The time taken for anna to move the box the distance of 9.72 meters is 25.9 seconds. The correct option is c.
<h3>What is force?</h3>
The force is the action of push or pull to move or stop an object.
Anna pushes a box with a force of 8.00 newtons. she generates a power of 3.00 watts.
Force is related to power by the relation
Force = Power / Velocity
Put the values, we get
8 = 3/V
V = 0.375 m/s
Velocity is defined as the ratio of distance and the time taken.
The box is moved by the distance of 9.72 meters. So, time taken is
V = d/t
0.375 = 9.72/t
t =25.9 seconds.
Thus, time taken for anna to move the box the distance of 9.72 meters is 25.9 seconds.

Answer: depth= 1875m
Explanation: divide t by 2 because its echo it will go and come back thats why we divide it with 2
Then apply formula Depth(d)=velocity (v)/time (t)
Putting values we get ,
d=1500/0.4
d=1875m
To what? You did not put the question.
Answer:4 times
Explanation:
Given
Balls are identical and thrown with initial velocity lets say u and 2u because the other ball is thrown with twice the velocity of first
Maximum height reached by first ball is h which is given by
For second ball
Thus height gained by second ball will be 4 times of first ball.
If a bus travels 30 km in 1/2 hr, then in one hr, he can travel twice the distance.
30*2=60 km
Final answer: 60 km per hr
