The scientific law of one organism feeding off to other where energy is transferred from one form to another is known as the law of conservation of energy.
Explanation-
Energy from the the highest energy source that is sun is absorbed by plants to convert it into food (i.e a form of energy). plants are the only ones that can convert sunlight into another form of energy directly.
The animals and organisms that feed off of the plants take some part of this energy for their life cycles and then the animals that feed off of these animals again take some part of this energy and carry on with their life cycle, this is how energy from sun (highest source) is transferred to different organisms by Just changing form.
Yes because of the temperature and the elements that moves
Answer:
The reason is that the value of static friction between two contact surfaces is always greater than that of the kinetic friction between the same surfaces.
Explanation:
When a body is at rest on another body, the two surfaces exert a force called static friction that prevents the surfaces from sliding.
When one of the body is in motion, the two contact surfaces exert a force between them in the direction opposite to the direction of motion is called kinetic friction. It opposes the motion of the body.
The kinetic friction acts on the surfaces only when there is a motion associated with the surface with respect to the other.
The equation for static and kinetic friction is
<em> F = μₓ · η
</em>
Both static and kinetic forces have the same dimension. Only they differ is in the value of the coefficient of friction.
On analyzing the friction between two surfaces, the static friction of the two contact surfaces is always greater than that of their kinetic friction.
Hence, it is more difficult to move an object at rest, than to keep an object moving with uniform motion.
First, we need to calculate for the height where the mailbag
was dropped.
h = 3.50 * t^3
at t = 1.75 s, h is:
h = 3.50 * (1.75)^3
h = 18.758 m
Then we can use the equation to solve for time:
h = v0t + 0.5gt^2
where v0 is initial velocity = 0, t = time, g =
acceleration due to gravity
18.758 m = 0 + 0.5 * (9.81 m/s^2) * t^2
t^2 = 3.8242
t = 1.96 s
<span>So the mailbag reaches the ground after 1.96 seconds</span>
