Answer:
The primary properties of visible light are intensity, propagation-direction, frequency or wavelength spectrum and polarization, while its speed in a vacuum, 299 792 458 m/s, is one of the fundamental constants of nature.
describe the role of plate tectonics in earthquakes
Answer:
Tectonic plates are constantly moving slowly, sometimes friction between them to lock together and become unable to move.
Explanation:
What net force acting on a 14 KG wagon produces an acceleration of 1.5 MS^2?
Answer:
The wagon exerts a force of 21 Newtons
Explanation:
Force is equal to mass times acceleration, a Newton being 1 kg×m/². As we're given both the mass and the acceleration, all we need to do is multiply them to find the force applied:
14 kg × 1.5m/s²
= 14 × 1.5 kg × m/s²
= 21 N
