Answer:
The induced current is 
Explanation:
From the question we are told that
The number of turns is
The cross-sectional area is 
The initial magnetic field is 
The magnetic field at time = 1.02 s is 
The resistance is 
The induced emf is mathematically represented as

The negative sign tells us that the induced emf is moving opposite to the change in magnetic flux
Here
is the change in magnetic flux which is mathematically represented as

Where dB is the change in magnetic field which is mathematically represented as

substituting values


Thus


So


The induced current i mathematically represented as

substituting values


Answer with Explanation:
We are given that


We have to find the direction and magnitude of the third force acting on the object.
Resultant force,F=

The object moves with constant velocity .Therefore, net force on object is equal to zero
So,Third force,
Direction,

Angle lies in second quadrant because the direction of third force is opposite to the direction of the resultant force of F1 and F2.
Therefore,
When a simple machine multiplies force, it decreases (B) Distance moved, force is described as an interaction, which, unopposed, will change the motion of an object, the potential energy, however, remains the same.
Answer:
17.3 m
Explanation:
Given that,
Mass of a hammer is 0.58 kg
Velocity with which the hammer slides is 6.69 m/s at constant speed.
The roof makes an angle of 18 ◦ with the horizontal, and its lowest point is 18.2 m from the ground. We need to find the horizontal distance traveled by the hammer between the time is leaves the roof of the house and the time it hits the ground. Firstly, we will find the time taken by the hammer when it reaches ground in vertical direction.

Putting all the values,

Neglecting negative value,
To find horizontal distance, multiply 2.72 s with the horizontal component of velocity.

Answer:
the impedance of the circuit is 25.7 ohms.
Explanation:
It is given that,
Voltage, V = 50 volts
Frequency, f = 60 Hz
Resistance, R = 25 ohms
Capacitive resistance, 
Inductive resistance, 
We need to find the impedance of the circuit. It is given by :


Z = 25.7 ohms
So, the impedance of the circuit is 25.7 ohms. Hence, this is the required solution.
