Answer:
Explanation:
Potential difference is created when a long object of length l moves perpendicular to magnetic field . The potential difference created is
V = Blv where B is magnetic field , l is length and v is velocity of length l .
here V = 45 x 10⁻⁶ x 44000 x 1.2
= 2.376 volt .
b )
Electric field = V / l ; V is potential difference between length l .
= 2.376 / 44000
= 54 x 10⁻⁶ V/m
It’s the second one because tahst like close to 4.8 so
Answer:
Explanation:
An example of an intense aerobic activity would be running/ sprinting sprinting targets six specific muscle groups: hamstrings, quadriceps, glutes, hips, abdominals and calves. Sprinting is a total body workout featuring short, high-intensity repetitions and long, easy recoveries.
On Earth, the acceleration due to gravity is (-9.8 meters per second) per second.
If the school, the roof, and the pencil are on Earth,
then after 3 seconds, the pencil's speed is
[ (-9.8 meters per second)/second ] times [ 3seconds ] = <u>-29.4 meters per second </u>
Answer:
44.71 mi/h
11.17 mi
Explanation:
To express the velocity in the S.I. you use the following equality:
then, by replacing you obtain:
When the car has traveled while 15 minutes you have:
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
TRANSLATION:
Para expresar la velocidad en el S.I., utiliza la siguiente igualdad:
entonces, al reemplazar, obtienes:
Cuando el automóvil ha viajado durante 15 minutos, tiene:
