Convert an absolute pressure of 6.31 ✕ 105 N/m2 to gauge pressure in lb/in2

Answers

Answer:

The gauge pressure is = 91.52 lb/in²

Explanation:

Given data,

The value of pressure in S.I unit, = 6.31 x 10⁵ N/m²

The conversion formula for SI unit into US Customary Units is given by,

1 N/m² = 1.45 x 10⁻⁴ lb/in²

Using the conversion formula, the new value of pressure becomes,

Pressure = 6.31 x 10⁵ X 1.45 x 10⁻⁴ lb/in²

= 91.52 lb/in²

Hence, the gauge pressure is, ς = 91.52 lb/in²

Why does water fill the bottom of a glass rather than cling to the side

Answers

When you pour water into a glass, gravity is pulling the water down to the bottom of the glass instead of pulling it to the sides and since glass is a substance that glass easily rolls off of, it is easier for the water molecules to locate at the bottom.

True or false? Pluto is less than 2/3 the size of Earth's moon?

Answers

Pluto has 66% of the diameter of the Earth's moon and 18% of its mass.

So your answer is true

Hope I Helped You!!! :-)

Have A Wonderful Day!!! :-)

This is a math problem. To solve this we create a ratio of the radius of Pluto to the Moon.

$(737)/(1079)$ showing that Pluto is about 68% the size of the moon. You asked if Pluto was less than $(2)/(3)$ or 66%, or less the size of the moon.

68>66 so the answer is False if you are talking about the volume or size of the two.

If you are talking about density, the ratio would be:

$(1.88)/(3.34)$ which equals 56% so the answer would be True if you are inquiring about density.

A biker accelerates from Om/s to 8m/s ub 3 seconds. What is his acceleration? Isthis acceleration higher than that of a car wihich accelerates from 0 to 30m/s in
8 seconds

Answers

Answer:

The acceleration of the biker is 2.67m/s² while that of the car is 3.75m/s². So, the acceleration of the biker is NOT HIGHER than that of the car.

Explanation:

Given that,

acceleration of biker A= ?

Initial velocity of biker Vi = Om/s

Final velocity of biker Vf = 8m/s

Time taken (t) = 3 seconds

Since acceleration is the rate of change of velocity per unit time

i.e Acceleration = (Vf - Vi) / t

A = (8m/s - 0m/s) / 3s

A = 2.67 m/s²

To know which is higher, calculate the acceleration of the car

acceleration of car A= ?

Initial velocity of car Vi = Om/s

Final velocity of car Vf = 30m/s

Time taken (t) = 8 seconds

Acceleration = (30m/s - 0m/s) / 8s

A = 30m/s / 8s

A = 3.75 m/s²

Since, the acceleration of the biker is 2.67m/s² while that of the car is 3.75m/s², the acceleration of the biker is NOT HIGHER than that of the car.

If we say that one quantity is directly proportional to another quantity, does this mean that they are equal to each other?

Answers

If we say that one quantity is directlyproportional to another quantity, we do not mean they are equal to each other.

DIRECT PROPORTION:

The term "direct proportion" refers to the relationship between two variables in which a change in one causes a similar change in the other.

This means that when two quantities are directly proportional to one another, one quantity increases as the other increases and vice versa.

For example, if quantity A is directlyproportional to quantity B;

when quantity A increases, quantity B also increases
when quantity A decreases, quantity B also decreases.

Therefore, If we say that one quantity is directly proportional to another quantity, we do not mean they are equal to each other.

NO !

It means that (one of them) divided by (the other one) is always the same number.

(Other people probably won't explain it to you this way, but I'm special, and this is true.

Anyway, the direct answer to your question is: No.)
