Answer:
5290 W
Explanation:
Resistance of the drier in 1440W, 120V setting
= V² / W
= 120 x120 / 1440
= 10 ohm
Resistance of the drier in 1440W, 230V setting
= 230 x 230 / 1440
= 36.736 ohm
Now drier of 1440W, 120V setting
used in 230V
Power used by it
= V² / R
= 230 X 230 / 10
= 5290 W
Answer:
Land heats faster
Explanation:
Land heats faster because absorbs much more solar radiation.
Distance= Time×Speed
= 1800×1.5
= 2700 m
I am not sure it's right. the question itself is confusing.
Answer:
Acceleration
Explanation:
Momentum is acceleration because acceleration is movement and momentum is movement.
Momentun = Movement
Acceleration = Movement
Momentum = Acceleration
