Why Don't Birds Get Electrocuted When They Land on Electric Wires?

Chemistry

Answer:

Birds are able to sit on electrical power lines because the electrical current essentially ignores the bird's presence and continues to travel through the wire instead of through the bird's body. A bird's body is not a good conductor of electricity.

This gas law works only if temperature is recorded in ———— units

Vsevolod [243]

Answer:

Kelvin

Explanation:

Gas laws re the laws that relates properties of gases such as pressure, temperature and volume at different conditions.
Gas laws includes, Boyle's law, Charles law, grahams law and pressure law among others.
Temperature is one of the quantity of gases explained by gas laws. For gas laws to work, temperature should always be in Kelvin. Therefore, when given temperature in degrees, it is converted to Kelvin by adding 273, that is °C + 273 = K.

Which tiny, round “factory” puts together protein and is often found in the endoplasmic reticulum?

hodyreva [135]

In the cytoplasm, ribsomal RNA (rRNA), a type of RNA, and protein combine to form a nucleoprotein called a ribosome. The ribosome serves as the site and carries the enzymes necessary for protein synthesis. They are often takes the shape of small round particles attached in the endoplasmic reticulum. The ribosome attaches itself to m-RNA and provides the stabilizing structure to hold all substances in position as the protein is synthesized. Several ribosomes may be attached to a single RNA at any time.

Which statement is true according to the kinetic theory? Will mark brainliest

nevsk [136]

Answer:

$\boxed{\sf Option \ E}$

Explanation:

All the gases at the same temperature and mass have the same average kinetic energy.

If the masses were different, then the different gases will have different velocities. If the temperature was higher then there would be a greater motion, if the temperature was lower, then there would be less motion.

In the first law of thermodynamics, △E = Q-w, what does △E stand for?

Damm [24]

Answer: The correct answer is Option B.

Explanation:

First law of thermodynamics states that the energy can neither be destroyed not be formed but it can only be transformed from one form to another.

Here, the internal energy of the system is being transformed to the heat energy and the work done by the system. The equation used to represent first law of thermodynamic is:

$\Delta E=Q-w$

where,

$\Delta E$ represents the internal energy of the system.

Q = heat released or absorbed by the system.

w = work done by or on the system.

Hence, the correct answer is Option B.

What kind of feature results from the convergence of two oceanic plates?

Liono4ka [1.6K]

Answer: When a convergent boundary occurs between two oceanic plates, one of those plates will subduct beneath the other. Normally the older plate will subduct because of its higher density. The subducting plate is heated as it is forced deeper into the mantle, and at a depth of about 100 miles (150 km) the plate begins to melt.
