Answer:
the Glancing angle is the angle between the incident ray and plane mirror which is 90o in the given case. The angle between the direction of the incident ray and the reflected ray is the angle of deviation. Since the angle of deviation for a plane mirror is twice the glancing angle, the angle of deviation is 1800.
Answer:
Particles in a solid object are super tight and close to eachother. They do not move past eachother because it is a solid, not a liquid or gas.
Explanation:
Answer:
True, in as far as greater magnitude = greater power.

Answer:
The new pressure will be 0.225 kPa.
Explanation:
Applying combined gas law:
where,
are initial pressure and volume at initial temperature 
.
are final pressure and volume at initial temperature 
.
We are given:
Putting values in above equation, we get:
Hence, the new pressure will be 0.225 kPa.
