41,32,23,3632 °Fahrenheit
278.15,273.15,268.15°kelvin.
To turn °c to °f, what I learned is divide by 5, multiply by 9, then add 32
To turn °c to°k is add 273.15.
ΔK = -2334.66J. The kinetic energy loss is -2334.66J.
This is an example of elastic collision which means that the two bodies remain united after the collision, as we know the amount of movement is preserved that is called conservation of momentum. So, we can write the equation as follow:
Where is the initial momentum and is the final momentum.
Substituting the values:
After the collision the bodies are united and move at the speed of 33.33 m/s.
To calculate the kinetic energy lost in the impact we only have to calculate the energy of each body before the impact and compare it with the energy of the whole after the impact.
ΔK =
ΔK =
Substituting the values:
ΔK =
ΔK =
ΔK =
ΔK =
ΔK =
ΔK =
Answer:
Rusting of iron is slow in desert area because rusting happens when iron articles react with atmospheric oxygen and moisture and produced a substance called rust. in desert areas there is less moisture in air as compared to coastal area therefore rusting is slow.
Answer:
D)they would generate so much power that they would blow themselves apart.
Explanation:
Stars contains helium and hydrogen gases with helium forming a large percentage. When a star is a few times greater than the Sun it could cause it to collapse into a black hole.
However when the mass of the star is 200 times greater than the sun, it means a larger percentage of helium gas which is formed by the fusion of hydrogen nuclei with a large amount of energy being the by product of this fusion process. This would make the Stars generate so much power that they would blow themselves apart.
Answer:
C
Explanation:
From the question we are told that a vector on the x and y plane face their negative axis
Generally in the x and y plane thr negative y axis is made to face down opposite the positive y axis
Whilst the negative x axis faces the left which is also alternate to the positive x axis
Generally A vector pointing towards the x and y negative axis fro the origin (0) will definitely be in the third quadrant
