Answer: The correct answer is "work".
Explanation:
The expression for the work done in terms of force and displacement is as follows;
W= Fd
Here, W is the work done, F is the applied force and d is the displacement.
If the force is applied to an object and the object is displaced to some distance then the work is done.
It is given in the problem that force is applied to an object and the object is moved over a distance in the same direction of the applied force". The given statement is the definition of work. The work done can be zero, negative and positive. In the given case, the positive work is said to be done as the direction of the applied force and the distance moved by the object are same.
Therefore, the correct option is (d).
Answer:
The alligator will take t = 10 s to reach the final speed of 35 m/s
Explanation:
As we know that the initial speed of the alligator is 5 m/s
then it accelerate by given acceleration to reach the final speed of 35 m/s
so we will have



now we have



Correct answer would be d
Because glass have molecules that are more closely packed together than water therefore when gaining heat the glass would gain heat faster and therefore exapand faster.
