Blue would bend the most, since it has a greater refractive index. It has more energy and a shorter wavelength, so it slows.
Gravity is the force of attraction between objects. Gravity is that force of attraction that will cause hydrogen gas in a nebula to clump together overtime. These hydrogen atoms will form a spinning cloud of gas within the nebula.
As collisions between the atoms become more frequent, the temperature within the cloud will rise.
As the cloud gets more massive the greater the force of gravity will be and so it will attract even more gas to the spinning cloud. When the temperature reaches fifteen million degrees Celsius, nuclear fission begins and a star is born.
Answer:
Explanation:
The rest energy is the energy associated with the base ball at zero velocity which is expressed as
Note: the speed C is the speed of light which is expressed as 3*10^8
while the kinetic energy is the energy associated with the ball during its motion and is expressed as
the ratio can be expressed as
Answer:
The ladder is moving at the rate of 0.65 ft/s
Explanation:
A 16-foot ladder is leaning against a building. If the bottom of the ladder is sliding along the pavement directly away from the building at 2 feet/second. We need to find the rate at which the top of the ladder moving down when the foot of the ladder is 5 feet from the wall.
The attached figure shows whole description such that,
.........(1)
We need to find, at x = 5 ft
Differentiating equation (1) wrt t as :
Since,
At x = 5 ft,
So, the ladder is moving down at the rate of 0.65 ft/s. Hence, this is the required solution.
<span>Negatively charged particles will go toward the positive end of the magnetic field and positively charged particles will go toward the negative end... for two reasons, because the positive is both repelled by the positive part of the field, and its also attracted by the negative end. oh, and on diagrams, the arrows of magnetic flux usually go from negative to positive.
Hope this helps(:</span>
