here's what you require:
The mass of the material,
m
The temperature change that occurs,
Δ
T
The specific heat capacity of the material,
c
This is the amount of heat required to raise 1 gram of that substance by 1°C.
The heat will increase
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
I believe this would be frequency, as wavelength measures the waves themselves, and a period is a section of time. Wave speed is the speed of their movement.
I'm pretty sure its d. because depends what tipe of dog it is there are some that see different colors so I'm pretty sure its d.
