The maximum upward acceleration that the elevator can have without breaking is = 10.36m/s².
<h3>How to calculate maximum upward acceleration?</h3>To calculate the maximum acceleration of the elevator we must take into account Newton's second law and its formula that takes into account the following aspects:
- F = Is the force applied in newtons.
- m = Is the mass of the object in kilograms.
- a = Is the acceleration of the object in meters per second squeared.
- F = m × a
According to the above, we apply the values we have as follows:
- a =
- a =
- a = 10.36 m/s²

Answer:
D) directly, inversely
Explanation:
The energy of a photon of light is directly proportional to its frequency and inversely proportional to its wavelength.
Frequency is the number of waves that passes through a point per unit of time.
Wavelength is the is the distance between successive crests or troughs on a wave.
Mathematically, frequency is related to wavelength and velocity using;
Energy = h x f
where h is the Planck's constant
f is the frequency
Since c = f ∧
where f is the frequency of the wave
∧ is the wavelength of the wave
c is the speed of light
So;
f = c/∧
Therefore;
E =
From the equation, we see an inverse relationship between E and wavelength and a direct one with frequency.
