O gravity and velocity
O velocity and mass

Answer:
velocity and mass
Explanation:
When a substance freezes, its atoms become locked in place so they do not move from one position to another. Therefore, any substance that is frozen is a
plasma.
gas.
liquid.
solid.
When a substance freezes, its atoms become locked in place so they do not move from one position to another. Therefore, any substance that is frozen is a solid. Hence, option (D) is correct.
What is solid?One of the four basic states of matter is solid (the others being liquid, gas, and plasma). The least solid molecules are those that are tightly packed together and make up solids.
A solid is distinguished by its structural rigidity and resistance to external forces. A solid substance, unlike a liquid, does not flow to conform to the shape of its container or, like a gas, expand to cover the entire space. A solid's atoms are connected to one another either in a regular geometric lattice (such as that found in metals and common ice), or in an asymmetrical manner (an amorphous solid such as common window glass).
Therefore, any substance that is frozen is a solid.

A geologist sees a fault along which blocks of rock in the footwall have moved higher relative to blocks of rock in the hanging wall. What type of fault is this? Explain how you know.
Answer: Normal fault
Explanation:
The type of fault that is explained above is a normal fault. We should note that normal faults typically takes place in a divergent boundary in a scenario where the crusts may have been pulled apart.
Since the crust is pulled apart in this case, it leads to the downward movement of the hanging wall which leads to the football being above the hanging wall.

A rock is thrown with a force of 500 N and an acceleration is 75 m/s^2. What is its mass?
A. 575 kg
B. 3.8 x 104 kg
C. 0.15 kg
D. 6.7 kg
Answer:
We conclude that the mass of a rock with a force of 500 N and an acceleration of 75 m/s² is 6.7 kg.
Hence, option D is correct.
Explanation:
Given
Force F = 500 NAcceleration a = 75 m/s²To determine
Mass m = ?
Important Tip:
The mass of a rock can be found using the formula F = ma
Using the formula
[tex]F = ma[/tex]
where
F is the force (N) m is the mass (kg) a is the acceleration (m/s²)now substituting F = 500, and a = 75 m/s² in the formula
[tex]F = ma[/tex]
[tex]500 = m(75)[/tex]
switch sides
[tex]m\left(75\right)=500[/tex]
Divide both sides by 75
[tex]\frac{m\cdot \:75}{75}=\frac{500}{75}[/tex]
simplify
[tex]m=\frac{20}{3}[/tex]
[tex]m=6.7[/tex] kg
Therefore, we conclude that the mass of a rock with a force of 500 N and an acceleration of 75 m/s² is 6.7 kg.
Hence, option D is correct.

How does density affect refraction?
Diamonds are a very dense material. Predict what would happen to the light ray if you projected it from the air through a diamond.
Answer:
The density of a material affects the speed that a wave will be transmitted through it. In general, the denser the transparent material, the more slowly light travels through it.
At what point does a rubber band have the most elastic potential energy? Explain.
Answer:
You input potential (stored) energy into the rubber band system when you stretched the rubber band back. Because it is an elastic system, this kind of potential energy is specifically called elastic potential energy. ... When the rubber band is released, the potential energy is quickly converted to kinetic (motion) energy.

A car moving with an initial velocity of 36 m/s slows down at a constant rate of -2.8 m/s^2 . What distance does the car travel after 3 seconds of deceleration? Remember to include units in your answer! *
Answer:
the distance covered by the car is 95.4 m.
Explanation:
Given;
initial velocity of the car, u = 36 m/s
acceleration of the car, a = -2.8 m/s²
time of motion of the car, t = 3 s
The distance covered by the car is calculated as;
s = ut + ¹/₂at²
s = 36(3) + ¹/₂ x (-2.8)(3)²
s = 108 - 12.6
s = 95.4 m
Therefore, the distance covered by the car is 95.4 m.
What are the 2 types of ions.

Over many years a limestone surface is exposed to slightly acidic rain. Which result is likely to occur in the limestone
Answer:
calcium carbonate is transformed into calcium sulfate
Explanation:
Limestone stones are formed by calcium carbonate (Ca Co3), when acid rain falls with a little H2SO2, a chemical reaction of the type
Ca Co3 + H2SO4 → CO2 + H2O + CaSo4
Calcium sulfate is much weaker than alatium carbonate, which is why the stone tends to break under its weigh

An empty container has a mass of 3 g. When it is filled with 5 cm3 of a liquid,
the total mass of container and liquid is 7 g. What is the density of the liquid, in g/cm3?
Answer:
THE MASS OF THE LIQUID IS 22.5 g
Explanation:
Density = 0.180 g/cm3
Side length = 5 cm
Mass = unknown
To calculate the mass of the liquid, we use the formula:
Mass = density * volume
Volume of a cube or cuboid container = l^3
Volume = 5 ^3 = 125 cm3
So therefore, the mass of the liquid is:
Mass = 0.180 * 125
Mass = 22.5 g
In conclusion, the mass of the liquid in the container is 22.5 g
