Which is a device that stores electric charge by separating positive and negative charges?

Answer:

60kgm/s

Explanation:

Given parameters:

Mass of frisbee  = 5kg

Final speed  = 12m/s

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

Answer:

the tides would be twice as big as they are now and the world would flood

Explanation:

The tides would be twice as massive as currently if moon was twice as massive  it is currently.

The tidal force is a gravitational effect that stretches a body along a line towards the center of mass of another body due to a gradient in the gravitational field from the other body.

A body stretches as a result of this disparity. As a result, in addition to being a byproduct of the gravitational field, the tidal force is also referred to as the differential force.

The nearest side is pulled more strongly than the farthest side because the gravitational field imposed on one body by another is not consistent across its portions.

As tidal force is a kind of gravitational force, it linearly depends on the mass of the moon. So, the tides would be twice as massive as currently if moon was twice as massive  it is currently.

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:

6 g/mL

Explanation:

given:

mass = 150g

volume = displaced volume of water = 25 mL

recall that density = mass / volume

density = 150g / 25 mL = 6 g/mL

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:

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: 21 kg x m/s

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:

New kinetic energy = 12 times of the initial kinetic energy.

Explanation:

The kinetic energy of an object is given by :

[tex]K=\dfrac{1}{2}mv^2[/tex]

Where

m is mass of the object

v is speed of the object

ATQ,

If the mass of the object is tripled, m' = 3m

Speed is doubled, v' = 2v

New kinetic energy will be:

[tex]K'=\dfrac{1}{2}m'v'^2\\\\K'=\dfrac{1}{2}\times 3m\times (2v)^2\\\\=\dfrac{1}{2}\times 3m\times 4v^2\\\\=12\times \dfrac{1}{2}mv^2\\\\K'=12\times K[/tex]

So, the new kinetic energy will become 12 times of the initial kinetic energy.

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..

The elastic potential energy is the energy stored within a string.

It is expressed as;

           EPE = [tex]\frac{1}{2}[/tex] k e²  

k is the spring constant

e is the extension

         4000  =  [tex]\frac{1}{2}[/tex] x k x 6²

Given parameters:

Final velocity of the bullet  = 720m/s

Distance covered  = 324m

Unknown:

Time for the bullet to strike a target = ?

Velocity in km/h

Solution:

To solve this problem, we use the kinematics equation shown below:

     S  =( [tex]\frac{v + u}{2}[/tex]) t

So;

        324  = [tex]\frac{720 + 0}{2}[/tex]  t

        324  = 360t

           t  = 0.9s

B. to convert this velocity to km/hr

       1000m  = 1km

       3600s  = 1hr

  720 x m x [tex]\frac{1}{s}[/tex]  x [tex]\frac{1km}{1000m}[/tex]  x [tex]\frac{3600s}{1hr}[/tex]    = 2592km/hr

Answer:

403.63

Explanation:

I'm assuming you were asking for the last question on the Calorimetry gizmo.

If the simple machine reduces the amount of force, what must be increased the size of the simple machine.

A force in physics is an effect that has the power to alter an object's motion. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

An object that transfers and alters force is a machine. Machines come in a variety of forms, such as incline planes, levers, wheel and axles, pulleys, and gears. • The mechanical advantage provided by a machine is the same as the output force. divided by the input force (load)

If the simple machine reduces the amount of force, what must be increased the size of the simple machine.

Answer: D=pg

Explanation:

?????

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.
