Answer:
gas, liquid and the last one is opaque solid
Explanation:
Answer:
• let's first get time
• let's find horizontal displacement
- g is acceleration due to gravity [ vertically: g is 10 m/s². horizontally: g is 0 ]
Answer: 9. 9 times force
8. 7000 N/C directed towards q₂
Explanation:
9.
Let the two charges be and separated by distance r. Then the force of repulsion is given as :
where, k is the Coulomb's constant.
When the magnitude of the charges is tripled: and , the new force of repulsion, force' is:
8.
The electric field is given by:
where q is the charge and r is the distance of the point from the charge where electric field is required to be found.
It is given that,
Electric field due to charge at point a is:
Electric field due to charge at point a is:
Thus, net electric field due to both charges at a is
Like I said. It’s annoying. But I appreciate you doing this for new people.
The term <u>c</u><u>e</u><u>l</u><u>l</u> is incorrect because, the average voltage of a cell is 3.40 V and as already mentioned in question, the volt of source is 18 V, so cell couldn't be the appropriate word, actually the source is <u>b</u><u>a</u><u>t</u><u>t</u><u>e</u><u>r</u><u>y</u><u>.</u>
Now, the source is most likely related to cell because a <u>b</u><u>a</u><u>t</u><u>t</u><u>e</u><u>r</u><u>y</u> which is the source here, is made up of a "group of cell".
