Your right. It's C. This question is difficult
Answer:
Explained
Explanation:
The cheater pipe extends the wrench in radial direction, providing a larger momentum for the force you exert.
For a given force the torque exerted with the cheater pipe is larger.
Mathematically we can write that
τ = r×F and τ'= r'×F
now since r'> r
⇒ F'>F
Answer:
The ratio of their orbital speeds are 5:4.
Explanation:
Given that,
Mass of A = 5 m
Mass of B = 7 m
Radius of A = 4 r
Radius of B = 7 r
The orbital speed of satellite A,
......(I)
The orbital speed of satellite B,
......(I)
We need to calculate the ratio of their orbital speeds
Using equation (I) and (II)

Put the value into the formula


Hence, The ratio of their orbital speeds are 5:4.
