A horizontal circular wire loop of radius 0.7 m lies in a plane perpendicular to a uniform magnetic field that is pointing down
Maru [420]

Answer:

\epsilon=1.10\ V

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,

A_1=\pi r^2

A_1=\pi (0.7)^2=1.539\ m^2

For the area of square,

The circumference of wire, C=2\pi r=2\pi \times 0.7=4.39\ m

Side of square, l=\dfrac{4.39}{4}=1.09\ m

Area of square, A_2=1.09^2=1.188\ m^2

An emf is induced in the loop due to change in its area. The induced emf is given by :

\epsilon=-B\dfrac{dA}{dt}

\epsilon=-B\dfrac{A_2-A_1}{t}

\epsilon=-0.44\times \dfrac{1.188-1.539}{0.14}  

\epsilon=1.10\ V

So, the magnitude of the average induced emf is 1.10 volts. Hence, this is the required solution.

A rock, with a density of 3.55 g/cm^3 and a volume of 470 cm^3, is thrown in a lake. a) What is the weight of the rock out of th
SIZIF [17.4K]

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

   \texttt{Buoyancy force}= \frac{470\times 1\times 9.81}{1000} = 4.61 N

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

You apply a net force on a soccer ball of 15 N. If the acceleration it has is 5 m/s2 what is the mass of the ball?​
Ipatiy [6.2K]

Answer:

<h2>3 kg </h2>

Explanation:

The mass of the ball can be found by using the formula

m =  \frac{f}{a}  \\

f is the force

a is the acceleration

We have

m =  \frac{15}{5}  = 3 \\

We have the final answer as

<h3>3 kg</h3>

Hope this helps you

Explain the statement: “Cells are the basic units of structure and function in living things.”
babymother [125]

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.
