this is science but I for some reason the science wasnt showing
Answers
Answer:
Option C) Fluorine and Chlorine.
Explanation:
According to the given options; the two elements that have similar characteristics are Fluorine and Chlorine.
As both the elements belong to the same group in the periodic table which is the halogen group and they have the same valency although their reactivities differ. Fluorine is more reactive than chlorine if compared. They both are placed in the same group which is Group 7 in the modern periodic table. As both the elements have 7 electrons in their outermost shell.

Describe a ways car manufacturers try to reduce drag and why.
Answers
Aerodynamics is a way to reduce drag that uses car manufacturers.
What is aerodynamic ?
Aerodynamics is the motion of the air. airplane flies cause of aerodynamics.
Aerodynamics is the study of forces that are resulted by motion of the air.
To reduce the aerodynamic drag further, the manufacturers use character lines on the exteriors of the car's body right from its concept stage. These lines help the air to pass smoothly over the body and thus, reducing the air resistance.
cars have flat vertical face in front. When it moves through air, drag force directly proportional to the velocity applies on the car which opposes motion of the car. after studding aerodynamics when we make triangular like shape to the front body of the car, it cuts the air and front air goes from side of the car which reduces oppose to the motion, and car can have more speed.

What is the velocity of a freely falling object 10 seconds after it is released from rest?
Answers
Answer:
around 98 meters per second.
Explanation:
Instantaneous velocity can be found with a equation.
Vf=Vi+At
Since it fell and had no initial velocity the equation becomes
Vf=At
The Acceleration is 9.8 m/s^2
So the velocity of it fell for ten seconds is
Vf=9.8m/s^2 * 10
Vf= 98 m/s
A dog walks 21 m north and then walks 35 m west to bury a bone. What is the displacement of the dog?
Answers
Answer:
40.8 m North West.
Explanation:
Please see attached photo for diagram.
In the attached photo, R represent the displacement of the dog.
The displacement (R) of the dog can obtained by using the pythagoras theory as illustrated below:
R² = 35² + 21²
R² = 1225 + 441
R² = 1666
Take the square root of both side.
R = √1666
R = 40.8 m North West.
Therefore, the displacement of the dog is 40.8 m North West.

John can't describe a penny because he never learned what one looked like in the

John and Susan find a penny, and Susan says, "I bet you can't tell me what is on the penny". John's inability to describe the penny is an example of a failure to encode.
The ability to encode a piece of information is to be able to translate or explain the body of information at a later date or time. When John thinks about what is on the penny, he couldn't describe it because he never learned how to encode the information on the piece of the penny in the first place.
Retroactive interference is a process whereby fresh memories interfere with the recovery of old memories. This sort of interference has a retrograde impact rendering it more challenging to recall previously learned information.
On the other hand, proactive interference is a process whereby old memories interfere with the recovery of fresh new memories.
Therefore, we can conclude that since John has never learned what a penny looked like before, he doesn't have previous information about it. As such, the only correct option is (2)

A 2 kg object is moving at a constant velocity of 15 m/s. What is its acceleration?
Answers
Answer:
The acceleration of the object is 0 m/s^2.
Explanation:
To solve this problem, we must remember that acceleration is equal to the change in velocity per unit time. Since we are given that the velocity is constant, this means it is unchanging, and the acceleration is therefore zero.

Which is an example of static friction?
a. pulling a skier behind a boat
b. pushing a box that is at rest
c. braking a car going down a hill
d. driving a car up a hill
Answers
Answer:
static friction is developed between 2 surfaces in state of rest so i think answer is c.Even though the wheel is in motion, the patch of the tire in contact with the ground is stationary relative to the ground, so it is static rather than kinetic friction.
The static friction is the hindrance to an object which is trying to move from stationary state. Among the given options, the example for static friction is pushing the box that is at rest.
What is static friction?The friction that occurs when people attempt to move a stationary object on a surface without actually causing any relative motion between the body and the surface.
The static frictional force is self-regulating, which means that it will always be equivalent to and opposite to the force applied. Static friction is zero for an object at rest on a flat table.
Static friction creates an equal and opposite force that keeps the book at rest when you push horizontally with a small force.The static friction force increases to match the force as you push harder.
The maximum static friction force is eventually exceeded, and the book moves. Therefore, option B is correct.
