Explanation:
Answer:
They fold to create ridges and valleys perpendicular to the direction to which pressure is applied.
Answer:
Option C : 290 J
Explanation:
We can use conservation of energy to estimate the kinetic energy when the object hits the ground:
When the object is at its initial height of 15 meters, it velocity is zero (falls from this position), therefore the total energy it possesses is due to potential energy given by the expression:
Joules
At the moment the object hits the ground from its free fall, its potential energy is zero, while its kinetic energy must equal the rest. So at that moment the object's kinetic energy must be 294 Joules.
Answer:
Zero...
Explanation:
When the glass road is rubbed with silk clothes, it get charged positively. When it made contact with the metallic rod, the positive charge is transferred to the metallic rod (The wooden post will have no effect because it doesn't interact with charge on metals). When the metallic rod make contact with ground with intact glass rod, all the charge transfers to the ground because of the high negative potential of Earth, So, in the end all the net charge become zero.
