Find the equation of directrix of the parabola is given by 64x equals to -ySquare

ANEK [815]

Answer:

Given equation of parabola is

and

=64x ......(i)

The point at which the tangent to the curve is parallel to the line is the nearest point on the curve.

On differentiating both sides of equation (i), we get

2 y

d y

=64

⇒

d y

and

Also, slope of the given line is −

∴−

and

⇒and=−24

From equation (i), (−24)

=64x⇒x=9

∴ the required point is (9,−24)

Which radioactive emission has the smallest (least) mass? Question options:

Tems11 [23]

Answer:

The answer is D. gamma rays

Explanation:

A radioactive atom can have three different types of emission:

alpha particles (α) = they have a mass of 4 amu and they have a very low penetrating power.

Beta particles (β) = they have 5x $10^{-4}$ amu and they have an intermediate penetrating power

Gamma rays (γ) = they are not particles basically just energy so its mass is ≈ 0 and its penetrating power is higher

For this reason Gamma emissions (γ) has the smallest mass value.
