Electromagnetic waves are transverse waves. They consist of traveling electric and magnetic fields which oscillate periodically.

What angle does the electric field make with the magnetic field in an electromagnetic wave?

The angle made by electric field with the magnetic field in an electromagnetic wave is 90° or right angle.

<u>Explanation:</u>

The electrical & magnetic fields are at the 90 degree i.e at the right angles to the way the wave travels. The electric field oscillates back and forth in one plane while the magnetic field oscillates back and forth in a perpendicular plane;

the vibration, a transverse vibration, moves in a similar direction of each of the oscillating fields. All electromagnetic waves are created by accelerated charges, and the electromagnetic force follows the inverse-square law; the magnitude of the force declines as one above the squared source distance.

Why is Newton's first law of motion important to science?
Lyrx [107]

Answer:

Newton's laws are very important because they tie into almost everything we see in everyday life. These laws tell us exactly how things move or sit still, like why you don't float out of bed or fall through the floor of your house.

Explanation: Newton's laws of motion are important because they are the foundation of classical mechanics, one of the main branches of physics. Mechanics is the study of how objects move or do not move when forces act upon them.

Consider the following reaction: NO( g) + SO 3( g) ⇌ NO 2( g) + SO 2( g) A reaction mixture initially contains 0.86 atm NO and 0
DIA [1.3K]

Answer:

The equilibrium pressure of NO2 is 0.084 atm

Explanation:

Step 1: Data given

A reaction mixture initially contains 0.86 atm NO and 0.86 atm SO3.

Kp = 0.0118

Step 2: The balanced equation

NO( g) + SO3( g) ⇌ NO2( g) + SO2( g)

Step 3: The initial pressures

p(NO) = 0.86 atm

p(SO3) = 0.86 atm

p(NO2) = 0 atm

p(SO2) = 0 atm

Step 4: The pressure at the equilibrium

For 1 mol NO we need 1 mol SO3 to produce 1 mol NO2 and 1 mol SO2

p(NO) = 0.86 -x atm

p(SO3) = 0.86 -xatm

p(NO2) = x atm

p(SO2) = x atm

Step 5: Define Kp

Kp = ((pNO2)*(pSO2)) / ((pNO)*(pSO3))

Kp = 0.0118 = x²/(0.86 - x)²

X = 0.08427

p(NO) = 0.86 -0.08427 = 0.77573 atm

p(SO3) = 0.86 -0.08427 = 0.77573 atm

p(NO2) = 0.08427 atm

p(SO2) = 0.08427 atm

The equilibrium pressure of NO2 is 0.08427 atm ≈ 0.084 atm

what is the half life isotope if after 21 days you have 31.25 g remaining from a 250.0 g starting sample size?
alexgriva [62]

250 --> 125 --> 62.5 --> 31.25


each arrow equals one half life, so 3 half lives


14 days/ 3 half lives =


4.67 days = half life
