Answer:If a circle was flattened by pushing down on it, it would most likely form into the shape of <em><u>ellipse </u></em>which has <em><u>two </u></em>focal points.
Explanation:
Ellipse is curve in a plane with two focus points. The sum of the distance of one point from both fixed points or focal points in the plane remain constant.
When circle was flattened by pushing it deform to plane shape likely to the shape of ellipse.
Answer:
The electric field is
Explanation:
From the question we are told that
The radius of the metal sphere is
The excess charge which the metal sphere carries is
The distance of the position being to the center is
The coulomb constant is
Generally the electric field is mathematically represented as
substituting values
Answer:
Explanation:
Unit conversions:
1890 km/h = 1890 km/h * 1000m/km * 1/3600 h/s = 525 m/s
5.2 km = 5200 m
Assume that the jets is traveling in perfect circular motion, we can calculate the centripetal acceleration of the motion:
where v = 525m/s is the velocity of the jet and r = 5200 is the radius of the arc
