Answer:

t = 1.52 s

Explanation:

The speed of sound is constant and depends only on the properties of the medium in which the sound propagates, many of these properties change with temperature, in the case of propagation in air, the speed of sound

          v =331 \ \sqrt{1+ \frac{T}{273} }

where the temperature is in degrees centigrade

         v = 331 \sqrt{1+ \frac{6}{273} } = 331    1.0109

         v = 334.6 m / s

let's use the uniform motion relationships

         v = x / t

          t = v / x

let's calculate

          t = 334.6 / 220.0

          t = 1.52 s

Perpetual motion machines have fascinated people especially inventors for hundreds of years before the laws of thermodynamics be
Cerrena [4.2K]

Given the fact that energy conversion is not entirely efficient, it is impossible to produce a perpetual motion machine.

<h3>What is a perpetual motion machine?</h3>

The perpetual motion machine in one that is able to work continuously without stopping. This would mean that the efficiency of this machine must that the machine is 100% efficient which violates the second law of thermodynamics.

Thus, given the fact that energy conversion is not entirely efficient and energy looses cause machines not function effectively, it is impossible to produce a perpetual motion machine.

Carla draws two circuit diagrams that connect the same components in different ways, as shown. which statement about the circuit
vagabundo [1.1K]

Carla draws two circuit diagrams that connect the same components in different ways, as shown. The correct statement is "the total resistance in circuit a is greater than that in-circuit b.". Option A. This is further explained below.

<h3>What is a circuit?</h3>

Generally, a circuit is simply defined as a fixed schedule of activities or places for a certain activity, usually including athletics or public performance.

In conclusion, Carla creates two circuit schematics, as illustrated, that link the same components in various ways. "The overall resistance in circuit an is larger than that in b," is the correct statement.

No if radiactive plutonium is burnt in the air it produces plutonium oxide.do we expect the oxide to be radiactive
DerKrebs [107]

Answer:

A naturally radioactive element of the actinide metals series. Plutonium is used as a nuclear fuel, to produce radioisotopes for research, Plutonium dioxide is formed when plutonium or its compounds (except the phosphates) are ignited in air, and  Plutonium oxide fired at temperatures 600 C is difficult to rapidly.
