Answer:
TRUE
Explanation:
The answer is true.
Balance forces acting on a body will not change the motion of the body because the body experiences no net resultant force in one direction. When any body experiences equal forces with opposite directions, the net force or the resultant force experience by the body is zero.
In case of an unbalanced forces, there is a net force acting in one direction and so it causes the body to change in its state of motion in the direction of the net force.
Answer:
A = [kg]
B = [m/s²]
Explanation:
E = ½ Av² + Bmx
Substitute the units:
[J] = ½ A [m/s]² + B [kg] [m]
A Joule written in base units is:
1 J = 1 Nm = 1 kg m²/s²
Each term must have the same units.
[kg m²/s²] = A [m/s]²
[kg m²/s²] = A [m²/s²]
A = [kg]
[kg m²/s²] = B [kg] [m]
B = [m/s²]

Sorry for waisting ur time just tryna get points :)
Explanation:
15 nitrogen atoms are in one molecule
Answer:
50.3 m/s²
Explanation:
Centripetal acceleration is:
a = v² / r
where v is velocity and r is radius.
First, calculate the velocity. Velocity is distance divided by time. The distance is the number of circumferences traveled by the ball.
v = x / t
v = (15.0 × 2π × 0.230 m) / 6.37 s
v = 3.40 m/s
Therefore:
a = (3.40 m/s)² / 0.230 m
a = 50.3 m/s²
