The potential energy is defined as Ep=m*g*h where m is the mass of the body, g=9.81 m/s² and h is the height of the body. In our case m=0.01 kg and h=1.5 m. So when we input the values into the equation:
Ep=0.01*9.81*1.5= 0.14715 J.
So the potential energy of a grape is Ep=0.14715 J.
Answer:
Weight
Explanation:
"An object will float if the buoyancy force exerted on it by the fluid balances its weight, i.e. if FB=mg F B = mg . But the Archimedes principle states that the buoyant force is the weight of the fluid displaced. So, for a floating object on a liquid, the weight of the displaced liquid is the weight of the object."
Hope this helps! :)
A hammer is a type of lever.
Melting ice is not a chemical reaction, but is a physical change. There is no chemical reaction involved during the melting process, and it is still the same molecular substance.
Answer:
Vertex: Point where the principal axis and mirror meet
Focal point: Point we are reflected light converges or appears to diverge
Focal length: distance from the center of a mirror to the focal point
Principal axis: line that runs to the center of curvature to a mirror
Center of curvature: sensor of spherical mirror from which a curved mirror was cut
