Answer:
The answer is building Wind Barriers
The reasoning is because irrigation, if used too much, causes water erosion. Planting crops deeper in the ground would would prevent the plants from being uprooted. Finally, terracing would prevent from run-off eroding the ground away from the plants.

A student named Bob is on a bike and the mass is 50 kg. The force causes the student to accelerate at 3 m/s to the power of 2. Calculate the net force that causes this acceleration.???
Answer:
150 N
Explanation:
Force is equal to mass times acceleration. 50 kg accelerating at a mass of 3m/3² is undergoing a force of 150 m/s², or 150 Newtons
How energy and power are different ???
Answer:
Explanation:
Energy is what makes change happen and can be transferred form one object to another. ... Power is the rate at which energy is transferred. It is not energy but is often confused with energy. The watt is the most commonly used unit of measure for power.
A 50 kg object is accelerating to the right at 5 m/s2. What is the net force acting on the object?
Answer:
250 NExplanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 50 × 5
We have the final answer as
250 NHope this helps you

Where does the kinetic energy people get during the sport come from?
Answer: When you hit a ball with a bat or racquet, work is done. A runner does work when they accelerate and acquire kinetic energy. Once that kinetic energy is achieved, work continues to be done just to overcome friction and maintain speed. Energy comes from the food they eat.

What is the relationship between the sizes
of the planets and their distances from the sun?
Answer:
The inner, rocky planets are smaller than the outer, gaseous planets
Explanation:
The relationship between the sizes of the planets and their distances from the Sun is: The smaller planets are closer to the sun while the bigger planets are farther from the sun.
A solar system can be defined as a collection of both the inner and outer planetary bodies alongside the Moon in orbit (travel) around the Sun, in slightly elliptical orbits.
Basically, the nine (9) planets of the solar system orbiting (traveling) in order of their distance around the Sun are;
Mercury.Venus.Earth.Mars.Jupiter.Uranus.Neptune.Pluto.Venus.Saturn.Basically, the relationship between the sizes of the planets and their distances from the Sun is that the smaller planets are closer to the sun while the bigger planets are farther from the sun.

An object has an x-momentum of 8.5 kilogram-meters/second and a -momentum of 9.8 kilogram meters/second. What Is resultänt
momentum of the object?
OA 15.5 kilogram-meters/second
OB. 14.8 kilogram-meters/second
0c 12.97 kilogram-meters/second
OD. 16.8 kilogram-meters/second
Answer:
The resultant momentum is 12.97 kg.m/s. Choice: c
Explanation:
Momentum
The momentum is a vector that measures the quantity of motion that an object has. It's also known by the term "mass in motion".
As a vector, it can be expressed by its rectangular components:
[tex]\vec p = p_x\mathbf{i}+p_y\mathbf{j}[/tex]
The magnitude of the momentum is:
[tex]\mid \mid \vec p \mid \mid =\sqrt{p_x^2+p_y^2}[/tex]
The object described has an x-component of:
px=8.5 Kg.m/s
And a y-component of:
py=9.8 Kg.m/s
Thus, the magnitude of the momentum is:
[tex]\mid \mid \vec p \mid \mid =\sqrt{8.5^2+9.8^2}[/tex]
[tex]\mid \mid \vec p \mid \mid =\sqrt{72.25+96.04}[/tex]
[tex]\mid \mid \vec p \mid \mid =\sqrt{168.29}[/tex]
[tex]\mid \mid \vec p \mid \mid =12.97[/tex]
The resultant momentum is 12.97 kg.m/s. Choice: c

There are three types of friction. ______________ friction occurs when an object is not moving. ______________ friction occurs when an object is moving against another surface. ______________ friction occurs in the case of wheels or other round objects. The amount of friction depends on two things.First, how ______________ the surfaces are; and second, how ______________ the object is. It is ______________ to keep an object moving than to start it moving. This is because static friction is ______________ than sliding friction.

A student buys a plastic dart gun and tries to find the maximum horizontal range. The student shoots the gun straight up and it takes 3.7 seconds for the dart to return back to the height of the barrel. What is the maximum horizontal range of the gun?
Answer:
The value is [tex]R_{max} = 33.54 \ m[/tex]
Explanation:
From the question we are told that
The total time of flight is [tex]t = 3.7 \ s[/tex]
Generally from kinematic equation
[tex]v = u - g * \frac{t}{2}[/tex]
So v is the velocity at maximum height and the value is v = 0 m/s
So
[tex]0 = u - 9.8 * \frac{ 3.7}{2}[/tex]
=> [tex]u = 18.13 \ m/s[/tex]
Here u is the initial velocity of the dart as it leaves that gun
Gnerally the horizontal range of the dart is mathematically represented as
[tex]R = \frac{u ^2 sin 2\theta }{g}[/tex]
For maximum horizontal range the value of [tex]\theta = 45^o[/tex]
So
[tex]R_{max} = \frac{ 18.13 ^2 sin 2(45) }{9.8}[/tex]
=> [tex]R_{max} = 33.54 \ m[/tex]

Which factor leads to interference between waves? (2 points)
Select one:
a. A varying phase relationship between waves
b. Similar wave amplitudes
c. Unequal wavelengths
d. Radiation through different regions
Due to the sheer short wavelength, the angle at which constructive interference in between waves occurs is unequal wavelengths.
Unequal wavelengths:Two conditions must be met to create a steady and clear interference pattern: both wave sources must be cohesive, meaning they must emit identical waves with a consistent phase difference. The waves should be monochromatic, meaning that they will have only one wavelength.As a result, the interference between waves would be limited by unequal wavelengths.Find out more about the Unequal wavelengths here:
