Displacement equals (velocity times time) + 1/2 *(acceleration * time squared). =. (10*4) + 1/2 * (2*2^2) = 56 meters
Answer:
2.A flowerpot falling from a balcony
Explanation:
Potential energy is the internal energy within a body at rest or at a height above the ground. In this case of the falling flowerpot, the flowerpot initially has a potential energy due to its position on the balcony above the surface of the earth. As the flowerpot falls, the work done against gravity in taking the flowerpot to this height on the balcony (equivalent to the potential energy) is transformed into the kinetic energy of motion as the flowerpot falls down through the height.
The answer is crystalline solid. Crystalline solids have a regular arrangement of particles, because of that, they possess definite geometry.
This means that if you take a look at the crystal under the microscope you would notice that there is a pattern that constantly repeats. This pattern is called a unit cell, and crystal is made up of stacked unit cells.
Answer:
Sonia will experience repulsion in two balloons
Explanation:
Here when we rub the balloon with the woolen cloth then due to friction between the cloth and balloon electrons from balloon will transfer to woolen cloth.
Due to transfer of electron the balloon will get positive charge which is given by
![Q = Ne](https://tex.z-dn.net/?f=Q%20%3D%20Ne)
so here since both balloons are rubbed against woolen cloth so both balloon will get some positive charge
now we know by the property of charge that two similar charges will always repel each other so here two balloons will repel each other after they rubbed against woolen cloth.
