If the two cars traveling opposite directions have the same mass, then yes, the momentum of a car traveling south will have the same momentum as a car traveling north at the same speed.
Answer:
30mph
Explanation:
7.5 miles / .25 hours = 30 mph
Answer:
Temporary? You have two options
If you have a positively charged object, bring it close to the LEFT side of the ball (not touching it!).
If you have a negatively charged object, bring it close to the RIGHT side of the ball (again, not in contact).
Either way, the electron cloud will migrate towards the right side of the of your sphere.
Another option is to have a capacitor large enough to house the sphere inside it, and polarize it by attaching it to a DC source making sure that the negative plate of it is to the right of the sphere.
Answer:
Quantity with direction and magnitude
Displacement
Explanation:
Answer:
The strength of the magnetic field is 0.0842 mT
Explanation:
Given:
Velocity of rod 
Length of rod 
m
Induced emf across the rod 
V
According to the faraday's law
We have a special case for moving rod in magnetic field.
Induced emf in moving rod is given by,
Where 
strength of magnetic field
T
mT
Therefore, the strength of the magnetic field is 0.0842 mT
