The period of the trig function graph is 2pi
Go from crest to crest and measure the distance and that is the length of one period or 1 cycle of the wave.
Hope this helped! Any questions please feel free to ask. Have a great day!
Their monthly income is 4,650.
Multiply that by 12 to find the yearly income:
4650 x 12 = $55,800
Based on the yearly income the answer is D. Virginia or Texas
Answer:
Work done is the product of distance and force, it is measured in joules.
Power is the rate of work done given by dividing the work done by time
Power (watts)= workdone (J)/ time (s)
= 50,000J/7 sec
= 7142.857 watts
Therefore, the power of the car during the race was 7142.857 watts
Step-by-step explanation:
An inertial reference frame is a frame of reference in which a body remains at rest OR moves with a constant LINEAR velocity. Answer choices A, C, and D are moving linearly at a constant rate and are all inertial frames of reference. Answer choice E is motionless, and is therefor an inertial frame of reference. Answer choice B is rotating at a constant rate. Rotation is not an inertial frame of reference.
Therefor, the answer is B.
Given:
An unpainted roof. Assuming the dimensions of the roof are 10 meters by 5 meters by 0.2 meters. To solve for the total surface area of the roof to be painted:
SA = 2 (wl + lh + wh)
SA = 2 ( 10*5 + 10*0.2 + 5*0.2)
SA = 106 square meters
