A 40 kg-skier is standing at the top of a 12-meter high slope. What is her potential energy? PE = m x g x h (g = 10m/s2) A. 6000J B. 48J C. 4800J D. 400J
Answer:
The correct option is;
C. 4800 J
Step-by-step explanation:
The given parameters are;
The mass of the skier = 40 kg
The height of the slope = 12 meter
The acceleration due to gravity, g = 10 m/s²
The potential energy, PE, is given by the formula PE = Mass, m × Acceleration due to gravity, g × Height, h
Substituting the values, gives
The potential energy, PE = 40 kg × 10 m/s² × 12 m = 4800 kg·m²/s² = 4800 J
The potential energy, PE = 4800 J

What is an equation in point-slope form of the line that passes through (-7,1) and (-3, 9)
Step-by-step explanation:
let eqn be y - y1 = m(x - x1)
m = (9 - 1)/(-3 - (-7))
m = 2
sub (-7, 1):
y - 1 = 2(x + 7)
therefore, the equation is y - 1 = 2(x + 7)

An NBA Basketball court is a rectangle that is 94 feet long and 50 feet wide. What is the area of the court? What is the perimeter of the court?
Area= Sq.feet
Perimeter= Feet
Answer:Area = 4700 feet squared
Perimeter= 288 feet
Step-by-step explanation:
Length = 94 feet
Width = 50 feet
Area = Length × Width
= 94 feet × 50 feet
= 4700 feet squared
Perimeter = 2(Length + Width)
= 2(94 feet + 50 feet)
= 2(144 feet)
= 288 feet

Find the center and radius of the circle given by this equation: x^2 - 10x + y^2 + 6y - 30 = 0
Answer:
center=(5,-3)
radius = 2 unit
Step-by-step explanation:
Center with the equation x² - 10x + y² + 6y - 30 = 0 is (5, -3) and the radius is 8 units.
Circle with the given center and radius: Equation of a circle with the center (h, k) and radius 'r' is given by,
(x - h)² + (y - k)² = r²
Here, Center of the circle → (h, k)
Radius of the circle → r units
Given equation of the circle in the question is,
x² - 10x + y² + 6y - 30 = 0
Convert this equation to the standard equation of the circle.
x² - 2(5x) + y² + 2(3y) - 30 = 0
[x² - 2(5y) + 5²] - 5² + [y² + 2(3y) + 3²] - 3² = 30
(x - 5)² - 25 + (y + 3)² - 9 = 30
(x- 5)² + (y + 3)² = 64
(x- 5)² + (y + 3)² = 8²
Therefore, center of the circle is (5, -3) and radius of the circle is 8 units.

Which of the following best shows two elements combining to form a compound!? Explain...
Chemistry.
Answer:
C because elements are form by atoms and when we study about atom we draw atom like circle
so, that's why I think C is correct
Step-by-step explanation:
Option C best shows two elements combining to form a compound.
What is molecular structure?The term "molecular structure" refers to the structure of a molecule that merely consists of the arrangement of its atoms.
A chemical compound is a material made of several similar molecules that are linked together by chemical bonds and are made up of atoms from various elements.
Chemical compounds cannot be created when two atoms of the same element are bound together since this would need the presence of two distinct elements.
In diagram C it is obtained that atoms are combined to form the compound.
The finest example of two components combining to make a compound is in Option C.
Hence, option C is correct.
