The distance from Buzău to Iaşi is 72 km. Find out the time a vehicle travels this distance if it has a speed of 72 km per hour. Expresses the speed in the unit of measurement in SI. I give the crown! Thank you
Answer:
3600seconds
Explanation:
Given parameters:
Distance = 72km
Speed = 72km/hr
Unknown:
Time it takes for the vehicle to travel the distance = ?
Solution:
Speed is the distance divided by time;
Speed = 
time =
Insert the parameters;
time = 
= 1hr
The SI unit of time is in seconds;
3600 seconds is 1hr
The time is 3600seconds
R 3/4 = (R3 * R4) / (R3 + R 4) = ( 9 * 18 ) /(9 + 18 ) = 162 / 27 = 6 Ohms
R e = R 1 + R 2 + R 3/4 + R 5 = 3 + 6 + 6 + 15 = 30 Ohms
I = U / Re = 90 V / 30 Ohms = 3 A
Finally for the voltage U 3/4 ( the parallel portion of the circuit ):
U 3/4 = 6 Ohms * 3 A = 18 V
Answer: 18 V
If the award weighs 200 newtons and 200 newtons equals 44.96 pounds of force even though it is of such a force if it hits the ground the energy will either discharge into the air doing nothing but creating a loud sound or it will discharge into the ground altering the ground that it landed on.
Hope this helps :)
okay , but what is this i dont understand .
Answer:
D
Explanation:
The reason why it's D is because it show a real life example were you can use velocity
