All 15 patients will most likely have the same test results reguarding the ages would make the results vary
if this isnt a statement listed please Comment/Respond telling me the statements and I will answer to the best of my ability
Hope this helped!!
Answer:
Stratosphere and Thermosphere
Explanation: Both of these layers above earth heat as you go higher.
The average velocity of an object is given by:
Average velocity = total displacement / total time
First, we calculate the time taken to reach the maximum height of the ball. This occurs when the final velocity is 0.
Vf = Vi + at
0 = 19.6 - 9.81 * t
t = 2 seconds
The total trip will be of 4 seconds (2 seconds up, 2 seconds down)
The total displacement is given by:
s = ut + 1/2 * at²
s = 19.6 * 2 - 0.5 * 9.81 * 2²
s = 19.6 meters
This is the distance maximum height, so the total height is
19.6 * 2 = 39.2 meters
Average velocity = 39.2 / 4
Average velocity = 9.8 m/s
Answer: The correct answer is option (A).
Explanation:
Momentum of the car with 0.04 kg mass , which travelling with velocity of 2.00 m/s
Then the maximum speed of the another car in order to not to break the eggs will be same as first car:
Speed slightly more than 1 m/s will increase the momentum of second car and the eggs will break. So, from the given options the minimum speed need by the second car will be 1.42m/s.
Answer: <em>One main reason, all three experts agree, is the phenomenon known as “windthrow” which uproots a tree. “The tree trunk acts as a lever and so the force applied to the roots and trunk increases with height,” says Foster. “Taller trees are more susceptible to windthrow.”</em>
