Hello:)!<br> I don’t really understand the uniform deceleration too :/
NARA [144]

Answer:

Deceleration is the opposite of acceleration.

The mathematical formula for deceleration is:

Deceleration = \frac{Final velocity - Initial velocity}{Time taken}

Uniform deceleration of an object can be defined as  decreasing the velocity of an object in equal amount in an equal interval of time.

The graph attached below shows a constant decrease in the velocity with a uniform time interval.

Which of the following is a vector quantity?
djverab [1.8K]

Vector quantity is defined by direction as well as magnitude both

so now lets discuss all option

1) distance = it is total path length between two points so there is no direction needed in it so it is scalar

2) Speed = it is ratio of total distance covered and total time, so it also do not require any direction.

<em>3)velocity = it is ratio of displacement and time, and displacement is always given with direction so velocity is a vector quantity</em>

4) time = time is the measurement of the interval of two events and we do not require any direction in it so its a scalar quantity.

Q.01 When charging a secondary cell, energy is stored within a dielectric material using an electric field. True or False
Nitella [24]

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.
