Answer:

Ohm's law: I = V / R

Explanation:

V, I, and R, the parameters of Ohm's law

with

V = voltage in Volt

I = current in Ampere

R = resistance in Ohm

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points. Introducing the constant of proportionality.

The following equation is known as Ohm's law:

I = V / R

You can also write Ohm's law as

V = I * R

You can also write Ohm's law as

R = V / I

Ohm's law states that the R in this relation is constant, independent of the current

Calculate the temperature change when 1000J of heat is supplied to 100g of water.<br> Please explain

jasenka [17]

Answer:

It is sensible heat- the amount of heat absorbed by 1 kg of water when heated at a constant pressure from freezing point 0 degree Celsius to the temperature of formation of steam i.e. saturation temperature

So it is given as - mass× specific heat × rise in temperature

i.e. 4.2 × T

4.2 × (100–0)

So it is 420kj

If you ask how much quantity of heat is required to convert 1 kg of ice into vapour then you have to add latent heat of fusion that is 336 kj/kg and latent heat of vaporization 2257 kj/kg (these two process occur at constant temperature so need to add rise in tempeature)

So it will be

Q= 1×336 + 1× 4.18 ×100 + 1× 2257

Q = 3011 kj

Or 3.1 Mj

Hope you got this!!!!!!

How much heat is needed to increase the internal energy of a gas in a piston by 4,736J if the gas does 750J of work on the envir

kykrilka [37]

The heat absorbed by the gas is 5486 J

Explanation:

We can solve this problem by using the 1st law of thermodynamics, which states that the change in internal energy of a gas is given by:

$\Delta U = Q-W$

where:

$\Delta U$ is the change in internal energy

Q is the heat absorbed by the gas

W is the work done by the gas

In this problem, we have:

$\Delta U = +4736 J$ is the increase in internal energy of the gas

$W=+750 J$ is the work done by the gas (positive because the gas is doing work on the surroundings, by expanding)

Solving for Q, we find the heat needed:

$Q=\Delta U + W = 4736+750=5486 J$

And the positive sign tells us that this heat is absorbed by the gas.

PLEASE HELP!!! A.S.A.P.!!!!! WILL BE MARKED TO BE AS BRAINLEST!!! 30 POINTS!!!!!

Ray Of Light [21]

Answer: B)Number 1, 3 and 5 all demonstrate non-contact forces because the magnets or electrically charged objects exert forces on each other without touching.

Explanation:

Forces which act only when the two surfaces are in contact are known as contact forces. For example: frictional force is a contact force because it acts only when the two surfaces have tendency to move or are in relative motion.

Forces which act without any contact between surfaces are non-contact forces. For example: magnetic force, gravitational force, electrical force.

Because Kennedy and Lilly have to prove that some forces are non-contact forces, they must put up examples which actually show force being exerted between two objects without they being in contact. Thus, number 1, 3 and 5 demonstrate this.
