<span>The answer is "0.5N".
According to the question;
P1=P2
so,
F1/A1= F2/A2
P=(F/A)
A1=100mm</span>²
<span>
F1= 10N
A2= 5mm</span>²
<span>
F2= ?
F2= ((F1 x A2)/A1)
= ((10 x 5) /100)
=50/100
=0.5N</span>
Answer:
A. The potential energy of the positively charge proton from 5v to 7.5v will increase because in an electric field work is done on the proton to move it to a point of higher potential
B. when an electron is moved from 7.5v to 5v it loses potential energy due to the charges lost so as to bring it to a point of lower potential
Explanation:
It means every thing is made out of Atoms and some things are element componds so elements are the "backbone" of the compounds.
When I ride the train, the song of the train whistle is an example of the Doppler Effect. Because a train is at the center of sound waves it produces, which radiate in concentric circles around it, there is no difference between the sound heard by someone on the platform, and the sound of the train as heard by someone standing behind the caboose.
