Answer:
Liquid has a defined volume but undefined shape
Explanation:
Explanation:
Solid has specific shape and volume
Liquid has specific volume but no specific shape
Gases have no specific volume and no specific shape
So correct answer is liquid.
Answer:
Explanation:
Objects moving in circular path would be have either centripetal or centrifugal force.The force is either to center or away from center. When the object is moving along the circular path the centripetal force is
Here m is mass, v is velocity and r is radius of circular path
The acceleration is given by:
The point of interest is lowest point on circle.The acceleration of plane at this position point up.The speed of plane from radial acceleration equation is:
Substitute 17 m/s² for a and 450m for r
So
A. Negatively charged
B. Positively charged
