Answer:
if the resistor is fitted in series with the bulb , then the current flowing will be 0.15 A.....
if the resistor if fitted in parallel with the bulb ,
the current flowing will be 0.6 A
Explanation:
total potential difference = 1.5V
when resistors in series ,
total equivalent resistance is = 5 + 5 = 10 ohm
so current = 1.5 ÷ 10 = 0.15
when resistors in parallel ,
total equivalent resistance is = (5 × 5)÷(5 + 5) =2.5 ohm
so current = 1.5÷2.5 = 0.6 A
Answer:
306.12N/m^2
Explanation:
Mass = 30 kg
g = 9.8m/s2
F = mg
F = 30 x 9.8
F = 294N
L = 0.98m
Since the stilts is square, then the area is L^2
A = L^2
A = 0.98^2
A = 0.9604m^2
P =?
P = F/A
P = 294/0.9604
P = 306.12N/m^2
The pressure exerted by the man is 306.12N/m^2
Power is the rate that work is done or work per unit time.
So doing more work per unit time creates more power.
Power = Work / time
exosphere is the outer layer of the atmosphere
