43.62m
Explanation:
Given parameters:
Energy = 8550J
Mass of bell = 20kg
Unknown:
Height of the bell = ?
Solution:
As this state, the bell possesses potential energy. Potential energy is the energy at rest in a body. It is due to the position of the body.
Potential energy = m g h
m is the mass of the body
g is the acceleration due to gravity of the body
h is the height of the body
The unknown is h and we should solve for it.
g = 9.8m/s²
Input the variables;
8550 = 20 x 9.8 x h
h = 43.62m

Answer:
4
Explanation:
Light refracts when it passes through something transparent at an angle so that eliminates the other 3.
or put differently
Light refracts whenever it travels at an angle into a substance with a different refractive index (optical density)
Answer:
A. The children will be more likely to survive than if they did not have the trait.
Explanation:
Process of elimination
B. It will not affect the children.
Cannot be true, if it didn't impact the children then how would survival of the fittest work?
D. The children will be able to adapt if the environment changes.
That just... not how adapting works when it comes to evolution.
C. The children will be more likely to survive than their parents were
Everyone has the same trait, everyone is equal in that regard.
A. The children will be more likely to survive than if they did not have the trait.
"Suppose a pair of animals has a trait that helps them survive in their environment." The trait helps them survive. Not having the trait makes them less likely to survive. A is correct
Explanation:
Organic compounds are defined as the compounds which contain carbon as their main element. For example,
is an organic compound.
Generally, organic compounds are non-polar in nature and due to the presence of covalent bonding organic compounds have low melting point.
As compound A melts at
and is soluble in water. This means it is an ionic compound as it has high melting point and it is also polar in nature.
Whereas compound B melts at
and is insoluble in water. This means that this compound has covalent bonding and it is also non-polar in nature
. Hence, it is more likely to be organic in nature.
Thus, we can conclude that compound B is more likely to be an organic
compound.
