Answer:
The time that the drop is falling =35.875 s
Explanation:
Using one of newton's equation of motion
g = V-u/t ................ Equation 1
Where V = final velocity, u = initial velocity, g = acceleration due to gravity of the moon, t = time.
<em>Note:</em> for a dropping object, u = 0 m/s
g = V/t.................... Equation 2
making t the subject of equation 2 above
t = V/g................. Equation 3
<em>Given: V= 57.4 m/s, g = 1.6 m/s²</em>
Substituting these values into equation 3
t = 57.4/1.6
t = 35.875 s
t = 35.875 s
The time that the drop is falling = 35.875 s
It would be "resonance" that is occurring that causes the nonvibrating tuning fork
<span>to begin to vibrate. Specifically the resonance of the sound waves that are traveling through air. </span>
Answer:
Explanation:
The artificial gravity generated by the rotating space station is the same centripetal acceleration due to the rotational motion of the station, which is given by:
Here, r is the radius and v is the tangential speed, which is given by:
Here is the angular velocity, we replace (2) in (1):
Recall that .
Solving for :
Answer:
about half the people who develop the condition survive.
Explanation:
Cardiogenic shock is a condition in which your heart suddenly can't pump enough blood to meet your body's needs. ... Cardiogenic shock is rare, but it's often fatal if not treated immediately.
