V= 1/3 π r²h
this is the formula for a cone hope this helps :)
It's not in motion when the line straight and flat . there's #9
Answer:
momentum=mass x velocity= 10 x 2 = 20kgm/s
We know, U = m * g * h
U = 4000 * 9.8 * 20
U = 784000 J
In short, Your Answer would be: 784000 J or 784 KJ
Hope this helps!
Hello!
A portable DVD player requires six 1.5-volt batteries to operate. If the resistance in the circuit is 7.2 ohms, what is the current?
Data:
We have six 1.5 volt batteries, soon, your tension (V)
V = 1.5 * 6 = 9 Volts
R (resistance) = 7.2 ohms
I (Current intensity) = ? (in Amps)
Solving (Ohm's First Law):



Answer:
The current is 1.25 amps
