A ______ is like a ramp that can work while it is in _____.
Answers
A wedge is like a ramp that can work while in motion.
What is ramp?
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.

If a spring is stretched to twice the lengtj of its equilibrium position, by what factor does the energy stored in the spring change?
Answers
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
What is continental climate?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

Mechanical energy that has been ‘lost' to friction isn't really lost. It just is no longer in its mechanical form. True or False
Answers
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.

If the roller coaster car in the above problem were moving at twice the speed, then what would be its new kinetic energy
Answers
Answer:
it would move faster
Explanation:
If the roller coaster car in the above problem were moving at twice the speed, then 16000 Joules is the new kinetic energy.
What is 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.

Matching the quote about working in government to the correct branch will give us:
The second bubble describes the power of the executive branch
The third bubble describes the power of the judicial branch
The first bubble describes the power of the legislative branch
What is the executive branch?The power of the Executive Branch is vested in the President of the United States, who also acts as head of state and Commander-in-Chief of the armed forces.
The executive branch or is the part of government that enforces law, and has responsibility for the governance of a state.
In political systems based on the principle of separation of powers, authority is distributed among several branches (executive, legislative, judicial)—an attempt to prevent the concentration of power in the hands of a single group of people.
The executive enforces the law as written by the legislature and interpreted by the judiciary.
The executive can be the source of certain types of law, such as a decree or executive order. Executive bureaucracies are commonly the source of regulations.
What is the judicial branch?The third branch of government is the Judicial branch. The Judiciary is made up of courts -- Supreme, Circuit, the magistrate (local) and municipal (city) courts. The Judicial branch interprets the laws.
The state judges are elected by the citizens rather than being appointed. They also run for their office as members of a political party.
The judiciary is the system of courts that interprets, defends, and applies the law in the name of the state. The judiciary can also be thought of as the mechanism for the resolution of disputes.
In many jurisdictions, the judicial branch has the power to change laws through the process of judicial review.
