Describe how you would draw a diagram that shows the electric field between two particles that
attract each other.

Answer:

Energy

Explanation:

One ways of stating the law of conservation of energy is that "you cannot get more energy from a machine than the amount of energy you put into it".

The law of conservation of energy states that in a system, energy is neither created nor destroyed but transformed from one form to another.

The energy in a system does not increase based on the premise of this law.

Signs look, listen, feel and smell for any signs of injury such as swelling, deformity, bleeding, discolouration or any unusual smells. When checking them you should always compare the injured side of the body with the uninjured side. Are they able to perform normal functions such as standing or moving their limbs

Secondary assessments are used in order to determine the injury, how the injury occurred, how severe the injury is, and to eliminate further injury.

Explanation:

Given parameters:

Mass  = 20kg

Speed  = 10m/s

m is the mass

v is the speed

 Now insert the parameters and solve;

     K.E  =  [tex]\frac{1}{2}[/tex]  x 20 x 10²   = 1000J

Answer:

2000N

Explanation:

Given parameters:

Acceleration  = 2m/s²  

Unknown:

The net force exerted on the car  = ?

Solution:

From newtons second law of motion;

     F =  mxa

F is the net force

m is the mass

a is the acceleration

       F = 1000 x 2 = 2000N

Answer:

This is true

Explanation:

This is true because in other To measure the potential difference that is across a circuit, we have to place the device called the voltmeter to be in parallel withe the circuit, so as to get a measurement of the difference in energy from one side of the circuit to the other side. We can also refer to the Potential difference as the voltage and it is measured in volts using a voltmeter

Answer:18/2

Explanation:

its half

Answer:

1)

Acceleration (a)=change in velocity/ change in time

Velocity (v)=90m/s

Time=0.0005s

a=90/0.0005

The acceleration =180000m/s^2 or 180km/s^2

Force = mass x acceleration

m=40g= 0.04kg

F= 0.04x 180000

F= 7200N or 7.2kN

Answer:

Educational institutions can influence what psychological perspectives are taught, studied, and researched. Take, for example, behaviorism. Before the cognitive perspective re-emerged, behaviorism was the dominant perspective being taught in most universities. Personal ideology can also affect which perspective a psychologist supports, the course of research a psychologist undertakes, and also a psychologist's perception and interpretation of research findings. For example, during the dominance of behaviorism, psychologists were discouraged from studying cognitive processes. As a result, much of the research conducted had a behaviorist slant to it.

Answer:

The Kinetic energy and mass are _directly_ proportional.

Explanation:

We know that Kinetic Energy is basically termed as the capacity of a body to do work.

Kinetic energy is often used to associate with moving objects, therefore, K.E is normally termed as the energy of motion.

The formula of K.E of an object of mass and velocity is defined

K.E = 1/2mv²

From the formula, it is clear that K.E is directly proportional to its mass and also directly proportional to the square of its velocity.

For example,

If A toy plane with a mass of 10 kg is flying at 20 m/s. Its K.E will be:

K.E = 1/2mv²

      = 1/2(10)(20)²

      = 1/2(10)(400)

       = 5(400)

      = 2000 J

Now, let suppose, if we double the mass of a toy plane i.e.

m = 20 kg

so

K.E = 1/2mv²

      = 1/2(20)(20)²

      = 1/2(20)(400)

      = 10(400)

      = 400 J

Therefore, the K.E is doubled when doubled the mass.

Therefore, the Kinetic energy and mass are _directly_ proportional.

Answer:

0.141Hz

Explanation:

Given parameters:

Velocity of the wave  = 1.7m/s

V is the velocity

F is the frequency

∧ is the wavelength

 Now insert the parameters and solve;

           1.7  = F x 12.05

            F  = 0.141Hz

Answer:

D. 0.60 um

Explanation:

Given the following data;

Frequency = 5.0x10^14 Hz

Speed = 3 x 10^8 m/s

To find the wavelength;

Wavelength = speed/frequency

Substituting into the equation, we have

Wavelength = 3 x 10^8/5.0x10^14

Wavelength = 6 × 10^7m

But 1 meter (m) = 1000000 micrometer (um)

6 × 10^7 meter = 0.6 micrometer.

Formula for kinetic energy:

K = ½mv²

Given:

v = 1.4 m/s

m = 71 kg

K = ½ · 71.0 kg · (1.4 m/s)²

K = 35.5 kg · 1.96 m²/s²

K = 69.58 J

Answer:

20N

Explanation:

Given parameters:

Mass of the block  = 4kg

Acceleration  = 5m/s²

The speed of the block after the student pushes it is 10m/s.

Given the data in the question;

Since the block is initially at rest,

Final velocity; [tex]v =\ ?[/tex]

To determine the final velocity; we use the First Equation of Motion:[tex]v = u + at[/tex]

Where v is final velocity, u is initial velocity, a is acceleration and t is time taken.

We substitute our values into the equation

[tex]v = 0 + [ 2m/s^2\ *\ 5s]\\\\v = 2m/s^2\ *\ 5s\\\\v = 10\frac{ms}{s^2}\\\\v = 10m/s[/tex]

Therefore, the speed of the block after the student pushes it is 10m/s.
