An undiscovered planet, many light-years from Earth, has one moon, which has a nearly circular periodic orbit. If the distance f

rom the center of the moon to the surface of the planet is 2.165×105 km and the planet has a radius of 4175 km and a mass of 6.70×1022 kg , how long (in days) does it take the moon to make one revolution around the planet? The gravitational constant is 6.67×10−11N·m2/kg2 .

Answer:

The Starship Enterprise is powered by combining matter with antimatter. Suppose 1 kg of each are combined and ejected backward at the speed of light, what is the final speed of the Enterprise starting from rest? Assume that the mass of the Enterprise is 10,000 kg and the spaceship does not reach relativistic speed.

A 2.2-kg block slides on a horizontal surface with a speed of v=0.80m/s and an
mina [271]

Answer:

μ = 0.33

Equal to 3.2 m/s²

Explanation:

Draw a free body diagram of the block.  There are three forces:

Normal force N pushing up.

Weight force mg pulling down.

Friction force Nμ pushing opposite the direction of motion.

Sum of forces in the y direction.

∑F = ma

N − mg = 0

N = mg

Sum of forces in the x direction.

∑F = ma

Nμ = ma

Substitute.

mgμ = ma

μ = a/g

μ = (3.2 m/s²) / (9.8 m/s²)

μ = 0.33

As found earlier, the acceleration is a = gμ.  Since g and μ are constant, a is also constant, so it does not change with velocity.

What kind of electromagnetic radiation could be used to see molecules
Vera_Pavlovna [14]

Answer:

X ray

Explanation:

To see an object the light used must have the same or smaller wavelength than the object. The size of an atom is about 10^{10} m, smaller than the wavelength, therefore we'll need radiation with a shorter wavelength <em>since X-ray wavelengths are about the same size as atoms this characteristic makes it ideal to use.</em>

I hope you find this information useful nd interesting! Good luck!
