Answer:
Tension, T = 0.1429 N
Explanation:
Given that,
Mass of the rock, m = 0.0450 kg
Radius of the circle, r = 0.580 m
Angular speed,
The tension in the string is balanced by the centripetal force acting on it. It is given by :
Since,
T = 0.1429 N
So, the tension in the string is 0.1429 N. Hence, this is the required solution.
Answer:
The distance travel in its lifetime of earth is
Explanation:
Change respecto the pion
The speed of the pion:
Knowing the speed of the light is about
Now to determinate the distance
The color can be determined by either the frequency or the amplitude. The amplitude is the maximum height of the wave, while frequency is the number of cycle (amplitude to amplitude) per second. <em>Thus, the answer would be: the amplitude of the wave.</em>
Answer:
b
Explanation:
b. increased frequency and severity of forest fires
Because of the Global warming the forest fires have increased drastically. The recent fire in Amazon rain forest is an example of this. These burning forests emit a large amount of CO2 yet again and further causing more global warming. According a a recent data it is estimated that forest fire emit about 8 million tons of CO2 in the atmosphere in last 20 years. In,2017 total global CO2 emission has reached to 32.5 billion tons, according to IEA.
