Are their any words that we can answer the question with?
As per Newton's II law we know that
rate of change in momentum is Net outside force on the object
now here we will have if net outside force will be zero
then we can say
so from above equation we can say
and hence we have
so the correct answer will be
<em>3.) in the absence of outside forces</em>
Answer:
The magnetic force on the moving negative charge is towards the ceiling.
Explanation:
The magnetic force acting on a wire is given by the relation as follows :
q is charged particle
v is velocity of charged particle
B is magnetic field
In this case, a negative charge is moving across a rook from south to north. A magnetic field runs from East to west.
q = -q
v =+j
B = -i
So,
Since, 
So,
So, the magnetic force on the moving negative charge is towards the ceiling.
According to Newton's first law of motion, the puck gradually slows down because friction would be acting on it.
<h3>What is Newton's first law?</h3>
Newton's first law of motion states that an object will remain at rest or move uniformly in a straight line unless acted upon by an external force.
According to this question, a hockey puck is hit with a large force. The puck moves at a high speed as it slides over the ice.
However, in accordance with the first law of motion proposed by Newton, the puck gradually slows down because friction would be acting on it.

fish have proteins known as walleye Pollock, this white fish is packed with protein. Three ounces (85 grams) contain 20 grams of protein and about 100 calories (21). Alaskan Pollock is an excellent source of omega-3 fatty acids. It also contains large amounts of choline and vitamin B12, as well as many other nutrients.
