Answer:
The time rate of change of the electric field between the plates is
Explanation:
From the question we are told that
The radius is
The distance of separation is
The current is
Generally the electric field generated is mathematically represented as
Where is the permitivity of free space with a value
So the time rate of change of the electric field between the plates is mathematically represented as
But
So
substituting values
Answer:
83%
Explanation:
On the surface, the weight is:
W = GMm / R²
where G is the gravitational constant, M is the mass of the Earth, m is the mass of the shuttle, and R is the radius of the Earth.
In orbit, the weight is:
w = GMm / (R+h)²
where h is the height of the shuttle above the surface of the Earth.
The ratio is:
w/W = R² / (R+h)²
w/W = (R / (R+h))²
Given that R = 6.4×10⁶ m and h = 6.3×10⁵ m:
w/W = (6.4×10⁶ / 7.03×10⁶)²
w/W = 0.83
The shuttle in orbit retains 83% of its weight on Earth.
Answer:
Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.
Example: Radio waves, microwaves, visible light, and x rays
