Why is the horizontal component of a velocity remains constant in horizontal and inclined projection

Physics

Artemon [7]3 years ago

8 0

Answer:

This is because there is no acceleration in the horizontal direction

Explanation:

This is because, the only acceleration affecting the object in horizontal and inclined projection is the acceleration due to gravity, which is directed the vertical downward direction. There is a velocity change only in the vertical direction and none in the horizontal direction because, there is no acceleration in the horizontal direction. So, its velocity remains constant.

After a check up, a person now has a far point of 100 cm, but with good near point vision. He needs to wear a new pair of correc

lakkis [162]

Answer:

so his far point according to this pair of glass is 200 cm

Explanation:

power of old pair of corrective glasses is given as

$P = -0.5 dioptre$

now we have

$f = \frac{1}{P}$

$f = -2 m$

$f = -200 cm$

now we know that for normal vision the maximum distance of vision is for infinite distance

so by lens formula we have

$\frac{1}{d_i} + \frac{1}{d_o} = \frac{1}{f}$

$\frac{1}{d_i} + 0 = \frac{1}{200}$

$d_i = 200 cm$

so his far point according to this pair of glass is 200 cm

The charge stored in a parallel plate capacitor is proportional to the _____(potential, current) and across _____ (resistance, c

Aleksandr-060686 [28]

Answer:

The charge stored in a parallel plate capacitor is proportional to the potential, and capacitance across the plates.

Explanation:

The capacitance of a parallel plate capacitor is given by:

$C=\frac{Q}{V}$

where

Q is the charge stored

V is the potential difference across the capacitor

Re-arranging the formula, we get

$Q=CV$

From this expression, we see that the charge stored (Q) is proportional to both the potential (V) and the capacitance (C).
