Velocity = distance / time
v = (15*1000)m / (2*60*60)s
v=2.08 m / s
Answer: 0.09 m
Explanation:
Centripetal acceleration in terms of tangential speed is:
where r is the radius.
It is given that,
centripetal acceleration of the mouse, 
tangential speed , 
Radius of salami is:
Thus, the radius of the salami is 0.09 m.
Answer: 0.0180701 s
Explanation:
Given the following :
Length of string (L) = 10 m
Weight of string (W) = 0.32 N
Weight attached to lower end = 1kN = 1×10^3
Using the relation:
Time (t) = √ (weight of string * Length) / weight attached to lower end * acceleration due to gravity
g = acceleration due to gravity = 9.8m/s^2
Weight of string = 0.32N
Time(t) = √ (0.32 * 10) / [(1*10^3) * (9.8)]
Time = √3.2 / 9800
= √0.0003265
= 0.0180701s
