Answer:

people's reactions and perceptions to stimuli.

Explanation:

Psychophysics can be defined as the scientific study of people's reactions and perceptions to stimuli.

Stimulus can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). Thus, all living organisms (humans) respond to changes in their environment and consequently, an appropriate response or reaction is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.

In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ.

Hence, psychophysics is a branch of psychology and it is typically focused on determining the effects of stimuli on the mental health or processes of humans.

Answer:

study of people's reactions and perceptions to a stimulus.

Explanation:

Before the emergence of psychology, psychophysics was the more common practice. Psychophysics is the study of people's reactions and perceptions to a stimulus. For example, when you hear a bell ring, do you act startled, blink your eyes, turn your head, or do nothing? Psychophysicists were interested in people's five senses and how those senses responded to stimulation from elsewhere. Tests were administered to people to try to understand mental phenomena.Psychophysicists wanted to know what people's reactions would be. For example, if a bell rang twenty times, how well did a person hear that sound and did the person find that sound pleasant?

Answer:

If an object is at rest, then there are no forces acting upon the object.

Explanation:

It would take an unbalanced force to keep an object in motion at a constant velocity. It is the natural tendency of all objects to eventually come to a rest position.

Answer: 5km per hour

If the train is going 25km in 5 hours, you can figure out how many kilometers per hour it is traveling by dividing 25km by the 5 hours.

Answer:

45000kgm/s due east

Explanation:

Given parameters:

Mass of the car  = 1.5 x 10³kg

Velocity  = 30m/s

Time taken  = 60s

Unknown:

Momentum  = ?

Solution:

Momentum is the quantity of motion a body possess,

     Momentum  = mass x velocity

So;

  Momentum  = 1.5 x 10³ x 30  = 45000kgm/s due east

Answer:

The spring constant is k=7031.25

Explanation:

We start by using the conservation of mechanical energy:

Ui + Ki = Uf + Kf

the Ui (initial potential energy) is zero since the spring is relaxed.

In the final situation, the Kf (final kinetic energy is zero since the car and spring are NOT in motion)

Then we have:

[tex]K_i=U_f\\\frac{1}{2} m*v^2=\frac{1}{2} k*(\Delta x)^2\\\frac{1}{2} 2000*15^2=\frac{1}{2} k*(8)^2\\k=7031.25[/tex]

15 mm Hg is the guage pressure of an object with a mass of 30 kg and 5ft height.

The measurement of pressure in relation to atmospheric pressure is known as gauge pressure. The zero point for this pressure measurement is set at 1 atm. With relation to atmospheric pressure, pressure is measured.

When a car climbs a mountain, the gauge pressure rises as the air pressure falls, but the tire's absolute pressure stays the same, assuming no tire leaks.

guage pressure = mass×height

                          = 30×5

                         =15 mm Hg

Therefore, 15 mm Hg is the guage pressure of an object with a mass of 30 kg and 5ft height.

Momentum can be found using the equation p = mv, or momentum = mass times velocity.

Therefore, to find the momentum of the bowling bowl, you can plug the mass and velocity values into the equation to get p = (7kg)(3m/s)

Solve the equation to get a momentum of 21kg x m/s

Answer:

[tex]\boxed {\boxed {\sf v \approx 33.088 \ mL}}[/tex]

Explanation:

The formula for density is:

[tex]d= \frac{m}{v}[/tex]

where m is the mass and v is the volume.

The mass is 0.45 kilograms and the density is 13.6 grams per milliliter. The density is given in grams, so we must convert the mass.

There are 1000 grams in 1 kilogram or [tex]\frac{1000 \ g} {1 \ kg}[/tex]. We can multiply the mass by this ratio.

[tex]0.45 \ kg * \frac{1000 \ g} {1 \ kg} = 0.45 * 1000 \ g = 450 \ g[/tex]

Now we have values for the mass and density:

[tex]13.6 \ g/mL =\frac{450 \ g}{ v}[/tex]

Cross multiply.

[tex]\frac {13.6 \ g/mL}{1} =\frac{450 \ g}{ v}[/tex]

[tex]13.6 \ g/mL * v=450 \ g * 1 \\13.6 \ g/mL * v=450 \ g[/tex]

We are trying to find the volume, so we must isolate that variable.

13.6 and v are being multiplied. The inverse of multiplication is division. Divide both sides by 13.6

[tex]\frac {13.6 \ g/mL*v } { 13.6 \ g/mL} = \frac{ 450 \ g} {13.6 \ g/mL}[/tex]

[tex]v= \frac{ 450 \ g} {13.6 \ g/mL}[/tex]

The grams will cancel.

[tex]v= 33.0882353 \ mL\\v \approx 33.088 \ mL[/tex]

The volume is about 33.088 milliliters.

Answer:

A sea star that has the ability to regenerate amputated limbs must first undergo a repair phase to heal the exposed wound. Once the wound is healed, the sea star can begin to generate new cells, which in turn, sparks new growth. Regeneration can take anywhere from several months to years. Reproduction: Sea stars are broadcast spawners. Males release sperm into the water and females release eggs. The fertilized eggs hatch into a larval form that lives as plankton, sometimes for months, before settling on the sea floor in its adult form..

Answer:

Explanation:

Given parameters:

Area of the book cover  = 0.05m²

Atmospheric pressure  = 100kPa  = 100 x 10³Pa

Unknown:

Downward force of the atmosphere on the book  = ?

Solution:

Pressure is defined as the force per unit area on a body.

 So;

 Downward force  = Atmospheric pressure x Area

  Downward force  = 100 x 10³ x 0.05  = 5000N

Answer:

a = 30 [m/s²]

Explanation:

To solve this problem we must use Newton's second law, which tells us that the sum of forces on a body is equal to the product of mass by acceleration. In this way, we have the following equation.

∑F = m*a

where:

m = mass = 2.5 [kg]

a = acceleration [m/s²]

F = force = 75 [N]

Now replacing:

[tex]75=2.5*a\\a=75/2.5\\a=30[m/s^{2} ][/tex]

Answer:

magnitude of v = 2.5 m/s, and in the same direction as the initial velocity of the 5 kg ball.

Explanation:

We use conservation of linear momentum in an elastic collision to solve for the unknown velocity v:

Pi = Pf

5 kg * 5 m/s + 10 kg * 0 m/s = 5 kg * 0 m/s + 10 kg * v

25 kg m/s = 10 kg * v

v = 25/10 m/s

v = 2.5 m/s

and in the same direction as the initial velocity of the 5 kg ball.

Unknown:

Impulse of the frisbee  = ?

Solution:

The impulse of the frisbee is the same as the change in momentum.

It is given as:

 Impulse  = mass (Final velocity  -  Initial velocity)

 Impulse  = 5(12  - 0)  = 60kgm/s

Energy can neither be created nor destroyed. It can be converted from one form to another. The total energy before and after conversion remains the same. The Law of Conservation of Energy is universal.

The law of energy conservation says that energy can be transformed from one type to another type, for example, if a ball is thrown upward the kinetic energy as the ball goes upward decreases, and the potential energy increases.

Energy conversion is the process by which energy is changed from forms supplied by nature to forms used by people.

For this goal, a huge variety of tools and systems have been created over the years. A few of these energy converters are really straightforward. Early windmills, for instance, used wind's kinetic energy to drive machinery that pumped water and ground grain.

A body's kinetic energy was thought to be transformed into potential energy as it slowed down while moving upward against the pull of gravity.
