A build up of charges on a sock from a dryer
It is generally the brightest compared to the other stars in the constellation.
Answer:
Explanation:
To detrmine the time interval at which the balls are in contact.
<u>Given information</u>
The mass of each steal ball 67.8g. The speed of ball towards each other is 4.80 m/s. The exerted force by each jaw 15.9 kN and the forece reduce the diameter by 0.130 mm.
Expression for the effective spring constant ball is shown below.
K = |F|/|x|
Here,
k is a spring constant
F is the force exerted on the ball
x is dispalcement due force
substitute 15.9 kN for F and 0.130 mm in above equation
<h2>K = (15.9 kN)(1X10³N)
/ (0.130 mm)(1x10⁻³m/1mm)</h2><h2>
122 x 10⁶ N/m</h2>
The spring constant is 122 x 10⁶ N/m
