Explanation:

X-rays are the electromagnetic waves whose photons are of higher energy and short wavelength that ranges beyond the visible region for the human-eyes.

The visible light lies between the wavelength of 4000 A^{\circ} to 7000 A^{\circ}.

The x-ray photons are the result of highly excited electron from its ground state than the electron releasing visible light photons.

The smaller atoms, in which the electron orbitals are separated by relatively low jumps in energy, are less likely to absorb X-ray photons.

Explanation:

X-rays are almost same as the visible light as they both electromagnetic waves with same speed. However, the only difference the energy level of photons of X- rays are higher than those of the visible light. This is because the frequency of the X-rays are higher.

E= h\nu

h= plank's constant and \nu is the frequency of the wave. So, higher the  frequency higher will be the energy of the wave.

Un cubo de madera de densidad 0.780 g/cm³ mide 11.2 cm en un lado. Cuando se coloca en agua, ¿qué altura del bloque flotará sobr
Stolb23 [73]

Answer:

2.464 cm above the water surface

Explanation:

Recall that for the cube to float, means that the volume of water displaced weights the same as the weight of the block.

We calculate the weight of the block multiplying its density (0.78 gr/cm^3) times its volume (11.2^3  cm^3):

weight of the block = 0.78 * 11.2^3  gr

Now the displaced water will have a volume equal to the base of the cube (11.2 cm^2) times the part of the cube (x) that is under water. Recall as well that the density of water is 1 gr/cm^3.

So the weight of the volume of water displaced is:

weight of water = 1 * 11.2^2 * x

we make both weight expressions equal each other for the floating requirement:

0.78 * 11.2^3 = 11.2^2 * x

then x = 0.78 * 11.2 cm = 8.736 cm

This "x" is the portion of the cube under water. Then to estimate what is left of the cube above water, we subtract it from the cube's height (11.2 cm) as follows:

11.2 cm - 8.736 cm = 2.464 cm

2. Below are four velocity vs. time graphs. Which graph represents the motion of an object that
Airida [17]

Answer:

Answer (b)

Explanation:

Acceleration is the rate of change of velocity in time, therefore constant acceleration will be changing velocity in direct proportion to time and will have a linear plot on a velocity/time chart. This eliminates answer (d) which has an increasing acceleration in time

answer (a) has a negative slope so the acceleration would be considered negative

answer (c) has zero slope so acceleration is zero and velocity is constant.

answer (b) has the required positive slope and acceleration

Weight=1500n area=0.5 m2 pressure=​
Dmitriy789 [7]

Answer: 6000N/m^2

Explanation:

Weight =1500N

Area =0.5m^2

Pressure =1500/(0.5^2)

               =6000N/m^2

Note: Newton is denoted by 'N' (Capital) and use '^' for powers.
