The NGC 3603 region of space is shown below. It is a cloud of gas and dust. Stars are forming in this cloud. How would NGC 3603 be classified?
A. As a nebula
B. As a galaxy
C. As a planet
D. As a solar system
The NGC 3603 region of space is shown below. It is a cloud of gas and dust. Stars are forming in this cloud. The NGC 3603 be classified as a nebula. The correct option is A.
What is a nebula?A tiny, ball-shaped nebula is known as a planetary nebula. It generates an ionized gas that is luminous. Large and typically erratic clouds are produced by diffuse nebulae.
Due to their big stars, they typically form a cluster of stars. a cloud of gas in space that can be seen in the night sky as a vaguely discernible brilliant patch, as something black, or as a shadow against other luminous objects.
Dust and gases, primarily hydrogen and helium, make up nebulae. The mass of gas and dust eventually grows so large that it is forced to collapse by gravity. The material in the cloud's core heats up as a result of the collapse, and this hot core is the start of a star.
Therefore, the correct option is A. As a nebula.

A satellite is in orbit 36000km above the surface of the earth. Its angular velocity is 7.27*10^-5 rad/s. What is the velocity of the satellite? (The radius of the earth is 6400km.)
Answer:
v = 3.08 km/s
Explanation:
Given that,
The angular velocity of the satellite = [tex]\omega=7.27\times 10^{-5} rad/s[/tex]
A satellite is in orbit 36000km above the surface of the earth.
The radius of the earth is 6400 km
Let v is the velocity of the satellite. It can be calculated as :
[tex]v=r\omega\\\\v=(36000\times 10^3+6400\times 10^3)\times 7.27\times 10^{-5}\\\\v=3082.48\ m/s\\\\v=3.08\ km/s[/tex]
So, the velocity of the satellite is 3.08 km/s.

Answer:
A lower frequency and a longer wavelength is correct on edge 2021
please thank the person above me though, they deserve it.
These snakes can sense electromagnetic waves that have a lower frequency and a longer wavelength.
How do snakes detect?With almost ineffective hearing and vision, snakes can be extremely fast animals. Snakes can use chemoreceptors, heat, and even their tails to recognize prey and mates. With mostly ineffective hearing and vision systems, snakes can be extremely fast animals.
They also “see” in infrared. Thanks to the mechanism, they can track prey up to a meter away by the heat of their bodies. They use a simple organ, the loreal pit, located near the nostrils.

The density has a formula of d = m / V.
The volumes are given as the same.
The density will be
d_lead = 113/ V
d_aluminum = 27/V
It does not matter for this question what the volume actually is. Just note that the value of the volume is the same for each ball.
A: incorrect. If the volumes are the same, the density is not the same because the masses are different.
B: incorrect. If the density of the two balls was less than water, the two balls would float. Never going to happen unless the balls are thin shells.
C: incorrect. The exact opposite is the answer.
D: Correct. This is the answer.

If an engine can produce 670 J of energy in 1 min, how many watts can it output?
Answer:
11.2Watts
Explanation:
Given parameters:
Energy produced by the engine = 670J
Time taken = 1min = 60s
Unknown:
Number of watts it can output = ?
Solution:
This problem entails finding the power of the engine.
Power is the rate at which work is being done.
So;
Power = [tex]\frac{Work done }{time}[/tex]
Power = [tex]\frac{670}{60}[/tex] = 11.2Watts

The equation for the formation of water from hydrogen gas and oxygen gas is 2H2+O2→2H2O . How many grams of water can be made from 64 g of oxygen gas?
Answer: 144 g
the mol of the oxygen gas is 64/16 = 4 (mol)
we have:
2H2 + O2 => 2H2O
4 ------> 8
=> the mol of H2O is 8 mol
=> m(H2O) = 8.(2 + 16) = 8.18 = 144 (g)
Explanation:
Can an object with acceleration of zero be in motion?
Answer:
NO
Explanation:
if it has no acceleration then it's not moving
Answer:
Yes when the velocity is constant then the acceleration is said to be zero. Thus an object with 0 acceleration can be in motion.
Let me give you an example to make you more clear
Example:
When a car is traveling at a constant 90 km/h in a straight line has nonzero velocity and zero acceleration.
A wave with a frequency of 28 Hz has a wavelength of 6 meters. At what speed will this wave travel?
Answer:
168m/s
Explanation:
Given parameters:
Frequency = 28Hz
Wavelength = 6m
Unknown:
Speed of the the wave travel = ?
Solution:
To solve this problem, we us the wave - velocity equation:
Velocity = Frequency x Wavelength
Velocity = 28 x 6 = 168m/s
