Explanation:
A force that leads to movement of an object is known as work.
The energy present in an object due to its position in a gravitational field is known as gravitational potential energy.
Kinetic energy is the energy obtained by an object due to its motion.
For example, when Jerome is swinging on a rope then there occurs movement in the swing due to which the swing has kinetic energy.
Since, a force has been applied on the swing to make it move. Hence, a work is also done.
Therefore, we can conclude that if Jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, work is being done.
Fossil Fuels:
Coal and Oil
How they are formed:
Coal is formed from big plants, from a long time ago. When the big plants died, they formed layers at the bottom of swamps and the dirt began to pile up and it formed Coal.
Oil is a fossil fuel that has been formed from a large amount tiny plants and animals such as algae and zooplankton.
Answer:
Wavelength = 5.77 * 10^-5 meters.
Explanation:
Given the following data:
Frequency of light = 5.2 *10^12 Hz
We know that the Speed of light = 3.0 * 10^8 m/s
To find the wavelength of light;
Mathematically, wavelength is calculated using this formula;
Substituting into the equation, we have;
Wavelength = 5.77 * 10^-5 meters.
Theyre all in constant motion
