Rotation describes the circular motion of an object around its center.
Explanation:
Answer:
A. a meteor traveling unhindered through space
Explanation:
The range of the projectile is 188 m
Explanation:
The motion of the arrow in this problem is a projectile motion, so it follows a parabolic path which consists of two independent motions:
- A uniform motion (constant velocity) along the horizontal direction
- An accelerated motion with constant acceleration (acceleration of gravity) in the vertical direction
The path of a projectile is the combination of these two motions: see figure in attachment.
In order to find the horizontal range of the projectile, we just need to calculate the horizontal distance travelled.
We have:
t = 5.0 s (time of fligth of the projectile)
and the horizontal velocity is constant, and it is given by

where
is the initial velocity
is the angle of projection
Substituting,

And therefore, the range of the projectile is:

A lightbulb carries more current immediately after it is turned on and the glow of the metal filament is increasing; option A.
<h3>What is current?</h3>
Current refers to the flow of electric charges typically electrons.
Current flowing through a metallic material decreases with increase in temperature of the material.
This is because the resistance of the metal increases with increase in temperature.
Therefore, for a light bulb, the current flow through it will be maximum when it is just turned on because the temperature, and hence the resistance of the filament is at its lowest.
In conclusion, current flow decreases with increase in resistance.
