Answer:
A houseplant is usually small, and darkly colored, whereas an outdoor plant will usually have a brighter color and will more likely to grow in size. Most plants prefer a temperature of around 76-93 degrees Fahrenheit. Meaning if you like your house to be cool, your plants' growth could be stunted.
Answer to #1:
<span>Kilograms
Explanation:
The base metric unit of mass is grams.
Pounds also measure weight, but they are part of the imperial system.
Answer to #2:
Mass
Explanation:
Mass is how much space an object takes up, it is the amount of matter in an object.
Volume, on the other hand, is how much space an object takes up.

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)
