Answer:
Explanation:
Simply put, because weight is a kind of Force.
Answer:
8.95 m/s
Explanation:
(3.5-1.0) x 2 = gt²
t = √5/9.8 = 0.714 sec
= X/t = 4/ 0.714 = 5.602 m/s
vertical velocity means it has to rise 1.0 m against gravity in 0.714s
= gt = 9.8 x 0.714 = 6.99 m/s
V = √²+ ² = √6.99²+5.602² = 8.95 m/s
Answer:
terminal voltage = 1.34 V
power = 2.68 W
Explanation:
given data
voltage E = 1.54 V
current = 2A
internal resistance = 0.100 ohm
to find out
terminal voltage and electrical power
solution
we know terminal voltage formula is
terminal voltage = E - current × resistance
terminal voltage = 1.54 - ( 2 × 100 )
terminal voltage = 1.34 V
and
power is calculated by ohm law
Power = V × current
power = 1.34 × 2
power = 2.68 W
