A. Exactly 50 grams matter cant be created or destroyed
Answer:
0.25 kg
Explanation:
Newton's second law states that:
where
F is the net force acting on an object
m is the object's mass
a is its acceleration
In this problem, we have:
is the force exerted on the object
m is the ball's mass
is its acceleration
Solving the formula for m, we can find the ball's mass:
M = 4kg
F =8N
a..?
F =m.a
8 = 4.a
a = 2m/s^2
Answer:
1.)The field energy will increase.
The rest of the answers:
2.)The energy increases, and the lines of force are denser
3.) It points toward the field of earths magnetic poles.
4.) l, ll, and lll only
5.) ll, lV, l, lll
