Answer:

Gamma radiation.

Explanation:

Electromagnetic waves are waves produced with respect to the interaction of electric field and magnetic field. They can be arranged with respect to their increasing or decreasing wavelength to form a pattern called electromagnetic spectrum.

Gamma radiation can be used for sterilization purpose due to the fact that it has a relatively high amount of energy, and do not produce any characteristic radiation.

Explanation:

Through Snell's Law, we can solve this.

The formula is:

n1 * sin(theta1) = n2 * sin(theta2)

n1 = flint = 1.66

n2 = water = 1.33

theta1 = 26.0°

theta2 = angle of refraction

Substituting these values in the formula,

1.66 * sin(26) = 1.33 * sin(x)

[1.66 *sin(26)] ÷ 1.33 = sin( x )

0.5471 = sin(x)

arcsin(0.5471) = x

33.17 = x

Therefore, the angle of refraction is 33.17°

b.) Using the same formula, we have:

1.66 * sin(x) = 1.33 * sin(90)

sin(x) = [1.33 * sin(90)] ÷ 1.66

sin(x) = 0.8012

x = arcsin(0.8012)

x = 53.2453°

Therefore, the light needs to have an angle of incident of 53.2453° in order to have a 90° angle of refraction.

Answer:

Stairway.

Explanation:

The steps that lead you from dependence to independence are referred to as the stairway to Lifetime Fitness, Health, and Wellness.

This ultimately implies that, these stairway or steps are very important and essential for all humans who seek Lifetime Fitness, Health, and Wellness.

A good health can be defined as the state of well-being (wellness) in which all of the components of an individual's health are balanced. These state of wellness comprises of six (6) important components and they are;

1. Physical: this is a measure of the state of an individual's body or the way the body functions. It is enhanced by eating right, working out or exercising, avoiding drugs and alcohol, maintaining a good body mass index etc.

2. Emotional: this deals with the state of an individual's mind being void of worries, negativity etc.

3. Social: this involves keeping a good relationship with friends, family and many others around.

4. Environmental: it deals with maintaining a hygienic surrounding, that is devoid of pollutants.

5. Mental or intellectual: avoiding unnecessary stress and anxiety while dealing or coping with the realities of life.

6. Spiritual: it encompasses belief systems, values, ideals, morality etc.

Hence, when an individual is able to balance all of these above mentioned components, then he or she is said to be healthy.

Answer:

Height.

Explanation:

Potential energy can be defined as an energy possessed by an object or body due to its position.

Mathematically, potential energy is given by the formula;

[tex] P.E = mgh[/tex]

Where,

P.E represents potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per seconds square.

h represents the height measured in meters.

Hence, the property of the object (having a mass of 5 kilograms) which must differ to have different gravitational potential energies is the height from which they are falling from.

The object having the higher height would have a greater gravitational potential energy than the lower object.

A 40-kg person is climbing 3 m up a flight of stairs in 6 seconds. How much work did they do climbing the stairs? answer choices . 400 J. 1200 J. 200 J. 120 J. Tags: Question 13 . SURVEY . 30 seconds . Report an issue . Q. A 40-kg person is climbing 3 m up a flight of stairs in 6 seconds. How much power did they exert climbing the stairs? answer choices . 400 W. 1200 W. 200 W. 120 W. Tags

200 W was used in climbing the stairs.

We'll begin by calculating the energy. This can be obtained as follow:

Mass (m) = 40 kg

Height (h) = 3 m

Acceleration due to gravity (g) = 10 m/s²

E = 40 × 10 × 3

Finally, we shall determine the power exert in climbing the stairs. This can be obtained as follow:

Energy (E) = 1200 J  

Time (t) = 6 s

[tex]Power = \frac{Energy }{Time}\\\\Power = \frac{1200}{6}[/tex]

Thus, 200 W was used in climbing the stairs.

Answer:

m = 0.1 [kg]

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.

[tex]F =m*a[/tex]

where:

F = force = 16[N]

a = acceleration = 160 [m/s²]

m = mass [kg]

Now replacing:

[tex]m=F/a\\m = 16/160\\m = 0.1 [kg][/tex]

Explanation:

The shattering of glass with the help of sound illustrates an example of resonance. Thus, the correct option for this question is C.

In physics, resonance may be defined as a type of phenomenon due to which an exterior force of a vibrating system significantly forces another system around it in order to vibrate with greater amplitude at a specified frequency of operation.

According to the context of this question, the resonance produced by the voice of Ella Fitzgerald results in the breaking or shattering of the glass. It exposes the glass to the sound wave that forces or to vibrate and distorts its shape. Physical phenomena like refraction, diffraction, and interference are related to the concept of light.

Therefore, the shattering of glass with the help of sound illustrates an example of resonance. Thus, the correct option for this question is C.

Answer:

Rock Formation

Explanation:

If Earth did not have internal energy, the carbon cycle process that would not be possible is rock formation. So, the correct option is D.

The carbon cycle is described as a series of biogeochemical processes through which atoms of carbon or carbon compounds are fixed and utilized within the environment, moving carbon from the atmosphere to the Earth and back against which is carried into the atmosphere.

The main processes associated with carbon cycle include the following:

The formation of rock requires only that the Earth have enough internal energy to cause the movement of material around the core and mantle to cause slow but significant changes within the Earth's crust.

Therefore, the correct option is D
