F = m A (Newton #2)
m = F/A
m = (12.2 N) / (265.2 m/s²)
m = (12.2 / 265.2) kg
<em>m = 0.046 kg </em>
(46 grams; not bad; the international standard is "not more than 45.93 grams")
Note: 265.2 m/s² = about 27 G's . Seems to me like that would rip the ball to shreds, but I don't really know anything about golf.)
The frequency of the second harmonic is 880 Hz (a pitch of A5). The speed of sound through the pipe is 350 m/sec. Find the frequency of the first harmonic and the length of the pipe. The length of an air column is related mathematically to the wavelength of the wave which resonates within it.
Answer:
44m/s is the speed of that particle after 8 seconds
Answer:
Thin, aluminium and buried underground.
Explanation:
When it comes to electrification of a state or province, some characteristics of the wire to use must be considered. This would help to minimize and avoid power loss and wire burns.
i. The wire to use should be thin, and a quite number can be twisted one against the other so as to increase the surface area for heat dissipation.
ii. Aluminium wire is more preferable for this project. It has a high melting point, and reduces energy loss.
iii. Burying the wire underground through an insulator is the best choice, though expensive but would preserve the wire from external influence.
Answer:
The time taken for the paint ball to hit the ground is 
The distance of the landing point from the tower is 
Explanation:
From the question we are told that
The height of the tower is 
The speed of the paintball in the horizontal direction is 
Generally from kinematic equation we have that
Here u is the initial velocity of the paintball in the vertical direction and the value is 0 m/s , this because the ball was fired horizontally
a is equivalent to 
t is the time taken for the paintball to hit the ground
So
=>
Generally the distance of its landing position from the tower is
=> 
=>
