Answer:
Explanation:
<h3>Given Data:</h3>
Mass = m = 68 kg
Velocity = v = 30 m/s
Time = 2 hours = 2 × 60 × 60 = 7200 s
<h3>Required:</h3>
Force = F = ?
<h3>Formula to be used:</h3>
<h3>Solution:</h3>
The law of equal areas suggests that planets move fastest when at "perihelion" at slowest when at the "aphelion." Perihelion refers to the point at a planet's orbit, comet or asteroid where it is closest to the sun. Aphelion <span>refers to the point at a planet's orbit, comet or asteroid where it is furthest to the sun.</span>
D, as he is testing which type of fertiliser is the best, and hence it should be the only changed variable. Everything else should remain the same.
The frequency of the wave is 4 Hz
Explanation:
The relationship between wave, frequency and speed of a wave is given by the equation:
where
v is the speed of the wave
f is the frequency
is the wavelength
For the wave in this problem, we have:
is the speed
is the wavelength
Solving the equation for f, we find its frequency:
