Because trees get thier nutrients and energy from the sun. They absorb it through the leaves and it makes them grow strong. then someone cuts down the tree and makes the wood for your fire. So, the fire burns the wood that was made from the tree that got nutrients and grew from the sun.
Answer:
Increase
Explanation:
Energy of given as follows
E = h f
Where f is the frequency of incident light
when high frequency light falls then it will increase the number of produce photon and that increase in number of photon will lead to increase in the number of electron.When number of electron will increase it mean that current will also increase.
So we can say that when frequency increase then current will increase.
C.
It is a motion with uniform acceleration, meaning that the acceleration will not change.
The object is thrown upwards with a positive velocity. This shows that the upward direction is positive. The object will decelerate due to gravity at a magnitude of 9.81 m/s2. Therefore, the acceleration is -9.81 m/s2.
Note that even though the velocity of the object is momentarily 0 m/s at maximum height, there is still a constant acceleration.
This allows the object first decelerate upwards, then change direction at max height, and finally accelerate downwards. So in this case, the acceleration is always negative and unchanged.
Answer:
Answer 11
Explanation:
. Newton's law of gravitation, statement that any particle of matter in the universe attracts any other with a force varying directly as the product of the masses and inversely as the square of the distance between them
