Answer:The fastest recorded human footspeed was recorded between 60 and 80m in Bolt's world record 9.58-second 100m final in Berlin in 2009. Bolt was clocked at 44.72km/h, which is 27.8mph. The Jamaican covered the distance between 60-80m in a time of just 1.61 seconds
Explanation:
pls brainlist too
Answer:
E =17,280 J
Explanation:
Since the voltage drops linearly from 6V to 4V, the average is 5V. The energy delivered is .
V is the average of initial and fianl voltage
A is the current passing
t is the time in which current is passed
E=V*A*t = 5*0.015*(64*3600) = 17,280 J
Answer:
non linear square relationship
Explanation:
formula for centripetal force is given as
a = mv^2/r
here a ic centripetal acceleration , m is mass of body moving in circle of radius r and v is velocity of body . If m ,and r are constant we have
a = constant × v^2
a α v^2
hence non linear square relationship
Formula: Ca=Vt^2/r
centripetal acceleration(Ca)= ?
tangential speed(Vt)= 2.8m/s
Radius(r)=2m
Substitute: Ca=2.8^2/2
Ca=3.92m/s^2
140 ? i’m guessing there doesn’t look like there’s much to the question
