If the point of the nail can be approximated as a circle with a radius 2.00×10^-3m What is the pressure in MPa exerted on the wall if a hammer strikes the nail with a force of 104 N
Answers
Answer:
8.28 MPa
Explanation:
From the question given above, the following data were obtained:
Radius (r) = 2×10¯³ m
Force applied (F) = 104 N
Pressure (P) =?
Next, we shall determine the area of the nail (i.e circle). This can be obtained as follow:
Radius (r) = 2×10¯³ m
Area (A) of circle =?
Pi (π) = 3.14
A = πr²
A = 3.14 × (2×10¯³)²
A = 3.14 × 4×10¯⁶
A = 1.256×10¯⁵ m²
Next, we shall determine the pressure. This can be obtained as follow:
Force applied (F) = 104 N
Area (A) = 1.256×10¯⁵ m²
Pressure (P) =?
P = F / A
P = 104 / 1.256×10¯⁵
P = 8280254.78 Nm¯²
Finally, we shall convert 8280254.78 Nm¯² to MPa. This can be obtained as follow:
1 Nm¯² = 1×10¯⁶ MPa
Therefore,
8280254.78 Nm¯² = 8280254.78 Nm¯² × 1×10¯⁶ MPa / 1 Nm¯²
8280254.78 Nm¯² = 8.28 MPa
Thus, the pressure exerted on the wall is 8.28 MPa
How does gravity help to demonstrate a cause-and-effect relationship?
Answers
Answer:
Gravity helps show a cause and effect by demostarting how one object will have an effect on another object.
Explanation:
If you bounce a ball, it will fly back up, but it will fall down again because of gravity. The cause is GRAVITY and the effect is the ball FALLINg. Now, because o fgravity, when the ball bounces up again, it will only bounce 1/2 the hieght, having another cause and effect. As gravity pushes down on objects, the more an object is effected by it, the more presure it will have.

how would you describe the forces between the particles of solids??
Answers
Answer:
Explanation:
In a solid, the attractive forces keep the particles together tightly enough so that the particles do not move past each other. ... The kinetic energy of the molecule is greater than the attractive force between them, thus they are much farther apart and move freely of each other.

Does combustion need oxygen?
A. Yes
B. No
Answers
Answer: a. Yes
Explanation:
Answer:
A. yes
Explanation:
In order to burn this fuel, oxygen is needed, as it is with any fire. The waste products from the combustion process are water and carbon dioxide. Thus, we breathe because oxygen is needed to burn the fuel (sugars and fatty acids) in our cells to produce energy The air we breathe contains about 21% oxygen.

What type of weathering creates a granite Tor?
Physical or
Chemical or
Biological
Answers
Answer:
Physical
Explanation:
Physical weathering is defined as the geological process in which rocks are broken down but there is no change in their chemical composition.
Granite tor are the rock masses above the ground surface which are associated with granites
Granite Tor is an example of physical weathering as they formed by freeze–thaw weathering. Granite tor are formed when magma present in the crust cools down and form batholith. Rocks above batholith gets erodes and left the batholith to expose.
Hence, the correct answer is "Physical weathering'.

please help me out i will give you brainlist. 0.500 is wrong
Answers
============================================
Work Shown:
Using the periodic table, we see that
1 mole of carbon = 12 grams1 mole of oxygen = 16 gramsThese are approximations and these values are often found underneath the atomic symbol. For example, the atomic weight listed under carbon is roughly 12.011 grams. I'm rounding to 2 sig figs in those numbers listed above.
So 1 mole of CO2 is approximately 12+2*16 = 44 grams. The 2 is there since we have 2 oxygens attached to the carbon atom.
-------------------
Since 1 mole of CO2 is 44 grams, we can use that to convert from grams to moles.
11.0 grams of CO2 = (11.0 grams)*(1 mol/44 g) = (11.0/44) mol = 0.250 mol of CO2
In short,
11.0 grams of CO2 = 0.250 mol of CO2
This is approximate.
We don't need to use any of the information in the table.
