Foraging bees often move in straight lines away from and toward their hives. Suppose a bee starts at its hive and flies 500 m du
1 answer:
Answer:
The distance of the bee from the hive is 740 m.
Explanation:
Given that,
Bee starts fly 500 m due east, 430 m west and 670 m east.
The direction of the bee
500 m in positive direction
430 m in negative direction
670 m in positive direction
We need to calculate the net distance
Using formula of distance
Hence, The distance of the bee from the hive is 740 m.

Hi there!
Begin by using Gauss' Law to find the electric field.
E = Electric field (N/C)
dA = differential area element
Q = enclosed charge (C)
ε₀ = Permittivity of free space (8.85 * 10⁻¹² C²/Nm²)
We can construct a large cylinder around the wire in order to determine the electric flux. The electric field lines will pass through the LATERAL surface area of the cylinder, so:
Where 'L' is the length of the cylinder and 'r' is the distance from the capacitor.
The enclosed charge is equivalent to the charge per meter length (λ) multiplied by the length, so:
We can rewrite the dot product as EA (where cosθ = 1 since the normal vector points in the direction of the field).
A = the lateral surface area of a cylinder, so:
Rearrange to solve for 'E'.
a)
Plug in the distance into 'r'.
b)
Repeat:
We can see that the distance from the wire is INVERSELY related to the electric field strength by a power of r⁻¹. The field strength DECREASES as the distance INCREASES.
