How is a shower plumbed?

How is a shower plumbed? The water supply for a shower arrives via two pipes: hot and cold. In construction that is less than 30 years old, these pipes are usually copper. The pipes connect to a shower valve that controls the temperature and flow of water to the shower head. What is needed for […]

Can you cut conduit with a hacksaw?

Can you cut conduit with a hacksaw? Rigid pipe can be cut with such PVC pipe and tube cutters as hacksaws, power miter saws and scissor-type cutters, but ratchet-style cutters tend to strike an effective balance of affordability, flexibility and ease of use. With a hacksaw, slowly draw the blade back and forth, making sure […]

Why angular momentum of Earth is conserved?

Why angular momentum of Earth is conserved? Earth moves under the influence of the gravitational forces of all bodies in the Solar System. The energy and angular momentum of Earth are conserved, because the gravitational force is both conservative and central. Is angular momentum is a scalar? Angular momentum is a vector quantity that represents […]

How do you find the missing resistance?

How do you find the missing resistance? If you know the circuit’s total current and voltage, you can use Ohm’s Law R = V/I to find the total resistance, then the formula for resistors in parallel to solve for the missing resistor value. What happens when resistors are connected in parallel? When resistors are connected […]
