One of the most common energy transformations is the transformation between potential energy and kinetic energy. In waterfalls such as Niagara Falls, potential energy is transformed to kinetic energy. The water at the top of the falls has gravitational potential energy. As the water plunges, its velocity increases. Thanks to google!!!! LOL :)
Answer:
In contrast, the intrinsic brightness of an astronomical object, does not depend on the distance of the observer or any extinction. The absolute magnitude M, of a star or astronomical object is defined as the apparent magnitude it would have as seen from a distance of 10 parsecs (33 ly).
Explanation:
I believe you are right! If the wheels were bigger then they would add more mobility to the wagon with less effort because Allowing it to take more weight (from the wagon) allowing you to pull much easier.
Have a blessed day!
Answer:
111.657596
Explanation:
The expression of volume is given by

Partially differentiating the term we get

m = 0.100

The partial molar volume of glucose is 111.657596
Answer:
maximum kinetic energy is for Pulley
e) The pulley
Explanation:
Let 4 kg block is moving downwards with speed "v" so we can say that 2 kg block will move upwards with same speed "v"
Now we know that pulling is in pure rotational motion
so we will have


now kinetic energy of each is given as
For 4 kg block

for 2 kg block

For pulley



So maximum kinetic energy is for Pulley
