Answer:
5.213ft
Explanation:
Z² = x² + y²
x = √(z² - y²)
y = 52ft, dx = 6ft, z = 105ft, dz = ?
d(z² = x² + y²)
2zdz = 2xdx
dz = xdx/z
But x = √(z² - y²)
dz = √(z² - y²)/z * dx
dz = [√(105² - 52²)/105] * 6
dz = √(8521)/ 17.5
dz = 5.213ft
Answer:
how its outward appearance is changing
Explanation:
H-R diagram is a fundamental tool used to classify stars. The position of stars on the H-R diagram is dependent on its luminosity and temperature.
The position of the star is represented by its outward appearance specially the color. The hottest and brightest the star, the more it lies between the red and blue color range.
The cooler stars lie on the right side of the H-R diagram while the hot stars lie on the left side of the H-R diagram.
(hydrogen) is not a compound because it's not made of more than one element. Yes we have more than one component, but both components are of the same element H.
Something like 
is a compound because it's made of carbon and oxygen (specifically 1 carbon and 2 oxygen), so we have at least two different elements here.
