The uses of fossil fuel causes:

All of the above

Fossil fuels burn and increases in global temperature because it emits greenhouse gases. And the extreme climate change decreases biodiversity and last but not the least it increases pollution because burning of fuels emit gases like Carbon-dioxide etc...~

Can you please help me? It’s a science question and I really don’t know the answer

Answer:

A. It will continue traveling at the same speed.

Explanation:

I'm not 100% sure on this answer, but if I had this question I would be confident in this answer. It makes sense because unbalanced forces cause an object to start, stop, slow down, or speed up. Without these forces, the object should just keep traveling at the same speed.

I hope this helps! Let me know if it's right or not. ☺

A cell membrane is 0,0000005 m thick and has an electric potential difference between its surfaces of 0,10 V. What is the electr

Irina-Kira [14]

Answer:

Electric field in the membrane is given as

$E = 2 \times 10^5 V/m$

Explanation:

As we know that electric field in a region is related to its potential difference given by the formula

$E = \frac{\Delta V}{\Delta x}$

here we know that

$\Delta V = 0.10 V$

$\Delta x = 0.0000005 m$

so we have

$E = \frac{0.10}{0.0000005}$

$E = 2 \times 10^5 V/m$

You are making raised beds for a productive vegetable garden and have 4 boxes that are 1m x 2m x 1m deep. What volume of dirt (i

Nady [450]

Answer:

8 m³

282.3 ft³

Explanation:

The volume of each box is width times length times depth:

V = (1 m) (2 m) (1 m)

V = 2 m³

There are four boxes, so the total volume is:

4V = 8 m³

Converting to cubic feet:

8 m³ × (3.28 ft / m)³

= 282.3 ft³
