Cell membrane can also be called plasma membrane
By definition, we have to:
Calcium Bromide is an inorganic salt formed by granular white crystals that responds to the formula CaBr2.
Calcium bromide has no odor, is colorless and has a bitter taste.
It is obtained by adding Hydrobromic Acid to Calcium Oxide, Calcium Carbonate or Calcium Hydroxide.
The substance that results is then subjected to a crystallization process, which involves evaporating the water.
From here, you get then:
CaBr2.
Answer:
CaBr2 = Calcium bromide.
Answer: 9.8N
Explanation: The velocity of a sound wave (v), tension on the string (T) and mass per unit length (u) are all related by the formulae below
T = v² * u
Where T is tension in Newton (N), v is velocity of sound waves in meter per seconds (m/s) and u is mass per unit length in kilogram per meter (kg/m)
u = mass of chord / length of chord
u = 0.44/ 8.1
u = 0.1 kg/m
Velocity of sound waves (v) =length of chord / time taken for wave to travel
v = 8.1 / 0.82 = 9.9m/s
Tension is calculated below using the formula
T = v² * u
T = (9.9)² x 0.1
T= 9.8N
- According to Newton's Third Law of Motion, to every action, there is an equal and opposite reaction; action and reaction act on different bodies.
- Here, the action force is in the leftward direction, so the reaction will be in the opposite direction.
- If the action force is the swimmer pushing water in the leftward direction, then the reaction force is in the rightward direction.
- And the reaction force will be given by the water on the swimmer.
<u>Answer</u><u>:</u>
<u>The </u><u>reaction </u><u>force </u><u>is </u><u>the </u><u>water </u><u>pushing </u><u>the </u><u>swimmer </u><u>in </u><u>the </u><u>rightward </u><u>direction</u><u>.</u>
Hope you could get an idea from here.

Answer:
89.5 Hz
Explanation:
The relationship between the frequency and the wavelength is given by the following formula:
where,
f = frequency
c = speed of light
λ = wavelength
Since the speed of light is constant. Therefore the formula suggests an inverse relationship between the frequency and the wavelength. Hence, the station with the lowest frequency will have the longest wavelength.
Therefore, the answer is:
<u>89.5 Hz</u>
