Answer:
The angle is 25.34°.
Explanation:
Given that,
Wave length = 650 nm
Angle = 68.0°
We need to calculate the distance
For a diffraction grating



We need to calculate the angle
Using formula for angle




Hence, The angle is 25.34°.
Explanation:
Fnet = ma.
Assume that there is no resistance acting on the mass. Therefore a = 15N / 45kg = 0.33N/kg or 0.33m/s^2.
Answer:
As an object approaches the speed of light, its mass rises precipitously. If an object tries to travel 186,000 miles per second, its mass becomes infinite, and so does the energy required to move it. For this reason, no normal object can travel as fast or faster than the speed of light.
Explanation:
You've described two (2) axes of motion.
The third one would have been up-and-down.
