Point of reference - an indicator that orients you generally; "it is used as a reference for comparing the heating and the electrical energy involved"
Answer:
4.198 seconds
Explanation:
The total length of the yacht is 30m and the width of the bridge is 14.5m.
The speed of the yacht is 10.6m/s.
We can assume the current of the canal has a speed of 0m/s.
To calculate the answer we will break it into two parts
1) The time it takes for the bow to travel from the start of the bridge to the end
<em>Formula Speed = Distance / Time</em>
Speed = 10.6m/s
Distance = 30m
Time = T1
T1 = 2.8301s
2) The time it takes for the stern to cross the end of the bridge after the bow
<em />
<em>Formula Speed = Distance / Time</em>
<em />
Speed = 10.6m/s
Distance = 14.5m
Time = T2
T2 = 1.3679s
3) The Total Time is
Total = T1 + T2
Total = 4.198s
Answer:
The average velocity from 1 to 3 seconds is 20 m/s l. X/T = 0 m/1s = zero.

c because a generator generates electricity with the use of another energy source like nuclear,solar,wind,fossil fuel,gasoline or in rare cases temperature
1)The total of the electric flux out of a closed surface is equal to the charge enclosed divided by the permittivity. The electric flux through an area is defined as the electric field multiplied by the area of the surface projected in a plane perpendicular to the field.
