Answer:
0.0814 Wb
Explanation:
L = length of the rectangular coil = 5 cm = 0.05 m
w = width of rectangular coil = 7 cm = 0.07 m
A = Area of the coil = L w = 0.05 x 0.07 = 35 x 10⁻⁴ m²
B = magnitude of uniform magnetic field = 0.55 T
θ = angle of axis of coil with magnetic field = 65°
Magnetic flux through the coil is given as
Φ = N B A Cosθ
Φ = (100) (0.55) (35 x 10⁻⁴ ) Cos65
Φ = 0.0814 Wb
Answer:
125.5J
Explanation:
Given parameters:
Mass of the bowling ball = 6.1kg
Height of lifting = 2.1m
Unknown:
Increase in the ball energy = ?
Solution:
The ball has changed position by moving it from one point to another. So, it has acquired more potential energy.
Potential energy = mgh
m is the mass
g is the gravity
h is the height
Now insert the given parameters and solve;
Potential energy = 6.1 x 9.8 x 2.1 = 125.5J

The first force is 
The acceleration by which the cart moves to the right is 
The mass of the cart is m = 3.231 kg
Generally the net force on the cart is

This net force is mathematically represented as

So



Answer:
no it gets it form the sun
Explanation:
Answer:
1.5T
Explanation:
Since, the amplitude of SHM is A. So, in one time period T the object will travel travel a distance of 4A.
6A-4A= 2A.
Now, this 2A distance must be traveled in T/2 time period.
So, the total time taken to travel a distance of 6A is T+T/2 = 3T/2 = 1.5T
