Answer:
d = 27.7 m
Explanation:
Here the car is driving on the inclined plane
So here we can say that work done by the gravity and work done by friction is equal to change in kinetic energy of the system
So here we can write it as
now we have
m = 1700 kg
<h2>Movement of Continents</h2>
Explanation:
- Alfred Wegener was a German astronomer who proposed the "continental drift" hypothesis in 1910.
- Alfred Wegener was not able to explain the movements of the continent in how and in which way they are moved.
- He failed in an attempt to explain with the use of tides made the theory undefinable fully.
- Also, the major problem with Wegener's theory of Continental Drift was that there was no proper explanation of a mechanism.
(0.5)×(0squared)×(3)=(1.5j)
Answer:
a 10 kg elephant moving at 1 m/s
Explanation:
because kinetic energy depend on how fast an object moves and also depend on the gravitational force which include the weight.
Choice 'b' is one possible way to state
Newton's second law of motion.
The other choices are meaningless.
