<span>A mountain is a type of constructive force. This is because the mountains are formed (or "constructed") through the convergence of land plates. When the two (or more) plates come together, they cause the land at the fault line to shift upward, leading to the formation of mountains.</span>
I'm 99% sure that it's "D. Electric Field"
Answer:
Explanation:
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
= Mass of sphere = 2000 kg
= Mass of other sphere = 2.1 kg
r = Distance between spheres
Force of gravity is given by
The gravitational force is
The gravitational force is
Answer:
a) E = 7.57 10⁻⁵ N / C, b) B= 2.11 10⁻¹⁸ T, c) the magnitudes remain the same, but the sign of the responses change
Explanation:
a) The electric field due to a charged particle is
E = k q / r²
Let's look for the distance from the origin where the particle is to the point of interest
r² = (-3 10⁻³ -0)² + (-3 10⁻³ -0)²
r² = 19 10⁻⁶
The proton charge is
q = +1.6 10⁻¹⁹ C
Let's calculate
E = 8,988 10⁹ 1.6 10⁻¹⁹ / 19 10⁻⁶
E = 7.57 10⁻⁵ N / C
b) to calculate the magnetic field let's use the Biot-Savat law
B = μ₀/4π I / r²
The current is defined as the number of carriers per unit of time at a given point
I = q v
Let's calculate
B = 4π 10⁻⁷ /4π (1.6 10⁻¹⁹ 4 10⁴) / 19 10⁻⁶
B= 2.11 10⁻¹⁸ T
c) an electron has a charge of the same magnitude, but in the opposite direction, negative.
Therefore the magnitudes remain the same, but the senses (sign) of the responses change
