The formula for the volume of a cone is V = 1/3hπr^2
Formula of the Area of Triangle is
A = Base x Height
In the image, the sine A is equal to y/z and the cosecant of it is equal to z/y. To obtain the cosecant B, we must do the way we did to the angle A. Sine B is x/z and the cosecant B is equal to z/x, which is equal to the secant A. From this idea, we can say that:
sin(A) = cos(B)
cos(A) = sin(B)
csc(A) = sec(B)
sec(A) = csc(B)
tan(A) = cot(B)
cot(A) = tan(B)
The correct formula for cosecant ratio of angle b is:
csc(B) = hypotenuse/adjacent
Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared. Kinetic energy is usually measured in units of Joules (J); one Joule is equal to 1 kg m2 / s2.
Potential energy is energy an object has because of its position relative to some other object. When you stand at the top of a stairwell you have more potential energy than when you are at the bottom, because the earth can pull you down through the force of gravity, doing work in the process. When you are holding two magnets apart they have more potential energy than when they are close together. If you let them go, they will move toward each other, doing work in the process.
The formula for potential energy depends on the force acting on the two objects. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters. Notice that gravitational potential energy has the same units as kinetic energy, kg m2 / s2. In fact, all energy has the same units, kg m2 / s2, and is measured using the unit Joule (J).
Sum (r+s)= -b/a
Product (rs) = c/a
Example: give the sum and the product of the roots of the given equation :
answer : Sum = -3
+3x will become negative -3
Then, the product will never change .
*Given the roots , of the quadratic equation , identify the equation.
Example: 4 and 3
Product = 4 x3 =12
Remember : if the answer of the sum is positive change it into negative , then the answer of the product will never change
I hope it help!
Ca = 24.7% = 24.7g/40
H = 1.2% = 1.2g/1
C = 14.8% = 14.8g/12
O = 59.3% = 59.3g/16
Divide it by its atomic mass
Ca = 24.7g/40 = 0.62
H = 1.2g/1 = 1.2
C = 14.8g/12 = 1.23
O = 59.3g/16 = 3.71
Divide it by using the lowest value that resulted which is 0.62
Ca = 24.7g/40 = 0.62/0.62 = 1
H = 1.2g/1 = 1.2/0.62 = 2 (I rounded it off already)
C = 14.8g/12 = 1.23/0.62 = 2 (I rounded it off already)
O = 59.3g/16 = 3.71/0.62 = 6 (I rounded it off already)
(I am now uncertain of my answer)
where, m=mass of the object(kg), g=gravitational field strength(9.8m/s^2), h=height(m)
where, m=mass of the object(kg), v=speed of the object(m/s)
