Answer:
Plate Tectonics
Explanation:
Plate tectonics is the scientific theory that the continents move around due to due plate tectonics and the movement of magma under the crust. This explains why some fossils of the same kind are found on other continents, and same goes for the Glacial Marks.
Through the 1/r law, it was concluded that for the sound intensity or pressure is directly proportional to distance or radius. That is,
p = k/r
where k is the proportionality constant. If the distance of a sound wave is quadrupled then, the intensity of the sound is decreased to 1/4 of its original value.
Answer:
<em> It takes 186.67 second for the light to travel from Mars to earth.</em>
Explanation:
Light: Light is a visible form of energy which is radiated outward from a source. Light travels in a straight line, and this phenomenon is called rectilinear propagation of light.
S = d/t .......................... Equation 1
making t the subject of the equation
t = d/S ......................... Equation 2
Where S = speed of light, d = distance between the earth and Mars, t = time
<em>Given: d = 56000000 km, S = 300000 km per seconds.</em>
<em>Substituting these values into equation 2</em>
<em>t = 56000000/300000</em>
<em>t = 186.67 seconds.</em>
<em>Thus it takes 186.67 second for the light to travel from Mars to earth.</em>
<span>When temperature increases, particles in an object speed up, which means an increase in thermal energy. Since the particles are moving more now, the potential energy decreases, therefore kinetic energy increases.
Overall, when temp goes up, thermal energy goes up, which leads to an increase in kinetic energy.</span>
Mechanics Physics is a area in physics dealing with motion of objects talking about when force applied to objects what happens whether displacement or changes of the position
