The spped is: 
v=d/t
or, v=3000m/100s
or, v= 30m/s

the velocity is not constant as the roller coaster keeps changing direction, it is not constant

Name four main Homologous series in organic chemistry...... plz hlp me
Akimi4 [234]
I believe the four series you are looking for are straight-chain alkanes, alkenes, and alkynes, and cycloalkanes. These all have the same repeating of CH2 as the base group, while alkenes have a double bond somewhere in the molecule, and alkynes a triple somewhere.

When dissolved in water, a neutral molecule of calcium chloride dissociates into three ions - one calcium ion and two chloride i
Mashcka [7]

Explanation:

Calcium chloride is an ionic compound as it is formed by transfer of an electron to each chlorine atom.

So, being an ionic compound calcium chloride is able to dissociate completely into water.

Hence, the dissociation reaction will be as follows.

         CaCl_{2}(s) \rightarrow Ca^{2+}(aq) + 2Cl^{-}(aq)

Since, two electrons has been lost by single calcium atom. Therefore, calcium atom will have a charge of +2.

Thus, we can conclude that the charge on the calcium ion, in elementary units is +2.

Science lab questions:
Ede4ka [16]

Answer:

glucose and galactose

concentration of the enzyme

temperature and pH

glucose and galactose

Explanation:

Enzymes are biological catalysts. They catalyze various biochemical reactions in the  body. Enzymes are proteins.

The enzyme responsible for the breakdown of lactose is lactase. This enzyme catalyzes the breakdown of lactose to glucose and galactose. Galactose is about 65% as sweet as sucrose.

The rate of enzyme reaction is influenced by the concentration of the enzyme.  As the concentration of the enzyme is increased, the velocity of the reaction proportionately increases.

Temperature and pH are important environmental factors that affect the rate of enzyme catalyzed reaction because they influence the activity of the enzyme and may even denature the enzyme.
