If you have two waves, one with a frequency of 4.4 x 1010 Hz and one with a frequency of 3.6 x 1014 Hz, which has the highest energy? Justify your answer
with evidence from the lesson and/or mathematically.
Answer: frequency of 3.6 x 10^14 Hz
Explanation:
If someone have two waves, one with a frequency of 4.4 x 1010 Hz and one with a frequency of 3.6 x 1014 Hz, the one with higher frequency ( 3.6 × 10^14) will have the higher energy.
From electromagnetic spectrum,
E = hf
Where
E = energy
F = frequency
h = Planck constant
The one with higher frequency will have the higher energy since energy is directly proportional to the frequency.
The one with higher frequency ( 3.6 × 10^14) will have the highest energy.
What is the frequency?Frequency is the number of oscillations per second in the sinusoidal wave.
If someone have two waves, one with a frequency of 4.4 x 10¹⁰ Hz and one with a frequency of 3.6 x 10¹⁴ Hz.
From electromagnetic spectrum, energy associated with the frequency is
E = hf
Where, E = energy, f = frequency and h = Planck constant
The Planck's constant is the constant value. The energy is directly proportional to the frequency.
Thus, The one with higher frequency will have the higher energy since energy is directly proportional to the frequency.

Explanation:
Thats the answer
Which of the answers shows three examples of a physical change
A vector points 12.0 units along the x-axis, and 9.00 units along the y-axis. Find the direction of the vector
The resultant points somewhere between the positive x and y axes.
The angle it makes with the x-axis has a tangent of (9/12) = 0.75 .
That angle is 36.9°, rounded to the nearest tenth of a degree.
So the resultant vector points up and to the right, 36.9° above the x-axis.

The way a rock reflects light is called the rock's
A. streak
O B. luster
O C. cleavage
D. specific gravity
The way a rock reflects light is called the luster of the rock. Hence option B is the correct answer.
What is Reflection?When light rays bounce off one surface, transition from one transparent medium to the next, or proceed through a media whose structure is constantly shifting, they change direction.
According to the law of reflection, the angle of the reflected ray when reflecting from a level surface is the same as the angle of the ray. (By practice, all angles in wave propagation are expressed with regards to the normal to the surface, or to the line that is perpendicular to it.
The light beam and the surface normally establish a plane in which the reflected beam is always located. The pictures created by straight and curved mirrors can be understood using the

How do you inhibitors work
Answer:
By binding to enzymes' active sites, inhibitors reduce the compatibility of substrate and enzyme and this leads to the inhibition of Enzyme-Substrate complexes' formation, preventing the catalyzation of reactions and decreasing (at times to zero) the amount of product produced by a reaction.

(A) 18.5 m/s
(B) 14.6 m/s
(C) 14.0 m/s
(D) 12.8 m/s
(E) 12.0 m/s
Can you just take a picture of your work clearly because I have to show work. Thanks.
Answer:
18.5 m/s
Explanation:
Take down to be positive.
Given:
Δy = 10.0 m
v₀ = 12.0 m/s
a = 9.8 m/s²
Find: v
v² = v₀² + 2aΔy
v² = (12.0 m/s)² + 2 (10 m/s²) (10.0 m)
v = 18.5 m/s

How does a force do negative work on an object
Answer:
Explanation:
How does a force do negative work on an object ; This is when the direction of motion is opposite to the direction of the force
To solve this we must be knowing each and every concept related to work. Therefore, a force do negative work on an object, when the direction of motion is opposite to the direction of the force.
What is work?A task requiring mentally or physically effort in order to accomplish a goal or outcome is referred to as labor in general. When we lift heavy objects off the ground or push or pull large objects, we are performing labor. When the direction of motion is opposite to the direction of the force, work is negative.
Another word we frequently use is energy. Energy and amount of work performed are typically associated, because a person who's really feeling particularly excited is capable of accomplishing a lot of work.
Therefore, a force do negative work on an object, when the direction of motion is opposite to the direction of the force.

Identify that all objects exert a force of gravity on all other objects in the universe
Answer:
It's like the Earth pulling on you and keeping you on the ground. That pull is gravity at work. Every object in the universe that has mass exerts a gravitational pull, or force, on every other mass. The size of the pull depends on the masses of the objects.
Explanation:
There is a large box and a small box on a table. The same force is applied to both boxes. The large box moves two feet and the small box moves one foot. Which movement shows the most work done? The movement of the large box shows more work because the box moved a longer distance. The work done is equal because the same force was applied to both boxes. The movement of the small box shows more work because the box moved a shorter distance. The work done was equal because both boxes moved in the same direction as the force.
Answer:
The movement of the large box shows more work because the box moved a longer distance.

What happens to sound waves after they are received by our ears?
Answer:
Our ears perceive then sound then it is transmitted to our brain where it is processed into something we can respond to. This all happens in less than a second and we are unaware that we are doing it.
Explanation:
The sound wave bounces off of the ear drum into the inner ear.
Answer:
Sound waves travel from the outer ear and in through the auditory canal, causing the eardrum to vibrate. This in turn causes three small bones in the middle ear to move. The vibrations move through the fluid in the cochlea in the inner ear, stimulating thousands of tiny hair cells.

Ax = 44.4 m and Ay = 25.1 m Find the direction of the vector.
Answer: 29.5 degree
Explanation: Given that
Ax = 44.4 m and Ay = 25.1 m
The direction of the vector will be
Tan Ø = Ay/Ax
Substitute Ay and Ax into the formula
Tan Ø = 25.1/44.4
Tan Ø = 0.5653
Ø = tan^-1(0.5653153)
Ø = 29.48 degree
Ø = 29.5 degree approximately.
Therefore, the direction of the vector is 29.4 degrees approximately.

10. Almost three-quarters of household energy use is due to the following:
• home furnaces and air conditioners
• water heaters
• washers and dryers
• lighting
For each of these uses of energy, give two reasonable ways to reduce household
energy consumption
Answer: Energy consumption and sustainability is important so that it remain available for future generation.
Explanation:
1. The home furnaces are likely to require fuel like coal, which will directly emit carbon dioxide and carbon monoxide gases. These should be replaced with the electrical furnaces. The old or more power consuming air conditioners should be replaced with new ones.
2. The water heaters should be tankless so their capacity to heat more water could be possible. The water heaters should be electricity saving.
3. Washer and dryers should be water savy and electricity savy. A front-loading washing machine is useful energy saver.
4. The LED lights are more electricity saving than conventional bulbs. Halogen lights are also electricity saving.
