Which is an example of a covalent compound having high melting point?
Which is an example of a covalent compound having high melting point? These covalent bonds are very strong. They also tend to be very hard with high melting points which are different from most of the covalent compounds. The example of this kind of covalent compounds includes diamond and graphite of carbon atom network. They […]

When your diaphragm and intercostal muscles are relaxing What are you doing?
When your diaphragm and intercostal muscles are relaxing What are you doing? When you exhale: the external intercostal muscles relax and the internal intercostal muscles contract, pulling the ribcage downwards and inwards. the diaphragm relaxes, moving back upwards. lung volume decreases and the air pressure inside increases. What happens in the lungs when the diaphragm […]
What is the minimum speed the roller coaster must have to complete the loop?
What happens when the slope of the line is negative?
What happens when the slope of the line is negative? A negative slope means that two variables are negatively related; that is, when x increases, y decreases, and when x decreases, y increases. Graphically, a negative slope means that as the line on the line graph moves from left to right, the line falls. What […]

Can something be so loud it kills you?
Can something be so loud it kills you? Acoustic grenades can go roughly from 120 decibels to 190 decibels. German researcher Jurgen Altmann showed that a blast of 210 decibels or more affects the inner organs — the lungs — and could cause internal injury that could lead to death. A blast will impact the […]
