C. The downward component of the projectile's velocity continually increases

Explanation:

The motion of a projectile consists of two independent motions:  

- A uniform motion (with constant velocity) along the horizontal direction  

- A uniformly accelerated motion, with constant acceleration (equal to the acceleration of gravity) in the downward direction  

Here we want to study the downward component of the projectile's velocity. Since the vertical motion is a uniformly accelerated motion, the vertical velocity is given by:

v=u+at

where

u = 0 is the initial vertical velocity (zero since the projectile is fired horizontally)

a=g=9.8 m/s^2 downward is the acceleration of gravity

t is the time

So the equation becomes

v=gt

This means that

C. The downward component of the projectile's velocity continually increases

Because every second, it increases by 9.8 m/s in the downward direction.

The angle between magnetic north and the north to which a compass needle points is known as magnetic declination.
Romashka [77]

From among the choices provided, the better choice is the upper-case letter '<em>T </em>'.  That symbol can conveniently be used to represent the words "true" or "truth", which is exactly the reason that it is the better choice for a response, since the complicated statement at the beginning of the question is completely true in its every detail, nuance, jot and tittle.

How long can a flashlight run for if it draws 0.11 amps and its battery contains 10 coulombs of change?
Alex17521 [72]

Answer:

Battery will run for t = 90 s

Explanation:

As we know that rate of flow of charge is known as electric current

So we will have

i = \frac{Q}{t}

i = 0.11 A

Q = 10 C

now we have

t = \frac{Q}{i}

t = \frac{10}{0.11}

t = 90 s
