Answer:
clouds can consist of dry air mixed with liquid water drops, ice particles, or both. low, shallow clouds are mostly made of water droplets of various sizes. thin, upper level cloud are made of tiny ice particles.
Explanation:
The hint is "constant speed".
If there is a net force on an object, what occurs to that object? F net = m*a.... It accelerates!
So, if the desk is going at a CONSTANT speed, what does that tell you about the acceleration? There is a change in speed.
Fnet = m*a Since a = 0 Fnet = 0
Fnet = sum of the force... reflect the direction of F as the positive direction. Sum of the forces in the direction of F = 0 0 = F - friction F = friction
So, if F = 800 N, then friction = 800 N in the opposite direction.
Answer:
Elements are arranged in the table by increasing atomic number.
Explanation:
In the modern periodic table, each element is represented by its chemical symbol. The number above each symbol is its atomic number.
Answer:
0.619 cm
Explanation:
V = 2.17 m/s, diameter internal, D = 1.60 cm
v = 14.5 m/s, inside diameter, d = ?
According to the equation of continuity,
A V = a v
3.14 x (1.60/2)^2 x 2.17 = 3.14 x (d/2 )^2 x 14.5
5.5552 / 4 = d^2 x 3.625
d = 0.619 cm
