Impulse describes the change of momentum. Since we don't know the momentum of the soccer ball before the hit, this question is hard to answer. If you assume the momentum of the ball before the hit was p = 0, then the change in momentum is just Δp = Impulse = mv.

Radial acceleration is given by

$a_{rad}= \frac{v^2}{r}$
where

$v=r \omega$
then

$a_{rad}= \frac{r^2 \omega^2}{r}=r\omega^2$

Now

$70\omega^2=3.90 \frac{m}{s^2} \\ \\ \omega= \sqrt{ \frac{3.9}{70} }$

Using the relation

$\omega=2 \pi f$

$2 \pi f= \sqrt{ \frac{3.9}{70} }\\ \\ f= \frac{1}{2 \pi}\sqrt{ \frac{3.9}{70} }Hz$

Putting into rpm

$\frac{60}{2 \pi}\sqrt{ \frac{3.9}{70}} =2.254rpm$

Comparing ultraviolet photons to radio photons, we can say that the ultraviolet photons have ______ energy, ______ frequency, an

guajiro [1.7K]

Answer:

Energy of ultra violet photons < Energy of radio waves

Wavelength of ultra violet photons > Wavelength of radio waves

Explanation:

The increasing order of the wavelength is given by

Gamma rays

x rays

Ultra violet rays

Visible radiations

Infrared rays

micro waves

Radio waves

So, ultra violet rays has larger wavelength than radio waves.

As we know that the energy is inversely proportional to the wavelength.

So, the energy of radio waves is more than the energy of ultra violet waves.

Energy of ultra violet photons < Energy of radio waves

Wavelength of ultra violet photons > Wavelength of radio waves

Water can dissolve salt because the positive part of water molecules attracts the negative chloride ions and the negative part of water molecules attracts the positive sodium ions. The amount of a substance that can dissolve in a liquid (at a particular temperature) is called the solubility of the substance. So the solute is the salt and the solvent is the water. I believe that is correct.

The moon orbiting the Earth

Explanation:

The motion of the moon orbiting the earth is a circular motion. Circular motion is simply the motion of an object in circle at constant speed.

A cannonball flying from a cannon is a projectile motion and not a circular motion.
A car moving along a straight track is a linear/translational motion.
Pendulum of a grandfather clock is a simple harmonic motion.
