Easy ! EVERY element and every compound melts, then boils and becomes a gas, if you heat it to a high enough temperature. That includes iron, gold, water, salt, glass, almost any substance.
Answer:
When broadcasting live on social, keep in mind that the best broadcasts are ones that feel like a conversation between brand and viewer. Unlike other forms of social video, you’ll get more views and engagement if your video
is longer and repeats key points.
Explanation:
When broadcasting live on social media, one should be live for long because in this way one can get more views as audience will increase with time. There should be an interaction with the audience like answering their questions which they write in the comments section. These comments and views will make this video to the top of news feed. Secondly the most important thing is the content of the video. One must focus on the information or knowledge he/she wants to convey and must repeat the key points again and again so that one who has missed the important points will be able catch them later.
The sound mixer will need to increase the amplitude of the sound wave produced by the singer which will increase the loudness of the sound.
<h3>Amplitude of sound wave</h3>
The amplitude of a sound wave is the maximum vertical displacement of the sound wave.
The sound mixer will need to increase the amplitude of the sound wave produced by the singer.
The increase in the amplitude of the sound wave produced by the lower tune singer will result in increased loudness of the sound.
Thus, the sound mixer will need to increase the amplitude of the sound wave produced by the singer which will increase the loudness of the sound.

Answer:
Explanation:
![\dot{m_1}= 0.5kg/s](https://tex.z-dn.net/?f=%5Cdot%7Bm_1%7D%3D%200.5kg%2Fs)
from steam tables , at 250 kPa, and at
T₁ = 80⁰C ⇒ h₁ = 335.02 kJ/kg
T₂ = 20⁰C⇒ h₂ = 83.915 kJ/kg
T₃ = 42⁰C ⇒ h₃ = 175.90 kJ/kg
we know
![\dot{m_{in}}=\dot{m_{out}}](https://tex.z-dn.net/?f=%5Cdot%7Bm_%7Bin%7D%7D%3D%5Cdot%7Bm_%7Bout%7D%7D)
![\dot{m_{1}}+\dot{m_{2}}=\dot{m_{3}}](https://tex.z-dn.net/?f=%5Cdot%7Bm_%7B1%7D%7D%2B%5Cdot%7Bm_%7B2%7D%7D%3D%5Cdot%7Bm_%7B3%7D%7D)
according to energy balance equation
![\dot{m_{in}}h_{in}=\dot{m_{out}}h_{out}](https://tex.z-dn.net/?f=%5Cdot%7Bm_%7Bin%7D%7Dh_%7Bin%7D%3D%5Cdot%7Bm_%7Bout%7D%7Dh_%7Bout%7D)
![\dot{m_{1}}h_{1}+\dot{m_{2}}h_{2}=\dot{m_{3}}h_{3}](https://tex.z-dn.net/?f=%5Cdot%7Bm_%7B1%7D%7Dh_%7B1%7D%2B%5Cdot%7Bm_%7B2%7D%7Dh_%7B2%7D%3D%5Cdot%7Bm_%7B3%7D%7Dh_%7B3%7D)
Answer:
A box sits stationary on a ramp
Explanation:
Static friction is a force which keeps an object at rest as it is in the case of the box. It has to be overcome for the object to be set into motion.
Static force of friction is calculated as follows:
F= μη
F is static force of friction.
μ is the coefficient of static friction.
η is the normal force.
