The power supplied to a typical black-and-white television set is 90 w when the set is connected to 120 v. (a) how much electrical energy does this set consume in 1 hour? (b) a color television set draws about 2.5 a when connected to 120 v. how much time is required for it to consume the same energy as the black-andwhite model consumes in 1 hour?

The electrical energy and time required for it to consume the same energy are and 18 min.

Explanation:

Given that,

Power = 90 W

Voltage V = 120 V

Current = 2.5

(a). We need to calculate the  amount of energy

Using formula of energy

Where, p = power

t = time

Put the value into the formula

(b). We need to calculate the  power

Using formula of power

Where, I = current

V = voltage

Put the value into the formula

We need to calculate the time

Using formula of time

Put the value into the formula

Hence, The electrical energy and time required for it to consume the same energy are and 18 min.

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.

- to persuade the parliament that merely since she has a child does not assure that the kid will be a capable leader.

- to sway the parliament how shattering it could be if they proceeded discourteously concerning her or her child.
