When you walk across the ground and push on it with your feet...
Group of answer choices
The ground pushes back more strongly than your feet
The ground pushes back on your feet with equal force
There is no effect on the ground
The ground pushes back less strongly than your feet
Answer:
The ground pushes back on your feet with equal force
Explanation:
When you walk across the ground and push on it with your feet, the ground pushes back on your feet with an equal and opposite force.
This interpretation and knowledge is gotten from Newton's third law of motion.
It states that "action and reaction force are equal and opposite in nature".
The force applied to a body responds with an opposite force in the other direction. Therefore, the reaction force is of equal magnitude but directed in another direction.Answer:
the answer is the second one: the ground pushes back on your feet with equal force

Solve for X, please help!!
Answer:
x=12
Explanation:
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
Which one of the 4 answers is it?
the stolen valor act
Answer:
The Stolen Valor Act of 2005, signed into law by President George W. Bush on December 20, 2006, was a U.S. law that broadened the provisions of previous U.S. law addressing the unauthorized wear, manufacture, or sale of any military decorations and medals. The law made it a federal misdemeanor to falsely represent oneself as having received any U.S. military decoration or medal. If convicted, defendants might have been imprisoned for up to six months, unless the decoration lied about is the Medal of Honor, in which case imprisonment could have been up to one year. In United States v. Alvarez, the U.S. Supreme Court ruled that the Stolen Valor Act was an unconstitutional abridgment of the freedom of speech under the First Amendment, striking down the law in a 6 to 3 decision.
Explanation:
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.
Word Bank:
static
sliding
rolling
bumpy
heavy
easier
greater
Answer:
1. Static friction = not moving
2. sliding friction = moving
3. rolling friction = wheels
4. bumpy the surfaces are
5. how heavy the object is

A. stored energy
B. future energy
C. kinetic energy
D. invisible energy
Answer:
c
Explanation:
Form hypothesis: How do you think increasing the resistance in a circuit will affect the current in the wire? (format: if, then, because)
Answer:it would make it thicker
Explanation:
Answer:
"The equation shows that the current in a circuit is inversely proportional to the resistance of the circuit. An increase in resistance would result in a decrease in current. And the factor by which the resistance increases is the same factor by which the current decreases."
Explanation:
Because it's just like wearing a glove/mitten when getting something out of the oven, because of the insulation from the glove/mitten, it reduces the heat that gets through into your hand, and it protects it. Just like what the "answer" says, it said that the resistance would decrease current.
state 8/15 as a decimal correct to four decimal places
Answer:
8/15=0.53..., since the 3 is repeating, just stop at the 4th decimal place, thus
0.5333
Explanation:
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.

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.

What role do electromagnets play in making a motor spin?
Answer:
I'm going to try to explain it to you easy as possible so basically when a motor is placed between two poles of another magnet a current from a voltage flow to the coil and a magnet field is produced around the electromagnetic and the poles of the magnet interact with the poles from the electricmatic causing the motor to turn in more coils growing stronger into the motor

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:
