A mason is shot with a constant speed of 7.5 x 10²m/sinto a region, when an electric field produces acceleration on the mason of magnitude 1.5 x 1025 ms-2 directed opposite to the velocity. Find the time taken (b) the distance covered by the mason before coming to rest and (c) the time for which it remains at rest.​

Answers

Answer:

Distance, d = 0.1 m

It is given that,

Initial velocity of meson,

Finally, the meson is coming to rest v = 0

Acceleration of the meson,  (opposite to initial velocity)

Using third equation of motion as :

s is the distance the meson travelled before coming to rest.

So,

 

s = 0.1 m

The meson will cover the distance of 0.1 m before coming to rest. Hence, this is the required solution.  



6. An object has a volume 30ml and a mass of 30g. What is the density

Answers

Answer:

1 g/mL

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\[/tex]

From the question

mass = 30 g

volume = 30 mL

We have

[tex]density = \frac{30}{30} = 1 \\ [/tex]

Answers

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.

What is protein?

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.

Answers

Yes. Walking the hills in her neighborhood is a wonderful place to start.

D.  She can slowly improve her capacity and move to aerobic exercise later.

Yes, she can slowly improve her capacity and move to aerobic exercise later. The correct option is (D).

Even if it isn't initially aerobic, starting with walking is a wonderful place to start, especially if Bettina isn't used to exercising frequently. Walking is a low-impact activity that is simple to fit into daily life and can be used as a gentle introduction to developing a habit of physical activity.

Even while walking isn't typically thought of as an aerobic workout, it nevertheless has several health advantages, including enhancing cardiovascular health, boosting energy, lowering stress, and aiding in weight management. Bettina can eventually increase the length and intensity of her walks to make them aerobic as she steadily increases her endurance and fitness level through walking.

Hence, the correct option is (D). Yes, she can slowly improve her capacity and move to aerobic exercise later.

A flare fired upward at 49 m/s will reach a height of

Answers

Answer:

122.5 meters

Explanation:

We have the third equation of motion:

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

v stands for the final velocityu, initial velocitya is the acceleration of the particle in motionS, the distance covered by the same particle.

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:

v = 0 m/ su = 49m/ sa = - 9.8 m/ s (the force of gravity acts downwards, and that's the direction we say is negative)

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]

=> S = 122.5 meters

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

Answers

Explanation:

7.7 m/s

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

A ship travels north at 15 km/h for 2 h. What is the ship's displacement in km?

Answers

The ships displacement is 30 km north

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.

What is velocity ?

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.

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.

What is whether system ?

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.

You push a friends sitting on a swing. If you push with 200N of force and your friend accelerates at a rate of 4 m/s^2. Find the mass of your friend.

Answers

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.
