Answer:
Maximum acceleration will be equal to
Explanation:
We have given coefficient of kinetic friction
And coefficient of static friction
Acceleration due to gravity
When truck moves maximum force will be equal to
It is given that half of the weight is supported by its drive wheels
So force required
From newtons law maximum acceleration will be equal to
Answer:
Frequency =3.5×10^14hertz
Wavelength = 8.6×20^-7m
Explanation:
Energy of photon is expressed as;
E = hf where;
h is the Planck constant
f is the frequency of the photons
From the formula f = E/h
Given E = 2.32 × 10^ − 19 J
h = 6.63×10^-34Js
f = 2.32×10^-19/6.63×10^-34
f = 0.35×10^(-19+34)
f = 0.35 × 10^15
f = 3.5×10^14hertz
To get the wavelength, we will use the relationship:
f = c/λ
λ = c/f
Given c = 3×10^8m/s
f = 3.5×10^14hertz
λ = 3×10^8/3.5×10^14
λ = 0.86×10^-6m
λ = 8.6×20^-7m
Im not sure about controlled parameters, but i can explain how variables work. There are different types of variables. An independent one is the thing you change every time you do the experiment. Dependent variables are what you keep the same every time you do the experiment. (i hope this somewhat helped)
