As the particles in a soup reach the boiling point what do you expect to happen

1 answer:

7 0

As the particles in a soup reach the boiling point, the kinetic energy of the molecules will start increasing and ultimately bubbles will be created in the soup and it will slowly start to vaporize. Boiling point of a liquid is the temperature at which the vapor pressure of the liquid will become equal to the atmospheric pressure.

Two parallel wires carry equal currents in the opposite directions. Point A is midway between the wires, and B is an equal dista

zepelin [54]

Answer:

Complete Question:(missing part)

The current in the left wire having magnitude is = 210 A

The Current in the right wire having magnitude is = 10 A

Answer:

a. $B net = \frac{\mu_{0} }{2\pi(\frac{d}{2}) } (I_{1} +I_{2} )$

Ratio = B 1/B 2 = 210/10 = 21

$b.B net = \frac{\mu_{0} }{2\pi(\frac{d}{2}) } (\frac{I_{1}}{3}-I_{1}} )$

Ratio = B 1/B 2 = 210/3 X10 = 7

Explanation:

Ratio of the magnitude of the magnetic field at point A to that at point B =?

The current in the left wire having magnitude is = 210 A

The Current in the right wire having magnitude is = 10 A

distance between two wires = d

Given that both wires are carrying equal current but in opposite direction therefore

Magnetic field linked with the left wire at point A distance =d/2= according to biot savarts law

$B = \frac{\mu_{0} \times I_{1} }{2\pi\times\frac{d}{2} }$

Magnetic field linked with the right wire at point B distance =d/2

$B = \frac{\mu_{0} \times I_{2} }{2\pi\times\frac{d}{2} }$

Net magnetic field added

B net = B 1 + B 2

$B net = \frac{\mu_{0} }{2\pi(\frac{d}{2}) } (I_{1} +I_{2} )$

Ratio = B 1/B 2 = 210/10 = 21

Magnetic field linked to left wire at point B(d+ d/2)

$B = \frac{\mu_{0} \times I_{1} }{2\pi\times\frac{3d}{2} }$

Magnetic field linked to right wire at point B(d+ d/2)

$B = \frac{\mu_{0} \times I_{2} }{2\pi\times\frac{3d}{2} }$

Net magnetic field subtracted

B net = B 1 - B 2

$B net = \frac{\mu_{0} }{2\pi(\frac{d}{2}) } (\frac{I_{1} }{3}-1 } )$

Ratio = B 1/B 2 = 210/3 X10 = 7

Which formulas might be used to find the velocity based on a position-time graph?

Alex787 [66]

The formula to get the velocity is V=D/T. First you need to determine the distance and time at a certain point and plug it into the equation and that will be your velocity at that point. To get it between two points you complete the directions two times and find the average or use the slope formula, slope = rise/run; slope = (y2 - y1) / (x2 - x1).

How is the kinetic energy of the particles that make up a substance different

never [62]

Answer:

Explanation:

The faster particles move, the more kinetic energy they have. Within a given substance, such as water, particles in the solid state have the least amount of kinetic energy. This is because they only vibrate in place. Particles in the liquid state move faster than particles in the solid state.

A ball is thrown vertically upward, which is the positive direction. a little later it returns to its point of release. the ball

PilotLPTM [1.2K]

This motion of all can be divided in to two, first the upward motion and second downward motion.

In case of projectiles time taken for upward motion = time taken for downward motion.

So we have time taken for upward motion = 8.14/2 = 4.07 seconds

We have equation of motion, v = u+at, where v is the final velocity , u is the initial velocity, a is the acceleration and t is the time taken.

In case of upward motion

v = 0 m/s

t = 4.07 seconds

a = -9.8 $m/s^2$

Substituting

$0 = u - 9.8*4.07\\ \\ u = 39.886 m/s$

So initial velocity of ball = 39.886 m/s.

If you were measuring a lower-pitched sound wave, you would measure _____.

Romashka-Z-Leto [24]

Answer: B

To measure a lower-pitched sound wave, you would measure fewer compressions per second. Pitch relates to frequency by measuring how many times a second the particles vibrate. Therefore, the lower-pitched sounds, the fewer compression waves or sound waves are produce because low-frequency sounds have greater distance between each wave.

Moreover, the frequency of a wave is measured as the number of complete back-and-forth vibrations of a particle of the medium per unit of time. The universal unit for frequency used is the Hertz (abbreviated Hz), where 1 Hertz = 1 vibration/second.
