The acceleration due to gravity on Jupiter is 24.79 m/s²,
compared to 9.8 m/s² on Earth ... a ratio of about 2.53 .
So if a person or object were somehow transported to Jupiter,
he/it would weigh
(2.53) times (Earth weight)
there.
Answer:
change in gravitational potential energy Δ PE = 392 J
Explanation:
given data
mass of the person m = 80 kg
height of the centre of mass Δh = 0.50 m
to find out
change in gravitational potential energy
solution
we get here change in gravitational potential energy that is express here as
change in gravitational potential energy Δ PE = m × g × Δh .........1
put here value we get
change in gravitational potential energy Δ PE = m × g × Δh
change in gravitational potential energy Δ PE = 80 × 9.8 × 0.50
change in gravitational potential energy Δ PE = 392 J
Answer:
a. 150 N
Explanation:
Gravitational Force: This is the force that act on a body under gravity.
The gravitational force always attract every object on or near the earth's surface. The earth therefore, exerts an attractive force on every object on or near it.
The S.I unit of gravitational force is Newton(N).
Mathematically, gravitational force of attraction is expressed as
(i) F = GmM/r² ........................ Equation 1 ( when it involves two object of different masses on the earth)
(ii) F = mg ............................... Equation 2 ( when it involves one mass and the gravitational field).
Given: m = 17 kg, g = 8.8 m/s²
Substituting into equation 2,
F = 17(8.8)
F = 149.6 N
F ≈ 150 N.
Thus the gravitational force = 150 N
The correct option is a. 150 N
Answer:
0.5504
Explanation:
We can use Bay's theorem to solve this question
P( No physics career/fail) = P(No Physics career and fail)/P(Fail)
= P( Fail/ No physics career)×P( no physics career)/P( fail)
=
=0.5504
