Answer:
Explanation:
The distance of searchlight will act as radius R and velocity of car may be supposed to be tangential velocity v . We are required to calculate angular velocity ω .
v = 80 ft /s
R = 3000 ft
ω = v / R
= 80 / 3000 = .027 rad / s
For angular acceleration the formula is
angular acceleration α = a / R
a is linear acceleration = 15 ft / s²
α = 15 / 3000 = .005 rad / s².
To determine the velocity of the roller coaster as it moves down, we use the kinematic equation which is expressed as 2gy = vf^2 - v0^2 where g is the gravitational acceleration, y is the elevation of the roller coaster, vf and vo are the final and initial velocity. We calculate as follows:
2gy = vf^2 - v0^2
Since it starts at rest, v0 is zero.
2gy = vf^2
vf = √2gy
vf = √2(9.8)(101)
vf = 44.5 m/s
1) Gametophyte
2) Gametes
3) Zygote
4) Sporophyte
These are all related because they all help undergo mitosis, and are used in the Life Cycle of Plants.
Answer:
Place theory.
Explanation:
Place theory explains the different perception of sounds on the basis of the different sound waves. This theory helps to explain how the individual can differentiate different pitch sounds.
The different sound frequency causes vibration at the basilar membrane of the cochlea. The different areas of cochlear membrane gets activated by the different frequency of sound. These different vibration enable to distinguish between high pitch and low pitch sounds.
Thus, the answer is place theory.
