Good morning.
Yes, it is possible.Energy is a scalar quantity. The value of the potential energy is calculated the following way:
Where
m is mass,
g is the acceleration of gravity and
h is the height.
Note that the height depends on the adopted referential, therefore, if we adopt, for example, a referential on the floor, if we dig a hole that has a depth of 1 meter, a ball that is put inside the hole will have negative potential energy due to the adopted referential, since
h is negativa in this case.
<span>A fault slip is the distance of motion, or displacement, along a fault during an earthquake. They can be classified by their relation to the horizontal, for example, if the fault slip happens primarily vertically it is a dip slip.</span>
Answer:
50N
Explanation:
Given parameters:
Mass of the bike = 10kg
Acceleration = 5m/s²
Unknown:
Force on the bike = ?
Solution:
To solve this problem, we apply Newton's second law of motion.
Force = mass x acceleration
Force = 10 x 5 = 50N
The water is already at its boiling point
, therefore we don't need additional heat to increase its temperature. Instead, we have to give the heat necessary to make it evaporate. The energy needed is equal to
where
m is the mass of the water
Lv is the latent heat of evaporation
The latent heat of evaporation of water is
, and the mass of this sample of water is
, therefore the heat needed to vaporize the water is
