Answer:
v_kyle = 0.5 m/s
v_jennies = 0.333 m/s
Kyle's Rabbit was the fastest
Explanation:
For the velocity of Kyle's Rabbit:
d = distance covered = 40 m
t = time taken = (1 min)(60s/1 min) + 20 s = 80 s
<u>v_kyle = 0.5 m/s</u>
For the velocity of Jennies Rabbit:
d = distance covered = 30 m
t = time taken = (1 min)(60s/1 min) + 30 s = 90 s
<u>v_jennies = 0.333 m/s</u>
It is clear from the results that:
<u>Kyle's Rabbit was the fastest</u>
Answer:
D
Explanation:
Sana maka tulong huhuhuhuh
Answer: Part A the right sentence is: Because the proton is a positive charge and it slows down as it travels, it must be moving from a region of lower potential to a region of higher potential
Part B. aproximatelly 98 times ΔV V
Part C. the initial kinetic energy of the proton is 1.87 10^3 eV
Explanation: Part A. The field stops the proton so the lines of electric fild must be directed in opposite direction of its movement. This means that the proton moves to a higher potential. Part B The kinetic energy of the is transformed in electric potenctial for the proton.
Part C. Energy in J divide the charge of electron gives the energy in eV.
its because it allows modern astronomers the ability to see farther out and more accuratly
