We don't even need to know how many pulses were produced
in those 3 seconds.
The beginning of the first pulse took 3 seconds to travel
45 centimeters from the generator.
Its speed is (45 cm) / (3 sec) = 15 cm/sec.
Average <u>speed</u> = (distance covered) / (time to cover the distance) =
(5m) / (15 sec) =
(5/15) (m/s) = <em>1/3 m/s</em> .
Average <u>velocity</u> =
(displacement) / (time spent traveling) in the direction of the displacement
Average velocity = (5m) / (15 sec) left =
(5/15) / (m/sec) left =
<em>1/3 m/s left</em>.
A number without a direction is a speed, not a velocity.
Answer:
What separates athletes from their competitors is the word itself, separation — gaining it on the offensive side, or taking it away on the defensive side (There are exceptions of course, one being the contest of offensive linemen and defensive linemen in football where the inverse is true). Speed, strength, and power are great ways to create separation in sports. However, speed, strength, and power all have genetic ceilings
Answer:
Explanation:
Given that,
Electric Field is
E = 650 N/C
The potential at x1 = 3 is
V1 = 1700V
What is the potential at x2 = 1
V2 =?
Electric potential is given as
V = Ed
Then,
E = V/d
Therefore, the electric field is gradient of the potential and the position.
So,
E = —∆V / ∆x
E = — (V2 — V1) / (x2 — x1)
E = —(V2—1700) / (1—3)
650 = — ( V2—1700) / -2
650 × -2 = —V2 + 1700
-1300 = -V2 + 1700
V2 = 1700+1300
V2 = 3000 V
