Discuss renewable and nonrenewable resources. Give at least two advantages and two disadvantages of each. (4 points)
Thepotemich [5.8K]
Renewable resources-resources which get renewed or replenished quickly. e.g..solar and wind energy.

non renewable resources-resources which have a limited stock. once this stock is exhausted it may take years to get renewed or replenished.eg.coal,petroleum,natural gas.

I know only the definitions advantages I don't know.
SORRY.

A 6 kg mass collides with a body at rest .After collision they travel together with a velocity equal
Mars2501 [29]

Answer:

12 kg

Explanation:

Momentum before collision = momentum after collision

m₁ u₁ + m₂ u₂ = m₁ v₁ + m₂ v₂

After the collision, they have the same velocity, so v₁ = v₂ = v:

m₁ u₁ + m₂ u₂ = m₁ v + m₂ v

m₁ u₁ + m₂ u₂ = (m₁ + m₂) v

We know that m₁ = 6 kg, u₂ = 0 m/s, and v = u₁ / 3.

(6 kg) u₁ + m₂ (0 m/s) = (6 kg + m₂) (u₁ / 3)

(6 kg) u₁ = (6 kg + m₂) (u₁ / 3)

6 kg = (6 kg + m₂) (1/3)

18 kg = 6 kg + m₂

m₂ = 12 kg

An aluminum wire with a diameter of 0.115 mm has a uniform electric field of 0.235 V/m imposed along its entire length. The temp
tekilochka [14]

Answer with Explanation:

We are given that

Diameter of coil=d=0.115mm

Radius, r=\frac{d}{2}=\frac{0.115}{2}=0.0575mm=0.0575\times 10^{-3} m

Using 1mm=10^{-3} m

Electric field=E=0.235V/m

T=55 degree C

T_0=20^{\circ} C

\rho_0=2.82\times 10^{-8}\Omega m

\alpha=3.9\times 10^{-3}/C

(a).We know that

\rho=\rho_0(1+\alpha(T-T_0))

Substitute the values

\rho=2.82\times 10^{-8}(1+3.9\times 10^{-3}(55-20))

\rho=3.2\times 10^{-8}\Omega m

(b).Current density,J=\frac{E}{\rho}

Using the formula

J=\frac{0.235}{3.2\times 10^{-8}}=7.3\times 10^6A/m^2

c.Total current,I=JA

Where A=\pi r^2

\pi=3.14

Using the formula

I=7.3\times 10^6\times 3.14\times (0.0575\times 10^{-3})^2

I=0.076A

d.Length of wire=l=2m

V=El

Substitute the values

V=0.235\times 2=0.47 V

What kind of front occurs when a cold air mass replaces a warm air mass?
Andreyy89

Answer:

Explained below:

Explanation:

When a cold air mass meets a warm air mass, a front is formed and if the cold air is replacing the warm air, it is known as a cold front. Cold fronts frequently cause thunderstorms or rain showers because they pressure the air in a steep upward direction at the front's edge. They are also responsible to bring the changes in atmospheric pressure and wind direction.
