Answer:
What is the centripetal acceleration of the tip of the fan blade?
6.0 m/s2
48 m/s2
53 m/s2
96 m/s2
Answer is 96
Explanation:
72s for 24 complete oscillations.
Thus, a complete oscillation takes 72/24=3s
Answer: period T=3s
Answer:5.17 m/s
Explanation:
Given
let u be the speed at cliff initial point
range over cliff is 1.45 m
and range of projectile is given by


u=3.77 m/s
Conserving Energy

Kinetic energy=Kinetic energy +Potential energy gained
Let v be the initial velocity





Remain the same
Explanation:
If the force exerted by the intern is doubled and the distance is halved, the work done by the intern remains the same.
Work done is the force applied to move a body through a distance.
Work done = F x d
where F is the applied force
d is the distance moved
Now;
if:
f = 2f
d =
d
Input the parameter:
Work done = fxd = 2f x
d = fd
The work done will still remain the same

In order for two vectors to add to zero, they must have the same magnitude and point in opposite directions.
Two perpendicular vectors, by definition, make a right angle with each other whereas two vectors pointing in opposite directions form a straight line.
Because of this, two perpendicular vectors with nonzero magnitudes will never add to zero.
