With "toward the wall" designated as the positive direction, the average acceleration felt the ball in the 0.0158 s of contact with the wall is

Answer:
Explanation:
Force constant of spring K = 21 N /m
we shall find the common velocity of putty-block system from law of conservation of momentum .
Initial momentum of putty
= 5.3 x 10⁻² x 8.97
= 47.54 x 10⁻² kg m/s
If common velocity after collision be V
47.54 x 10⁻² = ( 5.3x 10⁻² + .454) x V
V = .937 m/s
If x be compression on hitting the putty
1/2 k x² = 1/2 m V²
21 x² = ( 5.3x 10⁻² + .454) x .937²
x² = .0212
x = .1456 m
14.56 cm
I think that the answer is yes. Because copper is a cunductor of DC and AC. However electritions are trying to avoid copper wiring because its a poor conductor.
So I guess you could goth ways but I say yes it could work.
The density of a cube that has a mass of 12. 6 and a measured length of 4.1 cm is 0.18 kg/cm³
Density=mass/volume
mass=12.6
volume=68.9
density=12.6/68.9
density=0.18 kg/cm³
Density is defined as a material substance's mass per unit volume. Density is described by the equation d = M/V, where d stands for density, M for mass, and V for volume. Grams per cubic centimeter is the unit of measurement for density. For instance, compared to Earth's density of 5.51 grams, water has a density of 1 grams per cubic centimeter . Another way to express density is in kilograms per cubic meter (in meter-kilogram-second or SI units), It is easy to determine the relationship between mass and volume using density. For instance, the formula for determining a body's mass is M = Vd, while the formula for determining a body's volume is V = M/d.

Answer:
The rate of current change in the circuit is 
Explanation:
From the question we are told that
The capacitor has a value 
The inductor has a value 
The capacitors voltage is
at t = 0s
The new capacitor voltage is 
Generally when the switch is closed the potential across the inductor is equal to the potential across the capacitor
So for the inductor
rate of current change is given as

Where
is the voltage across the inductor. 
Substituting value
