D. Gravitational Force
because if the object is heavy and it is higher above the ground the more gravitational energy it holds it increases as weight and height increases
Answer:
Following are the solution to the given question:
Explanation:
For crashing speed, we can use energy conservation:
kinetic energy
potential energy
moon mass
Radius
Calculating the mass drop for the leave:
Solve the value for
The approach is correct but misrepresented in replacing 180 km instead of 110 km.
Answer:
The capacitance is 1.75 nF
Explanation:
From the question we are given that
The inner radius is
The outer radius is 000.1
Length of the capacitor is L = 1m
The dielectric constant is Di = 2
The dielectric constant is Di2 = 4
Generally the capacitance of a capacitor can be mathematically represented as
1.75nF
Answer:
a. The speed is 2.39 m/s
b. The acceleration of the block is 10.2
Explanation:
First, we have to do the energy balance where we consider two states, the first where the spring remains still and the second when it is stretched 0.400m:
Δx=
W_{ext}=20.4 Nm
To determine, the acceleration we solve the following equation for a:
