Answer:

it's B

Explanation:

Elastic potential energy is energy stored as a result of applying a force to deform an elastic objects. The energy is stored until the force is removed and the object springs back to it's original shape, doing work in the process. The deformation could involve compressing, stretching or twisting the object

Answer:

Anything that has mass is made up of matter – an all-encompassing word for atoms and molecules that make up our physical world. We describe this matter as existing in states (sometimes referred to as phases). Most people are familiar with three states of matter – solids, liquids and gases – but there are two more that are less commonly known but just as important – plasmas and Bose-Einstein condensates

Answer:

The value is [tex]T_t = 2.5659 \ s[/tex]    

Explanation:

From the we are told that  

         The initial speed of the object is  [tex]u = 8 \ m/s[/tex]

         The greatest height it reached is  [tex]h = 15 \ m[/tex]

Generally from kinematic equation we have that

      [tex]v^2 = u^2 + 2gH[/tex]

At maximum height v  =  0 m/s

So

      [tex]0^2 = 8^2 + 2 * - 9.8 * H[/tex]

=>    [tex]H = 3.27 \ m[/tex]

Here H is the height from the initial height to the maximum height

So the initial height is mathematically represented as  

      [tex]s = h - H[/tex]

=>    [tex]s = 15 - 3.27[/tex]

=>    [tex]s = 11.73 \ m[/tex]

Generally the time taken for the object to reach maximum height is mathematically evaluated using kinematic equation as follows

            [tex]v = u + (-g) t[/tex]

At maximum height v  =  0 m/s

           [tex]0 = 8 - 9.8t[/tex]

=>         [tex]t = 0.8163 \ s[/tex]

Generally the time taken for the object to move from the maximum height to the ground is mathematically using kinematic equation as follows

       [tex]h = ut_1 + \frac{1}{2} gt_1^2[/tex]

Here the initial velocity is  0 m/s given that its the velocity at maximum height

Also  g is positive because we are moving in the direction of gravity  

So

       [tex]15 = 0* t + 4.9 t^2[/tex]

=>      [tex]t_1 = 1.7496[/tex]

Generally the total time taken is mathematically represented as

          [tex]T_t = t + t_1[/tex]

=>        [tex]T_t = 0.8163 + 1.7496[/tex]

=>        [tex]T_t = 2.5659 \ s[/tex]            

Answer:

rock of mass m is dropped to the ground from a height h. A second rock, with mass 2m, is dropped from the same height. When the second rock strikes the ground, what is its kinetic energy? (a) Twice that of the first rock, (b) four times that of the first rock, (c) same as that of the first rock, (d) half as much as that of the first rock, (e) impossible to determine.

If a  rock is dropped into a canyon that is 0.3 km deep, then the time taken by the rock to hit the bottom of the canyon would be 7.82 seconds.

There are three equations of motion given by  Newton

v = u + at

S = ut + 1/2 × a × t²

v² - u² = 2 × a × s

Keep in mind that these calculations only apply to uniform acceleration.

As given in the problem, if a rock is dropped into a canyon that is 0.3 km deep.

By using the second equation of motion given by Newton,

S = ut + 1/2at²

300 = 0 + 0.5 × 9.8 × t²

t² = 300 / 4.9

t = 7.82 seconds

Thus,  the time taken by the rock to hit the bottom of the canyon would be 7.82 seconds.

Answer:

im pretty sure its because wax has i higher melting point therefore it would cool quicker if the temperature dropped more. water has a lower melting point so it takes longer to freeze i think. i hope this helps

Water and wax freeze from different directions due to the unique properties and behaviors of these substances.

Water:

When water freezes, it undergoes a phase transition from a liquid to a solid state.

Unlike most substances, water exhibits an unusual property known as the "anomalous expansion of water" or "density anomaly." This anomaly is caused by the hydrogen bonding between water molecules.

As the water cools down, its molecules begin to slow down and move closer together. This causes the density of the water to increase. However, as the water reaches around 4 degrees Celsius (39 degrees Fahrenheit), it starts to behave differently.

The hydrogen bonds between water molecules become more organized and stable, causing the water to expand and become less dense.

Wax:

Wax, on the other hand, does not exhibit the same density anomaly as water. When wax undergoes solidification, it follows a different pattern due to its molecular structure and the way its particles arrange themselves.

Wax typically consists of long, nonpolar hydrocarbon chains. As it cools, the wax molecules start to lose kinetic energy, slowing down their movement.

The intermolecular forces between the wax molecules become stronger, causing them to come closer together.

In summary, water freezes from the top due to its density anomaly, with the less dense, expanded water rising and forming a layer of ice on the surface.

Wax, however, freezes from the bottom as its molecules arrange and bond together, gradually solidifying upwards. These differences in freezing behavior are influenced by the distinct properties and molecular structures of water and wax.

Answer:

28 N

Explanation:

From the question given above, we were told that 10 N force and 18 N force act in the same direction on the object.

The net force acting on the object can be obtained by simply adding both forces together since they both act on the object in the same direction. This is illustrated below:

Force 1 (F₁) = 10 N

Force 2 (F₂) = 18 N

Net force (Fₙ) =?

Fₙ = F₁ + F₂ (since they both act in the same direction)

Fₙ = 10 + 18

Fₙ = 28 N

Therefore, the net force acting on the object is 28 N.

Answer:

The Earth's rotation which produces Coriolis force is the responsing factor for the formation and movement of different global winds.

The cause of the global winds is due to the rotation of the earth that produces the Coriolis force factor for the formation and movement of global winds.

The global wind pattern is formed by the movement of the earth and they are polar easterlies, prevailing westerlies and the trade winds.

Each of them occurs at about 30 degrees of latitude. Hence they form wind belts. The Coriolis effect that is created due to the rotation of the earth is a fact that leads to the movement of global winds.

Acceleration due to gravity depends directly on the mass of Earth and inversely to the square of radius of Earth.

Answer:

9.8 m/s2

Explanation:

Acceleration due to gravity is the acceleration gained by an object due to the gravitational force. Its SI unit is m/s 2. It has both magnitude and direction, hence, it’s a vector quantity. Acceleration due to gravity is represented by g. The standard value of g on the surface of the earth at sea level is 9.8 m/s2.
