Question

If root(x) = t + 7 then which option is correct ?
(i) v directly proportional to t
(ii) v inversly proportional to t
(iii) v directly proportional to root(t)
(iv) a = constant

Answer 1

there is no reference to v or a in the equation

Answer 2

is 'x' intended to represent displacement?
v to be velocity
a to be acceleration?

Answer 3

yes

Answer 4

U know velocity
v=dx/dt

Answer 5

Acceleration a=dv/dt

Answer 6

Do u know hw to differentiate √x with respect to t

Answer 7

d√x/dt=?

Answer 8

no

Answer 9

Ok.

Answer 10

U know the formula
dx^3/dx=3*x^(3-1)=3x^2
Right?

Answer 11

Again dx^2/dx=2*x^(2-1)=2x
Right?

Answer 12

d√x/dx=dx^(1/2)/dx=(1/2)*x^(-1/2)*dx/dt=?
