Answer:
163.4 or m2/s
Explanation:
The rate of change of the radius is 1 m/s
The area of a circle is
We differentiate this to get the rate of change of the area with the radius:
The rate of change of the area is
At r = 26 m,
Answer:
Mechanical energy is the energy that is possessed by an object due to its motion or due to its position. Mechanical energy can be either kinetic energy (energy of motion) or potential energy (stored energy of position).
Hope this helps! :)
Explanation:
MA = (Effort Distance)/(Effort Resistance) = L/H
L = MA * H = 5 * 8" = 40"
You have a point on a rectangular graph with coordinates (6, 8).
You want to describe the same location in polar coordinates ... R and Θ .
-- 'R' is the distance from the origin to the point.
-- 'Θ' is the angle you'd need to turn the x-axis counterclockwise
around the origin to make it pass through the point.
To change rectangular coordinates to polar coordinates:
R = √(x² + y²)
Θ = the angle whose tangent is (y / x) .
(6i + 8j) is the [Cartesian] vector that takes you from the origin to (6, 8) .
R = √(6² + 8²) = √(36 + 64) = √100 = 10
Θ = tan⁻¹ (8/6) = 53.13° (rounded)
In polar coordinates, the same point is 10 ∠53.13° .
Answer:
It takes over eight minutes
To reach Saturn, the next closest planet, would take another 36 minutes, and a further three hours or so to reach Pluto.
