The sum of all forces=m(mass) times a(acceleration). F=5.5(kg)*4.2(m/s^2)= 23.1N or D.
Answer:
2 meters
Explanation:
time is directly proportional to temperarure where distance is the constant k
therefore
T = t x 2a
28=7 x 2a
28= 14a
a=2m
Answer with explanation:
The given vectors in are reduced to their componednt form as shown
For vector A it can be written as
Similarly vector B can be written as
Hence The sum and difference is calculated as
The direction is given by
with positive x axis.
Similarly
The direction is given by
with positive x axis.
Answer:
The resulting charge on the initially neutral rod will be 3.) it will be negatively charged.
Explanation:
If the neutral rod is brought close to the neutral one and if the neutral rod is touching the ground then the positive charges will attract electrons from the ground on to the rod.
The Earth (or ground) has electrons in abundance and electrons can be taken from of fed into the Earth without having any significant impact on the Earth's electric field.
So. the resulting charge on the initially neutral rod will be 3.) it will be negatively charged.
