How many components do vectors have, and what are they?

Physics
1 answer:
zepelin [54]3 years ago
8 0

Answer:

There are two components for a two-dimensional coordinate system/vector.

Explanation:

For two-dimensional vectors, such as velocity, acceleraton, etc, there are two components, the x- and y-components.

These components could be rotated or translated, depending on the coordinate system.

Instead of rectangular cartesian system, the components could also be in the form of polar coordinates, such as radius and theta (angle).

For three-dimensional vectors, such as velocity in space, there are three components, in various coordinate systems.

Rebecca heated 50mL of water from 0 degrees Celsius to 60 degrees Celsius. How much energy did she use to heat the water? Rememb
kramer

Answer:

12552 J or 3000 calories

Explanation:

Q = m × c × ∆T

Where;

Q = amount of heat energy (J)

m = mass of water (g)

c = specific heat capacity (4.184 J/g°C)

∆T = change in temperature

For 50mL of water, there are 50g, hence, m = 50g, c = 4.184 J/g°C, initial temperature = 0°C, final temperature = 60°C.

Q = m × c × ∆T

Q = 50 × 4.184 × (60 - 0)

Q = 209.2 × 60

Q = 12552 J

Hence, the amount of heat energy used to heat the water is 12552 J or 3000 calories

Do you believe that global warming is happening? Tell why or why not. If you believe global warming is happening, what can we do
adoni [48]

Answer:

Yes I do believe global warming is happening, mainly because there is a plethora of data and research from scientists to support the claim. The effects of global warming around us are clearly observed as well, such as the rise in acidity in the oceans. Another example is in the Artic, where a natural occurence takes place. Ice freezes and cold salty water takes its place, and because of it's high density it sinks and sweeps across the ocean floor. That cold water is then replaced by warmer water, and this is called the global ocean conveyor belt. As seen through the example with the Artic, ocean temperature plays a key role in the conveyor belt. Climate change is fueled through human activities, which could harm the system. If one part of the conveyor belt were to break down, such as the one in the Artic,  nutrients will not be distributed to start the food chain. Organisms such as phytoplankton need those nutrients to thrive. If phytoplankton are endangered, all life in the oceans is endangered. So as we can see, global warming is extremely harmful to the environment and it's effects are observed around us.

To slow global warming down we should consume less meat, and go to vegan or vegetarian diets. Your carbon footprint is halved by consuming less meat and eating a more vegan or vegetarian diet. Another thing is that we as a society should stop using so much plastic. It takes more than a century to degrade, most landfills are composed of it. Microplastics also get into our oceans, and our fish end up consuming them.
