A ball is dropped and falls
Answer:
yeth
Explanation:
When you drop the ball, gravity pulls it down and it picks up speed. It hits the ground and squashes at the moment of impact. As the squashed ball springs back to its original shape, it pushes on the floor and the floor pushes back. The force of the floor pushing against the ball throws the ball back up into the air.

What is kinetic energy? (99 points)
A.thermal energy
B.the energy of radiation
C.stored energy
D.the energy of motion
Answer:
its D
Explanation:
The kinetic energy is the energy of motion.
What is kinetic energy?
The energy an object has as a result of motion is known as kinetic energy. A force must be applied to an object in order to accelerate it. We must put in effort in order to apply a force. After the work is finished, energy is transferred to the item, which then moves at a new, constant speed.
An item in motion has energy, which is called kinetic energy. Motion in space, you walking down the street, and the rotation of the planet around the sun are all examples of kinetic energy. Kinetic energy has the following formula: K.E. = 1/2 m*v², where m is the object's mass and v is its square velocity.
Any object in motion is using kinetic energy, so the energy of motion is
kinetic energy.

A bullet of mass 20g is horizontally fired with a velocity of 150m/s from a pistol of mass 2 kg. What is the
recoil velocity of the pistol?
Answer:
m1 = 20g (= 0.02 kg)
Mass of pistol, m2 = 2 kg
Initial velocity of the bullet (u1) and pistol (u2) = 0
Final velocity of the bullet, v1 = +150m s-1
Let v be the recoil velocity of the pistol.
Total momentum of the pistol and bullet after it is fired is
= (0.02 kg x 150 m s-1) + (2 kg x v m s-1)
= (3 + 2v) kg m s-1
Total momentum after the fire = Total momentum before the fire
3 + 2v = 0
→v = -1.5 m/s

4. Dr. Copus is in charge of the cognition department at the University of Wisconsin-Madison. A new drug named Mem-Reen has become available that might be able to improve people's memories. Dr. Copus puts half of her existing patients on the drug for two weeks while giving the other half of her patients a placebo (a fake drug). She then gives both groups a memory test and compares the scores. Afterwards, Dr. Copus analyzes the scores to determine if the memory drug worked. Independent Variable: _____________________________ Dependent Variable: ___________________________________ Experimental Group: _______________________________ Control Group: _________________________________________ 3 constants: ____________________________________________________________________________________________________________
Answer:
See the answer below
Explanation:
Independent variable: Type of drug (Mem-Reen or placebo)
Dependent variable: memories
Experimental group: The group that was given Mem-Reen
Control group: The group that was given placebo
Constants: Food, hours of sleep, memory test procedures.
The independent variable is an input variable that produces effects on the dependent variable. As the variable is changed, it produces different effects on the dependent variable.
The dependent variable is the actual variable that is measured during an experiment. It is the main purpose of setting-up of an experiment.
The experimental group is also referred to as the treatment group while the control group is the group that does not receive treatment at all or they receive fake treatment/placebo.
Constants are unchanging variables included in experiments. They remain unchanged both in the treatment and the control group, otherwise, the outcome of the experiment will be unreliable.
What effect charged objects have on uncharged objects
Answer:
Uncharged objects: In spite of what the standard says, an uncharged object will not be attracted or repelled from a charged object. Instead, the charged object will cause the uncharged object to become charged, with a positive charge on one side and a negative charge on the other side. This process is called induction.

5x-2=3 -5 + 4y = 9 solve the system of equiations
Answer:
[tex]x=1,y=\frac{7}{2}[/tex]
Explanation:
Given the following question:
[tex]5x-2=3[/tex]
[tex]-5+4y=9[/tex]
To solve a system of equations we must start by solving the first equation for x, and then we substitute the value of x in in the second equation and then solve for y to find the value of both variables.
[tex]5x-2=3[/tex]
[tex]-5+4y=9[/tex]
[tex]-2+2=0[/tex]
[tex]3+2=5[/tex]
[tex]5x=5[/tex]
[tex]5x\div5=x[/tex]
[tex]5\div5=1[/tex]
[tex]x=1[/tex]
Substitute and solve the second equation:
[tex]x=1[/tex]
[tex]-5+4y=9[/tex]
[tex]-5+5=0[/tex]
[tex]9+5=14[/tex]
[tex]4y=14[/tex]
[tex]4y\div4=y[/tex]
[tex]\frac{14}{4} =\frac{7}{2}[/tex]
[tex]y=\frac{7}{2}[/tex]
Your answers are "x = 1, and y = 7/2."
Hope this helps.
Answer:
x=1 and y=7/2Explanation:
To solve this problem, isolate the term of x from one side of the equation.
5x-2=3 and -5+4y=9
5x-2=3First, add by 2 from both sides.
5x-2+2=3+2
Solve.
3+2=5
Rewrite the problem down.
5x=5
Divide by 5 from both sides.
5x/5=5/5
Solve.
5/5=1
x=1
-5+4y=9First, add by 5 from both sides.
-5+4y+4=9+5
Solve.
9+5=14
4y=14
Divide by 4 from both sides.
4y/4=14/4
Solve.
14/2=7
4/2=2
Rewrite as a fraction.
y=7/2
Dividing is another option.
7/2=3.5
y=7/2
Therefore, the correct answer is x=1 and y=7/2.

What is the resultant of a pair of forces, 100N, upward and 75N, downward?
Answer:
25N
Explanation:
100 - 75 = 25
That should be right if im not dumb...
The resultant of the given forces will be "25 N".
Force:Another element applies a force on one component. This same concept of a force isn't restricted to living as well as non-living entities.
All objects can exert a force towards or against another item, as well as all objects might well be impacted by pressures.
According to the question,
The pair of forces,
Upward = 100 N
Downward = 75 N
Now,
The resultant pair will be:
= [tex]100-75[/tex]
= [tex]25[/tex] N (Upward)
Thus the response above is the appropriate.

A man is crossing a river of width 100 m on a motorboat. The velocity of the motor boat is 4 m/s eastward and the velocity of the water current is 3 m/s northward. What is the resultant velocity of the boat and how much time will it take for the man to reach the other shore of the river?
Answer:
The resultant velocity of the boat = 5 m/s
The time it will take for the man to reach the other shore of the river = 25 s
Explanation:
width of river = 100 m
The velocity of the motorboat = 4 m/s eastward
The velocity of the water current = 3 m/s northward
The resultant velocity of the boat is:
R^2 = 4^2 + 3^2
= √ (4^2) + (3^2)
= √16 + 9
=√25
= 5 m/s
The time it will take for the man to reach the other shore of the river is:
d = 100 m
v = 4 m/s
t = d / v
t = 100 / 4
t = 25 s
1. If d = 25 m and t = 10 s, what is v?
Answer:
velocity = displacement /time
v= d/t
v= 25/ 10
v = 2.5 m/s
