Answer:
Explanation:
According to ohm's law, we know that:
Where,
- Voltage (V) = 2000 Volts
- Current (I) = 200 Amperes
Substituting the values, we get:
→ 2000 = 200 × R
→ 2000/200 = R
→ 10 = R
Hence,
- <u>Required Resistance = 10 </u><u>o</u><u>hm</u>
The main purpose of gel electrophoresis is to separate the molecules based on their different electric charge.
Hope this helps!
Answer:
C ) Electric charge.
Explanation:
Amber is used in the experiments related to static electricity.
In electrostatics, elektron was the word used as a variation to amber, by the Greeks. Amber buttons, when rubbed with cloth, attracted hair.
Studies showed that when amber is rubbed with fur, fur became negatively charged and amber became positively charged. That is because amber loses its electrons to fur.
It would be "resonance" that is occurring that causes the nonvibrating tuning fork
<span>to begin to vibrate. Specifically the resonance of the sound waves that are traveling through air. </span>
Answer:
1) Unbalanced
2) Balance
3) Balanced
4) Unbalanced
5) Unbalanced
Explanation:
For 1 and 5, since the objects are not at a constant speed/velocity, their forces must be unbalanced.
For 2 and 3, their speeds are constant so that means the force is balanced. If the bycicle or box started accelerating, that would indicate an unbalanced force
For 4, the speed is constant, but it's direction is not indicating another unbalanced outside force causing it to turn. The force is unbalanced.
