The throwback PFD is which type?

The Throwback PFD Is Which Type?

Answers

Answer 1

Answer:a

Explanation:

Answer 2

The throwback PFD is a Type III PFD. This type of PFD is designed for calm, inland water, or where there is a good chance of quick rescue. THe correct option is C.

Type III PFDs will not turn unconscious wearers to a face-up position, so the wearer may have to tilt their head back to avoid turning face down.

Type III PFDs have the same minimum buoyancy as Type II PFD. Float coats, fishing vests, and vests designed for various water sports are examples of Type III PFDs. Some Type III PFDs are designed to be inflated upon entering the water.

Offshore life jackets of Type I are suited for all areas, notably open, choppy, or isolated regions where rescue may be delayed and offer the highest buoyancy. Near-shore vests of Type II PFDs are designed for calm inland water or situations where there is a good probability of prompt rescue. Throwable PFDs of Type IV are suitable for usage in open water as well as calm, heavily used inland waters where assistance is always available. Special-purpose PFDs known as Type Vs are made for activities like kayaking and whitewater rafting.

The throwback PFD is not a Type I PFD because it does not provide the most buoyancy and is not designed for all waters. It is not a Type II PFD because it is not intended for calm, inland water or where there is a good chance of quick rescue.  It is not a Type IV PFD because it is not intended for calm, inland water with heavy boat traffic, where help is always present. It is not a Type V PFD because it is not designed for specific activities such as kayaking or whitewater rafting.

Therefore, the correct option is C. type III.

6. How is work related to kinetic energy?

Answers

Answer: Energy should be transferred to an object in order to move it. This amount of energy transferred by the force to move an object is called work or work done. Thus, the relation between Work and Energy is direct. That is, the difference in the Kinetic energy of an object is work done by an object. OR

The principle of work and kinetic energy (also known as the work-energy theorem) states that the work done by the sum of all forces acting on a particle equals the change in the kinetic energy of the particle. The kinetic energy of the block increases as a result by the amount of work.

(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.

Answers

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

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.

Answers

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.

What happens to sound waves after they are received by our ears?

Answers

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.

here the work done by the body is equal to its potential energy

work done=P.E.

As we know that P.E.=mgh

putting values

P.E.=60kg×20m×10m/s²

P.E.=1200kgm×10m/s²

Question 5(Multiple Choice Worth 4 points) (01.04 MC) Which of the following correctly describes the relationship between speed and velocity? Speed is the change in velocity over time; velocity is distance plus direction. Speed is the change in distance over time; velocity is speed plus direction. Speed is distance plus direction; velocity is speed plus time. Speed is the change in acceleration; velocity is distance over time.

Answers

Answer:

Speed is the change in distance over time; velocity is speed plus direction

Explanation:

Speed is defined as the change in distance covered by a body with respect to time while velocity the change in displacement of a body with respect to time. Speed is a scalar quantity since it does not specifies direction while velocity is a vector quantity because it specifies both magnitude and direction.

Speed can only be equal to the velocity if it also specifies direction.

Based on the definition above, it can be concluded that speed is the change in distance over time and velocity is speed plus direction.

Answer:

Speed is the change in distance over time; velocity is speed plus direction.

Different types of waves travel at different speeds. For example, sound waves travel more slowly than light waves. Have you ever been in a big empty room, or in a cave, and heard an echo? Echos happen because sound waves take time to travel to the wall and bounce back to your ears. But light is different. Light is much faster than sound. Light is the fastest moving thing in the universe. Because light waves and sound waves travel at different speeds, you can figure out how far you are from a storm by watching for lightning and listening for thunder. Lightning and thunder are actually the same thing! Thunder is just the sound that lightning makes. Because light is so quick, you see the lightning flash first. The sound travels more slowly, so you hear the thunder after. Thunder and lightning represent two kinds of waves: sound and light.
How do lightning and thunder illustrate the relationship between light and sound waves?
A Light moves faster than sound, so you hear thunder after you see lightning.
B Sound moves faster than light, so you see lightning after you hear thunder.
C Lightning and thunder are the same, so light and sound waves move together at the same time.
D Sound moves light, so when you hear thunder you know lightning will move toward you.

Answers

Answer:

A). Light moves faster than sound, so you hear thunder after you see lightning.

Explanation:

The lightning and thunder demonstrate that 'light travels faster than sound' which clearly portrays the relationship between the light and the soundwaves. When we see lightning in the sky before hearing the sound of thunder as the speed of light much higher than the speed of sound. Sound travels ~ 343 m/s or 1235 km/hr while light travels 300000 km/s. This difference in speed prevents us from considering lightning and thunder as the same thing. The 'sound is a pressure wave and therefore, takes time to travel and bounce back to our ears.' Thus, we happen to witness lightning first. Hence, option A is the correct answer.

A negative slope on the velocity vs. time graph indicates that the object is not
accelerating
A. True
B. False

Answers

Answer: False, I think

Explanation:

Well it depends. Its hard to say without a function of the graph. Given a velocity graph, the first derivative is the acceleration.

Negative slope on a velocity graph means you are going in the negative direction. And over time, your velocity per unit of time is also decreasing. That means we are accelerating in the negative direction

False, your velocity would just be in the negative direction.
