Answer:

Explanation:

Precipitation is defined as the creation of a solid from a solution. When the reaction occurs in a liquid solution, the solid formed is called the 'precipitate'. The chemical that causes the solid to form is called the 'precipitant'.

At TTT = 14 ∘C∘C, how long must an open organ pipe be to have a fundamental frequency of 262 HzHz ? The speed of sound in air is

Stolb23 [73]

Answer:

Length of pipe organ(L) = 0647 m (Approx)

Explanation:

Given:

Temperature (T) = 14°C

Fundamental frequency (F) = 262 Hz

Speed of sound (v) = 331 + 0.60(T) m/s

Find:

Length of pipe organ(L)

Computation:

Speed of sound (v) = 331 + 0.60(14) m/s

Speed of sound (v) = 339.4

Length of pipe organ(L) = Speed of sound (v) / 2(Fundamental frequency)

Length of pipe organ(L) = 339.4 / 2 (262)

Length of pipe organ(L) = 0647 m (Approx)

An asteroid has acquired a net negative charge of 126C from being bombarded by the solar wind over the years, and is currently i

Lemur [1.5K]

The net charge of the asteroid is
$Q=-126 C$
with a negative sign since it is a net negative charge.

The charge of one electron is
$e=-1.6 \cdot 10^{-19} C$

In order to find what is the excess of electrons on the asteroid, we must simply divide the net charge in excess on the asteroid by the charge of a single electron, and we find:
$N= \frac{Q}{e}= \frac{-126 C}{-1.6 \cdot 10^{-19} C} =7.87 \cdot 10^{20}$
