What type of reaction occurs when an egg cooks in a pan?

Answer: skeletal only

Explanation: Cardiac muscle (also called heart muscle or myocardium) is one of three types of vertebrate muscles, with the other two being skeletal and smooth muscles. It is an involuntary, striated muscle that constitutes the main tissue of the walls of the heart.

Smooth muscle is responsible for muscle tissue in which the contractile fibrils are not highly ordered, occurring in the gut and other internal organs and not under voluntary control.

Answer:

Inertia

Explanation:

Inertia is best defined as the ability of an object to resist a change in position or movement. That is why when an object has a higher mass, the higher the inertia. Imagine an oncoming truck that is fully loaded versus you. The tendency for the truck to change its movement would be difficult because of its its mass. It has a lot of inertia.

Answer:

An on-camera flash is an indispensible accessory for many photographers; it provides additional light when conditions become too dark to handhold your camera comfortably, allows you to achieve more balanced exposures in daylight conditions, permits freezing of fast-moving subjects and can also be used to control or trigger other flash light sources. Additionally, a flash can be used as a highly effective creative tool to establish an aesthetic that elevates your imagery when lighting conditions are considered less than stellar. The benefits of an external on-camera flash far outweigh those provided by a built-in camera flash, while the only drawback is keeping an additional piece of equipment.

On-Camera Flash versus Off-Camera Flash versus In-Camera Flash

The term on-camera flash simply refers to a type of strobe light (flash) that can connect directly with your camera. While it is referred to as “on-camera” this does not require the flash to be physically mounted on your camera. On-camera flashes can, and often are, used off-camera. This differs from other strobe-light sources, such as studio pack strobes and monolights in that these types of strobes are not meant to be physically connected to your camera (except under rare and unusual circumstances involving convoluted methods of adaptation). Additionally, on-camera flashes usually have a self-contained power supply, although external power sources can sometimes be used to improve performance or battery life.

On-camera external flash also refers to the type of external flash that can be used on your camera, compared to a built-in flash that is integrated into many cameras. An on-camera external flash performs better than a built-in flash in almost every regard with the one exception that it is not built into your camera. The ability to take the flash off your camera results in a significantly greater number of lighting options; far more than simply providing a blast of flat light to the scene to facilitate an adequate exposure. It is often not desirable to have your flash pointed squarely at the scene at hand; more often than not you will want to bounce the flash light off other surfaces and point in other directions to control the look of your flash. When using an in-camera flash, you are forced to use the flash at the given angle from which it extends.

Most built-in flashes are also located near the camera lens, which can often result in the red-eye effect  when photographing subjects in dimly lit conditions. Red-eye occurs because pupils dilate in dim light, the built-in flash is aligned with the lens's optical axis, its beam enters the eye and reflects back at the camera from the retina at the rear of the eye, which is quite red. Being able to use an on-camera flash source off-camera, from a different angle, will help to eliminate the red-eye effect in your photographs of people.

Guide Numbers, Manual Usage, Controlling Flash Power and Sync Speeds

Before delving into the automatic technology that is contained within most contemporary flashes, it is best to understand how to manually control and grasp a flash’s power. This is directly related to having an understanding of exposure ratios—how shutter speeds and apertures affect and balance each other—even though auto-exposure metering is available and often utilized for determining the best exposure settings.

Answer:

A. Remove everything in the refrigerator to lighten the load.

B. Put a lubricant between the surface of the object and the floor

C. Use round objects, like pencils , to decrease the friction and push the refrigerator over the pencils more easily

Explanation:

Force of friction is a resistance force which acts between two surfaces which are in relative motion. Friction is both boon and bane. Due to friction, we are able to sit, walk etc but also, due to friction there is dissipation of energy. Friction can be reduced by applying lubricants, reducing contact area, reducing the load.

F = μN where N is the normal force which depends on the mass.

Thus, by reducing the load, force of friction can be reduced. Round objects like wheels can also be used. By this the contact area reduces.

Explanation:

Answer with Explanation:

When solving a problem in math, chemistry or physics, it is necessary to understand all the words and their definitions.  If not, start with finding out their meanings, one by one.

Here the key word to know is pascal, (P), which is a unit of measure for pressure, defined as

pressure = Force / applied area

1 pascal = 1 newton / square metre or

1 P = 1 N/sq.m.

Here, we have been given:

Force = 150 N

Area = 0.25 m^2.

Thus the pressure

= Force / Area

= 150 N / 0.25 m^2

= 150/0.25  N/m^2

= 600 pascals.

The acceleration which is gained by an object because of gravitational force is called its acceleration due to gravity. Its SI unit is m/s2. Acceleration due to gravity is a vector, which means it has both a magnitude and a direction. The acceleration due to gravity at the surface of Earth is represented by the letter g. It has a standard value defined as 9.80665 m/s2.[ However, the actual acceleration of a body in free fall varies with location. (Wikipedia)

The acceleration due to gravity is  9.89 m / s2.

Explanation:

Gravity was discovered by Newton when he was sitting under a tree and was watching an apple reaching the ground instead of going upwards. He fond that there is a gravitational pull attached to the ground of the earth which makes all the objects towards the ground. It is represented by 'g' and its value is equal to 9.8 m /s2.

Elastic potential energy stored in bungee cord is 20.0 J.

Answer: Option B

Explanation:

The elastic potential energy is a form of potential energy stored in elastic materials. Generally potential energy is the energy of any object when it is at rest. But in materials possessing elastic properties, they store these potential energy in the form of elastic potential energy and it is used when the elastic materials undergoes elastic deformation.

For example, if we consider a spring, the elastic potential energy of the spring will be zero, when it is not deformed elastically i.e., when the spring is not stretched or compressed. But the same spring will be exhibiting elastic potential energy when the spring is stretched or compressed. So, the formula for elastic potential energy is

      [tex]\text { Elastic potential energy }=\frac{1}{2} \times \text { spring constant } \times\left(\frac{\text {stretching}}{\text {compressing distance}}\right)^{2}[/tex]

In this case, as the spring constant of cord is given as 10 N/m and the stretching distance of the cord is given as 2 m, so the elastic potential energy stored in the cord will be

       [tex]\text { Elastic potential energy }=\frac{1}{2} \times 10 \times(2)^{2}=\frac{1}{2} \times 10 \times 4 = 20 J[/tex]

How does the thickness of the wire affect the strength of an electromagnet?

Answer:

How does the thickness of the wire affect the strength of an electromagnet

Explanation:

Generally, electromagnet strength increases with an increase in wire thickness. From the theory of electric circuit, the resistance of an electric wire is inversely proportional to the cross sectional area of the electric wire. Mathematically, we have:

R ∝ 1/A

Where:

R is the resistance of the electric wire; A is the cross sectional area of the wire. Therefore, for a large cross sectional area, the resistance will be very low, and the electric current passing through the electromagnet will be high. This will create a very high magnetic field. Thus, the question that Maya will most likely answer is: How does the thickness of the wire affect the strength of an electromagnet.

You are going to lift and press down on the 200 N many times and move only a short distance. The reward is that slowly but surely you will lift a very heavy load -- one that cannot be managed any other way but by the hydraulic jack.

Explanation:

Given:

v₀ = 15 m/s

a = 3.5 m/s²

t = 5.0 s

Find: v

v = at + v₀

v = (3.5 m/s²) (5.0 s) + 15 m/s

v = 32.5 m/s

The final velocity of the car, after accelerating at a rate of 3.5 m/s^2 for 5 seconds from an initial velocity of 15 m/s, is 32.5 m/s.

The car's final velocity can be calculated using the formula for acceleration: final velocity = initial velocity + (acceleration x time). Here, the initial velocity is 15 m/s, the acceleration is 3.5 m/s^2, and the time is 5.0 seconds.

Substituting these values in the formula gives: final velocity = 15 m/s + (3.5 m/s^2 x 5.0 seconds) = 15 m/s + 17.5 m/s = 32.5 m/s. So, the car's velocity after 5 seconds of accelerating at a rate of 3.5 m/s^2 is 32.5 m/s.

Answer: Hydrogen gas produced during a reaction

Explanation:

A chemical lab is a place where potential hazards oriented to the use of the chemicals can happen. These chemicals can cause injuries to the skin when come in contact directly or indirectly. Therefore, protective safety measures should be taken so as to protect oneself while working in a chemical lab.

Among the options given, hydrogen gas produced during a reaction is the correct option. This is because of the fact that close-toed shoes can provide protection against all types of chemical fluids. But the gases like hydrogen gas are reactive and they are permeable inside the shoe material hence, may cause damage.

In fact, all particles (atoms and molecules) in nature contain an equal number of protons (plus charged basic particles) and electrons (minus charged basic particles). Therefore, it is natural that the particles are uncharged.

The positively charged particles within the nucleus of an atom are protons. So, the correct option is B. Protons. Protons carry a positive charge while neutrons within the nucleus are neutral.

The positively charged particles within the nucleus of an atom are protons. Protons carry a positive charge that is exactly equal in magnitude to the negative charge carried by electrons. In a neutral atom, the number of protons in the nucleus is balanced by the same number of electrons outside the nucleus. It is important to note that neutrons, which are also located in the nucleus, carry no charge (they are neutral).

To summarize the particles in the nucleus:

Protons: Positively charged

Neutrons: Neutral (no charge)

Answer:

55.3 N, 223.3 N

Explanation:

First of all, we can find the angle of the inclined plane.

We have:

L = 5 m the length of the incline

h = 1.2 m is the height

We also have the relationship

[tex]h = L sin \theta[/tex]

where [tex]\theta[/tex] is the angle of the incline. Solving for the angle,

[tex]\theta= sin^{-1} (\frac{h}{L})=sin^{-1} (\frac{1.2 m}{5 m})=13.9^{\circ}[/tex]

Now we can find the components of the weight of the box, which is the force that the box exerts on the plank. Calling W = 230 N the weight of the box, we have:

- Component parallel to the incline:

[tex]W_{par} = W sin \theta = (230 N)(sin 13.9^{\circ}) =55.3 N[/tex]

- Component perpendicular to the incline:

[tex]W_{per} = W cos \theta = (230 N)(cos 13.9^{\circ}) =223.3 N[/tex]

For this case we have by definition, that the Ampere, is the unit of electric current intensity.

For its part, the electric current is a measure of the velocity at which the electric charge flows.

The symbol of the current is A. We have that 1 Ampere is equivalent to an electric charge of a coulomb per second.
