Answer:
1398.12 N
Explanation:
We define the x-axis in the direction parallel to the movement of the truck on and the y-axis in the direction perpendicular to it.
x-components of the ropes forces
T₁x = 615N*cos31°=527.1579 N :Tension in direction x of the rope of the car 1
T₂x= 961 N*cos25°=870.96 N :Tension in direction x of the rope of the car 2
Net forward force exerted on the truck in the direction it is headed (Fnx)
Fnx = T₁x + T₂x
Fnx = 527.1579 N + 870.96 N
Fnx = 1398.12 N
Answer:proton as they bear positive charge and located at the nucleus
Average velocity = displacement / time
In this case, since you move left 60, then right 60, you return to the starting point making the displacement zero.
average velocity = 0 / 60 sec = zero
the average speed is calculated using total distance traveled.
average speed = distance / time
average speed = 120 meters / 60 sec = 2 m/s
Answer:
It will take time=7.963 hours to completely discharge
Explanation:
The energy available in the battery is:
Energy stored=Power×Time
Energy stored=(ΔV)I×t
Energy stored=(12.0V×43.0A.h)
Energy stored=516 W.h
The two headlights together consume a total power of:
So the time required to completely discharge is:
It will take time=7.963 hours to completely discharge
