Answer: Voltage = (current) x (resistance)
Voltage = (1.5 A) x (2 ohms)
In order to MAKE 1.5 A of current flow through the toy car, you have to PROVIDE 3 volts from the battery.
Answer:
the final speed of the barrier would be 40m/s
Explanation:
Hello, I think I can help you with this.
the momentum is given by:
P=m*v, where P is the momentum, m is the mass of the object and v is the speed of the object.
if the momentum is transferred completely it means that the barrier will have the same amount of momentum, in other terms
momentum of the moped=momentum of the barrier
mass of the moped*speed of the moped=*speed of the barrier
let's isolate the final speed of the barrier
final speed of the barrier is
so, the speed is 40 m/s
Answer:
A- The ball has both kinetic and potential energy,
Explanation:
kinetic energy by virtue of its motion.
potential energy by virtue of its position. (It could roll off the edge of the tabel and convert gravity potential energy to kinetic energy)
Answer:
the answer to the question is indeed B
Work = N × m = 50 x 40 = 2000 J
