Answer: 16.22 m/s^2
Explanation: g= GM/r^2 G= (6.67x 10^-11) M= 1.66(6x 10^24) r=(6400x 10^3) so
((6.67x10^-11)(1.66x 6x 10^24))/ (6400x10^3)^2 = 16.22 m/s^2
Answer: 30
Explanation: it is 30 meters per seconds
Energy is (transferred) when it is moved from one obect to another.
The answer is (b)
Answer:
C Restoring Force
Explanation:
Given data
Fs=-kx
According to Hokes Law, provided the elasticity of an elastic material is not exceeded the extension xis directly proportion to the applied force F
From the expression, F represent the Restoring Force in Newton
