For the answer to the question above, <span>When a weather map shows a wind symbol at 270 it indicates that the wind is coming from the WEST.
I hope my answer helped you. Feel free to ask more questions. Have a nice day!</span>
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
Hope this Helps!!!
Answer:
Force, 
Explanation:
Given that,
A potential energy function for a system in which a two-dimensional force acts is of the form of :
We need to find the force that acts at the point (x, y). The force in 2 dimensional with components is given by :
So, the force acting at the point (x,y) is 
. Hence, this is the required solution.
Answer:
The best angular magnification is
-375
Explanation:
Fe = Fo - L
From the question, (Fo) = 1.08 cm while (L) = 0.56cm
Thus, Fe = 1.08 - 0.56 = 0.52cm
Now, let's apply the angular magnification equation ;
M = - Di/Do
Where Di is the distance from the lens to the image and Do is the distance of the object to the lens.
In this question, Di is represented by f which is the distance from the lens to the image and it is f= 195cm
Also,Do is represented by Fe which is 0.52cm and it is the distance of the object to the lens.
Thus m = - f/fe = - 195/0.52 = - 375
