Answer:
67.5
Explanation:
The plane accelerates at 2.7m/s,^2
Time is 25 seconds
The velocity can be calculated as follows
= 25×2.7
= 67.5
Hence the speed f the plane is 67.5
Answer:
The laptop battery is capable of supplying 253980 J.
Explanation:
Given;
voltage of the battery, V = 11.4 V
power consumed by the laptop, P = 8.3 W
duration of the battery before depletion, t = 8.5 hours
Determine the amount of energy supplied by the laptop battery within 8.5 hours.
Energy, E = Power x time
Energy, E = 8.3 W x 8.5 h = 70.55 Wh
Energy, E in joules = 70.55 wh x 3600 s/h = 253980 J
Therefore, the amount of energy supplied by the laptop battery within 8.5 hours is 253980 J.
