Kinetic Energy HELP! Brainly included

Answer:

bending of light

Explanation:

Answer: Refraction of light is the bending of light when it passes from rarer(less dense) medium to a denser medium or vice versa.

Explanation:  The bending of light happens as light travels at different speed in different medium for example light travels slower in water than compared to air as water is denser than air. That is why when you put a pen in a glass cup you will notice that the pen is slightly shifted (the part of the pen above water is travelling at a different speed than the part of the pen underwater).

Answer:

Diffusion is the movement of a molecule from an area where the molecule is in high concentration to an area where the molecule is in low concentration. Facilitated diffusion is the movement of a molecule from an area of high concentration to an area where the molecule is in low concentration. Osmosis is the diffusion (high to low concentration) of water through a semi-permeable membrane. Water moves from an area of high water molecule concentration (and lower solute concentration) to an area of low concentration (and higher solute concentration.

Answer:

Kinetic energy

Explanation:

Answer:

A

Explanation:

When friction slows a sliding block, the kinetic energy of the block is transformed into internal energy .

The frictional movement of two surfaces over one another leads to the conversion of some of their kinetic energies to another energy - heat or thermal energy. Hence, the temperatures of the objects are raised in the process.

Therefore, when a sliding block is slowed down due to friction, some of the kinetic energy of the block would be transformed into internal energy in the form of heat.

The correct option is A.

Answer:

Probably like around 30 - 35 years, 100-250 days and 7-14 hours

Explanation:

Time travel = 4 s

The car’s final velocity : 18 m/s

Given

initial velocity=vo= 10 m/s

acceleration = a = 2 m/s²

distance=d = 56 m

Required

Time travel and the final velocity

Solution

[tex]\tt d=vo.t+\dfrac{1}{2}at^2\\\\56=10.t+\dfrac{1}{2}.2.t^2\\\\56=10t+t^2\\\\t^2+10t-56=0\\\\(t-4)(t+14)=0\\\\t=4,t=-14\rightarrow take~a~positive~value~t=4~s[/tex]

[tex]\tt v_f=v_i+at\\\\v_f=10+2.4\\\\V_f=18~m/s[/tex]

Answer:

b).alleles

Explanation:

Every person has two copies of each gene, one inherited from each parent. Most genes are the same in all people, but a small number of genes (less than 1 percent of the total) are slightly different between people. Alleles are forms of the same gene with small differences in their sequence of DNA bases.

Genes are segments of DNA that contain the instructions for the synthesis of proteins or functional RNA molecules. They are composed of two alleles. The correct answer is b) alleles.

Genes are segments of DNA that contain the instructions for the synthesis of proteins or functional RNA molecules. They are composed of two alleles, which are alternate forms of a gene that can occupy the same locus on a specific chromosome.

Therefore, Alleles can vary in their sequence of nucleotides and can determine different traits or variations of a particular characteristic. Therefore, every gene is made up of two alleles, one inherited from each parent. The correct answer is b) alleles.

Answer:

When a body is in uniform circular motion, its speed remains constant but its velocity, angular acceleration, angular velocity changes due to change in its direction.

Answer: A and B

Explanation: Because it makes the data you have secure and can only be authorized by you.

The computer program is encoded so that only authorized users can use these data and making digital data more secure. Therefore, option (A), (B) is correct.

Encoding and decoding can be used in communications, including computing, programming, data communications, digital electronics, and human communications. These two processes include converting the format of content for optimal transmission or storage.

In computers, encoding can be described as the process of putting a sequence of characters into a specialized format for efficient transmission or storage. Decoding can be described as the opposite process where the conversion of an encoded format back into the original pattern of characters.

The encoding process can be used in various patterns of digital signals on the transmission link. The common kinds of line encoding are Unipolar, Bipolar, Polar, and Manchester.

Encoding makes use of digital data more secure as only authorized users can use these data.

[tex]a = 0.65\ m/s^2[/tex]

Explanation:

Net Force

There are four forces acting on the sled:

Its weight W directed down

The normal force N directed up

The applied force F directed left

The friction force, opposite to the motion, directed right.

The forces are shown in the free-body diagram of the figure below.

The body is in equilibrium in the vertical direction, thus:

N = W = m.g

N = 80 Kg . 9.8 [tex]m/s^2[/tex]

N = 784 Nw

In the horizontal direction, the sum of the force vectors is the net force:

Fn = F-Fr

It's assumed the left as positive.

The friction force is calculated as:

[tex]Fr =\mu_k . N[/tex]

Fr =0.125*784 Nw

Fr = 98 Nw

According to Newton's second law, the net force is equal to the mass by the acceleration:

F-Fr=m.a

The acceleration can be calculated by solving for a:

[tex]\displaystyle a=\frac{F-Fr}{m}[/tex]

[tex]\displaystyle a=\frac{150-98}{80}[/tex]

[tex]\mathbf{a = 0.65\ m/s^2}[/tex]

Answer: Physical component- state of physiological arousal triggered by autonomic nervous system

Behavioral component- outward expression of emotion, including facial expression and behavior

Cognitive component- appraisal of the situation determine which emotion we are experiencing and why.

Explanation:

hope that helps :)

The three elements of emotions are a subjective experience, a physiological response, and a behavioral or expressive response.

Emotions enable us to express our needs to others, such as when we are depressed and in need of assistance. They can also assist us in taking swift action when necessary.

For instance, panic causes you to jump back onto the curb when you're ready to cross the street, and you see a car approaching swiftly. Three components make up the “feeling” aspect of consciousness: a particular physical arousal, a particular conduct that communicates the feeling to others, and an internal awareness of the emotion.

Therefore, the elements of emotions are subjective experience, physiological response, and behavioral or expressive response.

Answer:

Explanation:

The resistance of this device is determined by using the formuia from Ohms Law:

V = IR

where; V = voltage

I = current

R = resistance

From the above equation:

R = V/ I ---- (1)

And

I = P/V    --- (2)

If 1 unit = 1 KWH = 3.6 × 10⁶ J

Then;

2.2 units = (3.6 × 10⁶ × 2.2)

= 7.92 × 10⁶ J

So, Energy = 7.92 × 10⁶ J

Also:

Power = energy/time

Power =  7.92 × 10⁶ J / 1 hour

Power = 7.92 × 10⁶ J / 3600 seconds

Power = 2200 Watts

From equation (2)

I = P/V

I = 2200/220

I = 10 A

Recall that:

Resistance R = V/I

Resistance R = 220/10

Resistance R = 22 ohms

SO, if 1 unit costs = Ts 6.00

Then the cost of 2.2 unit = 2.2 ( Rs  6.00)

= Rs 13.20

Answer:

5 cm.

Explanation:

If the glass is located upright, the height of water is about 5 cm because the height of glass is 10 cm and it is partially filled with water and we know that partial means 50 percent of something and here 50 percent of glass is 5 cm. If the glass is slightly bend, so we can't find its right height so the proper height of water is attain if it is placed on flat table and present upright.

Answer:

Solids expand when they are heated.

Explanation:

It is possible to loosen caps on the screw  top bottles by dipping the cap briefly in hot water due to the fact that whenever a solid is heated, it expands. This means that the size of the solid Screw cap (in this our case) increases as the temperature does.

This increase in size causes it to slide off easily from the mouth of the bottle when a little twisting effort is applied.
