Calculate the amount of current flowing through a circuit when the resistance is 2 ohms and the voltage supplied is 10 Volts.

Answer:

Speed is a "scalar" quantity

(C) is the correct answer

An object could travel at 10 m/s to some point and then return to the origin at 10 m/s for an average speed of 10 m/s, however it's displacement over that time would be zero for a net velocity of zero.

Answer:

"Both students are correct. When light is traveling through small openings, solids, liquids, gases, or a vacuum, it behaves like a wave. When it interacts with matter, it acts like a stream of particles."

Explanation:

Answer: 10 million degrees

Hope this helps :)

Given that the object is moving due north at 32 m/s, this simply expresses the velocity of the object.

This is a quantity that has magnitude but no direction. Examples include energy, work, speed, distance etc

This is a quantity which have both magnitude and direction. Example include acceleration, velocity, moment, displacement etc

Velocity is the rate of change of displacement with time.

Velocity = displacement / time

Velocity can be written as 4 m/s due east

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.

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

We know the formula

So

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

The Rigel is more warmer and brighter as compared to the sun due to its high temperature.

The Rigel is more warmer and brighter as compared to the sun due to its high temperature and its brightness is about 47,000 times more than that of the Sun. Because of its high temperature, the Rigel is white as compared to the sun.

So we can conclude that the Rigel is more warmer and brighter as compared to the sun due to its high temperature.

As the box begins to oscillate, it will have minimum velocity at maximum displacement and maximum velocity at minimum displacement.

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.

The dielectric constant of the unknown material is 2.3.

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.

Answer:

b, c and d are correct ;)

Explanation:

The field of science that gives us the idea that spacetime is not just a flat grid but is itself a physical entity that can be bent and molded is known as quantum mechanics. Thus, the correct option for this question is C.

Quantum mechanics may be defined as a fundamental theory in physics that significantly provides a detailed description of the physical properties of nature at the scale of atoms and subatomic particles. It is basically the branch of physics that deals with the behavior of matter and light on a subatomic and atomic level.

Time dilation in the theory of special relativity is the “slowing down” of a clock as determined by an observer who is in relative motion with respect to that clock.

General relativity is the theory of gravity. The basic idea is that instead of being an invisible force that attracts objects to one another, gravity is a curving or warping of space. The more massive an object, the more it warps the space around it.

Therefore, quantum mechanics is the field of science that gives us the idea that spacetime is not just a flat grid but is itself a physical entity that can be bent and molded. Thus, the correct option for this question is C.
