A light shines up from the bottom of a fish pond.Which diagram shows the correct path of light as it leaves the water of the pond and hits the air?

Answers

Answer 1

Answer: For the question "A light shines up from the bottom of a fish pond. Which diagram shows the correct path of light as it leaves the water of the pond and hits the air?" The second diagram is the correct answer. Water has a higher refractive index than air so the ray of light passing from water to air will be refracted away from the normal (the vertical) towards the surface of the water.

Which two of the following are the densest of the materials shown? Material Mass (g) Volume (L)

Rock 1000 0.5

Pillow 200 10

Bottle of soda 2000 2

Loaf of bread 100 1

rock and bottle of soda

loaf of bread and rock

loaf of bread and pillow

bottle of soda and loaf of bread

Answers

Explanation:

The density of the material is given by,

Density = $(mass)/(Volume)$

Case 1: Rock

Density = $(mass)/(Volume)$

Density = $(1000)/(0.5)$

Density = 2000 $(g)/(L)$

Case 2: Pillow

Density = $(mass)/(Volume)$

Density = $(200)/(10)$

Density = 20 $(g)/(L)$

Case 3: Bottle of Soda

Density = $(mass)/(Volume)$

Density = $(2000)/(2)$

Density = 1000 $(g)/(L)$

Case 4: Load of bread

Density = $(mass)/(Volume)$

Density = $(100)/(1)$

Density = 100 $(g)/(L)$

Thus, rock and bottle of soda has maximum density.

Definition of transalatory motion

Answers

Translational motion is the motion by which a body shifts from one point in space to another. One example of translational motion is the the motion of a bullet fired from a gun. An object has a rectilinear motion when it moves along a straight line. Hope this helps! :)

Answer:

Translational motion is the motion of body where body moves in the linear path. It is the motion in which all points of a moving body move uniformly in the same line or direction.

What is an example of a compressional wave?

Answers

Sound is an illustration of a compressionalwave. Mechanical waves like sound waves need a medium to travel through, such air, water, or solids.

A sound wave undergoes compressions and rarefactions as it passes through a medium.

Particles in the medium move parallel to the wave's propagation direction during a compressional wave.

When particles are close to one another, compression regions arise in the case of sound waves, creating high-pressure zones.

Following these compressed zones are rarefactions, when the particles are dispersed and low-pressure areas develop.

Thus, sound is an example of a compressional wave.

Answer:

The wave front expanding out from an explosion is possibly the most dynamic example of a compressional wave. And a pulse of compressed air can transfer a LOT of energy. ... For a literal "compression wave" visualize accelerating a boat across the water, compressing the water it encounters into a "bow wave".

What acceleration does a 9 N force produce in a 3 kg object? Make sure to show your work. (The 4 steps)

Answers

Answer: 3m/s^2

Explanation:

Given that:

Acceleration of object = ?

Force = 9 N

Mass of object = 3 kg

Since force is the product of the mass of an object and the acceleration by which it moves i.e Force = mass x acceleration

9N = 3kg x acceleration

Acceleration = 9N/3kg

Acceleration = 3m/s^2 (3 metres per second square)

Thus, an acceleration of 3m/s^2 is produced.

two objects were lifted by a machine. one object had a mass of 2 kilograms and was lifted at the speed of 2 m/s. the other had a mass of 4 kilograms and was lifted at a rate of 3 m/s. which object had more kinetic energy while it was being lifted?"

Answers

to find the kinetic energy KE=1/2 × mass × velocity ^2
for object 1 ke= 1/2(2)(2^2)=4 J
for object 2 ke= 1/2(4)(3^2)=18J
meaning object 2 as more kinetic energy
