The mass of a water skier is 54 kg. Calculate his/her weight if the gravitational field strength is 10 N/kg.

weight=mass×gravity

the mass in this question is 54kg and the gravity is 10

therefore:

w=54×10

=540N

I hope this helps

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27
