Very high melting<span> points - Substances with giant covalent structures have very high</span>melting<span> points, because a lot of strong covalent bonds must be broken. Graphite, for example, has a </span>melting point<span> of more than 3,600ºC. Variable conductivity - Diamond does not conduct electricity.</span>
Answer:
5s
Explanation:
-A period is the time it takes to make one full back-and-forth swing.
-A period is calculated as the time taken for a complete swing divided by one cycle:
Hence, the period of the pendulum is 5s
Answer:
Horizontal distance from the foot of the cliff is 40 m
Explanation:
Given :
Speed of stone 
Vertical distance 
m
Gravitational acceleration 
From the kinematics equation,
Where 
initial velocity ( 
)
So time take to fall down,
sec
Now find horizontal distance travel by stone,
m
Therefore, the horizontal distance travel by stone is 40 m
Answer:
The procedure involves severing the corpus callosum, the main bond between the brain's left and right hemispheres. ... This impairment can result in split-brain syndrome, a condition where the separation of the hemispheres affects behavior and agency.
Explanation:
Answer: There is no change in temperature when heat is given out or taken in by the object
Explanation:
The heat capacity of an object is infinite when it undergoing phase transition since the heat is ued in changing the state of the substance and ntot in raising the teperature of the substiance. Thus, heat capacity is infinite during change of state. This is known as latent heat. The correct option is
There is no change in temperature when heat is given out or taken in by the object
