How does the way that matter cycles through an ecosystem differ from the way that energy flows?
guapka [62]

Unlike the one-way flow of energy, matter is recycled within and between ecosystems. Every living organism needs nutrients to build tissues and carry out essential life functions.

A bicyclist traveling at 5 m/s hits a fence, the bicyclist files over the fence. Which
Margarita [4]

The Newton's Laws that BEST describe the situation is Newton's second law of motion.

<h3>What is Newton's second law of motion?</h3>

Newton's second law of motion states, the force exerted by an object is directly proportional to the product of mass and acceleration of the object.

Also, the law can also be states as force is equal to the rate of change of momentum.

F ∝ Δp

Ft = m(v2 - v1)

The force exerted on the bicyclist by the fence is equal to the change in momentum of the bicyclist. The bicyclist was able to fly over the fence because there is a change in his momentum.

Thus, the Newton's Laws that BEST describe the situation is Newton's second law of motion.

In a circuit of 2 lamps in parallel if the current in one lamp is 2a the current in the other lamp is?
ioda

In a circuit having 2 lamps are connected in parallel to a battery

then the two lamps will be having the same potential as the battery

i.e

V_{1} = V_{2} = V_{battery}

As per Ohm's law,

I_{1} = \frac{V_{1}}{R_{1}} and I_{2} = \frac{V}{R_{2} }

In other words, each lamp's current is inversely related to its individual resistance. We only know the current in one of the bulbs in this specific instance. We would therefore need further information in order to calculate the current in the other light. Therefore, there isn't enough data to make a statement.

Under the assumption that all physical parameters, including temperature, remain constant, Ohm's law asserts that "the voltage across a conductor is directly proportional to the current flowing through it".

Which scientist contributed to disproving spontaneous generation?
kompoz [17]

Answer:

A. John Tyndall

Explanation:

In 1887, John Tyndall confirmed the theory of <u>biogenesis</u>, formulated by Luis Pasteur in 1864, applying sterilization by <u>discontinuous heating</u>, 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 <em>father of microbiology</em> with Pasteur. The theory brought down the previous idea of ​​the Spontaneous Generation, which remained in force since 1745.
