Answer: 5.68g/ML.
Explanation; Divide the mass of the unknown substance and the volume of the unknown substance and you will have your answer.
Hope this helps! ^^ if you can pls mark me brainiest!
When marble is flicked off the edge of a table then the at the instant it will move off the table the velocity is horizontal while due to force of gravitation the marble will start accelerating downwards.
So here we will say that the velocity of marble will remain constant through out the motion in X direction as there is no force in that direction
While in Y direction the marble will have gravitational force due to which marble will accelerate downwards
So the path of the marble will be parabolic path
hence the correct answer will be
<em>A.
</em>
<em>Only one continuous force is acting on the marble.</em>
It's called induced charge separation I believe.
Answer:
If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm's Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω.
