D I think, but double check elsewhere.
Having a given problem of 79.5 miles per hour to be converted to meters per second, we need to know the constant values of 1 mile = 1609 meter, 1 hour = 60 minutes and 1 minute = 60 seconda. To solve, (79.5 mi/1 h)x(1609 m/ 1 mi)x(1 hr/60min)x(1 min/60 sec). The final answer would be 35.53 m/s.
Advantage of series circuit :
1. allows all the components in the circuit to have same current flowing through them.
2. one switch is enough to turn off all the components in the circuit in series.
3. make the circuit small by using smaller length of wire.
Disadvantages of series circuit :
1. If one component becomes defective , it does not allow other components to operate, since they share same current.
2. all components can not have same voltage across them.
Explanation:
What characteristics must the movement of a person have so that the value of the displacement is equal to the distance traveled?
Displacement is equal to the shortest path covered by an object. It is given by the difference of final position and the initial position.
Distance is equal to the total path covered by an object during the journey.
When an object moves in a straight line path, in this case, the displacement is equal to the distance traveled.
( 8.10) x 10^4 J = ½(1010kg)V²
<span>......................= 505V² </span>
<span>( 8.10) x 10^4 J =[(.0505) x 10^4] V² ........<==10^4 cancels </span>
<span>8.10 = .0505 V² </span>
<span>.........______ </span>
<span>V = ²√ 160.4 </span>
<span>V= 12.6 m/s </span>
<span>(that's 12.6m/sec(1km/1000m)(3600secs/1hr) = 45.36kph) </span>
<span> my diagram is wrong, it is just an ordinary car, </span>
