I = Delta p
I = Impulse
Delta p = Momentum variation
Delta p = pf - po
Pf = Final momentum
Po = Initial momentum
p = m x v
M = Mass
V = Velocity
Delta p = (m x Vf) - (m x Vo)
I = 1.2 x 10^3 x 20 - 12 x 10^2 x 18
I = 2.4 x 10^4 - 216 x 10^2
I = 2.4 x 10^4 - 2.16 x 10^4
I = 0.24 x 10^4
I = 24 x 10^2 Newtons x seconds (N x s)
Answer: The value of impulse is 24 x 10^2 Newtons x seconds (N x s).
when you drop a ball and let it fall to the ground
Answer: it is rocket 2
Explanation: I just took the test
Hope it's the right answer for you
If someone upsets you ,it is your responsibility to make changes so that they don't do it again.
The statement is true.
As by making changes you don't give them any chances of repeating that thing.
HOPE IT HELPS!!!!
PLEASE MARK BRAINLIEST!!!!
Power (rate of using energy) = (voltage) x (current)
Power of this heating element = (120 V) x (3.2 A) = 384 watts
The easy way:
384 watts = 0.384 kilowatt
(0.384 kilowatt) x (5 hours) = 1.92 kilowatt-hour
Another way:
384 watts = 384 joules per second .
(384 joule/sec) x (3600 sec/hour) x (5 hours)
= (384 x 3600 x 5) (joules) = 6,912,000 joules.
