The acceleration of an object is measure by its change in velocity per unit time. The equation for acceleration is: a =v/t. Acceleration is represented by 'a'. Velocity is represented by 'v'. Time is represented by 't'. Rearrange the equation to solve for time.

Answers

Answer:

t=v/a

Explanation:

To solve for Time

Since acceleration is change in velocity/time

a=v/t

Cross multiply

a×t=v

at=v

Divide both side by a since we want to find Time

at/a=v/a

t= v/a

How are predation, parasitism, and herbivory similar?

Herbivory, parasitism, and predation have one thing in common: they all cause harm to the other creature while giving the other organism advantages. The difference between them is that predators capture and eat their prey, but parasites lodge inside their hosts and dwell there, while in herbivores, adaptations are made to help the prey survive.

The difference between them is that predators capture and eat their prey, but parasites lodge inside their hosts and dwell there, while in herbivores, adaptations are made to help the prey survive.

In terms of the signs of the interaction coefficients between the two populations, parasitism and predation are similar, but parasitism differs from predation in that members of the affected species suffer harm.

The idea of laissez-faire, or how much the government should do, is

DONE

Answers

Answer:

Laissez-faire means that the government does not interfere with people's right to pursue happiness.

The idea of laissez-faire, or how much the government should do, is debated heavily.

Explanation:

Laissez-faire is the main concept defended by economic liberalism and capitalism, mainly in the USA and other countries that adopt this type of concept. In a simple way, Laissez-faire can be defined as the separation of the State and the commerce of a region. This means, that in places where Laissez-faire is adopted, the State, ie the government, does not have the right to interfere in any type of commercial relationship and should only be responsible for guaranteeing property rights and consumer protection, otherwise, trade must regulate itself, within its own limits.

While many people see this policy as beneficial, preventing government from interfering with people's happiness, others believe that Laissez-faire is not beneficial and that government interference, or lack of it, should be discussed.

Water is a chemical compound and polar molecule, which is liquid at standard temperature and pressure. It has the chemical formula H2O, meaning that one molecule of water is composed of two hydrogen atoms and one oxygen atom. Water is found almost everywhere on earth and is required by all known life. About 70% of the Earth's surface is covered by water. Water is known to exist, in ice form, on several other bodies in the solar system and beyond, and proof that it exists (or did exist) in liquid form anywhere besides Earth would be strong evidence of extraterrestrial life.
