Explanation:
do heavier objects fall faster than lighter objects?
Answer:
Heavy objects fall at the same rate (or speed) as light ones. The acceleration due to gravity is about 10 m/s2 everywhere around earth, so all objects experience the same acceleration when they fall.

The critical angle of diamond is 24 degrees. What is its refractive index?
Answer:
2.46
Explanation:
From the question given above, the following data were obtained:
Critical angle (C) = 24 °
Refractive index (n) =?
The refractive index of the diamond can be obtained by using the following formula as illustrated below:
Refractive index (n) = 1 / sine [critical angle (C)]
n = 1/sine C
n = 1 / sine 24 °
n = 1/0.4067
n = 2.46
Thus, the refractive index of the diamond is 2.46
Two kids are swinging on a swing set. If one kid is larger than the other, how would it affect their kinetic and potential energy? If they both jumped off the swing, who would fly farther? Why?
Answer:
Yes it would affect the energy. the one who is smaller would fly
Explanation:
the larger kid is carring all the weight so he would have more energy on his side and the smaller kid would fly bc he lighter and has less energy on his side.

A 1.00 kg sphere M, suspended by a string from point P, is lifted to a height h. The sphere is released and passes through the lowest point in its swing at a speed of 10.0 meters per second. [Neglect friction.]
a. Calculate the height from which the sphere was released. [Show all work including equation and substitution with units]
b. Compared to the sphere’s speed through the lowest point of its swing when released from h, the sphere’s speed through the lowest point when released from 2h would be
Answer:
(a) h = 5.1 m
(b) v = 14.13 m/s
Explanation:
(a)
We will use the law of conservation of energy. For this situation it states that:
Loss in Potential Energy of Sphere = Gain in Kinetic Energy of the Sphere
mgh = (1/2)mv²
h = v²/2g --------------- equation (1)
where,
h = height = ?
v = speed at lowest point = 10 m/s
g = 9.8 m/s²
Therefore,
h = (10 m/s)²/(2)(9.8 m/s²)
h = 5.1 m
(b)
using the equation (1)
h = v²/2g
v = √2gh
where,
v = velocity = ?
g = 9.8 m/s²
h = height = 2(5.1 m) = 10.2 m
Therefore,
v = √[2(9.8 m/s²)(10.2 m)]
v = 14.13 m/s
The height from which the sphere was released is 5.1 m
When the height is doubled, the speed of the sphere becomes 14.14 m/s.
The given parameters:
Mass of the sphere, m = 1.0 kgSpeed of the sphere, v = 10 m/sThe height from which the sphere was released is calculated as follows;
[tex]P.E = K.E\\\\mgh = \frac{1}{2}mv^2\\\\gh = \frac{1}{2}v^2\\\\h = \frac{v^2}{2g}\\\\h = \frac{(10)^2}{2(9.8)} \\\\h = 5.1 \ m[/tex]
When the height is doubled, the speed of the sphere becomes;
[tex]h = \frac{v^2}{2g} \\\\v^2 = 2gh\\\\v = \sqrt{2gh} \\\\v = \sqrt{2 \times 9.8 \times (2 \times 5.1)} \\\\v = 14.14 \ m/s[/tex]

2. If a car accelerates uniformly at a rate of
4.0 m/s2, how long will it take to reach a speed of 20
m/s, starting from rest?
Answer:
The car will take 5 seconds
Explanation:
Constant Acceleration Motion
It's a type of motion in which the velocity of an object changes uniformly in time.
If the object starts from a speed vo during a time t with an acceleration a, then its final speed is:
[tex]v_f=v_o+at[/tex]
The car is accelerating at a rate of a= 4~m/s^2 and reaches a speed of vf=20 m/s starting from rest (vo=0).
From the equation shown above, we solve for t:
[tex]\displaystyle t=\frac{v_f-v_o}{a}[/tex]
[tex]\displaystyle t=\frac{20-0}{4}[/tex]
[tex]\displaystyle t=\frac{20}{4}[/tex]
t = 5 seconds
The car will take 5 seconds

Explanation:
Given Data:
Initial Velocity = [tex]\sf V_{i}[/tex] = 20 m/s
Angle = [tex]\sf \theta[/tex] = 30°
Acceleration due to gravity = g = 9.8 m/s²

A rock fell of the edge of a cliff and encountered a displacement of 50m. The final vertical velocity of the rock was 10m/s. Find the time the rock was in the air, the horizontal velocity when the rock left the cliff and the vertical displacement the rock had.
Answer:
A.) 3.19s
B.) 0
C.) 55.1
Explanation:
Given that a rock fell of the edge of a cliff and encountered a displacement of 50m. The final vertical velocity of the rock was 10m/s.
To Find the
A.) time the rock was in the air,
Given that
h = 50m,
initial velocity U = 0,
acceleration due to gravity g =9.8m/s^2
Using second equation of motion:
h = Ut + 1/2gt^2
Substitute all the parameters into the equation
50 = 1/2 × 9.8 × t^2
100 = 9.8t^2
t^2 = 100/9.8
t^2 = 10.2
t = 3.19s
B.) the horizontal velocity when the rock left the cliff
The horizontal velocity is equal to zero since horizontal acceleration is zero.
C.) and the vertical displacement the rock had.
Using the third equation of motion.
V^2 = U^2 + 2gH
Where U = 0
V = 10m/s
Substitute all the parameters into the formula
10^2 = 0 + 2 × 9.8 × H
100 = 19.6H
H = 100/19.6
H = 5.1
The vertical displacement = 50 + 5.1
The vertical displacement = 55.1 m
Temperatures of gases inside the combustion chamber of a four‑stroke automobile engine can reach up to 1000°C. To remove this enormous amount of heat, the engine utilizes a closed liquid‑cooled system that relies on conduction to transfer heat from the engine block into the liquid and then into the atmosphere by flowing coolant around the outside surface of each cylinder.
Suppose that, in a particular 4‑cylinder engine, each cylinder has a diameter of 8.75 cm, a height of 11.3 cm, and a thickness of 3.14 mm. The temperature on the inside of the cylinders is 195.2°C, and the temperature outside, where the coolant passes, is 130.0°C. The temperature of the incoming liquid (a mixture of water and antifreeze) is maintained at 95.0°C.
What volume flow rate of coolant [tex]\frac{V}{t}[/tex] would be required to cool this engine? Assume that the coolant reaches thermal equilibrium with the outer cylinder walls before exiting the engine. The specific heat of the coolant is 3.75 J/g°C and its density is 1.070×103 kg/m3. The cylinder walls have thermal conductivity of 1.10×102 W/m⋅∘C. Assume that no heat passes through the ends of the cylinders.

Sophia was studying with Maalik about the layers of the Earth. They were given several different statements about the layers. Which statement about the layers would they identify as correct?
A-The outer core is less than 70 km in thickness.
B-The crust assists in forming Earth’s magnetic field.
C-The mantle is denser than the crust.
D- Pressure increases when moving from the core to the crust.
The statement about the layers of the Earth that both Sophia and Malik would identify as correct is: C. The mantle is denser than the crust.
Earth is one of the planets that rotates on its axis and revolves around the Sun. Also, planet Earth is the only planet known to harbor and support life.
Based on astronomical records, planet Earth comprises four (4) distinct layers starting at the center and these include:
The inner coreThe outer coreThe mantleThe crustThe mantle has a density of 4.5 [tex]g/cm^3[/tex] while the crust has a density of 2.6 [tex]g/cm^3[/tex] because temperature and pressure within planet Earth increases with depth.
In conclusion, the mantle is denser than the crust since it is made up of metals rather than solid rocks and minerals which are found within the crust.

A box sitting still on the ground by itself has a Normal Force of 700N, what is the mass? (gravity’s acceleration is 9.80 m/s²)
Answer: 71.43 kilograms
This value is approximate rounded to two decimal places.
=====================================================
Explanation:
The ground is pushing up with a normal force of 700 N. Because the box is sitting still, this means the force of gravity is pulling the box down with a force of 700N to keep things balanced.
If the force of gravity was greater than 700N, then the box would fall through the ground. If the force of gravity was smaller than 700N, then the box would be accelerated upward. Since neither event is happening, the force of gravity must be equal to the normal force.
Now turn to Newton's second law which says
F = ma
where F is the force, m is the mass and 'a' is the acceleration. We're given the acceleration of gravity is roughly 9.80 m/s^2. So a = 9.80
The force we'll plug in is F = 700. The value of m is unknown, but we can solve for it as such
F = ma
700 = m*9.80
700 = 9.08m
9.80m = 700
m = 700/9.80
m = 71.4285714285714
m = 71.43
The mass is roughly 71.43 kilograms.
