Answer:
A cell cycle is a series of events that takes place in a cell as it grows and divides. The cell then leaves interphase, undergoes mitosis, and completes its division. The resulting cells, known as daughter cells, each enter their own interphase and begin a new round of the cell cycle.
There is zero net force required to keep an object moving, even in the same direction. This is because the inertia only depends on the mass of the object moving, not the speed. Therefore, the answer would be none.
Answer : Option A) Increase
Explanation : When a bigger battery is installed there is an increase in amount of current observed.
As per Ohm's law;
Voltage = Current X Resistance.
So, when a bigger battery is installed more number of electrons will flow across the circuit producing more current than before.
Answer:
Time period between the successive beats will be 0.1703 sec
Explanation:
We have given speed of the sound v = 349 m/sec
Wavelength of piano 
Wavelength of piano 
So frequency of piano A 
Frequency of piano B 
So beat frequency f = 455.61 - 449.74 = 5.87 Hz
So time period 
So time period between the successive beats will be 0.1703 sec
