Answer: the correct option is A (A zero net force causes no change to an object's
motion.)
Explanation:
Force is a vector quantity that causes an object to accelerate or change velocity when pushed or pulled. While a NET FORCE can be defined as the combination of all forces acting on an object which is equally capable of accelerating the object.
When a NET FORCE is equal to zero( that is zero net force),there will be no change to an object's motion. When the net force of an object is equal to zero , it shows the object is in either static equilibrium( the objects velocity is zero) or dynamic equilibrium(where the object is moving at constant velocity). In both cases, the object remains motionless because the net forces is equal to zero.
There would be no more because everything had decrease to 0
Answer:
Density = 4.06 * 10^14
Explanation:
Givens
r = 1 * 10^-13 cm
m = 1.7 * 10^-24 grams
Formula
V = 4/3 * pi * r^3
D = m/V
Solution
Put the givens into the formula.
V = (4/3) 3.14 * (1 * 10^-13)^3 Find the value for r^3
V = (4/3) 3.14 * 1 * 10^-39 Find the volume. Indicate divide by 3
V = 1.256 10^-38/3
V = 4.1867 * 10^-39
Density = m / v
Density = 1.7*10^-24/4.1867*10^-39 Do the division
Density = .406 * 10^(-24 + 39)
Density = .406 * 10^15 grams/ cm^3
Answer: Density = 4.06 * 10^14
