Answer:
E) e
Explanation:
Impulse is equal to the product between the force applied (F) and the time interval of the collision (
):

This means that we can calculate the force for each collision dividing the impulse by the time interval:

Let's apply the formula to each case:
A) 
B) 
C) 
D) 
E) 
Therefore, the force is the maximum for collision E).
Answer:
1. Battery
2. Copper wire
3. Nail or piece of metal (zinc, iron, or steel).
Answer:

Explanation:
magnetic flux is the count of magnetic field lines passing through a given loop or area
As we know that magnetic flux is given by the formula

here we also know that magnetic field B and plane of the coil is perpendicular in initial position
So the area vector is always perpendicular to the plane of the coil
so the angle between magnetic field and area vector is parallel to each other and this angle would be zero
so magnetic flux of the coil initially we have

None of the choices is a suitable fill-in for the blank.
The question is fishing for "solution", but that makes
the statement false and misleading.
Salad dressing is a well-blended mixture.
Blood is a well-blended mixture.
Milk is a well-blended mixture.
Petroleum is a well-blended mixture.
None of these substances is a solution.
A solution is not a well-blended mixture.
