If temperature is constant, the volume of a gas varies inversely as its pressure. The constant of proportionality for this variation is 3750.

Temperature is the degree of hotness or coldness of the object.

According to the ideal gas law, pV =nRT

where, p=pressure of gas, V =volume of gas, n=number of moles of element of gas, R=Universal Gas constant and T =temperature

When the temperature is constant,

PV =constant =k

k = 150x 25

k = 3750

Thus , the constant of proportionality is 3750.

answer:

The time required by the 1 KW heater to raise the temperature of 10 L of water is 418.4 s

Q = MCΔT

Q = Pt

Pt = MCΔT

Divide both sides by P

t = MCΔT / P

t = (10000 × 4.184 × 10) / 1000

t = 418.4 s

Answer:

The weight of an object is dependent upon the value of the acceleration of gravity.

Answer:

B. Negative acceleration means this car is slowing down.

Explanation:

for the other screenshot

Average acceleration = change in velocity /change in time.

[a = ∆V/∆t] —this the formula.

NOTE:

u = initial velocity (velocity it started with)

v = final velocity (velocity it ended with)

t = time {the time you were given)

a = acceleration.

listing out our givens:

u =o —(the unit is m/s)

v = 40 —(the unit is also m/s)

t = 0.08 —(the unit is s) "s" means second(s).

Soo

a = 40-0 / 0.08 = 500 m/s² ( unit for velocity is m/s²)

( Remember when using the formula we subtract the initial from the final velocity.........I mean we remove the initial from final) if not you will get a negative answer or wrong answer).

also note: final velocity is always bigger in value than initial velocity EXCEPT it is in deceleration meaning for example a car that was speeding is gradually stopping then initial (the one it started with) will be bigger than the one it ended with (because as it gradually stops the speed reduces).

VELOCITY is speed in a specified direction.

The 2.7 x 10^17 J of energy is produced when 3.0 kg mass disappears.

According to Einstein's equation, the energy produced when mass is converted to energy is proportional to the mass of the substance.

The Einstein equation is given as:

[tex]E = mc^{2}[/tex]

Mass = 3 kg

c = 3.0 × 10^8

[tex]E = 3 × (3.0 × 10^{8})^{2} = 2.7 \times 10^{17}[/tex]

Therefore, 2.7 x 10^17 J of energy is produced when 3.0 kg mass disappears.

If you touch a conductor through which electricity flows with an insulator, the likelihood of receiving a shock depends on several factors, including the voltage and current of the electrical source, the amount of insulation present, and how well the insulation is able to insulate from the electricity.

Insulators are materials that do not conduct electricity and are commonly used to provide a barrier between humans and electrical conductors to prevent electrical accidents. When an insulator is used to touch a conductor through which electricity flows, the insulator acts as a barrier and prevents the current from flowing through the material and into the body.

However, if the insulation is inadequate or damaged, or the voltage of the electrical source is high enough to overcome the insulating properties of the material, a shock can occur. The shock occurs when the current passes through the body, causing damage to organs, muscles, and nerves.

Therefore, it is important to ensure that proper insulation practices are followed when working with electrical conductors, and to use insulation materials that are sufficient to protect against the voltage and current levels of the electrical source being used. Generally, it is recommended to avoid touching electrical conductors altogether, as the risk of electrical accidents is always present.

No, you will not receive a shock if you touch a conductor through which electricity flows with an insulator. An insulator is a material that does not conduct electricity, meaning it does not allow the flow of electric current.

It has high resistance and acts as a barrier, preventing the transfer of electrons. Therefore, when you touch a conductor with an insulator, the insulator acts as a protective layer that blocks the flow of electric current and prevents it from reaching your body. As a result, you will not experience a shock. However, it is important to note that the effectiveness of the insulator in preventing a shock depends on its quality and condition. If the insulator is damaged or has a low resistance, it may not provide adequate protection, and there is a risk of electric shock. Additionally, it is crucial to follow safety protocols and avoid touching conductors or working with electricity unless you are trained and have the necessary knowledge and equipment to do so safely.

Explanation:

The integral of a velocity versus time function is a displacement versus time function

So we integrate,

[tex] {t}^{2} - t[/tex]

The integral of that is

[tex] \frac{1}{3} {t}^{3} - \frac{ {t}^{2} }{2} [/tex]

Plug in 12 for t,

[tex] \frac{1}{3} (12 {}^{3} ) - \frac{12 {}^{2} }{2} [/tex]

[tex]576 - 72 = 504[/tex]

So the displacement is 504 meters to the right.

vf = 12² - 12 = 132 m/s

a = vf' = 2t-1

at t =12 s,

a = 2(12)-1 = 23 m/s²

vf²=vi²+2ad (vi=initial velocity=0)

vf²=2ad

132² = 2 x 23 x d

d = 378.78 m
