Answer:
Explanation:
The acceleration due to gravity on the surface of the Earth is given by:
where
G is the gravitational constant
M is the mass of the Earth
R is the radius of the Earth
Here we want to find the new Earth radius R' for which the gravitational acceleration at the surface, g', would be 3 times the current value of g:
So we would have
Solving the equation for R', we find
Answer:
Acceleration of the proton will be equal to
Explanation:
We have given electric field
Mass of proton is equal to
And charge on proton is equal to
Electrostatic force will be responsible for the motion of proton
Electrostatic force will be equal to
According to newton law force on the proton will be equal to F = ma, here m is mass of proton and a is acceleration
This newton force will be equal to electrostatic force
So
So acceleration of the proton will be equal to
Hello!
Using Hooke's law, F spring=k delta x, find the distance a spring with an elastic constant of 4 N/cm will stretch if a 2 newton force is applied to it.
Data:
Hooke represented mathematically his theory with the equation:
F = K * Δx
On what:
F (elastic force) = 2 N
K (elastic constant) = 4 N/cm
Δx (deformation or elongation of the elastic medium or distance from a spring) = ?
Solving:
simplify by 2
Answer:
B.) 1/2 cm
