Answer 1

Answer:

Answer:

n/p ratio should increase and for that number of neutron should increase and proton should decrease.

oe¹+ 1P¹→ 1 n0. (K-electron capture)

1P ¹→ 1n0+ 1β0. (β+decay)

In both cases the number of neutron increase by 1 and proton decrease by 1.

option:- 3,4

Explanation:

i hope it will be the answer..

Answer 2

Explanation:

➥Malignant refers to cancer cells that can invade and kill nearby tissue and spread to other parts of your body.

Malignant tumors are cancerous growths. They are often resistant to treatment, may spread to other parts of the body and they sometimes recur after they were removed. A cancer is another word for a malignant tumor (a malignant neoplasm).ANSWER

If is increased from zero to , will first increase and then decrease.

x is maximum for .

The maximum value of is .

SOLUTION

The velocity of efflux

The emerging liquid moves as a projectile and reaches the ground in time , So we have

Differentiating w.r.t. to , we have

clearly

for

and

for

which implies that first increases and then decreases, as is increased from to option A is correct

for maxima or minima, we have

Since the is first increasing which implies that is a point of maxima. option B is correct

option C is correct.

It is clear from the above equation that is independent of density of the liquid.. option D is incorrect.
