Answer:
force = 21 kg m/s^2 = 21 N
Step-by-step explanation:
If an object has mass (m) 3 kg, and its acceleration (a) is 7 m/s^2, its force is given by Newton's second law of motion: Force = M * a
Force = 3 kg * 7 m/s^2= 21 kg * m/s^2
This combinations of units (kg * m/s^2) is defined as Newtons in physics and abbreviated "N".
So we can say that the force on this object is of magnitude 21 N
When simplified, y=2(x+4)+5 equals y=2x+13
Answer:
D) 2
Step-by-step explanation:
A Triangle two sides added together must always be greater than the other side.
It can not be 2 because the two sides of a triangle added are not greater than the other side.
Here 5 + 2 = 7 which is not greater than 7 on the other side, so 2 fails.
