sam can study for hours even though it is very loud and there are many possible distractions in the common room. this is an example of what?

The relative motion of the train next to her is the motion of the other train in her rest frame.

As the other train leaves, it seems to Sunita as if her train is moving backwards

Reason:

The motion of the train Sunita is taking is given by the rate of movement of

objects outside the train from the front side of the train towards the back

side of the train, that way she can tell that the train is moving.

The motion of the other train from the rear side of the train from the rear

side of the train to the front side is a reverse motion to what Sunita

observes when the train is moving forward. Therefore, as the other train

leaves, it seems to Sunita as if her train is moving backwards.

Answer: Elastic energy is the energy store in a.. compacted spring; an extended elastic band; and a drawn bow.  

Chemical potential energy​​ is position of electrons in specific substance bonds that can be broken (energizes).

:

This stored energy is released and performs work when the elastic material reverts back to its original position. ... In comparison, chemical potential energy, is the energy released during the formation of chemical compounds.

Answer:

If resistance is increased, the current decreases and if the resistance is decreased, the current flowing through the wire increases.

Explanation:

V = IR is ohm's law which implies I = V/R, where I is the current and V is the voltage and R is the resistance. Hence, I is inversely proportional to R.

Answer:

It must return at the same velocity with which it was thrown or else there would be a preferred direction of motion leading to perpetual motion.

a = (v2 - v1) / t = (v2 - 0) / 2 = v2 / 2    for a falling object

v2 = 2 a = 2 sec * 9.8 m/sec^2 = 19.6 m/s

You can check with

H = V0 t - 1/2 g t^2      (V0 and g are in different directions)

H = 0

V0 = 1/2 g * 4 = 19.6 m/s

Considering the change of units and rule of three, the number of tablets in the bottle is 2,000.

First of all, you know that each medicinal tablet has a mass of 250 mg, while the mass of all tablets is 0.5 kg. You can see that the measurements are in different units of measurement, so you must make a change of units so that they are in the same units.

So, knowing that 1 kg is equal to 1,000,000 mg, you can apply the following rule of three: if 1 kg is equal to 1,000,000 mg, 0.5 kg is equal to how many mg?

1 kg ⇒ 1,000,000 mg

0.5 kg ⇒ x mg

So: [tex]x=\frac{0.5 kgx1,000,000 mg}{1 kg}[/tex]

x= 500,000 mg

Then, you know that each medicinal tablet has a mass of 250 mg, while the mass of all tablets is 500,000 mg. Now that the values ​​are in the same units, to calculate the number of medicinal tablets you must apply the following rule of three: if 1 tablet has a mass of 250 mg, how many tablets have a mass of 500,000 mg?

[tex]number of medicinal tablets=\frac{500,000 mgx1 tablet}{250 mg}[/tex]

number of medicinal tablets= 2,000

Finally, the number of tablets in the bottle is 2,000.

B Both are directly related to movement.

Endocrine system and muscular system are directly related to movement while both stretching and constricting exercises are important for muscle health. So, the correct options for 1 and 2 are B and A respectively.

The endocrine system is defined as the communication system made up of feedback loops that send hormones released by an organism's internal glands into the circulatory system, controlling distant target organs. The neurological control center for all endocrine systems in vertebrates is the hypothalamus. The endocrine glands lack ducts that would transport their output to the surface. These are known as glands without ducts.

Growth and development, metabolism, and reproduction are just a few of the essential processes in the body that are regulated by the hormones the endocrine system secretes. Movement has a close relationship with the endocrine and muscle systems.

Therefore, the correct options for 1 and 2 are B and A respectively.

Answer:

Your kinetic energy is always proportional to the square of your speed,

no matter whether you're on a bicycle, a roller coaster, or a baby carriage.

The faster you're moving, the more kinetic energy you have.

Your potential energy doesn't depend on speed at all, only on height.

On a roller coaster, the minimum speeds are usually at the top of a hill

or a loop, so the potential energy would generally correspond to the

slowest speeds. But again, that's not because of the speed. It's because

of the height.

Answer:

Vf = 23 m/s

Explanation:

First we need to find the distance covered by the motorcycle 2 when it passes motorcycle 1. Using the uniform speed equation for motorcycle 1:

s₁ = v₁t₁

where,

s₁ = distance covered by motorcycle 1 = ?

v₁ = speed of motorcycle 1 = 6.5 m/s

t₁ = time = 10 s

Therefore,

s₁ = (6.5 m/s)(10 s)

s₁ = 65 m

Now, for the distance covered by motorcycle 2 at the meeting point. Since, the motorcycle started 50 m ahead of motorcycle 2. Therefore,

s₂ = s₁ + 50 m

s₂ = 65 m + 50 m

s₂ = 115 m

Now, using second equation of motion for motorcycle 2:

s₂ = Vi t + (1/2)at²

where,

Vi = initial velocity of motorcycle 2 = 0 m/s

Therefore,

115 m = (0 m/s)(10 s) + (1/2)(a)(10 s)²

a = 230 m/100 s²

a = 2.3 m/s²

Now, using 1st equation of motion:

Vf = Vi + at

Vf = 0 m/s + (2.3 m/s²)(10 s)

Vf = 23 m/s
