S=Vt
110=V(72)
110/72=V
V=1.527m/s
Answer:Thermal energy is a measure of a substance 's specific heat
Explanation:
Answer:
The angle of separation is
Explanation:
From the question we are told that
The angle of incidence is 
The refractive index of violet light in diamond is 
The refractive index of red light in diamond is 
The wavelength of violet light is
The wavelength of red light is
Snell's Law can be represented mathematically as

Where
is the angle of refraction
=> 
Now considering violet light

substituting values




Now considering red light

substituting values




The angle of separation between the red light and the violet light is mathematically evaluated as

substituting values


Answer:
The correct statements would be
- Cyanobacteria allowed organisms that rely on oxygen to evolve.
- Cyanobacteria preceded the first photosynthetic organisms.
- Cyanobacteria produced excess oxygen.
Cyanobacteria, also termed as blue-green algae are the prokaryotes which are able to perform photosynthesis.
They were the major contributors of oxygen in the atmosphere and thus helped the organisms that rely on oxygen to evolve.
By the process of endosymbiosis, they lead to the origin of plants. The chloroplasts present in green plants is considered as the cyanobacteria living in the plant cell. It helps in photosynthesis and in return plants cell provides shelter to it.
It is believed that the oxygen released from early cyanobacteria reacted with dissolved iron ions to form iron oxide.
Answer:
Explanation:
solve the parallel resistances
30||40 and 50||30
17.14285714 and 18.75
total Resistance = 35.89285714
V = IR
9V = I *35.89285714
9V / 35.89285714 = I
0.250746 = I
Now use the resistance across AB
V = 17.14285714 * 0.250746
V = 4.29850
this is the Voltage drop across AB :P
