5 0

Answer:

b. The entropy of a pure, perfect crystalline substance at absolute zero is zero.

Explanation:

There are three laws of thermodynamics which are used to define the physical quantities and parameters like the energy, entropy, temperature. These parameters are used to characterize thermodynamic systems which are at thermal equilibrium.

The third law of thermodynamics:-

According to third law of thermodynamics, the  entropy of the system at absolute zero temperature is a very well-defined constant. Also, for the entropy of the perfect crystalline solid which is at absolute zero is equal to zero exactly.

Thus, the correct option is:- b. The entropy of a pure, perfect crystalline substance at absolute zero is zero.

Why can biofuels be described as renewable resources?​
gulaghasi [49]

Answer:

Biofuel is fuel that is produced through contemporary processes from biomass, rather than by the very slow geological processes involved in the formation of fossil fuels, such as oil. Since biomass technically can be used as a fuel directly, some people use the terms biomass and biofuel interchangeably. 

Biofuel, any fuel that is derived from biomass—that is, plant or algae material or animal waste. Since such feedstock material can be replenished readily, biofuel is considered to be a source of renewable energy, unlike fossil fuels such as petroleum, coal, and natural gas.

A small rubber ball is launched by a compressed-air cannon from ground level with an initial speed of 17.3 m/s directly upward.
elena-s [515]

Answer:

h=15.27m

Explanation:

Since at maximum height the vertical velocity must be null it's better to use the formula:

v_f^2=v_i^2+2ad

We will use this formula for the vertical direction, choosing the upward direction as the positive one, so we have:

0=v_i^2+2ah

or

h=-\frac{v_i^2}{2a}

which for our values is:

h=-\frac{(17.3m/s)^2}{2(-9.8m/s^2)}=15.27m
