F = force applied to hold the weight of the bowling ball = weight of the bowling ball = 75 N
d = distance through which the bowling ball is moved horizontally = 10 meter
θ = angle between the force in vertically upward direction and displacement in horizontal direction = 90
W = work done on the bowling ball
work done on the bowling ball is given as
W = F d Cosθ
inserting the values
W = (75) (10) Cos90
W = (75) (10) (0)
W = 0 J
Answer:
Solution:
As per the question:
Initial frequency of the processor, f = 2.5 GHz =
Final frequency attained by the processor, f' =
Initial dynamic power,
Leakage Power,
Now,
To calculate the Dynamic power, and leakage power consumed by the processor:
We know that the dynamic power is in direct proportion to the frequency of the processor:
∝ frequency, f
Thus we can write:
Substituting the appropriate values in the above expression:
Now,
We know that the leakage power does not depend on the frequency of the processor and hence remains same.
Thus
Answer:
Cu + Br2 = CuBr2
Explanation:
Written above is the balanced version of the equation. It is a synthesis reaction.
Speed is a scalar quantity, meaning it has no direction. Velocity is a vector, meaning that it has a specific direction associated with it.
Many people use these interchangeably, but it is not always correct to do so.
Answer:
The question implies that force of friction is 2.1E4 N
F = M v^2 / R frictional force needed to supply this centripetal force
2.1E4 = M v^2 / R
v^2 = R * 2.1E4 / M
v^2 = 120 * 2.1E4 / 2.5E3 = 1200 * 2.1 / 2.5 = 1008 m^2/s^2
v = 31.7 m/s max speed of truck (about 70 MPH)
