Materials that let light pass through them?
Answers
Answer:
Materials that allow most all light to pass through them are called transparent. Examples of transparent items are glass, water, and air. Those materials that allow some light to pass through them are called translucent and include things like frosted glass and wax paper.
Answer:
They are transparent
Explanation:
Because they simple allow light to pass though instead of obstructing it
A child easily pushes an empty shopping cart around the store. As the cart fills, the child has to exert more force to keep the shopping moving and keep up with his mom. Which law is best supported by this example?
A. Newton's First Law
B. Newton's Second Law
C. Newton's Third Law
D. The law of definite proportions
Answers
Answer:
B Newton's second law
Explanation:
An empty grocery cart is easier to move because there is less mass in an empty cart compared to a full cart. Newton's second law state that an object's acceleration depends on the mass of the object and the force applied.

A rock is at the top of a 20m tall hill. The rock has a mass of 10kg. How much potential energy does the rock have?
Answers
Answer:
Ggghhhjhhhhhbdufdusty
Answer:
2000 Joules
Explanation:
The formula for potential energy is P.E.=mgh (where M is Mass, G is acceleration due to Gravity, and H is Height)
Plug the numbers in to get P.E.=(10kg)(10m/s^2)(20m)
Multiply together to get 2000 joules
According to Hooke's law, the force necessary to stretch or compress a spring is proportional to what value?

wave traveling at 330 m/sec has a wavelength of 4.3 meters. What is the frequency of this wave?
Answers
Answer:
76.74 Hz
Explanation:
Given:
Wave velocity ( v ) = 330 m / sec
wavelength ( λ ) = 4.3 m
We have to calculate Frequency ( f ):
We know:
v = λ / t [ f = 1 / t ]
v = λ f
= > f = v / λ
Putting values here we get:
= > f = 330 / 4.3 Hz
= > f = 3300 / 43 Hz
= > f = 76.74 Hz
Hence, frequency of sound is 76.74 Hz.

Which of the following is a property of an ionic compound?
A
has a low boiling point
B
forms molecules
C
is soft and flexible
D
conducts electricity when aqueous
Answers
Answer:
D
Explanation:
ionic compounds conduct electricity when molten or dissolved in water. ionic compounds conduct electricity when dissolved in water because water molecules are attracted to ions, this weakens the strong electrostatic forces of attraction between the oppositely charged ions. thus, ions are pulled away from the lattice structure and the remaining compound dissolves in water to form aqueous solution. The presence of free moving ions enables the ionic compound to conduct electricity.

Pulling a boat forward into a docking area requires 157J of work. The boat must be pulled a distance of 5.3m. What is the force with which the boat is pulled?
Answers
Answer:
29.62 N.
Explanation:
Work = 157 J
Distance = 5.3 m
Force = ?
Work = Force * Distance
157J = Force * 5.3 m
157 J/ 5.3 m = Force
29.62 N = Force (or) Force =29.62 N
A spring with constant 559 N/m is 0.14 meters long when not stretched or compressed. You compress the spring until it is 0.07 meters long. How many joules of elastic potential energy are stored in the compressed spring
Answers
Answer:
1.46755 Joules
Explanation:
Applying,
E = 1/2ke²......................... Equation 1
Where E = Elastic potential energy of the spring, k = spring constant, e = extension
From the question,
Gieven: k = 559 N/m, e = (0.14-0.07) meters = 0.07 meters
Substitute these values into equation 1
E = 1/2(599×0.07²)
E = 2.9351/2
E = 1.46755 Joules
