The answer is stomata. The process through which this occurs is known as transpiration.
Hope I helped :
Answer:
15.0 m/s
Explanation:
When elastic collision occurs, the final velocities, v of the bodies are obtained by
Where u and m denote initial velocities and mass while the subscripts 1 and 2 are for tennis ball and the other ball
Substituting 0.311 for mass of tennis, 0.0570 for mass of the other ball, 30.3 m/s for velocity of tennis ball and -19.2 m/s
Work is done when a motion resulted from the force being done by an object. The amount of work done is calculated by multiplying the force applied and the distance traveled. It is calculated as follows:
Work = Force x distance = 280 N x 5 m = 1400 J.
Answer:
a. 5 Hertz
b. 35 rotations
Explanation:
a. Frequency is given by where is the period, in seconds. Given that , the frequency of this object's rotation is:
b. Since one rotation, or period, is completed in 0.2 seconds, divide the amount of time (7 seconds) by the time it takes to complete one revolution (0.2 seconds):
The noble gases are the least reactive elements.
