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:
λ = hv
If frequency is doubled :
λ = h × 2v
λ = 2hv
Thus wavelength is doubled
Answer:
Explanation:
The x-component is found in the magnitude of the vector times the cosine of the angle.
and, to 3 sig dig,

Answer:
v = 14 m/s
Explanation:
given,
radius of dip = 40 m
The passengers in a roller coaster car feel 50% heavier than their true weight.
Apparent weight



When the car is at the bottom, the weight will be acting downwards and the centripetal force will also be acting downward where as Normal force which is apparent weight will be acting in upward direction.
now,





v = 14 m/s
Answer:
negative
Explanation:
positive charges attract negative charges and vice versa. and are possible to nullify
