It is basically shielding a magnetic field. This can be done with rubber or any other material that is thick. Normally small magnets already block the shield.
Answer:
false
Explanation:
Linear momentum is the product of an objects mass and velocity
p=m×v
Explanation:
Given:
Δy = 6 m
v₀ = 0 m/s
a = 9.8 m/s²
Find: v
v² = v₀² + 2aΔy
v² = (0 m/s)² + 2 (9.8 m/s²) (6 m)
v ≈ 10.8 m/s
Round as needed.
The effort applied : 200 N
<h3>Further explanation</h3>
Equilibrium rotation
F₁.d₁-F₂.d₂=0
F₁.d₁=F₂.d₂
F₁=500 N
d₁=0.5 m
d₂=1.75-0.5=1.25 m
Answer:
2. Dot Product
Explanation:
The calculation of the electric flux gives an scalar result.
When we tray to calculate how much electric field passes trough a surface, we are calculating a scalar value. Furthermore, the concept of flux requires the calculation of a scalar value.
Also it is necessary to take into account that the magnitude of the flux trough a surface depends of the inclination of the surface respect to the direction of the electric field. This is taken into account sufficiently by a dot product.
Then, the answer is:
2. Dot Product
