F - False.
The law of conservation of momentum states that the total momentum is conserved.
Answer:
measure the position every so often with a stopwatch
Explanation:
A possible method of measurement is to place a measuring tape along the path and measure the position every so often with a stopwatch, with this we can make a graph of position against time and by extrapolation find the initial velocity.
This is a method used in measurements of uniform movements of bodies
The beginning of the Phanerozoic is marked by the development of hard body parts, such as shells and bones.
Answer:
The electric field at origin is 3600 N/C
Solution:
As per the question:
Charge density of rod 1, 
Charge density of rod 2, 
Now,
To calculate the electric field at origin:
We know that the electric field due to a long rod is given by:
Also,
(1)
where
K = electrostatic constant = 
R = Distance
= linear charge density
Now,
In case, the charge is positive, the electric field is away from the rod and towards it if the charge is negative.
At x = - 1 cm = - 0.01 m:
Using eqn (1):
(towards)
Now, at x = 1 cm = 0.01 m :
Using eqn (1):
(towards)
Now, the total field at the origin is the sum of both the fields:
Answer:
c) both technician A and B
Explanation:
- A communication network is a collection of the interconnected networks that are managed to support the transfer of the information form a user in one network location and to a user of the another node.
- Are connected as the link and to enable the communication and sharing of the data between the terminals and different modules. Hence both the A and B technicians are equally correct.
