<span>(a) 0.0676 l
(b) 67.6 cc
We are given that 5.00 L of blood circulates through the heart every minute, with the heart beating 74.0 times per minute. Therefore, for each heartbeat, 5.00 L / 74.0 = 0.067567568 L of blood passes through. Rounding to three significant figures, the result is 0.0676 l. To convert liters to cubic centimeters, multiplying by 1000 leads to 67.6 cc of blood per heartbeat.</span>
Answer:
It eliminates recoil.
Explanation:
Every action has a corresponding reaction that is equal and opposite.
According to the conservation of momentum, when a single spore is released, the fern experiences a recoil that diminishes the energy and velocity of the spore. However, by ejecting the spores in pairs, the recoil is neutralized, allowing the entire energy to be imparted to the spores, which leads to increased launch speeds.
The response is outlined below. Audio power amplifiers are present in various sound systems, including those for sound reinforcement, public addresses, home audio, and musical instrument amplifiers like those for guitars. This component is the final electronic element in the audio playback chain before signals reach the loudspeaker. To achieve the loudest possible sound, it is essential to maximize output while maintaining high input and low output impedance.
Part a) The package's speed matches the helicopter's speed in the horizontal direction. Thus, after a time "t", the horizontal velocity remains constant, while in the Y-direction, it begins to fall under gravity. Part b) The distance relative to the helicopter is equivalent to the distance it falls freely. Part c) If the helicopter is ascending uniformly, the package's final speed after time t can be described in terms of its initial speed and gravity.
