Answer:
2.7 mV
Explanation:
A = 3.6 x 10^-3 m^2
B1 = 0.20 T, B2 = 1.4 T, t = 1.6 s
According to the Faraday's law of electromagnetic induction
e = - rate of change of magnetic flux
e = - dФ / dt
where, negative sign shows the direction of induced emf.
Ф = B x A
dФ / dt = A x dB / dt
e = A x dB / dt = 3.6 x 10^-3 x (1.4 - 0.2) / 1.6
e = 2.7 x 10^-3 V = 2.7 mV
Answer:
The distance of separation is
Explanation:
From the question we are told that
The wavelength is
The distance of the screen is
The distance between the fringes is
Generally the distance between the fringes is mathematically represented as
Here d is the distance of separation between the slit

Given :
A box weighing 12,000 N is parked on a 36° slope.
To Find :
What will be the component of the weight parallel to the plane that balances friction.
Solution :
The component of that will be parallel to the plane to balance friction is :
Therefore, component of force to balance friction is F sin 36° .
Hence, this is the required solution.
Answer:
acceleration =9.2089
Explanation:
force acting: gravity, normal force exerted by the box
F=m*a
= 25*g
=25*gcos(20)
= 230.224N
acceleration= gcos(20)
= 9.8*0.939
acceleration =9.2089
