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.

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:

Explanation:

To solve this problem, isolate the term of x from one side of the equation.

5x-2=3 and -5+4y=9

First, 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

First, 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.

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.

Answer:

25N

Explanation:

100 - 75 = 25

That should be right if im not dumb...

The resultant of the given forces will be "25 N".

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.

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

Explanation:

For a detected wave that is 15 meters long and 2.4 meters high and travel a distance of 75.0 meters in 30 seconds, the amplitude, speed, period, and frequency is mathematically given as

V=2.0m/s

A=1.2m

f=0.13Hz

T=7.5sec

The amplitude of the wave is the distance from the middle to the crest or through

Hence

Amplitude=wave height/2

A=2.4/2

A=1.2m

Generally, the equation for the speed  is mathematically given as

V=d/t

V=75/30

V=2.0m/s

Period time to complete one oscillation or length.

T=d/v

T=15/2

T=7.5sec

Answer:

Explanation:

The kinetic energy is the energy of motion.

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.

momentum of box moving east: 52 * 9 = 468 kg-m/s east

momentum of box moving west:  49 * 7 = 343 kg-m/s west

so finally moving towards, 468 - 343 = 125 kg-m/s east

Answer:

x = 45 [m]

Explanation:

To solve this problem we must use the following kinematics equation:

[tex]v_{f}^{2} = v_{i}^{2}-(2*a*x)[/tex]

where:

Vf = final velocity = 0

Vi = initial velocity = 15 [m/s]

a = desacceleration = 2.5 [m/s^2]

x = distance [m]

Note: the negative sign in the equation above, is because the car slows down.

0^2 = 15^2 - (2*2.5*x)

2*2.5*x = 15^2

x = 45 [m]

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.
