The answers is
D. The acid creates cracks in the rocks, which
allow air to circulate through the rock,
causing it to weather
Answer:
Your project goes well.
Explanation:
Because that's how it works.
Answer:
The correct option is D
Explanation:
This question is incomplete because of the absence of the setup which as been attached below. The setup shows/determines/tests the friction of wood (which is a block material), since Jerry wants to test the friction between different types of materials, he will have to replace the wooden block with another type of block material of choice so as to determine the friction of that also.
In order to have a comprehensive experiment, Jerry can use 4-5 different types of block material in the course of the experiment.
Electric potential energy of a dipole is given as


so change in the potential energy is given by


here initially it was parallel to electric field while finally it is perpendicular to the electric field
so we have


so above is the change in potential energy of dipole
<span>D. When velocity at a maximum, acceleration is also at a maximum.
Acceleration is the rate of change of velocity so, it is directly proportional to it, hence, when it will increase velocity will also increase
