Using a material that is ‘Ohmic’ (it follows Ohm’s Law), you make a circuit using wire, a battery, and a resistor. After measuring V, I, and R across the circuit, you switch out the original resistor with one 3 times more resistive. When you measure V, I, and R again, how will the new values compare to the old?

Answers

When the original resistor is replaced with 3 times more resistive material, the resistance of the circuit increases by factor of 3 and  the current flowing in the cirucit decreases by a factor 3.

Ohm's law

Ohm's law states that, the current flowing in a conductor is directly proportional to the potential across the conductor.

V = IR

where;

I is the current in the circuitV is voltageR is the resistance

When the resistance increases, the current flowing in the circuit decreases.

an air track car with a mass off 0.25 kg and velocity of 3.4 m/s to the right collides and couples with a 0.45 kg car moving to the left with a velocity of 3.9 m/s. what is the combined velocity of the cars just after the collision?

Answers

Answer:

Two objects are moving in opposite direction on a straight line. After collision, they stick together and move with common velocity

The total momentum of a colliding system is constant always. Therefore, by using this concept, the final velocity of the coupled mass will be 3.7 m/s.

What is momentum ?

Momentum of an object is the ability of an object to bring the force applied to make a maximum displacement. It is the product of its mass and velocity. Momentum is a vector quantity. It have both magnitude and direction.

The momentum in a collision is conserved. Thus total initial momentum is equal to the final momentum. Let m1 and m2 be the colliding masses and the u and v be the initial and final velocity.

Then, m1 u1 + m2u2 = (m1 + m2)v for a coupled mass after collision.

then final velocity v =  ( m1 u1 + m2u2 )/ (m1 + m2)

Apply the given values in the equation as follows:

v = (0.25 kg ×3.4m/s + 0.45 kg× 3.9 m/s)) (0.45 + 0.25) = 3.7 m/s

Therefore, the final velocity of the coupled masses after collision is  3.7 m/s.

Answers

Answer:

Volt divided by ampere

Explanation:

V = IR

V/I = R

The unit of resistance from ohms law is volt / ampere. Thus, option A is correct.

What is Ohm's law?

Ohm's law states that the applied voltage is directly proportional to the current flow in the conductor. It is written as V ∝ I. It remains constant at room temperature.

V is defined as  potential difference or voltage. The SI unit of voltage is volt(V). I is defined as the current flowing in the circuit. The SI unit of current is ampere (A).

Generally, ohm's law equals to V = IR. R represents resistance of a material which oppose the current flow in the conductor. The unit of resistance is ohm(Ω).

When the potential difference(V) is constant, Resistance is inversely proportional to current. Current increases with decrease of resistance and current decreases with increase of resistance.

To find  equivalent unit of resistance, the ohm's law is :

V = IR

R = V / I

  = volt / ampere.

Hence, the unit of resistance from ohm's law is volt / ampere. The SI unit of resistance is ohm(Ω). Thus, option A is correct.

A rock with a mass of 10. 0kg falls 25. 0m to

the ground. What is the work done by the

gravitational force if the weight of the ball

is 98. 0N?

Answers

Answer:

Explanation:Potential Energy is the stored energy of an object given its position relative to a body. Gravitational potential energy is one type of potential energy and is equal to the product of the object's mass (m), the acceleration caused by gravity (g), and the object's height (h) as distance from the surface of the ground (the body).

mass m of 3 kilograms falling at gravity g of 9.81 meter per second squared from a height h of 5 meters. Solve for potential energy Pe with the equation PE equals m times g times h

In this example, a 3 kilogram mass, at a height of 5 meters, while acted on by Earth's gravity would have 147.15 Joules of potential energy, PE = 3kg * 9.81 m/s2 * 5m = 147.15 J.

9.81 meters per second squared (or more accurately 9.80665 m/s2) is widely accepted among scientists as a working average value for Earth's gravitational pull. This figure is based on a measure of gravity at sea level at a latitude of 45°.

At higher altitudes, gravity decreases slightly.

The effect of latitude on gravitational force is relevant as gravity increases with increasing distance from the Equator. At the Equator, the Earth's gravity is 9.780 m/s2 and at the poles it is 9.832 m/s2 (source: CRC Handbook of Chemistry and Physics).

Gravitational acceleration (to three significant figures) for other planets and bodies in the solar system is as follows:

 m/s2 gn*

Sun 274 27.9

Mercury 3.70 0.38

Venus 8.87 0.90
