Answer:

<h2>Magnetic field strength in that region is 1.2 T</h2>

Explanation:

As we know by the formula of radius of charge moving in external field is given as

$R = \frac{mv}{qB}$

so we will have

$R = 25 cm$

$m = 1.6 \times 10^{-27} kg$

$q = 1.6 \times 10^{-19} C$

$v = 0.10 \times 3 \times 10^8 m/s$

now we have

$0.25 = \frac{(1.6 \times 10^{-27})(3\times 10^7)}{(1.6 \times 10^{-19})B}$

now we have

$B = 1.2 T$

lana66690 [7]

Answer:

-140

Explanation:

A gas loses 80joules of heat.

The gas also does 60 joules of work

Therefore the change in internal energy can be calculated as follows

= -80 + (-60)

= -80-60

= -140

Hence the change in internal energy is -140
