How much does 1 liter of water weigh

P waves and S waves are alike in that they __________.

sammy [17]

<h3>Answer;</h3>

travel through solids

P waves and S waves are alike in that they both travel through solids.

<h3>Explanation;</h3>

P-waves and S-waves are types of seismic waves. These waves are produced during an earthquake, that transmit energy released around the earth.
P-waves travel the fastest and also travel through solids, liquids and gases. They are push and pull waves and thus they cause rock particles to move back and forth.
S-wave son the other hand arrive at a given point after the p-waves. They do not travel as fast as P-waves. They travel through solids but not in liquids and gases. S -waves cause the rocks to move side to side.

A laser beam of wavelength 600 nm is incident on two slits that are separated by 0.02 mm. What is the separation between adjacen

Liula [17]

Answer:

option D

Explanation:

given,

wavelength = 600 nm

width of separation = 0.02 mm

L = 5 m

for mth order maxima

$d \times \dfrac{y_m}{L}=m\lambda$

for (m+1)th order maxima

$d \times \dfrac{y_{m+1}}{L}=(m+1)\lambda$

now,

$y_m=\dfrac{mL\lambda}{d}$ and

$y_{m+1}=\dfrac{(m+1)L\lambda}{d}$

hence,

$\Delta y = y_{m+1} - y_m$

$\Delta y =\dfrac{L\lambda}{d}$

$\Delta y =\dfrac{5 \times 600 \times 10^{-9}}{0.02 \times 10^{-3}}$

$\Delta y =0.15\ m$

$\Delta y =15\ cm$

hence, the correct answer is option D

A light-emitting diode (LED) connected to a 3.0 V power supply emits 440 nm blue light. The current in the LED is 11 mA , and th

zimovet [89]

Answer:

3.73 * 10^16 photons/sec

Explanation:

power supply = 3.0 V

Emits 440 nm blue light

current in LED = 11 mA

efficiency of LED = 51%

Calculate the number of photons per second the LED will emit

first step : calculate the energy of the Photon

E = hc / λ

=( 6.62 * 10^-34 * 3 * 10^8 ) / 440 * 10^-9

= 0.0451 * 10^-17 J

= ( 3 * 0.51 * 11 * 10^-3 ) / 0.0451 * 10^-17

= 3.73 * 10^16 photons/sec

Bird bones have air pockets in them to reduce their weight–this also gives them an average density significantly less than that

lakkis [162]

Answer:

a)39ml

b)39g

c)1.1g/ml

Explanation:

Hello!

To solve this exercise use the following steps

1. When Archimedes discovered how to determine the irregular volume of an object by weighing it in the air and in an algua, he found that its volume is equal to the ratio between the differences of the masses (heavy in the air and in the water) and the density of the water (= 1g / ml)

$V=\frac{43g-3.6g}{1g/ml} =39.4ml$

2.as the principle of archimedes says, the displaced volume of water is equal to the volume of the bone which means that 39.4ml of water was displaced, taking into account that the density of water is the ratio between mass and volume we can determine the displaced body of water

$density=\frac{m}{V} \\m=V(density)\\m=(39ml)(1g/ml)=39g$

3. we use the density equation to find the bone density

$density=\frac{43g}{39ml} =1.1g/ml$

A 102 kg box is pushed on a linoleum floor with an acceleration of 2.5 ms to the second power. The force of the kinetic movie fr

maria [59]

A force is the push or pull acting on an object as a result of its interaction with another object. Here the net force acting on the box is 297 N

From the question

Given that,

Mass of the box ,m = 102 kg

Acceleration of the box ,a = 2.5 m/s²

Frictional force acting between the box and the floor ,f = 42 N

Here we have to find the net force acting on the body, F = ?

By Newton's second law of motion,

∑F = ma,

where, F is the net force

m is the mass of the body

a is the acceleration of the moving body

If the body is considered moving in the x-direction then,

F-f = ma

F - 42 = 102 x 2.5

= 255

F = 255 + 42 = 297 N
