An electron is pushed into an electric field from infinity where it acquires a 1-V electrical potential. Suppose instead that two electrons are pushed from infinity the same distance into the same electric field. The electrical potential of the two electrons is ___________.a) 0.5V
b) 1V
c) 0.25V
d) 4V
e) 2V
Answers
Answer:
The electrical potential of the two electrons is 1 V.
(b) is correct option.
Explanation:
Given that.
Electric potential = 1 V
We know that,
The electric potential depends on the distance.
The electric potential does not depend on the charge.
The formula of electric potential
Where, E = electric field
d = distance
Hence, The electrical potential of the two electrons is 1 V.

Therefore:
As the runner was travelling for 9 seconds, he covered a distance of 99.9 metres. 9 seconds x 9 seconds = 81 seconds squared, and the runner covers roughly 1.23 metres in distance every second squared.
Explanation:
Acceleration=
Time
FinalVelocity−InitialVelocity
Therefore:
\begin{gathered}Acceleration=\frac { 11.1\quad m/s\quad -\quad 0\quad m/s }{ 9\quad seconds } \\ \\ =\frac { 11.1\quad m/s }{ 9\quad seconds } \\ \\ =1.23\quad m/{ s }^{ 2 }\quad (2\quad decimal\quad places)\end{gathered}
Acceleration=
9seconds
11.1m/s−0m/s

Ammonia is a weak base because it produces hydroxide (OH-) ions in solution.
Why is ammonia a weak acid?
Ammonia is a weak base because it produces hydroxide ions (OH-) in solution.
When ammonia dissolves in water, it accepts a proton from water, forming the ammonium ion (NH4+), and leaves hydroxide ions behind. This partial dissociation results in a small concentration of hydroxide ions, causing the solution to be slightly basic.
Unlike strong bases, which fully dissociate and release a large number of hydroxide ions, ammonia's limited ability to produce hydroxide ions makes it a weak base.

Contraceptives are items used or taken to prevent conception. These are birth control pill, patch, ring, IUD, birth control shots, and condoms. Among these contraceptives, condoms are the only type of birth control that prevents STIs or Sexually Transmitted Infections.
All contraceptives prevent STIs is False because not all them are used in STI prevention.
What is contraceptives about?
Not all contraceptives prevent sexually transmitted infections (STIs). Only condoms, dental dams, and some internal condoms, such as the female condom, can help prevent the transmission of STIs.
Other forms of contraception, such as birth control pills, the patch, the ring, and the shot, do not protect against STIs. This is because they work by preventing ovulation or by thickening the cervical mucus, which makes it more difficult for spermto reach the egg. They do not prevent the transmission of STIs because they do not block the exchange of bodily fluids, which is how STIs are spread.
So, the answer is false.
