When you kick a ball the when your foot hits the ball the force from your foot is now on the ball and if the ball bumps into somoene they might fall(if you kick hard)
<h3><u>Answer;</u></h3>
Eddy currents
<h3><u>Explanation</u>;</h3>
- <em><u>Eddy currents are currents which circulate in conductors like swirling eddies in a stream. These currents are induced by changing magnetic fields and flow in closed loops, perpendicular to the plane of the magnetic field. </u></em>
- They are created as a result of change in the intensity or direction of a magnetic field on a conductor, this occurs either when a conductor is moving through a magnetic field, or when the magnetic field surrounding a stationary conductor is varying
The seat belt is applying a force in the opposite direction.
In general, pitch increases more rapidly than frequency for tones below 1000 Hz and less rapidly for tones above 1000 Hz. That is, for frequencies above 1000 Hz a greater change in frequency is needed to produce a corresponding change in pitch.
The maximum height of the ball during this interval is 4.9 m (Option A)
<h3>How to determine the time to reach maximum height</h3>
The time taken to reach the maximum height can be obtained as follow:
- Time for the entire trip (T) = 2 s
- Time to reach maximum height (t) = ?
T = 2t
2 = 2t
Divide both side by 2
t = 2 / 2
t = 1 s
<h3>How to determine the maximum height reached by the ball</h3>
The maximum height reached by the ball can be obtained as follow:
- Acceleration due to gravity (g) = 9.8 m/s²
- Time to reach maximum height (t) =?
- Maximum height (h) =?
h = ½gt²
h = ½ × 9.8 × 1²
h = ½ × 9.8 × 1
h = 4.9 m
Thus, the maximum height reached by the ball is 4.9 m (Option A)
