Tomtit [17]

Inertia: tendency of an object to resist changes in its velocity. An object at rest has zero velocity - and (in the absence of an unbalanced force) will remain with a zero velocity. Such an object will not change its state of motion (i.e., velocity) unless acted upon by an unbalanced force.

A spring is compressed 8 cm. It is then brought back to equilibrium and compressed 24 cm. How much more work is done in the seco
posledela

Answer:

Nine times

Explanation:

x_{i} = Initial compression of the spring = 8 cm = 0.08 m

x_{f} = Final compression of the spring = 24 cm = 0.24 m

k = Spring constant of the spring

Initial spring energy is given as

U_{i} = (0.5) k x_{i}^{2}\\U_{i} = (0.5) k (8)^{2}\\U_{i} = 32 k

Initial spring energy is given as

U_{f} = (0.5) k x_{f}^{2}\\U_{f} = (0.5) k (24)^{2}\\U_{f} = 288 k = (9) (32) k = 9 U_{i}

Near the earth's surface, the electric field in the open air has magnitude 150 N/c and is directed down towards the ground. If t
kati45 [8]

Hi there!

Using the equation for the electric field produced by an infinite sheet of charge:

E = \frac{\sigma}{2\epsilon_0}

E = Electric field strength (150 N/C)

σ = Surface charge density (? C/m²)

ε₀ = Permittivity of free space (8.8542× 10⁻¹² C²/Nm²)

We can rearrange the equation to solve for the surface charge density (charge per unit area)

E = \frac{\sigma}{2\epsilon_0}\\\\\sigma = 2E\epsilon_0\\\\\sigma = 2(150)(8.8542*10^{-12}) = \boxed{2.656 \times 10^{-9} \frac{C}{m^2}}
