Correct option is B
1 kWh is equal to 3.6 × 10
6

1 Watt-sec is a Joule a watt expended for a second.
Because there’s 3600 seconds in an hour,
then 3600 Ws = 1 Wh = 3600 Joules = 3.6 kJ
so 1000 Wh = 1 kWh = 1000 × 3.6 kJ = 3.6 MJ = 3.6 × 10

A man pushes a lawn mower on a level lawn with a force of 195 N. If 37% of this force is directed downward, how much work is don
densk [106]

Answer:

W = 1032.6 J

Explanation:

Net force by which man push the lawn mower is given as

F = 195 N

now it is given that 37% of this force is vertically downwards

so we will have

F_y = 0.37 \times 195

F_y = 72.15 N

now we also know that

F_x^2 + F_y^2 = F^2

here we have

F_x^2 + 72.15^2 = 195^2

F_x = 181.2 N

Now work done by this force to move the lawn mower is given as

W = F_x . d

W = (181.2)(5.7 m)

W = 1032.6 J

Suppose you are in an elevator. As the elevator starts upward, its speed will increase. During this time when the elevator is mo
kkurt [141]

Answer:increased

Explanation:

It is given that elevator speed is increasing while moving upward i.e.its acceleration is increasing .

This causes the apparent to be increased if measured using weighing machine.

considering upward direction to be positive

N-mg=ma

N=m(g+a)

where N=Normal reaction=Apparent weight

a=acceleration of Elevator

thus you feel as if your weight is increased.
