Answer:
Final speed, v = 1.25 m/s
Explanation:
Given that,
Mass of skater A, 
Initial speed of skater A, 
(x axis)
Mass of skater B, 
Initial speed of skater B, 
(y axis)
It is mentioned that the two skaters collide and cling together. It is case of inelastic collision in which momentum remains conserved. Let V is the final speed of the couple. It is given by :
So, the final speed of the couple is 1.25 m/s. Hence, this is the required solution.
Answer:
"Motion is the act of moving or changing position. When studying motion there are many factors to look at. The main factors of motion revolve around force, speed, velocity, acceleration, and an object's mass".

Answer:
(C)
Explanation:
Volume is independent of the mass. Volume depends on the spatial dimensions so no matter how much you change the mass, volume will remain the same.
Answer:
Voltage in the primary winding of the coil is 3.9 V
Explanation:
As we know by the principle of transformer we have
here we know that
now we have
The relationship between electrical and charge force is that electrical force strengthens and increases the energy pulses and reflects off an object and makes the force about two times greater with charge.
