<h2>Answer:</h2>
False:
<h2>Explanation:</h2>
Jet streams are like rivers of wind high above in the atmosphere which have a huge influence on climate because they can push air masses and affect weather patterns. Jet streams travel in the tropopause which is the boundary between the turbulent troposphere and the calm, cold stratosphere. So we can say that jet streams lie in stratosphere and not in mesosphere.
Answer:
Answer is option b) 2.97m
Explanation:
With the relationship between the force exerted by the runner and the mass that it has, I can determine the acceleration it will have:
F= m × a ⇒ a= (650 kg ×(m/s^2)) / (70kg)= 9.286 (m/s^2)
With the acceleration that prints the force exerted and the time I can determine the distance traveled in the interval:
Distance= (1/2) × a × t^2 = (1/2) × 9.286 (m/s^2) × ((0.8s)^2)= 2.97m
Decrease in atmospheric ozone, which results in lower protection from various stellar particles
Answer:
T = 0.83 seconds
Explanation:
Given that,
The mass attached to the spring, m = 1.5 kg
The amplitude of the spring, A = 0.3 m
The spring constant of the spring, k = 85 N/m
We need to find the period of the mass's motion. The time period in spring mass system is given by :
So, the period of the mass's motion is 0.83 seconds.
