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:
The one that holds it backward will experience a greater reaction force.
Explanation:
Newtons third law of motion states that in every action there is equal and opposite reaction. The action force of making the water leave the nozzle for the firefighter who holds the hose backwards is greater than that for the fire fighter holding it straight. The water requires a a greater momentum and force to make a u-turn before leaving the nozzle. Hence the reaction force for the hose held backwards is greater
Answer:
49 N (d)
Explanation:
w= mg = 5 kg * 9.8 m/s^2 = 49 N
Wood, marble, clay, terracotta and even concrete all come in colors and can be classified as natural materials.
Answer:
A) The hanging wall moves up.
C) The fault is at an angle.
D) The fault is caused by compression.
F) The plates are colliding.
Explanation:
the following statement are true about reverse faults.
A) The hanging wall moves up: a reverse fault is one that the hanging wall moves ups and the footwall moves down.
C) The fault is at an angle :reverse fault occur at less than 45 degree angle
D) The fault is caused by compression: reverse fault are cause by compressional stress where the hanging wall and footwall are pushed together.
F) The plates are colliding: the fault uses one or more plates that collide in movement.
