Amy has a mass of 30 kg, and she is riding a skateboard traveling 5 meters per second.
What is her momentum?
5 kg⋅m/s
6 kg⋅m/s
30 kg⋅m/s
150 kg⋅m/s
Answer:
A is correct
Explanation:
Momentum is the product of mass and velocity of the moving object. The momentum of Amy weighing 30 Kg riding with 5 m/s is 150 Kg m/s.
What is momentum?Momentum is a physical quantity measuring the product of mass and velocity of a body. There are both linear momentum and angular momentum. Angular momentum is the momentum associated with a rotating body.
Momentum of a body increases with increase in mass and velocity.
The mass of the girl is given 30 Kg riding with a velocity of 5 m/s. Thus her momentum can be calculated as:
p = m v
= 30 Kg × 5 m/s
= 150 kg m/s.
Therefore, the momentum of Amy is 150 Kg m/s.

Objects too far away from the Sun do not orbit it. Explain why this occurs.
Answer:
The Sun's gravitational pull is not as strong as objects get farther away
Explanation:
Answer:
The answer would probably be gravitational pull
Explanation:
The farther an object is from the sun and the slower it will orbit the sun. If an object is closer from an other star than to the sun, or the field of attraction of this star is stronger than the one of the sun, this object will not orbit the sun at all.

what is santa's average speed when visiting houses if he visits 800 million houses over 48 hours?
Well, "speed" normally = (total distance covered) / (time to cover the distance).
In this case, we don't know the total distance that Santa has traveled, so the question can be answered only if we're willing to consider some other meaning of "speed".
Maybe we could say that in this case, "speed" means the average rate at which he visits houses. Then ...
Speed of visits = (total houses visited) / (time to visit them).
Speed of visits = (800 million houses) / (48 hours)
Speed of visits = 16.67 million houses per hour.
That's 277.8 thousand houses per minute
That's 4,630 houses per second

Read this excerpt from Through the Looking-Glass by Lewis Carroll.
“This must be the wood,” she said thoughtfully to herself, “where things have no names. I wonder what'll become of MY name when I go in? I shouldn't like to lose it at all—because they'd have to give me another, and it would be almost certain to be an ugly one. But then the fun would be trying to find the creature that had got my old name! That's just like the advertisements, you know when people lose dogs—‘ANSWERS TO THE NAME OF “DASH”: HAD ON A BRASS COLLAR’—just fancy calling everything you met ‘Alice,’ till one of them answered! Only they wouldn't answer at all if they were wise.”

A science teacher shows his students an image of a volcanic mountain range and informs them it was created by the movement of Earth’s tectonic plates. He asks his students to explain how this occurred. Which student’s explanation is best?
Student A
An oceanic plate converged with an oceanic plate. Both plates subducted, forcing lava upward towards the surface of the Earth causing a volcanic eruption which created the mountains.
Student B
A continental plate converged with a continental plate. Neither plate subducted so lava was forced upward towards the surface of the Earth causing a volcanic eruption which created the mountains.
Student C
An oceanic plate converged with a continental plate. The more dense, continental plate sank below the less dense oceanic plate causing magma to rise up through a weak spot in Earth’s crust to create volcanic mountains.
Student D
An oceanic plate converged with a continental plate. The more dense, oceanic plate sank below the less dense continental plate causing magma to rise up through a weak spot in Earth’s crust to create volcanic mountains.

A. Everywhere
B. Center
C. Lower left side
D. Upper right side
A. physical
D. Upper right
Answer:
1.) A, a physical change
2.) D, Upper right side
Explanation:
1.) Changing states does not atomically change the chemical build up of any object. Water is still water whether as liquid H2O, ice, or water vapor. Since it is only changing how an object looks and not the chemically make up, melting and freezing constitutes as physical changes
2.) Non-metals are elements that do no share the traits and characteristics of a metal. Most non-metals classify as a gas. This includes : helium, hydrogen, oxygen, carbon, nitrogen, and sulfur just to name a few.
Where are all these elements found on the table? The right sides of the periodic table.
