Answer:
Cost per year = $131.4
Explanation:
We are given;
Power rating of computer with monitor;P = 300 W = 0.3 KW
Cost of power per KWh = 15 cents = $0.15
Time used per day by the computer with monitor = 8 hours
Thus; amount of power consumed per 8 hours each day = 0.3 × 8 = 2.4 KWh per day
Thus, for 365 days in a year, total amount amount of power = 2.4 × 365 = 876 KWh
Now, since cost of power per KWh is $0.15, then cost for 365 days would be;
876 × 0.15 = $131.4

Answer:
Final angular velocity is 35rpm
Explanation:
Angular velocity is given by the equation:
I1w1i + I2w2i = I1w1f -I2w2f
But the two disks are identical, so Ii =I2
wf can be calculated using
wf = w1i - w2i/2
Given: w1i =50rpm w2i= 30rpm
wf= (50 + 20) / 2
wf= 70/2 = 35rpm

Answer:
its x and y component is 24.749m/s
Explanation:
Given
Speed of the dog = 35m/s
x component of the speed = xcos theta
y component of the speed = ycos theta
Given theta =45 degrees
x-component = 35cos45
x-component = 35(0.7071)
x-component = 24.749m/s
y-component = 35sin45
y-component = 35(0.7071)
y-component = 24.749m/s
Hence its x and y component is 24.749m/s
