Answer:
So, if a wave hits a mirror at an angle of 36°, it will be reflected at the same angle (36°). ... An incident ray of light hits a plane mirror at an angle and is reflected back off it. The angle of reflection is equal to the angle of incidence. Both angles are measured from the normal.

Answer:
15.825 m
Explanation:
t = Time taken = 2.5 s
u = Initial velocity = 6.75 m/s
v = Final velocity = 5.91 m/s
s = Displacement
a = Acceleration
Equation of motion
The distance Rickey slides across the ground before touching the base is 15.825 m
Ans. 5 X 10^6
Explanation:
Here,^ represents 6 times 10 and 5 is multiplied. That is 5000 000.
Hope this helps
Answer:
the answers, material D meets the requested characteristics
Explanation:
The objective of an insulating material for the house, must allow solar radiation to enter, so that the plants can perform photosynthesis and must prevent radiation from inside the house from being lost.
Therefore the material must meet two conditions be transparent to sunlight and be absorbed from the radiation coming from the house; this is to leave for visible light and absorb infrared radiation
Reviewing the answers, material D meets the requested characteristics
Number of Washers . . . Total Mass . . . Total Force . . . Ratio
1 ................................................0.6 kg ................5.9 N ........... 9.83 N/kg
2 ................................................1.2 kg ...............11.8 N ............ 9.83 N/kg
3 ................................................1.8 kg ..............17.6 N ............. 9.78 N/kg
4 ...............................................2.5 kg .............24.5 N ............. 9.80 N/kg
5 ...............................................3.2 kg ..............31.4 N ............. 9.81 N/kg
The ratios are listed in the table.
The ratio seems to be constant, and not depend on the number of washers or the total mass. It's always about 9.8 Newtons per kilogram of mass. There must be something special about that number.
