Answer:
A. 30.7cm
B.
C. The electric field is directed away from the point of charge
Explanation:
A.
B.
Considering Gauss's law
C. The electric field directed away from the point of charge when the charge is positive.
The energy stored in the spring is 2.25 J.
Given that the energy stored in a spiral spring is E = 1/2 k e^2
Where;
E = energy stored in the spring
k = force constant
e = extension
We can obtain the force constant as the slope of the graph;
k = 25 - 5/0.5 - 0.1
k = 20/0.4
k = 50 N/m
Substituting into the equation when e = 0.3,
E = 1/2 × 50 × (0.30)^2
E = 2.25 J

Answer:
the Earth magnetic field in that region is about 89.09 T
Explanation:
If the magnetic field has an inclination of , and its horizontal component is 17 microTesla, then we can calculate the magnitude of the full magnetic field via the cosine function. Notice that the decomposition of a vector in horizontal and perpendicular components originates a right angle triangle where the vector is the hypotenuse of the triangle.

Explanation:
it says venus is often named as the earth's twin because both the planets share a similar size, surface composition and have an atmosphere with a complex weather system. But if you go in depth, the earth is just a little bit bigger than venus and both the planets move in opposite direction of eachother
The answer should be D. H2O
