Answer:
Explanation:
As B has a y component of -5, A must have a y component of 5 to have the result lie on the x axis.
As B has an x component of 3 and the result has an x component of -4, A must have an x component of -7
A = (-7, 5)
magnitude A = √(7² + 5²) = √74 ≈ 8.60
θ = arctan(y/x) = arctan(5/-7) ≈ 144.46° CCW from the positive x axis
Explanation:
Power = work / time
Power = force × distance / time
P = (650 kg) (10 m/s²) (20 m) / (15 s)
P = 8667 W
You're talking about a <em>tornado</em>.
It's not so much the low pressure that's so dangerous in the center of a tornado. It's more a matter of the high winds that are <em>caused </em>by the low pressure.
Answer:
22cm
Explanation:
focal length = 11cm
radius of curvature,r = 2f
r= 2 x 11
r=22cm
Diagram A is the correct diagram
