Definitely the first: the water molecule is polar. :)
Answer:
The work done is equal to zero = 0
Explanation:
Let us remember that the definition of physical work is given by the product of force by the displacement of the body.
![Work=F*d\\\\where\\F= force [N]\\d=distance [m]\\replacing\\Work=1115*(0) = 0](https://tex.z-dn.net/?f=Work%3DF%2Ad%5C%5C%5C%5Cwhere%5C%5CF%3D%20force%20%5BN%5D%5C%5Cd%3Ddistance%20%5Bm%5D%5C%5Creplacing%5C%5CWork%3D1115%2A%280%29%20%3D%200)
Answer:
4.3 g/ cm^3
Explanation:
Mass / Volume = density . so 2150/500= 4.3 g/cm^3
Answer:
option (a)
Explanation:
The magnetic field is produced by the electric current, and the direction of magnetic field is given by the Maxwells' right hand rule.
The magnetic field is also be produced by the time varying magnetic fields.
Answer:
For the purposes of your question, we can think of speed and velocity as being the same thing. Therefore, the kinetic energy of an object is proportional to the square of its velocity (speed). In other words, If there is a twofold increase in speed, the kinetic energy will increase by a factor of four.
