Parallel 33. A 4-watt night light is plugged into a 120-volt
circuit and operates continuously for a 30-day
month.
a. How much current does it draw?
b. What is the resistance of its filament?
c. How much energy does it use in the month?
d. What is the cost of its operation for the
month at the utility rate of 10 cents per
Kilowatt-hour?

that would be because of both gravity and friction. so     c

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.

4.            a) parents who reason openly with children can limit a child’s cognitive ability.
