Answer:

Explanation:
It is given that,
Radius of the circular loop, r = 0.7 m
Magnetic field, B = 0.44 T
In 0.14 s the wire is reshaped from a circle into a square, but remains in the same plane.
Area of the circular wire,


For the area of square,
The circumference of wire, 
Side of square, 
Area of square, 
An emf is induced in the loop due to change in its area. The induced emf is given by :



So, the magnitude of the average induced emf is 1.10 volts. Hence, this is the required solution.
Answer:
a) Weight of the rock out of the water = 16.37 N
b) Buoyancy force = 4.61 N
c) Mass of the water displaced = 0.47 kg
d) Weight of rock under water = 11.76 N
Explanation:
a) Mass of the rock out of the water = Volume x Density
Volume = 470 cm³
Density = 3.55 g/cm³
Mass = 470 x 3.55 = 1668.5 g = 1.6685 kg
Weight of the rock out of the water = 1.6685 x 9.81 = 16.37 N
b) Buoyancy force = Volume x Density of liquid x Acceleration due to gravity.
Volume = 470 cm³
Density of liquid = 1 g/cm³

c) Mass of the water displaced = Volume of body x Density of liquid
Mass of the water displaced = 470 x 1 = 470 g = 0.47 kg
d) Weight of rock under water = Weight of the rock out of the water - Buoyancy force
Weight of rock under water = 16.37 - 4.61 =11.76 N
Answer:
Explanation:
a) because it's immoral as you're trying to convince people of your views when you should be giving both sides of the story so people are able to come up with their own opinions on what you're talking about
Answer:
<h2>3 kg </h2>
Explanation:
The mass of the ball can be found by using the formula

f is the force
a is the acceleration
We have

We have the final answer as
<h3>3 kg</h3>

All living things are made up of cells. Each cell's individual function helps the organism collectively function. They are the most basic as they can be self-contained. And there is no other particle smaller that can function on it's own.
