Answer:
Explanation:
Momentum is conserved in an inelastic collision. In a completely-inelastic collision, both objects have a common final velocity. Once the relative speed between the mosquito and the raindrop is zero, the mosquito is able to detach from the drop and escape
The final velocity and the loss of kinetic energy is mathematically given as
- vf = 0.087 m/s
- L-K.E= 81.5 J
<h3>What are the final velocity and the loss of kinetic energy?</h3>
Question Parameters:
Generally, the equation for the conservation of momentum is mathematically given as
m1v1 = m2v2
(7500 + 4000) * vf = 4000 * 0.250
vf = 0.087 m/s
b)
Generally, the equation for the loss of kinetic energy is mathematically given as
loss in kinetic energy = initial kinetic energy - final kinetic energy
Therefore
L-K.E= 0.50 * 4000 * 0.25^2 - 0.50 * (4000 + 7500) * 0.087^2
L-K.E= 81.5 J
In conclusion, the final velocity and the loss of kinetic energy
vf = 0.087 m/s
L-K.E= 81.5 J

<span>As of January 2, 2018, the penalty for an OSHA violation is $12,934 per violation (serious). An employer can experience charges of $12,934 per day beyond the abatement date of the violation, and the maximum amount that OSHA can impose as a penalty on an employer for each willful violation is $129,336 per violation.</span>
Answer:
The answer is 8 [gr/cubic centimeter]
Explanation:
We know that the definition of the density is defined by the mass of the object or substance divided by its volume.
Therefore:
For this problem:
![density =\frac{12}{1.5} \\density=8[grams/cm^3]](https://tex.z-dn.net/?f=density%20%3D%5Cfrac%7B12%7D%7B1.5%7D%20%5C%5Cdensity%3D8%5Bgrams%2Fcm%5E3%5D)
