Q.01 When charging a secondary cell, energy is stored within a dielectric material using an electric field. True or False

Physics
1 answer:
Nitella [24]3 years ago

True, when charging a secondary cell, energy can be stored within a dielectric material using an electric field.

<h3>Relationship between dielectric material and electric field</h3>

The electric field in a capacitor separates the negative and positive charges in the dielectric material, this causes an attractive force between each plate and the dielectric.

The dielectric material can store electric energy due to its polarization in the presence of external electric field, which causes the positive charge to store on one electrode and negative charge on the other.

Thus, when charging a secondary cell, energy can be stored within a dielectric material using an electric field.

Three deer, a, b, and c, are grazing in a field. deer b is located 62.1 m from deer a at an angle of 54.3 ° north of west. deer
sveticcg [70]

by cosine law we know that

c^2 = a^2 + b^2 - 2 abcos\theta

\theta = 180 - 54.3 - 79.1 = 46.6 degree

now using above equation

93.8^2 = 62.1^2 + b^2 - 2*62.1*b * cos46.6

4942.03 = b^2 - 85.34 b

b^2 - 85.34b - 4942.03 = 0

by solving above quadratic equation we have

b = 124.9 m

so it is at distance 124.9 m from deer a

If the sun's mass is about average, how many stars are there in the milky way galaxy? the mass of the sun is of the order of 103
ra1l [238]
Just assume that the sun has the average mass of all the stars
Then divide the mass of the galaxy by the mass of the sun. 
<span>10^30 has 30 zeroes after it. 10^42 has 42 zeroes.

The answer would have 12 zeroes which concludes a trillion stars. </span>

Elaine and her bike have a combined mass of 50 kg. in a bicycle race, Elaine uses the pedals to create a forward force of 75 N.
yarga [219]
If the friction and air resistance was 75N and Elaine was traveling with a force of 75N the forces would cancel out. Elaine's bike would not be moving and all the forces would be balanced
