Answer:

T_2 = 77.5c

Explanation:

From the question we are told that

Temp of first boltsT_1=100

Temp of 2nd bolt T_2=55

Generally the equation showing the relationship between  heat & temperature is given by

  q=cm \triangle T

Generally heat released  by the iron bolt  = heat gained by the iron bolt

Generally solving mathematically

     -(0.45*m* (T_2-100  \textdegree c)) = 0.45*m*(T_2 -55\textdegree c)

     -(T_2-100 \textdegree c)) = (T_2 -55 \textdegree c)

      T_2 +T_2= 100 \textdegree c+55 \textdegree c

      T_2=\frac{155 \textdegree c}{2}

      T_2 = 77.5 \textdegree c

Therefore T_2 = 77.5 \textdegree c is the final temperature inside the container

А
timurjin [86]

Answer:

i hope it will be useful for you

Explanation:

F=5.6×10^-10N

R=93cm=0.93m

let take m1 and m2 =m²

according to newton's law of universal gravitation

F=m1m2/r²

F=m²/r²

now we have to find masses

F×r²=m²

5.6×10^10N×0.93m=m²

5.208×10^-9=m²

taking square root on b.s

√5.208×10^-9=√m²

so the two masses are m1=7.2×10^-5

and m2=7.2×10^-5

- A straight wire, 0.20 m long, moves at a constant speed of 7.0 m/s
Elis [28]

(a) The emf induced in the wire is 0.112 V.

(b) The direction of the current will into the page.

(c) The polarity of A will be positive and L will be negative.

(d)  The current flowing through the wire is 0.224 A.

<h3>EMF induced in the wire</h3>

The emf induced in the wire is calculated as follows;

EMF = BLv

EMF = (8 x 10⁻²) x 0.2 x 7

EMF = 0.112 V

<h3>Direction of the current</h3>

Since, the magnetic field is out of the page, the current will follow counter clockwise and will point into the page.

<h3>Polarity of point A and point L</h3>

The current is flowing counter currently, hence the polarity of A will be positive and L will be negative.

<h3>Current through the wire</h3>

V = IR

I = V/R

I = (0.112)/0.5

I = 0.224 A

A train moving at a constant speed is passing a stationary observer on a platform. On one of the train cars, a flute player is c
ella [17]

Answer:

C) 21 m/s

Explanation:

The general formula of the Doppler effect is:

f'=(\frac{v+v_r}{v+v_s})f

where

f' is the apparent frequency

f is the original frequency

v is the speed of the wave in the medium

v_r is the velocity of the receiver, positive if the receiver is moving towards the source

v_s is the velocity of the source, positive if the source is moving away from the receiver

Here we have

f = 440 Hz

f' = 415 Hz

v = 343 m/s

v_r = 0 (the observer is stationary)

v_s is positive since we are considering when the train has passed the observer, so it is moving away from him

So we can rewrite the formula as

f'=(\frac{v}{v+v_s})f

And solving for v_s, we find the speed of the train

v_s = v(\frac{f}{f'}-1)=(343 m/s)(\frac{440 Hz}{415 Hz}-1)=20.7 m/s \sim 21 m/s
