 Why are radio waves safer to humans than X- Rays

Physics
1 answer:
julsineya [31]3 years ago
3 0

Answer:

Explanation:

Since X-rays are high (energy) frequency photons and radio waves are composed of low (energy) frequency photons, X-rays are more energetic and can do more harm to organic materials (such as cells).

According to Newton's Law of Cooling, if a body with temperature T 1 is placed in surroundings with temperature T 0, different f
Mila [183]

We can substitute the given values into the equation for T, given the surrounding temperature T0 = 0, initial temperature T1 = 140, constant k = -0.0815, and time t = 15 minutes.

T = 0 + (140 - 0)e^(-0.0815*15) = 140e^(-1.2225) = 41.23°F

The density of 2 kilograms of iron on Earth's surface is
Eduardwww [97]

Answer:

B. The same on the moon.

Explanation:

The density of an object is the ratio of the mass contained by the object to the volume occupied by that mass.

Density = \frac{Mass}{Volume}

When the object is taken from the earth to anywhere in the universe, its mass remains constant. The dimensions of the object and hence its volume also remains constant anywhere in the universe.

Therefore, the density of the object will also remain the same as it depends upon the mass and the volume of the object.

So, the correct option is:

<u>B. The same on the moon.</u>

If an otherwise empty pressure cooker is filled with air of room temperature and then placed on a hot stove, what would be the m
Margaret [11]

Ideal Gas Law is, pV = NkbT

<span>Therefore, p/t  = Nkb/V which is equal to the constant</span>

We need to convert the given temperature to Kelvin. We need to add 273 to have the Kelvin of the temperature from Celsius.

T1= 20 + 273 = 293 K

T2= 120 + 273 = 393 K

With this we have the pressure ration of 393/293.

So,F120 = 1.34 APa

Zolol [24]
(sorry I can only answer no. 1)
