A. 0.5 hz because frequency os the amount of waves that pass per one second.
This is problem of free falling
objects, which can be solved using the formula:
V = sqrt(2gy)
Where v is the velocity upon
impact
G is the acceleration due to
gravity ( 9.81 m/s2)
Y is the height
Since Venessa is 3.5 m
Y = 30 -3.5 = 26.5 m
V = sqrt(2 (9.81 m/s2) ( 26.5
m))
<span>V = 22.8 m/s</span>
Answer:
Shape the pot so that it has a narrower base and the same size rim.
Explanation:
Answer:
0.5 hours or 30 minutes
Explanation:
each hour travels 80km
so, time taken= 40/80 hours
= 0.5 hours
= 30 minutes
Needs work. 100kmph is not a velocity. Deceleration is not sudden. There is no such thing as the "speed" of deceleration. 10 kmph is not a deceleration. And if it were, we would need to know HOW LONG it decelerated. Otherwise an engaging and intriguing question.
