Answer:
0.02 m
Explanation:
R₁ = initial distance jumped by jumper = 7.4 m
R₂ = final distance jumped by jumper = ?
θ₁ = initial angle of jump = 45°
θ₂ = final angle of jump = 42.9°
= speed at which jumper jumps at all time
initial distance jumped is given as
final distance jumped is given as
Dividing final distance by initial distance
distance lost is given as
d = 
d = 7.4 - 7.38
d = 0.02 m

Answer:
The electricity cost of this refrigerator per month (30 days) = $7.488
Explanation:
Amount of power consumed by the refrigerator while running = 320 W
The refrigerator runs one-quarter of the time,
So, for 30 days, 30 × 24 hours, 720 hours,
The refrigerator uses 320 × 720 × (1/4) W.h = 57600 W.h = 57.6 KWh
And electricity costs, $0.13 per KWh,
That is, 1 KWh = $0.13
57.6 KWh = 57.6 × 0.13 = $7.488
