4) A steel tape is placed around the earth at the equator when the temperature is 0 C. What will the clearance between the tape and the ground (assumed to be uniform) be if the temperature of the tape rises to 30 C. Neglect the expansion of the earth (the radius of the earth is 6.37 X 106 m)
1 answer:
Answer:
2102.1 m
Explanation:
Temperature at the equator = 0⁰
Radius of the earth = 6.37x10⁶
Required:
We how to find out what the clearance between tape and ground would be if temperature increases to 30 degrees.
Final temperature = ∆T = 303-273 = 30
S = 11x10^-6
The clearance R = Ro*S*∆T
=6.37x10⁶x 11x10^-6x30
= 2102.1m
Or 2.102 kilometers

Answer:
N=945.76 RPM
Explanation:
Given that
A= 0.15 m
Acceleration = 0.6 g
a=0.6 x 9.81 m/s²
a= 5.886 m/s²
We know that acceleration a given as
a = ω² A
ω=Angular speed
ω=99.04 rad/s
We know that
N=945.76 RPM
Therefore the speed of the motor will be 945.76 RPM.
