Answer:
Transverse wave- Back and forth at right angles to the direction of the wave arrow.
longitudinal wave- bask and forth in the direction of the motion of the motion of the wave.
electromagnetic wave- two alternating waves moving at right angles to each other.
Explanation:
In a longitudinal wave, the particles vibrate at right angles in reference to the wave motion.
In a transverse wave, the particles vibrate parallel to the wave motion
Electromagnetic waves occur as a result of the interaction between two waves and are normally transverse in nature.
1) temperature
2) pressure
3) concentration
4) surface area
5) the presence of a catalyst
Answer:
Initial velocity = 39.2m/s
Maximum height is 78.4m
Explanation:
Given
Solving (a): Initial Velocity
Using first law of motion:
Where
<em />
<em> [g represents acceleration due to gravity]</em>
Substitute these value in the above formula:
Take g as 9.8m/s²
<em>Hence, initial velocity = 39.2m/s</em>
Solving (b): Maximum Height
This will be solved using second equation of motion
This becomes
Substitute values for u, t and g
<em>Hence, the maximum height is 78.4m</em>
The magnet's north pole would point to the Earth's south pole. and the magnet's south pole would point to the Earth's north pole
