Answer: A. If the surface aquifer has a high water table
Explanation:
The water table refers to the water level underground. If it is high, it means that the water underground is close to the surface such that if a well was dug, it would not need to be dug too far for water to be seen.
When heavy rain falls, flooding is avoided if the water is either able to run off efficiently or if the ground is able to absorb the water. When the water table is high, it means that the ground will not be able to absorb much because the water is already close to the surface which means that should heavy rain fall, there will most likely be a flood.
F = m * a
a = F / m = 2.050.000 N / 40.000 kg ( 1 N = 1 kgm/s² )
a = 51.25 m/s²
Answer:
Explanation:
Given data
Mass of elevator m=3.0×10³kg
Time t=23 seconds
Height d=210 m
Concept:
Power is defined as rate at which work is done by force is said to be the power due to force.
The power can be calculated as
First we need to find the force by applying newtons law of motion
So
Now we need to find the velocity V
So
Now to put values of Force and velocity to find the power.As the force have same direction of motion so angle is zero
Answer:
The displacement of the spring, as measured from equilibrium, is 0.301 m
Explanation:
Hi there!
Using Hooke´s law, we can calculate the displacement of the spring:
F = -kx
Where:
F = restoring force exerted by the spring.
k = spring constant.
x = displacement of the spring.
The force exerted by the spring can also be calculated using the Newton law:
F = m · a
Where:
F = force.
m = mass of the object.
a = acceleration.
Then, combining both laws:
F = -k · x = m · a
-k · x = m · a
-339 N/m · x = 10.0 kg · 10.2 m/s²
x = 10.0 kg · 10.2 m/s² / -339 N/m
x = -0.301 m
The displacement of the spring, as measured from equilibrium, is 0.301 m
Based on the nature of constructive interference,
none of the wave intersections will produce constructive interference.
<h3>What is constructive interference?</h3>
Constructive interference is interference that occurs when two waves of the same frequency amplitude and wavelength travelling in the same direction are superposed with the resultant effect of reinforcement of both waves to produce a larger wave.
Constructive interference occurs when the path difference between two identical waves at a point is:
where n = 0, 1, 2, ...
For the various intersections:
- 1.77 cm crest intersecting with a 0.65 cm crest; n = 1.77/0.65 = 2.7
- A 1.2 mm crest intersecting with a 3.9 mm trough is destructive.
- A 4.55 N trough intersecting with a 1.59 N trough; n = 4.55/1.59 = 2.8
- A 0.44 inch trough intersecting with a 0.72 inch crest is destructive.
- A 7.42 mm trough intersecting with a 1.93 mm trough; n = 7.42/1.93 = 3.8
Therefore, none of the wave intersections will produce constructive interference
