Answer:
A
Explanation:
You have to repeat it to see which result you see more of, because that would most likely be the correct solution.
Option A I guesss. Not sure
Answer:
A. 21 rad/s
B. 200.5 rpm
C. 26.46 rad/s2
D. 0.299 Hz
Explanation:
Parameters given are:
Tangential velocity,v = 1.26m/s
Diameter (outer edge) = 0.120m
Outer edge radius, ro = 0.12/2
= 0.06m
A. Calculate Angular velocity
Angular velocity, w = v/r
= v/ro
= 1.26/0.06 = 21 rad/s
In rpm,
2pi/60 rad/s = 1 rpm
1 rad/s = 60/2pi rpm
Sp, 21 rad/s = 60 * 21/2pi rpm
= 200.5 rpm
B. Calculate the inner edge radius, ri given w = 500 rpm
Converting rpm to rad/s,
= 2pi/60 * 500 rad/s
= 52.34 rad/s
ri = v/w
= 1.26/ 52.36
= 0.024m
C. Calculating centripetal acceleration, a from the outer edge, ro
a = v2/r = w2r
= (1.26)2/0.06
= 26.46 rad/s
D. Calculate the frequency, f of the outer edge angular velocity, w = 21 rad/s
f = 2pi/w
= 2pi/21
= 0.299 Hz (or per second)
Answer:
The drops of water in the clouds are heavy enough to fall.
Explanation:
Precipitation forms in the clouds when water vapor condenses into droplets of water. When the droplets are heavy, they fall to the Earth. These droplets can fall in the form of rain, hail, or snow.
<span>Biomes are typically not classified by temperature, because some biomes can experience extreme temperatures from one season to the next. Other biomes might have a more consistent temperature throughout the year. Hope this answers the question. Have a nice day.</span>
