Answer:
(a) It will take 12.82 sec to come into rest
(b) After calculation distance is 737.15 m which is less than 800 m so jet can land on the island
Explanation:
(a) When the jet lands at the ground its velocity is 115 m/sec
So initial velocity u = 0 m/sec
Finally jet will stop so its final velocity will be zero v = 0 m/sec
Maximum acceleration
So minimum time,
So
t = 12.82 sec
(b) Average speed
Distance traveled in 12.82 sec =
As this distance is less than 800 m so jet can land on the island
Noise could be defined as electromagnetic fields that affect analog signals that are constantly changing. This process does not occur in a similar way with digital signals, which have fixed electrostatic pulses (For this reason they are able to withstand 'noise' because the power of these signals are much stronger than the power coming from noise).
That phenomenon does not happen with the analog signals which have a variable intensity and become vulnerable to any electronic noise interference.
When very high electromagnetic fields are generated, the waves of the analog signal cannot be perceived which causes problems in the transmitted signal (making it unintelligible to the receiver)
If both particles have the SAME electrical charge, then they repel.
If they have DIFFERENT electrical charge, then they attract.
Protons have + charge .
Electrons have - charge .
So two protons (A) or two electrons (D) push apart.
One proton and one electron (C) pull together.

Answer:
<em>Both charges are of the same sign (positive or negative) and with a value of 3.73 ηc.</em>
Explanation:
<u>Coulomb's Law</u>
The electrical force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between the two objects.
Written as a formula:
Where:
q1, q2 = the objects' charge
d= The distance between the objects
We know both charges are identical, i.e. q1=q2=q. Since the force is repulsive, both charges are positive or negative.
We also are given the force between them:
And also the distance
d=25 cm = 0.25 m
Substituting all into the formula:
The product of . Operating:
Operating:
Solving for q:
Both charges are of the same sign (positive or negative) and with a value of 3.73 ηc.
