(5 bulbs) x (25 watt/bulb) x (6 hour/day) x (30 day/month) =

             (5 x 25 x 6 x 30) watt-hour/month =

                 22,500 watt-hour/month .

The most common unit of electrical energy used for billing purposes
is the 'kilowatt-hour' = 1,000 watt-hours .

               22,500 watt-hour/month =  <em>22.5 kWh/month</em>.

             (22.5 kWh/month) x (1.50 Rs/kWh) =  <em>33.75 Rs / month

a toy dart gun generates a dart with .140kg.m/s momentum and a velocity of 4m/s. what is the mass of the dart in grams?
sleet_krkn [62]

Answer: m = 0.035kg = 35g

Explanation: Momentum p=0.140kgm/s

Velocity v=4m/s

Mass m=?

Formula-

Momentum depends on the mass of the object in motion and its velocity.

The equation for momentum is

p = mv

m = p/v

m = 0.140/4

m = 0.035kg

m = 35g

Hence, in the toy dart gun mass of the dart is 0.035kg.
