Answer:
False
Explanation:
Carbon dioxide is made up of polar molecules, but the dipole moments cancel each other out. Therefore, not a polar molecule.
Answer:
The speed will be "3.4×10⁴ m/s²".
Explanation:
The given values are:
Angular speed,
w = 7200 rpm
i.e.,
=
=
Speed from the center,
r = 6.0 cm
As we know,
⇒ Linear speed,
On putting the estimated values, we get
Now,
Acceleration on disk will be:
⇒
Answer:
The answer is C. Kinetic energy
Explanation:
Generators don't actually create electricity. Instead, they convert mechanical or chemical energy into electrical energy. They do this by capturing the power of motion and turning it into electrical energy by forcing electrons from the external source through an electrical circuit.
Subtract one from the to find the magnitude. Whether it's positive or negative will determine the direction.
