Answer:
The greatest acceleration the man can give the airplane is 0.0059 m/s².
Explanation:
Given that,
Mass of man = 85 kg
Mass of airplane = 109000 kg
Distance = 9.08
Coefficient of static friction = 0.77
We need to calculate the greatest friction force
Using formula of friction

Where, m = mass of man
g = acceleration due to gravity
Put the value into the formula


We need to calculate the acceleration
Using formula of newton's second law


Put the value into the formula


Hence, The greatest acceleration the man can give the airplane is 0.0059 m/s².
A scientist can assess whether a pure niobium sample is responsible for contaminating the lab with radioactivity by testing the sample. By testing the niobium sample, a scientist can determine whether it has any other element.

Plato Answer
Answer:
The correct option is (c).
Explanation:
Given that,
The energy of a photon is, 
We need to tell the color of this light. We know that, the energy of a photon is given by :

Where
c is the speed of light

The wavelength of yellow light is approx 580 nm. Hence, we can say that this photon corresponds to yellow light.
