<h3>What is the property of metals?</h3>

We know that the properties of metals can be used to identify an unknown substances as a metal. We know that metals are able to react with acids to liberate the metal salt and hydrogen gas. Metals do not react with bases because they can not accept electrons.

Metalloids are generally amphoteric in nature. They can react with both the acid and the basses to form compounds. The nonmetals do not react with acid or base.

Looking at the result, we are told that the entry in the second row have the entries  nothing, nothing, nothing. If this is the outcome, then it follows that the element should be placed in the column for metalloids.

What is the frequency of the sinusoidal graph?
Arisa [49]

Answer:

For finding frequency, we need to first find the period of the graph.

The period of a sinusoidal graph is the time interval in which it repeats its pattern.

In the graph, we can see, after 1/period time, it repeats its pattern.

Hence the period of the graph is  \pi /2.

Now we need to find its frequency 1/\pi /2

The formula for frequency is 2/\pi

This is the answer

i hope you pass the assignment

try your best!

1.0 x 10^2 m what is the frequency of the waves
MAVERICK [17]

Answer:

f = 3 × 10⁶ Hz

Explanation:

Given data:

Wavelength of wave = 1.0 ×10² m

Frequency = ?

Solution:

Formula:

Speed of light = wavelength× frequency

Frequency = speed of light / wavelength

speed of light = 3× 10⁸ m/s

f = 3× 10⁸ m/s / 1.0 ×10² m

f = 3 × 10⁶ s⁻¹

s⁻¹ = Hz

f = 3 × 10⁶ Hz
