Answer:
near Y
Explanation:
the electric field lines goes from a positive charge to a negative charge. This means that a positive charge would move in the same direction of the field lines, while a negative charge would move in the opposite direction of the field lines. the field lines are created from +vely charged plate to -vely charged plate so the negative charged particles moves towards the lower plate which is positively charged, and opposite to the direction of field lines.
Answer:
Velocity of truck is 21.875 m/s.
Explanation:
Given:
Mass of the car (m) = 2500 kg
Initial speed of the car (u) = 35 m/s
Mass of the truck (M) = 4000 kg
Initial speed of the truck (U) = 0 m/s (Rest)
As per question, the total momentum of the car gets transferred to the truck.
Therefore, the final momentum of the car is 0.
Momentum is given as the product of mass and velocity.
So, if momentum becomes zero means the velocity becomes 0.
Therefore, final velocity of the car (v) = 0 m/s
Let the final velocity of truck be 'V' m/s.
Now, during collision, the total momentum remains conserved.
Initial momentum = Final momentum.
Initial momentum of car + Initial momentum of truck = Final momentum of car + Final momentum of truck.
⇒
Therefore, the velocity of the truck is 21.875 m/s.
