<span>So we wonder how can we compare yellow and orange light. Light is a small art of electromagnetic spectrum which is a continuum of all electromagnetic waves arranged by wavelenght and frequency. So on the EM spectrum orange has greaterr wavelangth than yellow but smaller frequency because wavelength and frequency are connected by the equation: c=f*lambda, where lambda is the wavelength and c is the speed of light and f is the frequency. We see that the higher the frequency the smaller the wavelength and vice versa.</span>

Answer:
Explanation:
Weight is actually a force. A force can change depending on its location. A mass remains constant no matter where it is.
A)
F = m * a
m = 250 kg
a = 9.81 m/s^2
F = 250 * 9.81 = 2452.5 N
B)
The acceleration due to gravity on the moon is roughly 1/6 what it is on earth. You can check its value in your notes.
a = 9.81 + (1/6) = 1.635
m = 250
F = 250 * 1.635
F = 408.75
C)
The mass is the same anywhere in the universe.

Answer:
t = 7 sec.
Explanation:
As the car and the truck travel the same distance, assuming a constant acceleration, we can describe the movement of the truck and the car with these equations for this same displacement:
x(truck) = v*t (1)
x(car) = 
As the left sides of (1) and (2) are equal each other, the same must be true for the right sides:
v*t = 
Solving for t, replacing v= 10.5 m/s and a= 3 m/s², we have:
⇒ t = 7 sec.
