Answer:
The equation of motion is 
Explanation:
The general equation of motion of a SHM motion is given by
where,
A is the amplitude of the motion
ω is the natural frequency of the system
Since amplitude is defines as the maximum displacement of the object from the mean position we have
Now the time period is related to the natural angular frequency as
Thus the equation of motion becomes
the initial phase can be assumed to be zero thus the equation becomes
Answer:
1.67m/s
Explanation:
Total Distance to be travelled by a Runner=100m
Time Taken=10*6s
Speed=Distance/Time
=100/10*6=10/6=1.67m/s
Answer and Explanation:
(a) The attached image below shows the diagram of a CRT in the helmholtz coils and well labelled with details
(b). The electron will follow a circular path which travels along under constant magnetic field
where m = mass of electron, V = velocity of electron, q = charge of the electron and B = magnetic field strength
If the force and the motion are along the same direction (like it is here) then work is force*distance. The time doesn't come into play until you want the power used. So here
W=9.0*3.0=27J
The kinetic energy (KE) is 250 J and the gravitational potential energy (GPE) is 392 J
