Divide 2500 g by 500 cc. The quotient is 5 g/cc ... the density.
Answer:
D) No, because of the way work is defined
Explanation:
The work done on an object is given by:

where
F is the force applied on the object
d is the displacement of the object
is the angle between the direction of the force and the displacement
From the formula, we observe that if there is no motion involved, then the displacement of the object is zero:
d = 0
As a result, the product in the formula is also zero, therefore the work done will be zero as well.
Answer:
C. A force must be acting on the object.
Explanation:
This is due to the action of its momentum direction.

Answer:
The electric charge passes is 15.2 C.
Explanation:
The electric current is drawn from a battery = 16 A
The diameter of copper wire is = 5 mm
The length of copper wire is = 1.52 m
Running time of starter motor before the start of car engine = 0.95 s
Therefore, the current 16 A passes through the copper wire for 0.95 seconds.
The calculation of electric charge passes:
