a. t=0.553 s
b. vox(horizontal speed) = 3.62 m/s
<h3>Further explanation</h3>Given
h = 1.5 m
x = 2 m
Required
a. time
b. vo=initial speed
Solution
Free fall motion
a. h = 1/2 gt²(vertical motion=h=voyt+1/2gt²⇒voy = 0)
t = √2h/g
t = √2.1.5/9.8
t=0.553 s
b. x=vox.t(horizontal motion)
vox=x/t
vox=2/0.553
vox=3.62 m/s
Answer: Option (d) is the correct answer.
Explanation:
An equation in which electrolytes are represented in the form of ions is known as an ionic equation.
Strong electrolytes easily dissociate into their corresponding ions. Hence, they form ionic equation.
is a strong acid and
is a strong bases, therefore, both of them will dissociate into ions.
Thus, total ionic equation will be as follows.
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.
