Answer:

TRUE                          

Explanation:

An Equipment grounding conductor are used to ground a non current-carrying metallic parts of any equipment. Its main function is to keep the equipment close to the ground potential as possible and is also allows a safer path for the ground-fault current to flow. If the equipment is grounded, all the excess current will go to the ground and will not damage the equipment.

Hence the answer is TRUE.

marissa [1.9K]

Answer:

<h2>D. Nonpolar molecules</h2>

Explanation:

The non-polar molecules are held in place by very weak van der Waals forces, hence making it to have the least melting and boiling point.

Determine the number of hydrogen atoms in an alkyne with one carbon–carbon triple bond and 4 carbon atoms.
rewona [7]

Answer:

There are 6 hydrogen atoms.

Explanation:

The formula for an alkyne that has only one triple bond is as follows:

  • CₙH₂₍ₙ₎₋₂

Where n is any natural number greater than 2.

For this problem, n=4. This would mean the formula is:

  • C₄H₂₍₄₎₋₂

Thus

  • C₄H₈₋₂
  • C₄H₆

Thus the answer is 6, there are 6 hydrogen atoms.

Why is an ecosystem still healthy although there's still a lot of consumers in it?
siniylev [52]

Answer:

because it is a sign that there are more producers for the consumers.

Explanation:

An ecosystem consist of the abiotic or inorganic components, the animals[consumers], the plants[producers] and the decomposers. An ecosystem simply means the environment of organisms that are living together and the way these organisms interact with another.

The producers that is the plants are the ones manufacturing food by themselves either by photosynthesis or chemosynthesis and the consumers are the ones relying on the producers for food.

The ecosystem is still healthy even when there's still a lot of consumers in it because it shows that there are come producers that is to say the producers are more also. If this is not the case, then the ecosystem will not be healthy as the consumers will eat the producers until the producers will not be enough.
