Answer:
acceleration and mass are inversely proportional values
Explanation:
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:
Explanation:650
colour* wavelength (nm) energy (eV)
red 650 1.91
orange 600 2.06
yellow 580 2.14
green 550 2.25
This is a transform Boundrary
Newton would not agree with that explanation, and he would tell my brother to go to his room. Then Newton would turn to me and explain:
Once the soccer ball is in motion, it will continue moving in a straight line with constant speed, until external forces change its motion. (Newton's #1 Law of Motion).
There are external forces on the soccer ball after the kick: gravity, air resistance, and scraping through grass.
Gravity has no effect on its horizontal motion. But air resistance and scraping through grass are both friction ... they both rob kinetic energy from the ball. Once the kinetic energy of the ball is all gone, it doesn't move any more. An observer looking at the ball and measuring its motion would write in his notebook "The ball has stopped." .
The correct option is C i..e.
change the second medium to get a greater difference than before in the speed of light in the two mediums
Explanation: whenever light goes from one medium to another, kts frequency remains unchanged. It totally depends on tbe refractive index of the medium, which can change the speed of light.
If the refractive index of the entering medium is less than that of the medium from which light came,then the angle will be wider.
