According to Galileo's pendulum theory, which factor determines the time taken to swing through one complete cycle?

2 answers:

6 0

It depends on the length of the string and the speed its swinging at. If its short then it will reach the full swing in less of a time but if its a longer string then it would take a longer time to make a full swing.

Explanation :

The time period of the Galileo's pendulum is given by :

$T=2\pi\sqrt{\dfrac{L}{g}}$

Where,

L is the length of the pendulum

g is acceleration due to gravity

So, the time period of the depends on the length of the pendulum. It is independent of the mass of the bob and its amplitude.

So, the length is the only factor that determines the time taken to swing through one complete cycle is the length of the pendulum.

What wave on the electromagnetic spectrum has the highest frequency?

Jet001 [13]

Answer:

Explanation:

Answer: Gamma rays

Gamma rays have the highest frequency.

What is an electromagnetic wave?

An electromagnetic wave requires no medium for its propagation.

It consists of a spectrum of different wavelengths.

Different wavelengths of rays have different energies and different frequencies.

Higher frequency rays have the highest energies.

What is gamma-ray?

These are ionized radiations.

Gamma radiations are obtained from the decay of the atomic nucleus.

It has the highest frequency which is why it can penetrate through matter.

It has the smallest wavelength and highest energy.

The frequency of gamma rays is more than 10^19 cycles per second and wavelength less than 100 picometers.

A 42.0-kg parachutist is moving straight downward with a speed of 3.85 m/s. (a) If the parachutist comes to rest with constant a

RideAnS [48]

Answer:

-414.96 N

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration

$v^2-u^2=2as\\\Rightarrow a=\frac{v^2-u^2}{2s}\\\Rightarrow a=\frac{0^2-3.85^2}{2\times 0.75}\\\Rightarrow a=-9.88\ m/s^2$

$F=ma\\\Rightarrow F=42\times -9.88\\\Rightarrow F=-414.96\ N$

The force the ground exerts on the parachutist is -414.96 N

If the distance is shorter than 0.75 m then the acceleration will increase causing the force to increase

Which scientist contributed to disproving spontaneous generation?

kompoz [17]

Answer:

A. John Tyndall

Explanation:

In 1887, John Tyndall confirmed the theory of biogenesis, formulated by Luis Pasteur in 1864, applying sterilization by discontinuous heating, a process that is currently known as tyndalization. Evidence of the existence of resting microbacterial forms, very resistant to heat.

Thanks to this demonstration he is recognized as the father of microbiology with Pasteur. The theory brought down the previous idea of the Spontaneous Generation, which remained in force since 1745.
