The expression that relates emf, potential, current, and resistance is Ohm's law.True or
False

Answers

Answer:

This expression is True

Since the Ohm's Law "states that the current )I) through a material between two points is proportional to the voltage across the two points." and i defined by this formula:

$V = IR$

Where V represent the voltage and it's a value related to the emf and the potential

I represent the current

R represent the resistance.

And for this case we have an expression for this case relating the emf , potential, current and resistance

Explanation:

This expression is True

Since the Ohm's Law "states that the current )I) through a material between two points is proportional to the voltage across the two points." and i defined by this formula:

$V = IR$

Where V represent the voltage and it's a value related to the emf and the potential

I represent the current

R represent the resistance.

And for this case we have an expression for this case relating the emf , potential, current and resistance

Ohms law:
V = IR The relationship between electrical resistance, current, and voltage is defined by the mathematical relationship V= IR and is referred to as Ohm's law. In this equation "V" stands for voltage, measured in volts, "I" stands for current, measured in amperes, and "R" stands for resistance, measured in Ohms (Ω ).Common sources of voltage in circuits may be chemical cells (a battery is a combinations of cells) and generators. Sources of electrical resistance in circuits may include resistors, light bulb filaments, wire conductors and other electric devices. When solving Ohm's law problems you are expected to solve for any unknown variable.
Example: Determine the voltage of the circuit shown below in diagram "A".Diagram A In this circuit we are given the current from the ammeter .2A. We also can determine the resistance. Since this is a series circuit the total resistance is the sum of the resistances of L1 and L2, 70Ω . We set the problem up and solve it like this.
V=IR
V=.2A 70Ω
V= 14VThe answer is 14V

What is the velocity of a plane that traveled 3,000 miles from New York to California in 4.5 hours

Answers

Answer:

v = 666.67 mph

Explanation:

It is given that,

Distance from New York to California is 3000 miles

Time taken fromNew York to California is 4.5 hours

We need to find the velocity of a plane. Velocity is equal to the distance over time. So,

$v=(d)/(t)\n\nv=\frac{3000\ \text{miles}}{4.5\ \text{hour}}\n\nv=666.67\ \text{mph}$

So, the velocity of the plane is 666.67 mph.

What type of energy is involved when a river moves sediment and erodes its banks?a. chemical energy
b. gravitational energy
c. potential energy
d. kinetic energy

What happens as gravity pulls water down a slope?
a. Kinetic energy changes to potential energy.
b. Both kinetic and potential energy vanish.
c. Energy is stored for future use.
d. Potential energy changes to kinetic energy.

Answers

First question: The type of energy involved when a river moves sediment and erodes its banks is: option d. Kinetic energy. Kinetic energy is the energy associated with motion. A body (in this case the water) that moves has an energy associated with its motion that is proportional to the speed (exactly to the square of the speed). When the water collides with the banks it is the kinetic energy of the river that erodes it Second question: the answer is the option d. As gravity pulls water down a slope potential energy changes to knietic energy. This is the, water loses altitude and gains velocity. The potential energy. which is proportional to the height, decreases and the kinetic energy, which is proportional to the square of the speed, increases.

Answer:

Question A: D., or "kinetic energy".

Question B: D., or "Potential Energy changes to kinetic energy."

a block of mass 5kg slides down an inclined plane that has an angle of 10 degrees if the inclined plane has no friction and the block starts at a height of 0.8m how much kinetic energy does the block have when it reaches the bottom? acceleration due to gravity is 9.8m/s2. someone help me how to solve this, physics conservation of energy

Answers

The physics conservation of energy E = 39.2 joules.

To calculate the Physics conservation of energy.

Mass of the block, m = 5 kg

At the top, the block will have only potential energy which is given by :

P=mgh

At the bottom of the inclined plane, it will have only kinetic energy which is given by :

E=(1/2)mv2

Applying the conservation of energy as :

E=(1/2)mv2=mgh

E=5*9.8*0.8

E = 39.2 joules.

The physics conservation of energy E = 39.2 joules.

To learn more about The physics conservation of energy refer:brainly.com/question/4301920

#SPJ2

In this case, the inclined plane is frictionless and therefore energy is perfectly conserved with no losses. The block originally starts off with some gravitational potential energy, which is then completely converted into kinetic energy. So the initial gravitational potential energy is equal to the final kinetic energy.

$PE_(initial) = KE_(final)$
$PE_(initial) =mgh=(5kg)(9.8m/ s^(2) )(0.8m)=39.2 joules$
$KE_(final)=39.2joules$

Explain why dissolving is a physical change

Answers

It's a physical change because it is changing from one matter to another.

because the kinetic energy start to decrease, for example if we put sugar in a high temperature tea and we shake it what will happen to the sugar will the kinetic energy increase or decrease, it will probably decrease, just like us the people when we enter a cold room and we have a hot temp.
