Is metal sustainable?

User Avatar

Asked by Wiki User

Metal can be sustainable when extracted and processed using environmentally-friendly methods, such as recycling. However, the mining and production of primary metals can have negative impacts on the environment and ecosystems. Recycling metal reduces the need for primary metal extraction and helps conserve natural resources.

How does an old seismograph work?

User Avatar

Asked by Wiki User

An old seismograph consists of a heavy mass attached to a pendulum that remains stationary during an earthquake while the ground moves. The movement of the ground causes the rest of the seismograph to move, but the stationary mass records this movement on a rotating drum, providing a visual record of the earthquake's intensity and duration.

The insulator keeps the electricity inside the wire and?

User Avatar

Asked by Wiki User

prevents it from escaping into the surrounding environment. Insulators are materials with high resistance to electrical current, helping to maintain the flow of electricity along the intended path. Without insulators, there would be a risk of electric shock or short circuits.

What some things which use light?

Asked by Wiki User

Some things that use light include light bulbs for illumination, cameras for capturing images, solar panels for generating electricity, and optical fibers for telecommunications.

Why doesn't ceramic conduct electricity?

User Avatar

Asked by Wiki User

Ceramic materials are typically non-conductive because their atomic structure does not allow for the easy movement of electrons. This means that electrons cannot flow through the material to create an electrical current. Additionally, ceramics are usually insulators with high resistivity, further inhibiting electrical conduction.

What is the strongest natural fiber?

User Avatar

Asked by Wiki User

Spider silk is widely considered to be the strongest natural fiber. It has a tensile strength that is comparable to steel, yet it is lightweight and flexible.

Does lighter objects have mor or less inertia then heavier objects?

User Avatar

Asked by Wiki User

Lighter objects typically have less inertia than heavier objects. Inertia is the tendency of an object to resist changes in its motion, and the amount of inertia an object has is directly related to its mass. Heavier objects have more mass and therefore more inertia compared to lighter objects.

Is compression a drag force?

User Avatar

Asked by Wiki User

No, compression is not a drag force. Compression refers to the reduction in size or volume of a substance due to external pressure, while drag force is a resistive force that opposes an object's motion through a fluid.

How many mAh does a 9.6v have?

User Avatar

Asked by Wiki User

To calculate the mAh capacity, we need to know the current rating of the battery as well. The mAh (milliampere-hour) capacity is a measure of how much charge a battery can hold over time. It is not determined solely by the voltage (9.6V in this case) but also by the current rating of the battery.

Why are blobs big?

User Avatar

Asked by Wiki User

Blobs appear big due to their amorphous and shapeless structure, which lacks defined boundaries or edges. Their size can vary depending on the amount of material they contain or the environment they are in. Blobs are often depicted as large to emphasize their formless and ever-changing nature.

Why does a battery supply direct current?

User Avatar

Asked by Wiki User

A battery supplies direct current (DC) because it produces a constant flow of electrons in one direction within the circuit. This is achieved through a chemical reaction that establishes a potential difference. In contrast, alternating current (AC) changes direction periodically, making it more suitable for long-distance power transmission.

What is a small angled surface formed between two surfaces?

User Avatar

Asked by Wiki User

A small angled surface formed between two surfaces is called a chamfer. Chamfers are typically created to ease sharp edges or remove burrs, and they can also provide a finished appearance to a part or product.

What does pewter the metal feel like?

User Avatar

Asked by Wiki User

Pewter is a soft metal with a smooth and slightly dull texture. It is cool to the touch and has a weighty feel compared to other metals like aluminum. Its surface may develop a slight patina over time, adding to its unique look and feel.

Which was the first thing to electricity?

Asked by MickeyMousee

The first thing to use electricity was the electric light bulb, invented by Thomas Edison in 1879.

Why do smoke detectors beep at night?

User Avatar

Asked by Wiki User

Smoke detectors may beep at night for several reasons, such as low battery power, dust or debris blocking the sensor, or high humidity causing condensation. It is important to investigate the cause of the beeping to ensure the smoke detector is functioning properly and to address any potential safety hazards.

What are benefits of raw materials?

User Avatar

Asked by Icelscorpion25

Raw materials are essential for manufacturing products and goods. Using raw materials allows for customization, quality control, and cost-effectiveness in production processes. Additionally, sourcing raw materials locally can reduce transportation costs and support local economies.

What process is used to make visine?

User Avatar

Asked by Wiki User

Visine is made through a manufacturing process that involves combining ingredients such as active ingredients, preservatives, and stabilizers in a specific formulation. This formulation is then mixed, tested, and packaged in sterile conditions to ensure safety and efficacy. The final product is then distributed for sale.

Can you increase the force and direction?

User Avatar

Asked by Wiki User

To increase force, you can exert more physical effort or use mechanical advantage like a lever or pulley system. To change direction, adjust the angle or orientation of the force to push, pull, or lift in a different way. Always ensure proper technique and safety measures when modifying force and direction.

Electroplating plastic abs?

User Avatar

Asked by Wiki User

Electroplating on ABS plastic involves using a conductive coating to make the plastic surface receptive to the electroplating process. This conductive coating is typically a layer of nickel or copper that is applied to the ABS surface before electroplating with the desired metal finish, such as chrome or gold. Proper preparation and adhesion of the conductive layer are crucial for achieving a durable and high-quality electroplated finish on ABS plastic.

Explain x-t v-t graphs?

User Avatar

Asked by Kashiviswanath

An x-t (position-time) graph shows how an object's position changes over time, while a v-t (velocity-time) graph shows how an object's velocity changes over time. In an x-t graph, the slope represents the object's velocity at that point, while in a v-t graph, the area under the curve represents the object's displacement.
