Answer:
Explanation:
The equation of force is
F = 4 sin 4 t
Compare with the standard equation
f = A sin wt
where, w is the angular frequency and A is the amplitude.
Now
w = 4 rad/s
Let the time period is T.
the relation for the time period is
the time period is defined as the time taken by the body to complete one oscillation.
So, the velocity is zero at the extreme points where the object is at time, T/4 and its odd T/2, 3T/4, 3T/2, etc.
So, the velocity is zero at time
Final answer:
To determine the position of the mass and the times when the velocity is zero in a mass-spring system.
Explanation:
To determine the position of the mass at any time, we need to solve the equation of motion for the mass-spring system. The equation is:
mx'' + kx = Fext
where m is the mass, x is the displacement of the mass from its equilibrium position, k is the spring constant, and Fext is the external force. We can solve this differential equation to find the position of the mass as a function of time.
To determine the first four times at which the velocity of the mass is zero, we need to solve for the velocity of the mass, which is given by:
v = x'
We can find the times at which the velocity is zero by finding the values of t for which x' = 0.

Answer: The correct answer is option (D).
Explanation:
Voltmeter is a device which measures the the voltage applied across the circuit. It is an electrical instrument used to measure the electric potential between the two points in an electric circuit.
Where as:
A switch is the device which used to connect or disconnect the circuit.
Resistor is a device which opposes the flow of current is an electric circuit.
An ammeter the is an electrical device which measures the amount of current in flowing in amperes in an electrical circuit
Hence,the correct answer is option (D).

Okay so we need to bring a couple of equations into this
First E =F/q
We have our q and E lets solve for F
F = Eq
So remember th equation
F = qV x B
F = qVBsin(Ф)
The angle is perpendicular so
sin(90) = 1
F = qVB
Solve for V
F/qB = V
Eq/qB = V
Look at that the charges cancel out!
V = E/B
(Fun fact: Thats what they use in mass spectrometers which is why it says the particle should travel in a straight line)
Anyways lets solve this!
V = 2/5
V = 0.4 m/s
there are 2 forces acting on the particle: magnetic n electric force
the 2 forces must be equal 4 it to travel in a straight line
as it has +1C charge, q, the charge is dropped in the following:
magnetic force = qv x B where v is velocity n B is magnetic field;
x represents cross-product which in this case of 90-deg. is same as multiply
magnet force = v*5
electric force = qE where E is electric field
= 2
as magnet force = electric force
v*5 = 2
v=2/5=0.400m/s
