Answer:
The gravitational acceleration of the planet is, g = 8 m/s²
Explanation:
Given data,
The distance the object falls, s = 144 m
The time taken by the object is, t = 6 s
Using the III equations of motion
S = ut + ½ gt²
∴ g = 2S/t²
Substituting the given values,
g = 2 x 144 /6²
= 8 m/s²
Hence, the gravitational acceleration of the planet is, g = 8 m/s²
Answer:
you would expect a change in the graph
Explanation:
Answer:
Required diameter of hose pipe = 0.2864 mm
Solution:
From the continuity eqn, the fluid flow rate is given by:
Av = 
where
A = cross-sectional area = 
r = hose pipe radius
v = velocity of gas
Also, 
Using:
1 gallon = 3.854 l
1 mile = 1609.34 m

Therefore,






The diameter of the hose pipe = 2r = 
The diameter of the hose pipe = 
Answer:
Meandering
Explanation:
A meander is known as the continuous flow of regular curves which are sinuous, loops, turns, bends or winding in the channel of river
Production of a meander by a river or stream as it erodes the sediments comprising on an exterior, a concave bank and deposits it and other sediment on the downstream on an interior, convex bank which is like a point bar.
Rivers or streams with a one channel and sinuosities of 1.6 or more are defined as meandering rivers or streams.
