Answer:
1.1215 h
Explanation:
Δt=Δt_o/√(1-u^2/c^2)
(Δt° is the proper time in the rest frame,
Δt is the time intent measured in the second frame of reference u is the speed of the second frame with respect to the rest frame c is the speed of light )
a) the proper time is the time on spacecraft (rest frame);
Δt = 365 days = 8760 h
Δt=Δt_o/√(1-u^2/c^2)= 8761.1215 h
the difference = 8761.1215 h — 8760 h = 1.1215 h
The electric field strength will be 0.6252 V/m. It is the strength at which the field is created by charges.
<h3>What is electric file strength?</h3>
The electric field strength is defined as the ratio of electric force and charge.
The electric field strength is found as;
Hence, the electric field strength will be 0.6252 V/m.

Answer:
The universal law of gravitation.
PE = m * G M / R^2 potential energy of mass m due to attractive forces
If the kinetic energy of mass m is greater than the energy due to the attractive masses then then mass m can continue indefinitely away from the attracting masses.
The rock it traveling really, really fast.
It is hard to exactly determine how fast bc u need the height of the cliff and how big the rock is.
Hope this helps and can I get brainliest answer!
