Answer:
Momentum of red car = 5kgm/s
Momentum of blue car = 0kgm/s
Explanation:
Momentum = mass × velocity
For the red car
Mass = 1kg
Velocity = 5m/s
Momentum of the red car = 1kg × 5m/s
Momentum of the red car = 5kgm/s
For the blue car.
Mass = 1kg
Velocity = 0m/s(shows that the blue car is stationery)
Momentum = 1kg ×0m/s
Momentum of the blue car = 0kgm/s
Answer:
electronegativity ☝️☝️☝️answer
Average speed = (total distance covered) / (time to cover the distance)
Total distance = (80m) + (125m) + (45m) = 250 meters
Overall time = 10 minutes
Average speed = (250 meters) / (10 minutes)
<em>Average speed = 25 meters/minute </em>
Since we're only looking for average speed and not velocity, we don't care about any of the directions, and we don't need to calculate Mary's displacement.
Answer:
1.8nA
Explanation:
I = dq/dt
I = 9.0 × 10 ^-12 / 0.5 × 10^-3
I = 1.8 × 10× 10^-8
