What is the ohms law

Answers

The Ohm's law is I(the strength of the current flowing in a conductor)= V(the potential difference applied to the ends) divided by R(resistance)

If a wave hits a smooth surface at an angle of incidence of 40 degrees, the angle of reflection is A. 40 degrees.
B. 0 degrees.
C. 90 degrees.
D. 80 degrees.

Answers

the angle of incidence is equal to the angle of reflection. If a wave hits a smooth surface at an angle of incidence of 40 degrees then the angle of reflection is 40 degrees.

D. 80 degrees.

The part of the ear where sound wave compressions and rarefactions cause the eardrum to vibrate is the middle ear. The 8th nerve in the inner ear actually converts the mechanical energy to electrical energy for transmitting to the brain. A membrane called the tympanic membrane separates the middle ear from the outer ear. Whenever a sound reaches the ear, it creates a sound wave that creates vibration in the eardrum. The pressure when high pushes the membrane inwards while low pressure sound waves helps the eardrum to come outwards.

Which explanation of the solar system best fits the observations of the planets and how they orbit the sun? (Points : 3)       The gravity of a large, massive star passing the sun ripped off blobs of material from it that formed the planets.The planets formed at the center of a collapsing spinning cloud of gas and dust.
       The sun and planets formed from a collapsing spinning cloud of gas and dust.
       A comet hit the sun and sent off fragments that became the planets.

Answers

From those choices, the best is the third one. it relates to why the sun and almost everything else in the solar system spins in the same direction, and also why the abundance of various elements in the planets is so different from what it is in the sun.

What causes light to bend when it moves from one transparent medium to another?a change in amplitude

a change in color

a change in frequency

a change in speed

Answers

Answer: The correct answer is - change in speed.

When light travels from one transparent medium to another transparent medium, it bends and this phenomenon is known as refraction.

It is caused due to difference in the speed of light in different medium as speed of light is slow in a denser medium (like water) whereas speed is faster in a lighter medium (like air).

change in speed is the answer
