You didn’t give me descriptions, but I’ll describe the Milky Way anyway
It is 100 thousand light years in diameter
It is a huge cloud of star creating gas
We live in it
It is a spiral galaxy
Hopefully this helped ☺️

What is the wavelength of microwaves of 3.0 X 10^9 Hz frequency?
GarryVolchara [31]
Given,

Frequency of microwaves = 3 x 10^9 Hz

We know that,

Velocity (c) = Frequency x Wavelength
Velocity of light (c) = 3 x 10^8 m/s

Therefore,

Wavelength = Velocity ÷ Frequency = (3 x 10^8) ÷ (3 x 10^9) = 0.1 m

Which of the following has the most momentum? proton (m=1.67 x 10-27 kg) moving at 2.0 x 104 m/s,an electron (m=9.11 x 10-31 kg)
Tom [10]

Answer:

The North American tectonic plate.

Explanation:

recall the formula for momentum: p = m * v

the subatomic particles have very small masses while high speeds, so the product results in values with negative exponents in scientific notation.

Negative exponents also result for the house fly when converting mg into kg (10^-6).

The positive exponents in scientific notation for the momentum come for the gigantic mass of the continental plate which exceeds the negative exponents contributed by the small velocity.

A mass m is attached to an ideal massless spring with spring constant k. In experiment 1 the mass oscillates with amplitude a, a
JulijaS [17]

The experiment's time period is unaffected by the change in amplitude in either experiment.

<h3>What are the variables that affect time in SHM?</h3>

The time frame is provided by:

$T=2 \pi \sqrt{\frac{m}{k}}$

where,

T = Time period.

M = mass.

k = spring constant.

We can see from the formula above that the only factors affecting the time period in a Simple Harmonic Motion (SHM) are the object's mass and spring constant. Any changes in the object's mass or the spring constant will cause the time period to adapt.

<h3>Describe the Spring Constant.</h3>

The attribute is known as a spring's "spring constant" describes the relationship between the force acting on a spring and the displacement it causes. In other terms, it describes the stiffness and size of a spring's range of motion.

Speed<br><br> Is speed a vector? Why or why not?
Murrr4er [49]

No, speed is not a vector. it is scalar.

because it doesn't need direction but need magnitude.
