what is types of motion ​

A wedge is like a ramp that can work while in motion.

As a tool for raising or lowering a load, an inclined plane, also referred to as a ramp, is a flat supporting surface that is tilted at an angle from the vertical direction with one end higher than the other. One of the six traditional simple machines that Renaissance scientists defined is the inclined plane.

Heavy loads are transported over vertical obstacles using inclined planes. Examples include a ramp used to load cargo into a truck, a pedestrian ascending a ramp, or an automobile or train ascending a grade.

Less force is needed to lift an object up an inclined plane than to lift it straight up, but the distance travelled is greater. Hence, a wedge is like a ramp that can work while in motion.

Answer:

the energy increases 4 times

Explanation:

A spring has an elastic potential energy that is given by the expression

          K_e = ½ K (x-x₀)²

where x is the distance from the equilibrium point and k is the return constant

if the spring is stretched at  x-x₀ = 2x₀, the energy value

        K_e = ½ k (2x₀)²

        K_e = ½ k 4 x₀²

        K_e = 4 (½ k x₀²)

        [tex]\frac{K_e}{ \frac{1}{2} k x_o^2}[/tex] = 4

therefore the energy increases 4 times

The energy stored in the spring changes by a factor of 4

The formula for calculating the energy stored in the spring is expressed as:

[tex]E=\frac{1}{2}ke^2[/tex]

If the spring is stretched to twice the length of its equilibrium position

[tex]E_2=\frac{1}{2}(2k)^2\\E_2=\frac{1}{2}4k^2[/tex]

Take the ratio of the energy stored in the spring

[tex]\frac{E_2}{E} =\frac{1/2(4kx^2)}{1/2kx^2}\\ \frac{E_2}{E} =\frac{4}{1}\\E_2 = 4E[/tex]

This shows that the energy stored in the spring changes by a factor of 4

The farther you live from an ocean, the more likely you will have a continental climate where there are extreme temperature differences in summer and winter

Inland regions have continental climates. To feel the impacts of ocean water, they are too distant from oceans. Between 40 and 70 degrees north latitude, continental climates are typical.

Northern Ukraine, eastern Belarus, Russia, the majority of Finland, and northern Sweden all have climates that are classified as continental. The northeast has the coldest winters and warmest summers, with winters being significantly colder, longer, and covered in more snow than in western Europe.

Given data ,

Let the land be situated at a place where it is farther away from the ocean

Now , there will be extreme temperature differences during the summer and the winter time

And , winters may be quite cold and summers can be very hot in continental climes. As there is less water in the continental environment than there is in marine climates, the temperatures are not as warm.

Hence , the continental climate takes place the farther you live from an ocean

Answer:

True.

Explanation:

Energy can be defined as the ability (capacity) to do work. The two (2) main types of energy are;

a. Gravitational potential energy (GPE): it is an energy possessed by an object or body due to its position above the earth.

b. Kinetic energy (KE): it is an energy possessed by an object or body due to its motion.

Furthermore, the mechanical energy of a physical object or body is the sum of the potential energy and kinetic energy possessed by the object or body.

Mathematically, it is given by the formula;

Mechanical energy = G.P.E + K.E

Mechanical energy that has been ‘lost' to friction isn't really lost. It just is no longer in its mechanical form. This is ultimately in accordance with the law of conservation of energy, which states that energy cannot be destroyed but can only be converted or transformed from one form to another.

Hence, Mechanical energy that has been ‘lost' to friction isn't really lost but converted into heat energy.

Explanation:

If the roller coaster car in the above problem were moving at twice the speed, then 16000 Joules is the new kinetic energy.

Kinetic energy is a type of power that a moving object or particle possesses. An item accumulates kinetic energy when work, which involves the transfer of energy, being done on it by exerting a net force.

A object in motion or particle has kinetic energy, which relies on both its mass and its rate of motion. Any combination of movements, including translation, rotation along an axis, and vibration, may constitute the kind of motion.

kinetic energy= ½mv²

v =4m/s

m= 2000kg

KE = ½ (2000) (4)²

    =16000 Joules

Therefore, If the roller coaster car in the above problem were moving at twice the speed, then 16000 Joules is the new kinetic energy.
