No. A substance floats or sinks in another substance because of
the densities of both of them.
If the density of the substance is more than the density of the other
one, it will sink. If less than the density of the other one, it will float.
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
Assuming the object was originally at rest, it must have been traveling for
14.0/3.45 = 4.06 seconds
Answer:
The depth of the water at this point is 0.938 m.
Explanation:
Given that,
At one point
Wide= 16.0 m
Deep = 3.8 m
Water flow = 2.8 cm/s
At a second point downstream
Width of canal = 16.5 m
Water flow = 11.0 cm/s
We need to calculate the depth
Using Bernoulli theorem
Put the value into the formula
Hence, The depth of the water at this point is 0.938 m.
The basic monomer of a lipid is a triglyceride. It breaks down into one glycerol molecule and 3 fatty acid tails.
