By using an electric field, it is feasible to differentiate between these different forms of radiation.

<h3>What is a radioactive source?</h3>

A source that emits radiation like gamma, beta, and alpha rays is said to be radioactive. Using an electric field, we can discriminate between these different forms of radiation.

The field does not deflate the gamma rays, but it does deflate the alpha and beta rays, with the alpha being deflated to the field's negative portion and the beta to its positive part.

Hence, by using an electric field, it is feasible to differentiate between these different forms of radiation.

Answer:

A. Part a is the attachment

B. total work = 10.4kj

Explanation:

workdone=nRT1ln\frac{Vb}{Va}

T1 = constant temperature

nRT1 = PaVa = PbVb

We write equation as

workdone =(PaVa)ln\frac{Vb}{Va}

5ma = Pa, 5L = Va, Vb = 10L(temperature is doubled)

w1 = workdone =(5mpa*5L)ln\frac{10L}{5L}

W1 = 25 ln2

W1 = 25 x 0.693

= 17.327kj

The isochoric expansion has no change in volume. So,

W2 = 0

Isothermal compression

w3=nRT3ln\frac{Vd}{Vc}

T3 = constant temperature

nRT3 = PcVc = PdVd

workdone=(PcVc)ln\frac{Vd}{Vc}

Pc = 1mpa Vc = 10L Vd = 5L

w3=(1)(10)ln\frac{5L}{10L}

= 10x-0.693

= -6.93kj

Isochoric compression has no change in volume. Workdone w4 = 0

Total workdone = w1 + w2 + w3 + w4

= 17.33 + 0 + (-6.93) + 0

= 10.4kj

Answer:

option B

Explanation:

When a body is immersed in liquid there will be two force is acting on the body.

First one force acting downward due to weight of the body.

And the second force acting on the object will be buoyant force.

If the object is not in equilibrium the apparent weight will be equal to net force acting on the object.

     F_{net} = W - F_b

W is the weight of the object acting downward

Fb is the buoyancy force acting upward on the object.

Hence, the correct answer is option B
