a coil with 50 turns and area 10cm2 is oriented with a plane perpendicular with a 0.75-T magnetic field. if the coil is rotated over(rotated through 180) in 0.20s. what is the average emf induced in it. 0.375v
Conduct a t-test for the null hypothesis against
alternative hypothesis based on 16 random
observations. The sample mean is 110 and the sample standard
deviation is 10. Use α = 0.05.
Using the standard reduction potentials, calculate the standard emf for each of the following
reactions: a. 2Al 3+ + 3Cd ⟶ 2Al + 3Cd 2+
b. Cr + 2Cr 3+⟶3Cr 2+
c. H2 + I2⟶ 2H + + 2I
An ideal double-reheat steam turbine receives 300,000 kg/h of steam at 10 MPa and 400°C. After expansion from high pressure turbine shell, it is reheated twice from saturated vapor condition back to its initial temperature. The steam entering the condenser is 97% dry. Determine (a) engine work, (b) engine thermal efficiency, and (c) steam rate. (d) Considering a generator output of 100 MW with 97% generator efficiency, what are the combined heat rate, (e)brake work, (f) brake thermal efficiency, and (g)pump power
requirement.
8. The average drive to work is 9.6 miles. Assume standard deviation is 1.8. If random sample of 36 employed who derive to work are selected, find the probability that mean of sample miles driven to work is between 9 and 10 miles.
9. The data for the car rental company is given:
Company Cars Revenue
A 63 7
B 29 3.9
C 20.8 2.1
D 19.1 2.8
E 13.4 1.4
F 8.5 1.5
Compute the linear correlation coefficient for the data and find the equation of regression line.
1. In a hospital unit, there are 8 nurses and 5 physicians; 7 nurses and 3 physicians are females. In a staff person is selected, find the probability that the subject is nurse or male.
Staff females males total
Nurse 7 1 8
Physicians 3 2 5
10 3 13
Let f and g be the functions defined by f(x)= 2x+3 g(x)= 3x+2 then composition of f and g is
