What is the area of a car that touches the road if the car’s weight on that tire is 288 N and the pressure exerted on the road is 36 Pa?
Answers
Answer:
Car's touch area = 64 m²
Explanation:
Given:
Weight of car = 3,072 N
Pressure = 48 pa
Find:
Car's touch area
Computation:
Area = Force / Pressure
Car's touch area = 3,072 / 48
Car's touch area = 64 m²
Answer:64m2
Explanation:
As we know pressure is equal to force divided by unit area so if we rearrange the equation and isolate area we get area is equal to force divided by pressure exerted. By putting values we get 64m2.

group 3–12
group 1
group 17
group 2
Answers
Answer:
group 3–12used for manufacturing paints and plastic
group 1 stored under oil they are very reactive
group 17used as a disinfectant
group 2 used to reduce stomach acid
Explanation:
The elements that are used as disinfectant comes under the group of halogens. So, group 17.
What is meant by the group in a periodic table ?The group is defined as a column in the periodic table, that contains the elements having the same number of valence electrons.
Here,
1) Element is used as a disinfectant.
The elements that are used as disinfectant comes under the group of halogens. So, group 17.
2) Element important for the proper functioning of the human body.
The compounds of group 2 elements are used for the neutralization of the acids in stomach.
3) Element always stored under oil.
To avoid the oxidation of the elements, the group 2 elements are always stored in oil.
4) Compounds of this element are used in manufacturing of paints.
The elements like Zin, Cobalt, Bromine, etc. are used to make paints. So, group 3 - 12.
Hence,
The elements that are used as disinfectant comes under the group of halogens. So, group 17.
