Answer:
Gamma rays is the correct answer.
Explanation:
Answer:
a They both exhibit the Doppler effect.
Explanation:
When source of light or sound and the observer will move relative to each other then due to relative motion of them the frequency of light or sound that is observed by the observer is different from its actual frequency. This phenomenon is known as Doppler's effect.
So here the same characteristic that is exhibit by both is Doppler effect
apart from this
Light is transverse in nature while sound wave is longitudinal
Sound moves faster in water while light moves fastest in air
light do not requires any medium while sound requires medium to travel
so correct answer will be
a They both exhibit the Doppler effect.
Answer:
Mass of Little Sister = 44.17 kg
Explanation:
From Newton's second law of motion, the magnitude of force applied on the sled is given by the following formula:
F = ma
where,
F = Force Applied = 120 N
a = Acceleration = 2.3 m/s²
m = Mass of Sled + Mass of Little Sister = 8 kg + Mass of Little Sister
Therefore,
120 N = (2.3 m/s²)(8 kg + Mass of Little Sister)
(120 N)/(2.3 m/s²) = 8 kg + Mass of Little Sister
Mass of Little Sister = 52.17 kg - 8 kg
<u>Mass of Little Sister = 44.17 kg</u>
For the first question, make a question that is quantifiable
or can be counted. This can be anything, as long as its quantifiable, like "How many species of trees are in this certain area?" While for the second it can be a question that can is more
qualitative and are more open-ended questions, example, “What are the
contaminants present in this water sample”
