Answer:
Yes
Explanation:
Momentum before collision = momentum after collision
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
The cars stick together after the collision, so they have the same final velocity.
m₁u₁ + m₂u₂ = m₁v + m₂v
m₁u₁ + m₂u₂ = (m₁ + m₂)v
Plug in values and solve (take Jay Z's direction to be positive):
(1100) (-20) + (1475) u₂ = (1100 + 1475) (7)
u₂ = 27.1 m/s
Yes, Jay Z was speeding.
If you really want to find out the answer just pray about it and it will come to you..
The correct option is out of the screen.
As the motion of positive charge is the direction of current in the wire. From the right-hand curl rule, the magnetic field direction will be outside the paper or the screen. As the <span>wire runs left to right and carries a current in the direction from left to right, the magnetic field lines will be outside the screen.</span>
It is called a photon i believe
Option C: Later in the day, less power is developed in lifting each box
