Answer:

0.3214 grams per millimetre

Explanation:

Answer: 32

Explanation:

D = m/v

D = 18/56

D = ?

This is an example of Uniform Speed

EXPLANATION

Uniform Speed => no change in speed

Uniform Accelerations Speed => There is a change in speed, but the acceleration remains the same.

Answer:

122.5 meters

Explanation:

We have the third equation of motion:

[tex]\boxed{\mathsf{v^2=u^2+2aS}}[/tex]

Here, the particle is a flare.

It's initial velocity is 49 m/ s and the final will be zero, that's 'cause the particle comes to a standstill upon reaching its maximum, in case of motion under gravity.

a will be the acceleration due to gravity = 9.8 m/ s²

So, here are the terms we've got for the third eqn. of motion:

Now, the term we've got to find out is the height reached by the flare, i. e., S.

=> v² = u² + 2aS

=> (0)² = (49)² + 2×(-9.8)×S

=> 0 = 49×49 - 2×9.8×S

=> 2×9.8×S = 49×49

[tex]\implies \mathsf{S=\frac{49\times 49}{2\times9.8} }[/tex]

=> S = [tex]\frac{245}{2}[/tex]

And, S is the maximum height the flare covers, so the answer is 122. 5 meters

Answer: It is b

Explanation:

The lack of protein in the body will result in a lack of energy in the body. Hence, option B is correct.

Proteins are created from a variety of amino acid building blocks. Our body needs dietary protein to supply amino acids for the growth and upkeep of our cells and tissues. As we become older, our dietary needs for protein change.

Proteins are made up of many different amino acids that are joined together. Both plants and animals have a lot of these 20 different amino acid building blocks. Each protein has a unique ratio and arrangement of the 300 or more amino acids that make up a typical protein.

Our body is made up of thousands of different proteins, each of which has a specific function. They contribute to the structural components of our cells and tissues, along with the countless enzymes, hormones, and active proteins produced by immune cells.

Computers are widely used for modeling weather systems because because weather systems are too complicated to be accurately predicted using small-scale. Hence option A is correct.

Weather refers to the condition of the atmosphere and includes terms like how hot or cold, wet or dry, quiet or stormy, clear or foggy, etc. The troposphere, which is the lowest part of Earth's atmosphere and lies just below the stratosphere, is where most meteorological events take place. Climate is the phrase for the average of atmospheric conditions over longer periods of time, whereas weather is the term for day-to-day temperature, precipitation, and other atmospheric factors. Without more explanation, "weather" is typically taken to refer to the weather on Earth.

Differences in air pressure, temperature, and moisture from one location to another influence the weather. The Sun's angle at any given location, which changes with latitude, may be the cause of these variations.

Hence option A is correct.

The ship travels with a velocity of 15 km/h within 2 hours. The distance travelled is the velocity times the time taken that is 30 km to the north.

Velocity is a physical quantity measuring the distance travelled by an object per unit time. Velocity is the rate of speed and it is a vector quantity having both magnitude and direction. The unit of velocity can be m/s, km/h, ft/s etc.

Velocity is the ratio of the change in distance to the change in time. The change in distance is sometimes called the displacement.

then velocity  = displacement / time

Given that velocity = 15 km/h

time taken = 2 hours

then displacement = velocity × time

= 15 × 2 = 30 Km

Therefore, the displacement of the ship is 30 km to the north.

e friend sitting on the swing = 50 kg

Rate of acceleration = 4 m/s^2

The above information's are already given in the question. We need to utilize these information's in such a manner that the answer to the question can be determined easily.

We already know that

Force = Mass * acceleration.

This formula has to be used to find the force exerted.

Then

Force exerted = Mass of the friend * Acceleration

                      = (50 * 4) kg m/s^2

                      = 200 Newton

So the force exerted by me is 200 Newton. I hope the explanation and the procedure is clear to you and you are satisfied with it.

1st determine you subject slade to you have a mass of 15 kg being subjected to a force of 180N

so.

180N/15kg=180(kg m)/s^2/15kg=12 ms^2

now determine how long u pushed it

d=0.5 A T^2

sutable the known values getting

2.5 m = 0.5 12 ms^2 T^2

2.5m= 0.6 ms^2 T^2

0.41667 s^2=T^2

0.645497224s=T

the velocity multiply the time by the acceleration giving

0.645497224 s 12 ms^2 =7.745966692 ms.

after rounding the 2 significant u get 7.7 ms
