a significant stretch of time, which can likewise add to their huge size. In any case, the separation from the Sun isn't an element that would influence the size of Martian volcanoes contrasted with Earth's.

Answer:

Explanation:

For the block placed on the table, there are several force acting on the body along the horizontal and vertical axis. All this forces tends to keep the body in a state of equilibrium.The forces acting along the horizontal are the moving force (Fm) and the frictional force (Ff).

Frictional force are forces that acts opposite to the force that causes the body to move (moving force).

If Lien uses a spring scale to pull a block toward the right across the lab table and the scale reads 8 N, this means that the force that causes the body to move is the 8N force (moving force).

Taking the sum of force along the horizontal;

\(\sum fx = ma_x\)

Since the body is static, max = 0

\(\sum fx = 0\\fm+(-Ff)= 0\)

Note that the frictional force acts is the force of opposition acting in the negative x direction.

\(fm = 0+Ff\\fm = Ff\)

Since Fm = 8N, Ff will also be equal to 8N.
