Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
Answer:4. Two charged objects have a repulsive force of 0.080 N. If the distance separating the objects is tripled, then what is the new force? Explanation: The electrostatic force is inversely related to the square of the separation distance.
Explanation:
Answer:
65 m/s
Explanation:
The motion of the supply along the horizontal direction is a uniform motion with constant speed. Therefore, its horizontal velocity is given by
![v=\frac{d}{t}](https://tex.z-dn.net/?f=v%3D%5Cfrac%7Bd%7D%7Bt%7D)
where
d is the distance travelled horizontally
t is the time taken
In this problem, d = 650 m and t = 10 s, so if we apply the formula we get
![v=\frac{650 m}{10 s}=65.0 m/s](https://tex.z-dn.net/?f=v%3D%5Cfrac%7B650%20m%7D%7B10%20s%7D%3D65.0%20m%2Fs)
If the volume is the same and the temperature increases, then the molecules will move around faster and bump more against the balloon, so the pressure will increase.
Transverse Waves: Displacement of the medium is perpendicular to the direction of propagation of the wave.
Longitudinal Waves: Displacement of the medium is parallel to the direction of propagation of the wave.
