The speed of light traveling through an unknown material is 1.98×108 m/s. Given that the speed of light in a vacuum is 3.00×108 m/s, what is the dielectric constant of the unknown material?
The dielectric constant of the unknown material is 2.3.
What is dielectric constant?Dielectric constant is referred as a relative permittivity or amount of charge required to produce one unit of electric flux in a given medium.
Given the speed of light in vacuum c =3 x 10⁸ m/s and the speed of light through an unknown material v = 1.98 x 10⁸ m/s.
The dielectric constant is related to the velocity by the following relation,
v = c/√K
Rearranging for dielectric constant, we get
K = (c/v)²
Substitute the value into the expression ,we get
K =(3 x 10⁸ / 1.98 x 10⁸)²
K = 2.3
Thus, the dielectric constant of the unknown material is 2.3.

9. An empty, massless cube is measured to have all sides equal to 11 cm. It is floating in water and will slowly be filled with sand
that has a density of 3.5 g/cm'. What volume of sand will cause the box to sink?
Answer:
See below ~
Explanation:
An object will sink in water when its density is greater than that of water, which is 1 g/cm³.
Volume of the box is 1331 cm³. (11³)
Maximum mass of sand will be 1331 g. [because 1331/1331 = 1 g/cm³]
Volume of sand = Mass of sand / Density of sandVolume (sand) = 1331/3.5Volume (sand) = 380.29 cm³If the volume of sand is greater than 380.29 cm³, the box will sink in water.
How would increasing the magnitude of the charges on two charged particles and decreasing the distance between the particles affect the strength of the electric force between the particles?
We know the formula
F=kq1q2/rSo
if magnitude of charge is increased the force between them also increased.
And if the distance between them is decreased them also the force will be increased.
So Force increases

If the watermelon has a mass of 850g, and gravitational force is 9.81 m/s2 on Earth, what is the weight of the watermelon?
Which will hit the ground first?
Answer:
2.79 N8.34 NWatermelonExplanation:
Weight of soccer ball
Weight = mass (in kg) × gravitational forceWeight = 284 x 10⁻³ x 9.81Weight = 0.284 x 9.81Weight = 2.79 N (approximately)Weight of watermelon
Weight = mass (in kg) x gravitational forceWeight = 850 x 10⁻³ x 9.81Weight = 0.85 x 9.81Weight = 8.34 N (approximately)As the watermelon has more weight, it will hit the ground first.

The three areas of discipline are ________.
isolation
instruction
punishment
admonition
nurture
Answer:
Instruction, admonition, nurture
Explanation:
the practice of training people to obey rules or a code of behavior, using punishment to correct disobedience:A box on a spring is pushed to point A and allowed to oscillate. Describe the motion of the box at points A, B, and C. Be sure to use the words maximum velocity, minimum velocity, maximum displacement, minimum displacement, maximum acceleration, minimum acceleration, equilibrium, and restoring force where appropriate.
As the box begins to oscillate, it will have minimum velocity at maximum displacement and maximum velocity at minimum displacement.
Oscillation of the box
The force applied to box will cause a displacement of the box from equilibrium position to maximum position which increases as the applied force increases.
Therefore, as the box begins to oscillate, it will have minimum velocity at maximum displacement and maximum velocity at minimum displacement.

What will happen to the force between 2 charged objects if the mass of one of the charges is doubled and the distance between them is double?
a satellite moves in a circular orbit around the earth at a speed of 5000 ms. determine the satellites altitude above the earths surface
Answer:
G M m / R^2 = m v^2 / R centripetal force = force of attraction
R = G M / v^2 radius of satellite orbit
R = 6.67E-11 * 5.98E24 / 5000^2
R = 6.67 * 5.98 / 25 * 10^7 m = 1.60 * 107 m = 16 * 10^6 m
Radius of earth = 6.37 * 10^6 m
H = R - r = (16 - 6.4) * 10^6 m = 9.6 * 10^6 m
A common practice for a person with a high fever is to take a bath in cool water. Assuming an 80 kg person is really ill and needs to cool down from 40°C to 37°C. What is the minimum amount of water needed for bathing assuming the water begins at room temperature, 25°C?
The minimum amount of water needed for bathing assuming the water begins at room temperature is 16.58kg.
What is thermal equilibrium?When two bodies at different temperature come into contact, they share the heat through conduction. After some time, temperature of both becomes equal. This condition is said to be a body in thermal equilibrium with other.
Heat gained by the water = heat lost by the ill person
m x Cw x ΔT = M x Cp x Δt
where, mass of person M = 80kg, Cp =specific heat of body =3470, specific heat of water Cw= 4186, then mass of water m will be
m x 4186 x (37-25) =- 80 x 3470 x (37-40)
m = 16.58kg
Thus, the mass of water needed is 16.58kg.

A car of mass 800 kg travels over a hill of height h. By travelling to the top of the hill, the car gains 40000 J of gravitational potential energy. The gravitational field strength g is 10 N /kg
[tex] \sf\huge{\underline{\underline{\overbrace{Answer}}}} [/tex]
The height of the hill is 5m.
Explanation:
Given :-⠀
Mass of the car (m) = 800kg

an object is moving due north at 32m/s does this tell you the speed or the velocity of the object, or
both?
Given that the object is moving due north at 32 m/s, this simply expresses the velocity of the object.
What is a scalar quantity?This is a quantity that has magnitude but no direction. Examples include energy, work, speed, distance etc
What is a vector quantity?This is a quantity which have both magnitude and direction. Example include acceleration, velocity, moment, displacement etc
What is velocity?Velocity is the rate of change of displacement with time.
Velocity = displacement / time
Velocity can be written as 4 m/s due east
What is speed?This the distance travelled per unit time.
Speed = distance / time
Speed can be written as 4 m/s
Considering the question given above, we were told that the object is moving due north. This simply talks about the velocity.
