Which of the following best describes a transverse wave? a- displacement of particles is parallel to the direction of wave motion b- displacement of particles is perpendicular to the direction of wave motion c- displacement of particles is opposite to the direction of wave motion d- displacement of particles is in the same the direction of wave motion

The statement which best describes a transverse wave is: B- displacement of particles is perpendicular to the direction of wave motion.

A wave refers to a disturbance in a medium that progressively transports energy from a source location to another location without the transportation of matter.

Basically, there are two (2) main categories of wave and these are:

A transverse wave can be defined as a type of wave in which particles of the medium of propagation oscillates or vibrates in a direction that is perpendicular to the direction of wave motion i.e at right angle to the direction of propagation of the wave.

A good example of a transverse wave is sound wave.

In conclusion, the displacement of particles is perpendicular to the direction of wave motion for a transverse wave.

Displacement of particles is perpendicular to the direction of wave motion

Explanation:

Transverse wave is a type of wave in which the displacement of particles is perpendicular to the direction of wave motion. Other type of wave is longitudinal in which displacement of particles is parallel to the direction of wave motion.

One of the characteristics of transverse wave is that it travels in the form of crest and trough. Crest is the part where the displacement of particle is maximum while trough is the part where the displacement is minimum.

Therefore, the correct option is (b).

  the grams     of oxygen gas   that can be produced     is 20.6   grams of o₂

calculation

2liclo₃ →   2 licl + 3 o₂

step 1:   find the moles of liclo₃

moles = mass÷ molar mass

from periodic table the molar mass of liclo₃ =6.9 +35.5   +(16 x3) =90.4 g/mol

moles=38.7 g÷90.4 g/mol=0.4281   moles

step 2:   use the   mole ratio   to calculate the moles of o2

from equation above, liclo₃: o₂   is 2: 3  

therefore the moles of   o₂=0.4281 moles x3/2 =0.6422   moles

step 3: find mass   of o₂

mass= moles x molar mass

from periodic table the   molar mass of   o₂ = 16 x2= 32 g/mol

mass=0.6422   moles   x   32 g/mol = 20.6 grams of o₂

answer is slate

hope this
