a circuit has 2.25 amps of current and a resistance of 4.00. what is the voltage difference across the circuit?

Answers

Answer 1

Answer:

2.25

Explanation:

2.25 - 4.00

2-4=2

25-00=25

= 2.25

2.25 - 4.00 = 2.25 because 2-4=2 and 25-00=25=2.25

Answer 2

The voltage difference across the circuit is equal to 9 V when 2.25 A current flows through the circuit.

What is Ohm's law?

Ohm’s law states that the voltage difference across any conductor is directly proportional to the current flowing through that conductor. Assuming temperature and all the physical conditions remain constant.

Ohm’s law can valid only if the temperature remains constant. Ohm’s SI unit is rho (Ω), and the current raises the temperature.

The mathematical formula of potential difference provided by Ohm/s law is:

V = IR

Where V is the potential difference and R is the resistance and I the current flowing.

Given, the resistance of the circuit, R = 4 ohm

The current flowing through the circuit, I = 2.25 A

The potential or voltage difference across the circuit will be:

V = I × R

V = 2.25 × 4

V = 9 Volt

Therefore, the potential difference across the circuit is equal to 9 V.

Answers

The Magnitude of force on the charged particle is -

F = (12.8 x 10⁻¹⁹C)i - (3.2 x 10⁻¹⁹C)j - (6.4 x 10⁻¹⁹C)k

We have a positively charged particle that moves through a region where both a uniform magnetic field and a uniform electric field exist.

What is Lorentz Force?

The force exerted on a charged particle (q) moving with velocity (v) through an Electric field (E) and Magnetic field (B) is called Lorentz force.

Mathematically -

|F| = qE + qv x B

According to the question, we have -

q = 3.20 × 10⁻¹⁹C

v = (2i + 3j - k) m/s

B = (2i + 4j + k) T

E = (4i - j - 2k) V

Now, using the formula to calculate Lorentz force -

F = q(4i - j - 2k) + q(2i + 3j - k) x (2i + 4j + k)

F = q(4i - j - 2k) + (2qi + 3qj - qk) x ((2i + 4j + k)

F = q(4i - j - 2k) + 0

F = q(4i - j - 2k)

F = (12.8 x 10⁻¹⁹C)i - (3.2 x 10⁻¹⁹C)j - (6.4 x 10⁻¹⁹C)k

The vector measure of level and direction of motion is known as velocity. The speed at which an object goes in one direction is known as its velocity. Speed may be used to calculate both the speed of the car traveling north on the major highway and the speed of the rocket bursting in space. As you may expect, the vector velocity's scalar size (total value) corresponds to the movement's speed. Speed is the initial exit of a place in terms of time when it comes to computations.

A Smart Car, which has a mass of 1000 kg, is going 20 m/s. When it hits the barrier, it stops at a time of 0.5 seconds. What is the force on the car?

Answers

Answer:

The force = F =  -40000 N

Explanation:

Mass m = 1000 kg speed v₁ = 20 m/s speed v₂ = 0 m/s t = 0.5

We know that,

Calculating the acceleration

using the formula

a = (v₂ - v₁) / t

   = 0 - 20 / 0.5

  = -20 / 0.5

   = -40 ms⁻²

Thus, acceleration (deceleration) = a = -40 ms⁻²    

Note: negative sign gives us an idea the car is slowing down after a collision with the barrier, thus acceleration and velocity are in opposite direction.

We know that

F = ma

   = 1000 × -40

   = -40000 N

Thus, the force = F = -40000 N

as you walk to the grocery store you walk 800m north, 600m east and 200m south at a speed of 1m/s. what is your velocity?

Answers

According to the question as you walk to the grocery store you walk 800m north, 600m east, and 200m south at a speed of 1m/s. Then your velocity will be ( V = 0.5m/sec )

Velocity is the directional pace of an object in movement as an indication of its price of alternate in function as located from a specific body of reference and as measured by a particular widespread of time.

To find the velocity follow the following steps:

Displacement of 800m north, 600m east, and 200m south from the Cartesian coordination is given as 600[tex]\sqrt{2}[/tex]

Velocity = displacement / time

Therefore time = distance / speed

Time = 800 + 600 + 200 / 1

Time = 1600s

Therefore velocity = 600[tex]\sqrt{2}[/tex] / 1600

Velocity = 0.5m/sec

Electrostatic induction is the change in a material's electric charge under the influence of another nearby object that has electric charge. For Electrostatic induction to occur a charged particle is held close (without touching it ) to a uncharged material that is grounded .

So, when the negatively charged rubber rod is brought closer to the grounded conductor which is neutral, a positive charge is induced on the conductor's side which is closer to the rubber rod and a negative charge on the other side which is close to the ground. So the negative charge starts escaping through ground. As it is disconnected from the ground, the conductor becomes positively charged.

The change that would occur if Earth's rate of rotation significantly increased is that the day would be shorter. The correct option is b.

What is Earth's rotation?

The rotation or spin of the Earth is the rotation of the planet Earth around its own axis, as well as changes in the orientation of the rotation axis in space. Earth rotates counterclockwise as seen from the northern polar star Polaris.

Earth rotates because the sun attracts the earth and thus pulls it towards it, and because the earth's revolution around the sun causes it to move away from the sun in the direction of the tangent, causing a rotational force (torque) to act on the earth, causing it to rotate.

The Earth rotates once every 24 hours in relation to the Sun, but once every 23 hours, 56 minutes, and 4 seconds in relation to other distant stars. Because the Earth's rotation slows slightly over time, a day used to be shorter.

Thus, the correct option is b.

Answers

The back end of the rod moved [tex]1.90\ \mathrm{mm}$[/tex] in this time interval.

Given:

Young's modulus, Y = [tex]20 \times 10^{10}\;N/m^{2}[/tex]

Steel density, [tex]\rho = 7.86 \times 10^{3}\;kg/m^{3}[/tex]

Length of the rod, L = 80 cm = 0.800m

The speed of the wave in the rod is

[tex]$v = \sqrt{\frac{Y}{\rho}} = \sqrt{\frac{20\times 10^{10}\ \mathrm{N/m^2}}{7.86\times 10^3\ \mathrm{kg/m^3}}} = 5044\ \mathrm{m/s}$[/tex]

Hence the time taken by the wave to travel the end of the rod is,

[tex]$t=\frac{L}{v} = \frac{0.800\ \mathrm{m}}{5044\ \mathrm{m/s}} = 1.58\times 10^{-4}\ \mathrm{s}$[/tex]

The velocity of the rod is [tex]$v_r = 12.0\ \mathrm{m/s}$[/tex]

The other end will keep moving after the front end hits the wall until the wave reaches the other end, given the period determined by the above problem.

As a result, before the wave reaches the end of the rod, it has traveled a distance of

[tex]$\Delta L = v_r t = (12.0\ \mathrm{m/s}) (1.58\times\ \mathrm{s}) = 1.90\times 10^{-3}\ \mathrm{m} = 1.90\ \mathrm{mm}$[/tex]

The acceleration of the puck is 43.75 m/s².

The velocity of an object or particle in uniform motion is defined as the rate at which its direction is changing as seen from a particular angle and as measured by a particular unit of time.

The player's puck accelerates from a velocity of 5 m/s to 30 m/s in the same direction.

The player's puck covers a distance of 10 m during that process.

Therefore,

The initial velocity of the puck is u = 5 m/s

The final velocity of the puck is v = 30 m/s

The distance covered during the period is s = 10 m

Using the equation of motion,

v² - u² = 2as

(30)² - (5)² = 2 × a × 10

Explanation:

QC Two waves simultaneously present on a long string have a phase difference π between them so that a standing wave formed from their combination is described by
y(x,t) = 2Asin( kx + π/2 ) cos( ωt - π/2) (a) Despite the presence of the phase angle π, is it still true that the nodes are one-half wavelength apart? Explain.

Answers

The equation of motion of the standing wave, y(x, t) = 2•A•sin(k•x + π/2)•cos(w•t - π/2), indicates that it is still true that the nodes are one half the wavelength apart

Therefore;

It is still true that the nodes are one half the wavelength apart

What are the nature of standing wave?

The equation describing the standing wave formed by the two waves is y(x, t) = 2•A•sin(k•x + π/2)•cos(w•t - π/2)

A standing wave is formed when two waves that have equal amplitude and frequency and moving in opposite directions, are combined.

A standing wave can be formed by a wave and its reflection, resulting in a wave where there is no propagation of particles beyond the vibration region.

The fundamental frequency of a standing wave consists of two nodes and an antinode.

The wavelength is the distance between two peaks of one wave, such that two nodes are formed within the span of a wavelength, which makes the distance between nodes being half the wavelength of the wave.

Therefore;

It is still true that the nodes are one half the wavelength apart.
