A projectile is launched horizontally from a raised platform. If air resistance is ignored, then as the projectile falls to the

earth, the magnitude of the vertical component of the velocity of the projectile:a. increases, while the horizontal component decreases.
b. increases, while the horizontal component remains constant.

<h2>The option ( b ) is appropriate answer </h2>

Explanation:

When a projectile is projected from height horizontally . The only force acting upon it is the downwards gravitational force of attraction due to earth .

Due to this force its vertical component of velocity , which is in the downward direction will be increased .

As there is no force horizontally , the horizontal  velocity of throw will remain constant .

Thus ( b ) option is the correct option .

A camera phone called the iPhone X has an image sensor size of 5 mm and a focal length of 4 mm. How long of a selfie-stick must
azamat

Answer:

length of selfie-stick is 1.62 m

Explanation:

Given data

image size h1 = 5 mm = 5 ×10^{-3} m

focal length = 4 mm = 4 ×10^{-3} m

distance h2 = 2.032 m

to find out

How long of a selfie-stick

solution

here we find first magnification

that is M = h1 /h2

M = 5 ×10^{-3} / 2.032

M = 2.46 ×10^{-3}

and we know M = p/q

so p = Mq = 2.46 ×10^{-3} q

so we apply lens formula

1/f = 1/p - 1/q

1/ 4 ×10^{-3} = 1 / 2.46 ×10^{-3}  q - 1/q

q = 1.622 m

so length of selfie-stick is 1.62 m
