Answer:

Explained below.

Explanation:

In electric heaters, the wire used is nichrome wires and it can resist oxidation. Whereas, in electric bulbs, wires used are called tungsten and they undergo Oxidation begins at high temperatures between 500°C and 1200°C. Therefore, we would can't interchange because tungsten wires need a protective film/inert gas to withstand the high temperatures so that the wires don't get weak and break.

a student solving for the acceleration of an object has applied appropriate physics principles and obtained the expression a

kozerog [31]

Given:

$Force, f = 12 \frac{kg-m}{sec^{2} }$

$Mass, m = 7 kg$

$Acceleration, a_{1} = 3\;\frac{m}{sec^{2} }$

$a = a_{1}+\frac{f}{m}$

$Substitute\;the\;values\;of\;f,\;m\;and\;a_{1}\;in\;the\;above\;equation,$

$a = 3+\frac{12}{7}$

$a = 3 + 1.714$

Therefore, the acceleration is,

$a = 4.714\;\frac{m}{sec^{2} }$

<h3>Explain Acceleration?</h3>

An object's rate of changing its velocity is known as its acceleration, which is a vector quantity. If an object's velocity is changing, it is accelerating. When anything moves faster or slower in a straight line, it is said to have been accelerated. Even if the speed is constant, motion on a circle accelerates because the direction is always shifting.

Which rope would have the longest wavelength-one with a frequency of 2 hz or one with a frequency of 3 hz?

Elis [28]

The frequency f is related to the wavelength $\lambda$ by the equation
$\lambda = \frac{v}{f}$
where v is the speed of the wave in the rope.

We can see from the formula that, if v is kept constant, smaller frequency means larger wavelength. So, the rope with frequency 2 Hz will have the longest wavelength.

14 km = m on conversions using a ladder method

lozanna [386]

Using the metric units kilometer (km) and meter (m), as seen in the picture of the ladder method example. So, the answer would be 14km = 14000m

A wave moving with a speed of 3.0 m/s has a frequency of 9 Hz. What is the wavelength of the wave?

Dovator [93]

From the question, we are told that:
Wave speed, V = 3.0 m/s
Wave frequency, F = 9 Hz.
The formula for calculating wavelength = V /F
Wavelength = 3 / 9 = 0.33 m.
The correct option is A.
