Answer:
D is the answer wave behavior
Assuming that the distance from the heart to the brain is 30 centimeters, and the motion of blood in the aorta is 30 centimeters per second. There fore to solve for the time needed for the blood to reach the brain is:
t = 30 centimeters / 30 cm per second
t = 1 second.
The regular heart rate is 70 beats per minute, solve for the equivalent number of beats:
number of beats = 70 beats / minute * (1 min / 60 seconds) * 1 second
number of beats = 1.2 beats
Therefore, it takes 1.2 beats for the heart to pump blood to the brain.
Answer:
-21.6 m/s^2
Explanation:
First of all, we need to convert the initial and final velocities into m/s:
is the initial velocity
is the final velocity
The acceleration is given by

where
t = 90 s is the time elapsed
Substituting the numbers, we find

and the negative sign means the rocket is decelerating.
Answer:
force, mass, and acceleration
Explanation:
According to Newton's 2nd law, the acceleration of an object depends on the net force and the mass of the object. The equation for the 2nd law is Force = mass * acceleration.
