The answer would be C. Gamma Rays and High Frequency EM waves travel at the speed of light and are transverse waves.
Answer:
5.82812 rad/s
Explanation:
L = Length of meter stick = 1 m = 100 cm
= The center of mass of the stick = 
= Angular velocity
Moment of inertia of the system is given by
As the energy in the system is conserved
The maximum angular velocity is 5.82812 rad/s
Answer:
false
Explanation:
every object will always have the force of gravity acting upon it.
Answer:
2 amps
Explanation:
Given data
Power = 460W
voltage= 230V
Required
The amperage/ current of the fuse
Recall P= IV
I= P/V
I= 460/230
I=2 amps
Hence the current of the fuse is 2 amps
Answer:
Workdone = 20 Joules
Explanation:
Given the following data;
Force = 10N
Extension, e = 4cm to meters = 4/100 = 0.04 meters
Workdone extension = 40cm to meters = 40/100 = 0.4 meters
To find the work done;
First of all, we would find the spring constant using the formula;
Force = spring constant * extension
10 = spring constant * 0.04
Spring constant = 10/0.04
Spring constant = 250 N/m
Next, we find the work done;
Workdone = ½ke²
Where;
k is the spring constant.
e is the extension.
Substituting into the formula, we have;
Workdone = ½ * 250 * 0.4²
Workdone = 125 * 0.16
Workdone = 20 Joules
