Answer: B. Nodes

Explanation:

Standing waves (so called because they seem to be immobile) occur when two waves interfere with the same frequency, amplitude but with different direction, along a line with a phase difference of half wavelength.

In these waves there are two types of points:

The nodes, which are points that remain motionless or stationary and do not vibrate. They are due to the destructive interference of both waves when they meet.

The antinodes, which are points that vibrate with a maximum vibration amplitude. They are due to the non-destructive interference of both waves.

If you connected 10 of these 12V (10 W) lamps in parallel, to the 12V source, how much current would the source have to supply

Flauer [41]

Answer:

$T=8.33A$

Explanation:

From the question we are told that:

Number of battery $n=10$

Voltage source $E=12V$

Lamp Power $P=10W$

Generally the equation for Resistance is mathematically given by

$R=\frac{V^2}{P}$

$R=\frac{12^2}{10}$

$R=14.4ohms$

Therefore

$R_{eq}=\frac{14.4}{10}$

$R_{eq}=1.44$

Generally the equation for Current is mathematically given by

$T=\ffrac{V}{Req}$

$T=\frac{12}{1.44}$

$T=8.33A$

What s physics?

Alex777 [14]

The answer is (B. The study of Matter and Energy) but technically you could consider physics all of these as engineering is based on physics and that would be the study of inventions, chemistry and biology were both discovered because of physics, and physics invokes more math than any other subject as it applies math to the entire Universe.

Formed through longshore drift a. sea stack b. sandbar c. spit d. headland

ANTONII [103]

<h3>Answer;</h3>

Sand Spit or Spit

<h3>Explanation;</h3>

Long shore drift is the process that occurs when a sheet of water moves on and off the beach, in other words the swash and back swash, thus capturing and transporting sediment on the beach back out to the sea.
Sandbar is normally formed when the sandspit stretches across a bay and connects the two sides. Headland is a high piece of land that extends out onto the sea. Sea stacks on the other hand results from the collapsing of the roof of the arch.
