1. They both are same in the process, I mean they both are types of cell division they both form and give rise to new cells from the existing ones
difference would be in their division a mitotic cell gives rise to 2 cells where as a meiotic cell gives rise to 4.
2. the advantage of sexual reproduction is that , it produces genetic variation, disadvantage is it's a very slow process and takes lot of time
3. the advantage is that ,it's a very rapid process as it doesn't involve complex interactions. of genes and chromosomal recombination, the disadvantage would be is that they don't produce variation which can have adverse affect on their survival, even due to slightest change in the environment
4. Undergoing both the type of cell division is good as in human mitotic division is meant for growth and development whereas meiotic divisions are necessary and important for gametes formation and for raising new generation
When discussing discordant and harmonious sound waves, the
statement that is false is knowing the frequencies of the original waves is
useful in determining if the result will be discordant or harmonious. The
answer is letter B.
c) only from warmer areas to colder areas.
The second principle of thermodynamics states that heat can only flow from a hotter body to a cooler one. Specifically, Clausius statement says that is not possible for heat to move by itself from a lower temperature body to a higher temperature body.
Answer:
0.6 Ω
Explanation:
As shown in the diagram below,
Since the resistance and the ammeter are connected in series,
(i) The same amount of current flows through them.
(ii) The sum of their individual individual voltage is equal to the total voltage of the circuit.
Applying ohm's law,
V = IR................ Equation 1
Where V = Voltage across the ammeter, I = current flowing through the ammeter, R = resistance of the ammeter.
make R the subject of the equation
R = V/I............... Equation 2
Given: V = 1.2-0.9 = 0.3 V, I = 0.5 A.
Substitute into equation 2
R = 0.3/0.5
R = 0.6 Ω
Answer:
N₁ -N₂ = mg [(v₁²-v₂²) / rg + 2]
N₁- N₂ = 2mg
Explanation:
For this problem we apply Newton's second law at the two points
Bottom of the circle
Y Axis
N₁ - W = m a
N₁ = m (a₁ + g)
N₁ = mg (a₁ / g + 1)
Acceleration is centripetal
a₁ = v₁² / r
N₁ = mg (v₁² / rg + 1)
Top of the circle
Y Axis
-N₂ - W = m (-a₂)
N₂ = m (a₂- g)
N₂ = m g (a₂ / g - 1)
a₂ = v₂² / r
N₂ = mg (v₂² / rg -1)
The difference between this normal force is
N₁ -N₂ = mg [v₁² / rg +1 - v₂² / rg +1]
N₁ -N₂ = mg [(v₁²-v₂²) / rg + 2]
In general the speed at the top of the circle is less than the speed at the bottom, as long as you have a system to keep this speed constant, if you keep it constant the result is reduced to
N₁- N₂ = 2mg
