How does a force do negative work on an object

Answers

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.

:What will be the value of the refractive index of the medium? Critical angle of that medium is 30 degree
a) 2
b) 1.5
c) 1.8
d) 1

Answers

Answer:

Let the second medium be air (n₁=1)

The refractive index n₂ of the medium where first medium is air is found (a)

(a) n₂ = 2

Explanation:

Critical angle can be defined as the angle of incidence that provides the angle of refraction of 90°.

Refractive index of a medium can be defined as a number that describes that how fast a light will travel through that medium.

Critical angle and Refractive index are related by:

[tex]\theta_{critical}= sin^{-1}(\frac{n_1}{n_2})[/tex]

[tex]sin \theta_{critical}=\frac{n_1}{n_2}[/tex]

To find refractive index of medium with respect to air, substitute n₁=1 (Refractive index of air is 1)

Also θ(critical)=30°

Find n₂ :

[tex]sin30= \frac{1}{n_2}\\0.5=\frac{1}{n_2}\\n_2=\frac{1}{0.5}\\n_2=2[/tex]

ОВ.
An object accelerates in the direction perpendicular to the direction of the force applied.
Ос. An object accelerates in the same direction as that of the force applied.
OD An object undergoes no acceleration on the application of force.
O E. An object's acceleration is independent to the force applied.

Answers

Answer: I think is OA.

Refer:

Newton's second law of motion states that the acceleration of a system is directly proportional to and in the same direction as the net external force acting on the system, and inversely proportional to its mass. In equation form, Newton's second law of motion is a=Fnetm a = F net m .

Ax = 44.4 m and Ay = 25.1 m Find the direction of the vector.

Answers

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.

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.

A vector points 12.0 units along the x-axis, and 9.00 units along the y-axis. Find the direction of the vector

Answers

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.

[tex]x = 158400\,in[/tex]

[tex]x = 1.584\times 10^{5}[/tex] (Choice B)

mi - km

[tex]x = (2.50\,mi)\cdot \left(1.61\,\frac{km}{mi} \right)[/tex]

[tex]x = 4.025\,km[/tex] (Different from Choice C)

mi - yd

[tex]x = (2.50\,mi)\cdot \left(5280\,\frac{ft}{mi}\right) \cdot \left(\frac{1}{3}\,\frac{yd}{ft} \right)[/tex]

[tex]x = 4400\,yd[/tex]

[tex]x = 4.40\times 10^{3}\,yd[/tex] (Choice D)

mi - cm

[tex]x = (2.50\,mi)\cdot \left(1.61\,\frac{km}{mi} \right)\cdot \left(100000\,\frac{cm}{km}\right)[/tex]

[tex]x = 402500\,cm[/tex]

The throwback PFD is which type?

Answers

Answer:a

Explanation:

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.

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

2. The strength of the bonds in system will increase and this will decrease the speed of its particles.


3. The kinetic energy of the system will increase and this will increase the speed of its particles.


4. The kinetic energy of the system will decrease and this will decrease the speed of its particles.

Answers

3 is the correct answer

The correct statement to describe that when a 100 J of heat energy is added to the system, then the kinetic energy of the system will increase  and the speed of the particles will also increase. Hence, option 3 is correct.

What is Kinetic energy?

The force that an object has because it is moving is known as kinetic energy in physics. It is defined as the quantity of effort required to accelerate anybody of a specific mass from rest to its specified velocity. The body keeps its kinetic energy after acquiring it during acceleration, barring changes in speed.

When slowing from its current pace to a condition of rest, the body expends the very same amount of energy. Any term in the Lagrangian of a system that has a derivative in regard to time is formally referred to as kinetic energy.

When the energy is added to the system the gap between the particles will increase due to which the velocity of the molecules will increase and with increase in the velocity the kinetic energy will also increase automatically.
