Answer:
Spring constant, K = 415.9 N/m
Explanation:
The period of vibration of a spring, T, is given by:
T = 2√m/K
Where m = mass of the body in kg, K = spring constant or force constant or elastic constant or stiffness in Nm-1
Making K the subject of the expression,
K = m(2)2/(T)2
K = 4m()2/(T)2
Where m = 0.38kg, = 3.14285714286, T = 0.19s
K = 4 x 0.38 (3.14285714286)2 / (0.19)2
K = 4 x 0.38 x 9.87755102043 / 0.0361
K = 15.0138775511 / 0.0361
K = 415.9 Nm-1
Answer:
Option C
Equal environment
Explanation:
The equal environment assumption is a biometric model that predicts how far the monozygotic twins are correlated to each other upon their exposure to environmental effects which are of etiologically significance to the trait/traits under consideration.

Answer:
- overtime premiums being charged to the direct labor account
- skilled workers being assigned to jobs requiring little skill.
Explanation:
Unfavorable labor rate variances occur when labor expenses supersede management expectations, thus causing cash flow problems, stagnation of profit, etc. It indicates that the cost of labor is way expensive than anticipated. A number of variations may cause such unfavorable variance. Some of them include staffing variance, pay premium, scheduling problem, etc. Identification of the cause can help to prevent their impact and or limit their impact.
