The appropriate response is recycling aluminum products. Metal is a store in the Earths outside layer of at least one important minerals. The most profitable metal stores contain metals pivotal to industry and exchange, similar to copper, gold, and iron. Copper mineral is dug for an assortment of modern employments. Copper, an incredible conduit of power, is utilized as electrical wire.

Answer: recycling aluminium products

Ore is an aggregate of inorganic minerals, which are economically valuable. The ores are present in the rocks. The ores are extracted from earth through the process of mining. The minerals present in the ores are non-metals and metals.

Recycling of aluminium products is most useful for overcoming the disadvantage of using ores, because ores are non-renewable resources, which means that their abundance is low on earth and these resources once used cannot be replenish. Aluminium is a valuable metal extracted from ore, therefore, once used for a specific purpose as a product should be recycled in another form so that can be used again.

⭐Hey

⭐Here we can use the formula for the body that is in free fall state. .

⭐that is

↪V = underoot 2*g*h

↪So the velocity will be ...

↪V = underoot 2 * 10 * 100

↪V = underoot 2000

↪V = 20 *underoot 5

↪V = 20 ( 2.23)

↪V = 44.6 m/s

Create a Graph : Include numbers, axes, and order pairs
dlinn [17]
Answer:

a) Peak value = 20

b) Average value = 9.0

c) RMS value = 14.15

Explanation:

The peak-to-peak value = 40

v_{p-p}=40\begin{gathered} v_{p-p}=2v_p \\  \\ 40=2v_p \\  \\ v_p=\frac{40}{2} \\  \\ v_p=20 \end{gathered}

c) The rms value

\begin{gathered} v_{rms}=\frac{v_p}{\sqrt{2}} \\  \\ v_{rms}=\frac{20}{\sqrt{2}} \\  \\ v_{rms}=14.14 \end{gathered}

b) Average value over alternation of the sine wave

\begin{gathered} v_{avg}=0.637v_p \\  \\ v_{avg}=0.637\times14.14 \\  \\ v_{avg}=9.0 \end{gathered}

A net force of 15 N is applied to a cart with a mass of 2.1 kg. What is the acceleration of the cart?
Shkiper50 [21]
Force = mass * acceleration
15 = 2.1 * a
a = 15/2.1 = 7.143 m/s^2

If a steady magnetic field exerts a force on a moving charge, that force is directed
lesya [120]

Answer:

C) at right angles to the direction of the motion

Explanation:

The magnetic force exerted on a charged moving particle is given by

F=qvBsin \theta

where

q is the charge of the particle

v is the velocity of the particle

B is the magnetic field intensity

\theta is the angle between the direction of v and B

Moreover, the direction of the force is perpendicular to both v and B. In particular, the direction can be found by using the right hand rule:

- index finger: direction of the velocity

- middle finger: direction of the magnetic field

- thumb: direction of the force (if the charge is positive, otherwise the direction must be reversed if the charge is negative)
