Answer:
3.28 degree
Explanation:
We are given that
Distance between the ruled lines on a diffraction grating, d=1900nm=
Where 


We have to find the angular width of the gap between the first order spectrum and the second order spectrum.
We know that

Using the formula
m=1


Now, m=2





Hence, the angular width of the gap between the first order spectrum and the second order spectrum=3.28 degree
Answer:
Mass will be same on moon as on Earth but weight will be one-sixth of Earth.
Explanation:
Mass of a body doesn't depend on gravity. Mass is a constant quantity. So, mass on moon will be same as mass on Earth.
But, the weight of a body depends on gravity as weight is given as:

Therefore, if
is acceleration due to gravity on Earth, then weight on Earth is, 
Now, gravity on moon is one-sixth of Earth. So, 
Therefore, weight of the body on moon is, 
Therefore, a body has same mass both on moon and Earth but weight on moon is one-sixth of the weight on Earth.
Yes, it possible to code the impact force using an accelerometer.
Accelerometers can be used to measure vibration on cars, machines, buildings, process control systems and safety installations
<h3>What is an Accelerometer ?</h3>
An accelerometer is a device that measures the vibration, or acceleration of motion of a structure.
- The force caused by vibration or a change in motion (acceleration) causes the mass to "squeeze" the piezoelectric material which produces an electrical charge that is proportional to the force exerted upon it.
- They can also be used to measure seismic activity, inclination, machine vibration, dynamic distance and speed with or without the influence of gravity.

Answer:
Do not see a picture or graph but suspect it would show the golf ball falling faster and striking the ground slightly before the soccer ball.
Probably D: Soccer ball was affected by air resistance more than the golf ball.
Explanation:
Even though heavier, friction loss of the greater surface area soccer ball will counter pull of gravity more than the compact golf ball.
In a vacuum, (no friction) both objects fall at the same rate regardless of mass.
Weathering is where something is changed or mutilated by the weather. Erosion is hwere water or an other substance digs awaya at something and wears it out. I don't exactly know the last one or how to explain
