This is about scientific notation and exponents.
Newton's law of gravitation can be used to compute earth's mass in grams. Applied it is 908 = 6.67 X 10^-8 x 1 x M / (6.37 x 10^8)^2. If M represents mass, what is the mass of the earth in grams?

The other one is: The mass of a proton is 1.672 x 10^-24 g. If earth's moon's mass is 7.35 x 10^22 kg, how many times larger is its mass than tha tof a proton. For this one I have 3.895.. and so on. And i rounded to 4.4 x 10^49, but I'm not sure if the answer should have to be rounded. Thanks!

Although the particles have highly reflective surfaces, there are very few particles in the rings.

The rings are composed of small, dark rock particles.

The particles are composed of methane ice that has been darkened by radiation damage.

The particles have highly-reflective surfaces, but the rings are far from the Sun, where there is little light.

Our class is having difficulty with this projectile motion problem that we have to have submitted by tomorrow afternoon. The problem is...

"When a nurse squeezes a syringe, the liquid squirts 3.43 cm into the air. With what speed does the liquid emerge from the syringe?"

She gave us multiple choices to pick from, and in case they are helpful, I'll include them as well.

a.) 0.410 m/s
b.) 0.820 m/s
c.) 1.64 m/s
d.) 2.28 m/s

Thanks for any help!
