4. Which of the following sets of EM radiation can harm your body cells?
a. Gamma ray, microwaves, infrared
b. Light, ultraviolet, x-ray
c. Microwaves, ultraviolet, infrared
d. Ultraviolet, x-ray, gamma ray

Answers

Answer:

the correct one is D,  

Ultraviolet, x-ray, gamma ray

Explanation:

Electromagnetism radiation are waves of energy that is expressed by the Planck relationship

          E = h f

where h is the plank constant and f the frequency of the radiation.

Also the speed of light is

          c = λ f

         

we substitute

          E = h c /λ

therefore to damage the cells of the body radiation of appreciable energy is needed

microwave radiation has an energy of 10⁻⁵ eV

infrared radiation                E = 10⁻² eV

visible radiation                   E = 1 to 3 eV

radiation Uv                         E = 3 to 6 eV

X-ray                                    E = 10 eV

 

gamma rays                         E = 10 5 eV

therefore we see that the high energy radiation is gamma rays, x-rays and ultraviolet light.

When checking the answers, the correct one is D

TRUE if the statement is correct and write FALSE if is not.

The air speeds up, and as it speeds up, its pressure—the force of the air pressing against the side of the object—goes down. ...

Explanation:

Sir Isaac Newton was among the first to observe the movement of objects and express those observations as laws. According to Newton's law of inertia, a body

a. in variable motion will remain in motion unless its state of matter changes.

b. with no kinetic energy will remain along a path with a constant radius.

c. with a variable potential energy will remain with a constant, nonzero acceleration.

d. in uniform motion will remain in motion unless it is acted upon by an outside force ​

Answers

Answer:

it's D

Explanation:

Newton's first law of motion states that a body at rest remains at rest or if in motion remains in motion at a constant velocity unless acted upon by a external Force

The correct option is D. In uniform motion will remain in motion unless it is acted upon by an outside force .

What is newton s law ?

Unless influenced by an imbalanced force, an item at rest stays at rest, and an object in motion keeps moving in a straight path at a constant pace. An object's acceleration is determined by its mass and the force being applied.

Every time one object applies force to another, the other object applies an equal and opposite force to the first.

According to Newton's first law, unless pushed to alter its condition by the operation of an external force, every object will continue to be at rest or in uniform motion in a straight line. Inertia is the propensity to resist changes in a condition of motion.

Therefore, The correct option is D. In uniform motion will remain in motion unless it is acted upon by an outside force .

Can somebody please work these questions out for me?.

Answers

Answer:

Please find the calculated values entered into the following table;

[tex]\left\begin{array}{ccccc}Object & Mass \ (kg)& Weight \ (N) & Height \ (m)&G.P.E.\\A&5&50&2&100\\B&2&20&6&120\\C&8&80&5&400\\D&20&200&0.6&120\\E&5,000&50,000&2&100,000\\F&0.2&2&10&20\\G&67&670&44&29,480\end{array}[/tex]

Explanation:

The given parameters are;

The acceleration due to gravity, g ≈ 10 N/kg

The Gravitational Potential Energy, G.P.E. = m × g × h

The weight of the object, W = m × g

∴ G.P.E. = W × h

The table is filled using the above formula for calculations as follows;

For object A, we have;

Weight = 5 kg × 10 N/kg = 50 N

G.P.E. = 50 N × 2 m = 100 J

For object B, we have;

Weight = 2 kg × 10 N/kg = 20 N

G.P.E. = 20 N × 6 m = 120 J

For object C, we have;

Weight = 8 kg × 10 N/kg = 80N

G.P.E. = 80 N × 5 m = 400 J

For object D, we have;

Weight = 20 kg × 10 N/kg = 200 N

G.P.E. = 200 N × 0.6 m = 120 J

For object E, we have;

Weight = 5,000 kg × 10 N/kg = 50,000 N

G.P.E. = 50,000N × 2 m = 100,000 J

For object F, we have;

Weight = 0.2 kg × 10 N/kg = 2 N

G.P.E. = 2 N × 10 m = 20 J

For object G, we have;

Weight = 67 kg × 10 N/kg = 670 N

G.P.E. = 670 N × 44 m = 29,480 J

Therefore, we have the table filled as follows;

[tex]\left\begin{array}{ccccc}Object & Mass \ (kg)& Weight \ (N) & Height \ (m)&G.P.E.\\A&5&50&2&100\\B&2&20&6&120\\C&8&80&5&400\\D&20&200&0.6&120\\E&5,000&50,000&2&100,000\\F&0.2&2&10&20\\G&67&670&44&29,480\end{array}[/tex]

C.

D.

Most metals can be drawn into a wire, while nonmetals would break apart.

Answers

Answer:

D.   Most metals can be drawn into a wire, while nonmetals would break apart

Explanation:

The correct statement from the given choices is that most metals can be drawn into a wire while non-metals would break apart.

Metals are malleable due to the presence of metallic bonds between their atoms. The large electron cloud due to the electropositivity of metals allows for the wide range of physical properties observed in them.

Metals are also conductors because they have free mobile electrons. Therefore they can conduct heat and electricity.

Non-metals are brittle and cannot conduct neither heat nor electricity.
