Hope it helps
Non- mechanical wave does not need matter to carry energy.

Answer: "Deviation"
Explanation:
Magnetic fields of aircraft may sometimes mess with the wiring structure which can cause the compass to have a deviation or error!
Answer:
The distance between the particles have to be
x=0.01m or 1 cm
Explanation:
Using the law of Coulomb for two charge particles
Notice you don't know the value of K or q1 or q2 however the value is the same in both cases, so you don't need to know exactly the value of each one you can put constant in the equation like this:
C
Now to find r can use the value of K
Answer:
a. 156.41m
b. directly over the target
Explanation:
a) At the point of release, the weight will have:
Horizontal:
velocity of 40m/s (same as the plane)
Acceleration of zero since it is not under the influence of any force.
Vertical:
initial Velocity - zero at this instant
Acceleration - Towards the ground with g (9.81m/s^2)
from newton's equation of motion, since its falling under gravity, the horizontal component wont be involved
s = ut + (1/2)at^2
u = initial velocity
a = acceleration
s = displacement
t = time taken
75 = 0 + (1/2)(9.81)t^2
t^2=15.29
t=3.91
t = 3.91s
Applying the time of flight to the horizontal components:
Distance = speed x time
= 40 x 3.91
= 156.41m
B) The pilot looks down at the weight after she drops it. Where is the plane located at the instant the weight hits the ground?
not yet over the target
past the target
directly over the target
not enough information to determine
c. directly over the target. will be the correct answer
