Answer:
The kinetic energy of the wagon is 967.0 J
Explanation:
Given that,
Force = 120 N
Mass = 55 kg
Height = 8 m
We need to calculate the kinetic energy of the wagon
Using newtons law
Using equation of motion
Where,
v = final velocity
u = initial velocity
s = height
Put the value in the equation
Now, The kinetic energy is
Hence, The kinetic energy of the wagon is 967.0 J
Light bulbs can be used to indicate current flow in a circuit. The brightness of a bulb is proportional to the amount of current passing throw it. The figure shows a battery, a switch, two light bulbs, and a capacitor that is initially uncharged The brightness of a lightbulb is given by its power. P = I2R, and so brightness depends on current and resistance
<h3>What is
current flow?</h3>
A stream of charged particles, such as electrons or ions, traveling through an electrical conductor or a vacuum is known as an electric current. The net rate of electric charge flowing through a surface or into a control volume is how it is calculated. [622 Charge carriers, which can be any of a number of particle kinds depending on the conductor, are the moving particles. Electrons flowing over a wire are frequently used as charge carriers in electric circuits. They can be electrons or holes in semiconductors. Ions are the charge carriers in an electrolyte, whereas ions and electrons are the charge carriers in plasma, an ionized gas.

The answer to the question is
<span>PE = W = 1/2 (kx^2)
16.2 = </span>1/2 (k(0.30)^2)
k = 360 J/m^2
A continental tropical air mass is dry and hot. It is formed over the land and in hot tropical areas. Summer months are when this kind of warm air mass is most noticeable and it can stay for a lengthy period of time.
A calorimeter is can be used to measure the amount of heat released or involved in a chemical reaction. Whereas thermometer can only measures temperature or hotness of a substance. It cannot be used to measure the thermal rate or amount of heat energy of a reaction.
