What fossil images, there are no pictures attached.
The equation we use is mλ=dsinθ for intensity maximas. We are given at the first maximum (m=1), it occurs at 17.8 degrees. Thus we can solve for d by substituting known values into our equation.
(1) (632.8*10^-9m)=dsin(17.8) => d = 2.07*10^-6m
Next we want to find the angle at the second maximum (m=2) so we need to solve for θ.
(2) (632.8*10^-9m) = (2.07*10^-6m)sinθ
θ=37.69 degrees
Hopes this helps!
P.S. I hope this is right. If not sorry in advance.
Force is calculated F=m×a.
If both ships speed up with the same force, but have a different mass, This means that a also has to be different. If F is the same but ship a has a bigger mass(m) than ship b, then the acceleration(a) of ship b has to be bigger so F of each ship is the same. So the ship with the smaller mass will speed up faster.
Answer:
b-energy is not exchanged
Explanation:
An isolated system is a thermodynamic system in which neither energy nor matter is exchanged with the surroundings.
As such the best statement that will fill the box under an isolated system is that energy is not exchanged.
- In an open system, both matter and energy are exchanged with the surrounding.
- A closed system is one in which energy transfer is permissible but matter is not exchanged.
- Energy cannot be created nor destroyed in any system. They are simply transformed.
