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

pls brainlist too
Answer:
I think It Should be Star B
Explanation:
As we know that in cellular phone all the signals are transmitted by antenna in the form of electromagnetic waves
All these electromagnetic waves are transmitted through the phones and then received as a signal to the receiver of another phone
These signals are then processed and converted into sound which is produced by the phone
So here correct answer will be
<em>C. The cellular telephone transmits information by electromagnetic waves to a receiver which then encodes them and produces sound.</em>
Answer:
The answer is E) 6.7m at an angle 63° north of east
Explanation:
We begin by writing out our given vectors A,B and C in their respective rectangular Cartesian coordinate form. which are given as A=8i, B=6j and C= -5j (negative because it points towards west which is towards the left which is taken as the negative direction).Now we simply add all three to obtain our final vector given by,

In the last step we just added the like components. Now we will have to calculate the magnitude and angle of V(with respect of the east direction), which is given by,

the angle alpha is always calculated with respect to the horizontal positive axis, and since both components of the vector are positive the vector lies in the first quadrant. Hence the 63° angle north of east is justified. The term north of east means the angle formed in moving from east towards the north that is from the positive horizontal axis to the positive vertical axis.
Answer:
Explanation:
Given
Initial Velocity (u)=13 m/s
angle
distance between fence and deer=2.5 m
We consider deer jump similar to projectile motion
equation of trajectory



Thus deer will cross the fence with an difference in its jump and fence
1.5-1.148=0.351 m



so deer rises during when it is over fence
