a) On which hemisphere does Bhutan lie on the earth?​

Explanation:

Wavelength is the distance between two consecutive and equivalent points on a wave. Wavelength can be quantified by measuring the distance between two equivalent and consecutive points, such as the distance between two peaks or two troughs. The scientific symbol for wavelength is a Greek letter called lambda.

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:

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]

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)

Answer:

yea, force is mass x acceleration

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.

Explanation:

Answer:

A

Explanation:

According to Newton's second law, acceleration is directly proportional to the net force. As the acceleration increases (when mass is constant), the net force increases. This is represented in the following formula.

[tex]f = ma[/tex]

[tex]a = \frac{f}{m} [/tex]

a = acceleration

f = force

m = mass

Answer:

Explanation:

Set the equations for work and kinetic energy equal to each other. Work equals force times distance and kinetic energy equals one-half the mass of the object times its velocity squared, so F_d = (m_ ÷ _2)_v2. Substitute the measurements for force, distance and mass into the equation.

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. Kinetic energy is the type of energy that is transferred and is dependent on the mass and speed attained.

The square of the object's velocity determines the kinetic energy. In other words, when an object's velocity twice, its kinetic energy quadruples.

Therefore, The energy an object has as a result of motion is known as kinetic energy.

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

Answer:

The correct option is;

B.) 2.0 m/s²

Explanation:

The given information are;

The masses of the boxes are; m₁ = 15 kg and m₂ = 10 kg

The force applied, F = 50 N

The friction force between the blocks and the table = N/A

The equation for the applied force, F = Mass, m × Acceleration, a

Therefore;

a = F/m

Given that the two boxes are attached to each other and to the force by a spring, they will experience the same motion, and therefore, the same acceleration

The total mass (the two blocks) pulled by the applied, 50 N force, [tex]m_T[/tex] = m₁ + m₂ = 10 kg + 15 kg = 25 kg

The acceleration given the blocks by the applied force, a = F/[tex]m_T[/tex] = 50 N/(25 kg) = 50 kg·m/s²/(25 kg) =  2 m/s²

The acceleration experienced by the 10 kg box = The acceleration experienced by the system of the two boxes = 2 m/s².

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.

Explanation:

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:

Work = force • distance

so (input) 400 • 6 = 2400 joules.

and (output) 500 • 4 = 2000 joules

and efficiency = output energy ÷ input energy

so 2000 ÷ 2400 = 83%

input energy = 2400 joules

output energy = 2000 joules

efficiency = 83%
