600/3 = 200
the slope is 200m/min
OR
600/ (3/60) =
600 x 60/3 =
600 x 20 = 12,000 meters per hour
Answer:
Artificial weight = 70.27 N = 15.80 lbs
Explanation:
The earth weight of the astronaut = 160 lbs = 711.72 N
The weight on earth = m × g(earth)
g(earth) = 9.8 m/s²
711.72 = m × 9.8
m = (711.72/9.8)
m = 72.62 kg
But at the space station, the space station rotates once every 70 s to create an artificial radial acceleration that creates a radial gravity pulling the objects on the space station towards the centre of that space station.
radial acceleration = α = (v²/r)
v = rw,
α = (rw)²/r
α = rw²
r = radius of rotation = 120 m
w = angular velocity = (2π/70) (it completes 1 rotation, 2π radians, in 70 s)
w = 0.0898 rad/s
α = 120 × (0.0898²)
α = 0.968 m/s²
Artificial weight = (mass of astronaut) × (Radial acceleration) = 72.62 × 0.968
Artificial weight = 70.27 N = 15.80 lbs

Answer:
v = rw
Explanation:
When an object is rolling continuously without slipping, then every angle it rotates through, is equal to a distance the perimeter has rotated.
If the object completes 10 revolutions and takes a particular time, let's say t to complete it. The angular distance would then be 20 π rad, while its angular velocity will be 20 π/t
The circumference will somehow translate to the distance it covers, which is 20πr, this means that the speed is 20πr/t
So, like the question asked, the linear speed compared to angular speed is
v : w
20πr/t : 20πt, which can be simplified to
r : 1
In essence, v = rw
When light is reflected by a mirror, the angle of incidence is always <span>A. equal to the angle of reflection. We know this by the Law of Reflection.</span>
