What is the potential difference across the source?
60 V
220 V
440 V
120 V

Answer:

1/3 m/s

Explanation:

Because the graph goes from 3 to 8 on the Y axis we know that each line is 0.5   and on the X axis each line is  1,   Then,  the slope , or velocity, is 1/3

see?   This graph is kinda set up to throw  you.  

Is there a  1/3 option for this ??

Hi there!

Recall the equation for magnetic force on a moving particle.

[tex]F_B = qv \times B[/tex]

[tex]F_B[/tex] = Magnetic Force (N)
q = Charge of particle (C)

v = Velocity of particle (m/s)
B = Magnetic Field Strength (T)

**This is a cross product, so the equation can be written as [tex]F_B[/tex] = qvBsinφ where φ is the angle between the velocity vector and magnetic field vector.

Since the proton is traveling perpendicular to the field, we can disregard the cross product. (sin90 = 1.)

Rearrange the equation to solve for 'B':

[tex]B = \frac{F_B}{qv}\\\\B = \frac{1.15 * 10^{-13}}{(1.6 * 10^{-19})(3.0 * 10^6)} = \boxed{0.24 T}[/tex]

Answer:

Your neighbor does twice as much work.

Explanation:

Distance(measurement) * exertion(force of pushing mower) = work

6 * 1/3 = 2

Your neighbor does twice as much work as you do.

Answer:

your answer should be astronomy

Explanation:

Answer:

Work = force x displacement

Force = W/s = 9/7 = 1.28 N

Answer:

the nucleus of an atom is held together by a strong nucleus force that binds together protons and neutrons.all though the strong nucleus force is stronger than the four fundamental forces.it acts over very short typically nucleus substances

Answer:

False

that should be 5m

Explanation:

So

Answer:

If you have an initial velocity of 1.5m/s and the ramp height is 4.5, and an extreme fart is initiated at the bottom of the ramp exerting an didditional upward force, and the smell of the fart causes you to begin flailing, and everyone running from you causes an additional wind force, then you would be rolling at a speed of 3 m/s given there is no friction. :)

The latent heat of fusion for water is 334 joules per gram.

Explanation: im smart

Answer:

Carbon Dioxide is supposed to block out radiation and is can be used in plant to make material, include cement,plastic,and rubber. However, since carbon dioxide is a greenhouse gas, it warms the Earth,and causes the climate to change.

The magnitude of the sum of the two vectors is 20.22 m and the direction of the two vectors, A + B is 50⁰.

The magnitude of the sum of the two vectors is calculated as follows;

Bx = Bcosθ

By = Bsinθ

Bx = 15 m x cos(30) = 12.99 m

By = 15 x sin(30) = 7.5 m

Ax = 8 m x cos(90) = 0 m

Ay = 8 x sin(90) = 8 m

Ax + Bx = 0 + 12.99 m = 12.99 m

Ay + By = 8m + 7.5 m = 15.5 m

R = √12.99² + 15.5²

R = 20.22 m

tanθ = 15.5/12.99

tanθ = 1.19

θ = 50⁰

Answer:

In a solar eclipse, the sun is completely blocked because the moon moves between the earth and the sun. Although the moon is much smaller than the sun because it is located so far away from the earth, the moon can completely block sunlight from the earth's point of view.

Explanation:

velocity = wavelength × frequency

3×10⁸ = 400/10⁹ × frequency

frequency = 3 × 10¹⁵ /400

frequency = 75×10¹¹Hz

Answer:

True: For a sound wave to propagate, air particles must be displaced in the direction of propagation - it is the displacement of these particles that causes the eardrum to vibrate and recognize the sound.

Answer:

Work=Force×distance

Explanation:

work=force×distance

Remember unit of work is Joules or Newton metre(N/m).

Answer:

When accounting for threats to validity in their study design, researchers must make assumptions about their environment. If any of these assumptions prove to be false, then it is more difficult to properly interpret the results of the experiment.

Hi there!

1)

We can use the following equation to solve for resistivity.

[tex]R = \frac{\rho L}{A}[/tex]

R = Resistance (30 Ω)

ρ = Resistivity (? Ωm)

L = Length (100cm = 1 m)
A = Cross-sectional area of wire (r = 0.15m, A = πr², A = 0.0707 m²)

Rearrange the equation to solve for resistivity.

[tex]\rho = \frac{RA}{L}\\\\\rho = \frac{30 * 0.0707}{1} = \boxed{2.121 \Omega m}[/tex]

2)
The conductivity of a resistor is equivalent to:
[tex]\sigma = \frac{1}{\rho}[/tex]

σ = Conductivity (S/m)

ρ = Resistivity (2.121 Ωm)

Solve:
[tex]\sigma = \frac{1}{2.121} =\boxed{0.472 \frac{S}{m}}[/tex]

3)
We can use the equation for resistivity to solve. Rearrange the equation for length:
[tex]R = \frac{\rho L}{A}\\\\L = \frac{AR}{\rho}\\\\L = \frac{0.0707 * 5}{2.121} = \boxed{0.167 m}[/tex]

Answer:   The piezoelectric effect describes the property of certain solids to generate an electrical charge under mechanical stress. The actuating force modifies the microscopic structure of the body; dipoles are created between which a voltage builds up. And Their positive and negative charges complement each other creating two types of electricity: static electricity
