Question

Prove that :-

Spammers stay away..!!​

Answer 1

Step-by-step explanation:

$\huge\mathcal{\fcolorbox{aqua}{azure}{\red{♡Answer★}}}$The core has positive charge, the electrons have negative charge. When you are rubbing the glass rod with the silk cloth, electrons are stripped away from the atoms in the glass and transferred to thesilk cloth. This leaves the glass rod with more positive than negative charge, so you get a net positive charge

3. Cofunction Identities.

• sin(90° - x) = cos(x) or cos(90° - x) = sin(x)
• tan(90° - x) = cot(x) or cot(90°- x) = tan(x)
• sec(90° - x) = cosec(x) or cosec(90°-x)= sec(x)

4. Pythagorean identities.

• Cos²A + sin²A = 1
