Atoaster with a power rating of 1,000 watts is plugged into a household voltage of 120 volts. how much current runs through the toaster?
a) 120,000 amps
b) 880 amps
c) 8.3 amps
d) 0.120 amps

Answer : I = 8.33 A

Explanation :

It is given that,

Power rating of the toaster, P = 1000 watts

Household voltage, V = 120 volts

We know the relation between power, voltage and the current is :

8.33 A of current runs through the toaster.

Hence, this is the required solution.

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
