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.
<h2>
The gravitational acceleration on planet X is 32.7 m/s²</h2>
Explanation:
The acceleration due to gravity is given by
where G is gravitational constant, M is mass and R is radius.
For earth we have
g = 9.81 m/s²
That is
For planet X we have
Substituting
The gravitational acceleration on planet X is 32.7 m/s²
Knowing the distance may only give you the relative locations between two points, but not the exact location. So, the answer to his question is no. Knowing the distance does not give enough information. If perhaps the coordinates of both points were given, then that would be considered enough information.
Answer:
OK HERE
Explanation:
When raising a power to a power in an exponential expression, you find the new power by multiplying the two powers together. For example, in the following expression, x to the power of 3 is being raised to the power of 6, and so you would multiply 3 and 6 to find the new power.
Answer:
Explanation:
According to Newton's Second Law of Motion, force is the product of mass and acceleration.
The net force is 5 Newtons and the mass is 13 kilograms. Let's convert the units for force to make the problem and unit cancellation easier.
- 1 Newton (N) is equal to 1 kilogram meter per square second (1 kg*m/s²)
- The net force of 5 N is equal to 5 kg*m/s²
Now we know the values for 2 variables:
Substitute the values into the formula.
Since we are solving for the accleration we must isolate the variable, a. It is being multiplied by 13 kilograms and the inverse of multiplication is division. Divide both sides by 13 kg
The units of kilograms (kg) cancel.
The original measurements of force and mass ( 5 and 13) have 1 and 2 significant figures. We must round our answer to the least number of sig figs: 1.
For the number we found, that is the tenths place. The 8 in the hundredth place (0.384615385) tells us to round the 3 up to a 4.
The acceleration is approximately <u>0.4 meters per square second.</u>
