Answer:
The answer is actually a. Cathode
Explanation:
Just took the quiz
In an electrolytic cell, the reduction occurs at the cathode. So, the correct option is a.
What is meant by reduction ?Reduction is defined as the process through which a reactant gain electrons during a chemical reaction.
Here,
An electrolytic cell is an equipment that uses electric current to drive a redox reaction.
Redox reactions are the type of reaction that involves the transfer of electrons between the reactants. That means, in redox reactions, both oxidation and reduction occurs. The reactant that gains the electrons is said to be reduced and the one that losses the electrons is said to be oxidized.
In an electrolytic cell, cathode is the positively charged electrode. So, electrons are attracted towards it, and as a result, the cathode gets reduced.
Hence,
In an electrolytic cell, the reduction occurs at the cathode.

Explanation:
A gun fires a bullet horizontally with a velocity of 90 m/s from a tower. Neglecting air resistance, how far will the bullet travel horizontally in 4 seconds?
Answer:
The distance covered along the horizontal axis is [tex]s = 360 \ m[/tex]
The distance covered along the vertical axis is [tex]h = 78.4 \ m[/tex]
Explanation:
From the question we are told that
The horizontal velocity is [tex]u_x = 90 \ m/s[/tex]
The time considered is [tex]t = 4 \ s[/tex]
Generally the distance which the bullet will cover in the horizontal direction for the given time is mathematically represented as
[tex]s = u_xt + \frac{1}{2}* at^2[/tex]
Here a is the acceleration along the horizontal direction and the value is [tex]a = 0 \ m/s^2[/tex]
So
[tex]s = 90 * 4 + \frac{1}{2}* * 0 * 4^2[/tex]
=> [tex]s = 360 \ m[/tex]
Generally the distance which the bullet will cover in the vertical direction for the given time is mathematically represented as
[tex]h= u_y t + \frac{1}{2}* gt^2[/tex]
Here [tex]u_y[/tex] is the initial velocity of the bullet along the vertical axis and the value is [tex]u_y = 0 \ m/s[/tex]
[tex]h = 0 * 4 + \frac{1}{2}* 9.8 *4^2[/tex]
=> [tex]h = 78.4 \ m[/tex]

A researcher changes the DNA in a soybean plant so that it produces offspring with a resistance to weed killer. Which best describes this scenario? genetic engineering gene therapy cloning selective breeding
Answer:
Genetic engineering
Explanation:
Genetic engineering or also called genetic modification is the direct manipulation of an organism's genome in order to bring about a desirable trait in such organism. In genetic engineering procedure, the organism manipulated is called TRANSGENIC or GENETICALLY MODIFIED (GM) organisms.
In this case, a researcher is said to change the DNA (genetic material) in a soybean plant so that it produces offspring with a resistance to weed killer. This describes a genetic engineering procedure in which the soybean plant is manipulated to yield a desired trait, which is resistance to weed killer.
Answer:

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

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

You are in a plane, and hit a bird as your flying, how can this impact produce a large impulse, despite the plane being much bigger
It effects the balance of the plane, and slows it. Also you are likely moving faster than the bird, and it would be almost as if you are hitting a brick. However when it makes the plane impulse then it means the sudden loss of speed (even if it is a small bird) that is keeping the plane in the air causes the planes engines to struggle for a short amount of time, while it tries to recover the little amount of speed it has lost (the engines HAVE to regain full speed or the plane will turn to the ground, maybe not ALL the way but it still will lower the nose.
Hope this helps,

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
