Answer:
What part of the light wave is related to the brightness of the light?
Amplitude
The amplitude of a wave tells us about the intensity or brightness of the light relative to other light waves of the same wavelength
The brightness of light is related to intensity or the amount of light an object emits or reflects. Brightness depends on light wave amplitude, the height of light waves. Brightness is also somewhat influenced by wavelength.
Answer:
35.7 kg
Explanation:
We are given that
Left scale reads =200N
Right scale reads=150 N
We have to find the mass in kg.
We know that
Weight of child= Sum of two scales=200+150=350 N
Acceleration due to gravity=
We know that
Weight= mg
Using the formula
Hence, the mass of child=35.7 kg
Answer and Explanation
The concept of parallax and relative motion is responsible for this.
That is, the photographer's motion prompts her to see parallax for the man and the trees, because their positions appear to keep shifting even though they are not really moving.
The heat released or absorbed by a process where temperature changes is calculated from the product of the mass of the sample, its heat capacity (4.18 J/g C for water) and the change of the temperature.
Heat = mC(T)
Heat = 90 (4.8) (64) = 27648 J or 27.65 kJ needed
