Answer:

hello . proton:17 electron:18 neutron :18

Explanation:

it's obvious and you must memorise that Cl has 17 protons .

because it has one negative so electrons which are negative should be one more than protons I mean 18

neutron doesn't need to look at it here

electron shows the answer.

hope u understand

if u have any questions don't hesitate to ask.

It takes 0.26 minutes to travel 1000 feet

Solution:

Given that car traveling at a constant speed travels 175 miles in four hours

Distance = 175 miles

Time taken = 4 hours

Convert the units to feet and minute

Given that,

1 mile = 5280 feet

175 miles = 5280 x 175 feet = 918720 feet

Also we know that,

1 hour = 60 minutes

4 hours = 60 x 4 minutes = 240 minutes

Thus, we got,

Distance = 918720 feet

Time taken = 240 minutes

Find the speed of car

Speed is given by formula:

$speed = \frac{distance}{time}$

$speed = \frac{918720}{240} = 3828$

Thus speed of car is 3828 feet per minute

How many minutes will it take for the car to travel 1000 feet?

Let "x" be the minutes needed for 1000 feet

speed of car is 3828 feet per minute

1 minute = 3828 feet

x minute = 1000 feet

This forms a proportion. We can solve by cross multiplying

$x \times 3828 = 1000 \times 1\\\\x = \frac{1000}{3828}\\\\x = 0.26$

Thus it takes 0.26 minutes to travel 1000 feet

when obtaining energy, why mushrooms are more like elephants eating and not like dandelions absorbing sunlight.

Julli [10]

Answer:

Because they lack chlorophyll (a green pigment in plants that helps them trap sunlight, used to manufacture their food through photosynthesis)

Explanation:

Mushrooms are heterotrophs. They are not plants or autotrophs. Mushrooms, just like every living thing that exists need energy in order to live. Only plants, or autotrophs, can directly use energy from the sun (the ultimate energy) to make food. Those organisms that cannot harness the sun's energy are known as heterotrophs. Mushrooms are fungi (belong to kingdom Fungi) and are heterotrophs because they decompose and consume nutrients from the soil. They are not green so they cannot photosynthesis due to lack of chlorophyll.
