How will the boat be affected if it enters a part of the river where the current is moving south at 2 m/s?​

Answer:

They become the same exact tempature

Explanation:

Since they got connected it should be the same.

the temperature of the front pipe compare with the temperature of the back pipe before the pipes touch by using same temperature.

Temperature is the measure of hotness or coldness expressed in terms of any of several arbitrary scales and it indicate the direction in which heat energy will spontaneously flow from a hotter body to a colder body.

It is not the equivalent of the energy of a thermodynamic system like burning match is at a much higher temperature than an iceberg whereas the total heat energy contained in an iceberg.

Temperature which is similar to pressure or density known as intensive property  that is independent of the quantity of matter is considered as distinguished from extensive properties, such as mass or volume.

Answer:

The solution of the given query is explained below in the explanation portion.

Explanation:

Given value is:

Work,

⇒  [tex]W=4.30\times 10^3 \ J[/tex]

(a)

The change in the internal energy will be:

⇒  [tex]\Delta V=\frac{3}{2}nR(\Delta T)[/tex]

Throughout the isothermal procedure, The temperature will be constant "ΔT = 0".

then,

⇒  [tex]\Delta V = \frac{3}{2}nR(0)[/tex]

⇒  [tex]\Delta V = 0 \ J[/tex]

(b)

As we know,

⇒  [tex]\Delta V = Q-W[/tex]

On substituting the value, we get

⇒      [tex]0=Q-W[/tex]

On adding W both sides, we get

⇒    [tex]W=Q-W+W[/tex]

⇒    [tex]W=Q[/tex]

On substituting the given value of "W", we get

⇒     [tex]Q=4.30\times 10^3 \ J[/tex]    

Answer:

the answer is D

Explanation:

Answer:

Its False

Explanation:

In parallel circuits the current splits up so each branch has a different effective resistance (in each of the separate branches one can use the series rule again). Due to this, the current isn't the same everywhere in a parallel circuit.

Energy can be transferred from one storage mechanism to another.

Answer: C. -1.16 meters/second2

Explanation:

A= v/t (velocity/time)

in this case: v=7 and t=6

So, A= 7/6

A=1.16

The graph is decreasing so accelleration would be negative

A= -1.16 meters/second2

Explanation:

I'm not sure though

The power used when a 100 N force is applied to move an object through a distance of 5 m at constant speed in 10 seconds is 50 W

We'll begin by calculating the energy. This can be obtained as follow:

Force (F) = 100 N

Distance (s) = 5 m

E = F × s

E = 100 × 5

Finally, we shall determine the power. This can be obtained as follow:

Energy (E) = 500 J

Time (t) = 10 s

[tex]P = \frac{E}{t}\\\\P = \frac{500}{10}[/tex]

Therefore, the power used in moving the object is 50 W.

Answer:

gamma rays are super compact

Explanation:

as you move up the electromagnetic spectrum the wave lengths get shorter and shorter (higher and higher energy) gammas being the highest on the spectrum

Radio waves pass through us easily every day with no bad effects. Gamma Rays will kill you in large doses. the difference between these two forms of waves are in their energy.

Wave is is a disturbance in a medium that carries energy as well as momentum . wave is characterized by amplitude, wavelength and phase. Amplitude is the greatest distance that the particles are vibrating. especially a sound or radio wave, moves up and down. Amplitude is a measure of loudness of a sound wave. More amplitude means more loud is the sound wave.

Wavelength is the distance between two points on the wave which are in same phase. Phase is the position of a wave at a point at time t on a waveform.

There are two types of the wave longitudinal wave and transverse wave.

The energy of the electromagnetic photon is given by frequency times plank's constant. Hence energy is directly proportional to the requency. The frequency of the radio waves is far smaller than the gamma rays hence it has low energy. this is the difference, which leads gammas rays  injurious to heath.

Answer:

Workdone = 17482.36 Joules

Explanation:

Given the following data;

Force, F = 120 N

Angle, d = 28.0°

Distance, x = 165 m

To find the work done, we would use the following formula;

Workdone = FxCosd

Substituting into the formula, we have;

Workdone = 120*165*Cos(28)

Workdone = 19800 * 0.8830

Workdone = 17482.36 Joules

Answer:

1 ohm

Explanation:

since there are two identical resistors, one resistor will be

R = [tex]\frac{4}{2}[/tex] =2ohm [ proven as in series [tex]R_{e} = 2 + 2 = 4ohm[/tex] ]

to calculate the equivalent resistance when in parallel:

[tex]\frac{1}{R_{e} } = \frac{1}{R_{1} } + \frac{1}{R_{2}}[/tex]

so,

[tex]\frac{1}{R_{e} } = \frac{1}{2} + \frac{1}{2}[/tex]

[tex]R_{e} = 1ohm[/tex]

Two identical resistors connected in series have an equivalent resistance of 4 ohms. The same two resistors, when connected in parallel, have an equivalent resistance of 1 ohm.

In a parallel circuit, voltage is thee same across each component in the circuit. The sum of the currents through each path is equal to the current from the source. However, the resistance cannot be added directly. It is calculated as:

1/Rt = 1/R1 + 1/R2 + 1/R3 1/Rt = 1/6.8 + 1/9.0 + 1/15

Rt = 3.08 ohms.

When resistors are connected in parallel, the equivalent resistance R will be less than the least resistance.

1/R = 1/R1 + 1/R2 + 1/R3 + 1/R4 + 1/R5

Since the 5 resistors are 10 ohms each, substitute them in to the formula

1/R = 1/10 + 1/10 +1/10 + 1/10 + 1/10

The LCM = 10

1/R = 5/10

Reciprocate both sides

R = 10/5 = 2 ohms

Therefore, Two identical resistors connected in series have an equivalent resistance of 4 ohms. The same two resistors, when connected in parallel, have an equivalent resistance of 1 ohm.

I think its ion magnets correct me if I'm wrong

Answer:

Given that - R = 6 ohm

V = 3 volt

n = ?

so by ohms law , V = I X R

I = V \ R = 3 \ 6 = 0.5 A

we know that I = Q / T here t is 1 sec

Q = I X T = 0.5 X 1 = 0.5 C

By the law of quantization ,

Q = n x e

n = Q / e = 0.5 / 1.6 x 10 ^-19

n = 0.3125 x 10^19

Answer:

See Explanation

Explanation:

We know that;

P= IV

Where;

P = power

I= current

V = voltage

Here, we have a voltage of 220V

Hence, for maximum rate;

P= IV

I = P/V

P = 840 W

V= 220 V

I= 840 W/220 V

I= 3.8 A

V = IR

R = V/I

R = 220/3.8

R = 57.9 Ω

For minimum heating;

P= 360 W

V= 220 V

I = P/V

I = 360 W/220V

I= 1.6 A

V= IR

R = V/I

R = 220 V/1.6 A

R = 137.5 Ω
