Answer:
100m
Explanation:
i think this is the answer because the formula for distance is
d=speed×time in this case the speed is 10m/s and the time is 10s therefore the distance will be
10m/s×10s
=100m
I hope this helps
Answer:
F=-100N; a=1.3m/s^2
Explanation:
Force is being made by student, so wall counteracts that force by not moving so it is equally opposite.
Answer:
10.31 m
Explanation:
To find the result you have to use the formula: h = p / eg.
Where: e = 1000Kg/m^3 g=9.8m/s^2 p= 1.01 * 10^5 Pa
The calculation will be:
h= 1.01 * 10^5 / (1000kg/m^2) * (9.8m/s^2)
h= 10.31 m
Answer:
400watts
Explanation:
Power is defined as the amount of energy expended in a specific time. It is also defined as the change in work done with respect to time.
Mathematically,
Power = Workdone/time
Work done = Force×distance
Power = Force × Distance/Time
Given force = mass× acceleration due to gravity
Force = 60×10 = 600N
Distance covered = 4.0m
Time taken = 6.0seconds
Power expended = 600×4/6
Power expended = 400Watts
The average mechanical power (in W) required to do this is 400Watts
Answer:
fem = -A β
Explanation:
Faraday's law gives the induced electromotive source (emf)
fem =
the magnetic flux is
= B. A = B A cos θ
the bold are vectros. In this case the normal to the ring is parallel to the magnetic field so the angle is zero cos 0 = 1, also the area of the ring is constant
fem = -A
we carry out the derivative of the function B = α + β t
fem = -A β
so we see that there is an electromotive force in the ring.
