Answer:
Acceleration
Explanation:
acceleration because it has magnitude but no direction
Answer:
The right answer is D) the total momentum of the system is 0.047 kg · m/s toward the right.
Explanation:
Hi there!
The total momentum of the system is given by the sum of the momentum vectors of each cart. The momentum is calculated as follows:
p = m · v
Where:
p = momentum.
m = mass.
v = velocity.
Then, the momentum of the system will be the momentum of cart A plus the momentum of cart B (let´s consider the right as the positive direction):
mA · vA + mB · Vb
0.450 kg · 0.850 m/s + 0.300 kg · (- 1.12 m/s) = 0.047 kg · m/s
The right answer is D) the total momentum of the system is 0.047 kg · m/s toward the right.
if it moves 7m/s, that means every second it goes 7m. Now we just multiply by the time (20 seconds) and end up with 140m.
Answer:
The flow of electric charge
Explanation:
Electricity:It is defined flow of electric charge.
It is defined as the flow of charge per unit time.
Electric charge can be negative or positive .
Mathematical representation :
If charge Q flowing through the conductor and time taken in flow of charge is t seconds.
Then, current
S.I unit of current is Ampere.It is scalar quantity.
Answer:The flow of electric charge.
