What is the rate of acceleration of a 2,000-kilogram truck if a force of 4,200n is used to make it start moving forward?
butalik [34]

Answer:

The answer to your question is:      a = 2.1 m/s²

Explanation:

Data

Acceleration : ?

Mass = 2000 kg

Force = 4200 N

Formula

Newton's second law of motion    F = ma

                                                        a = F / m

Substitution

                                     a = 4200 N / 2000 kg

                                      a = 2.1 m/s²

Complete the mechanism for the acid-catalyzed hydrolysis of the epoxide in alcohol by adding any missing atoms, bonds, charges,
Sauron [17]

Answer:

See explanation below

Explanation:

You are missing the structure, therefore, I will do an example with one that I found on another place to try to explain.

This acid mechanism always involves carbocations, and positive charges, never negative because we are in acidic mediums.

In the first step, the lone pairs of the oxigen from the epoxide, substract one hydrogen of the reactant.

Second step, the lone pairs of the oxygen from the reactant, do a nucleophylic attack to the carbon of the epoxide. In this case, it will do it to the most substitued carbon.

Then, in the third step by acid base equilibrium, the hydrogen from the reactant that attacked, is substracted from the molecule by a molecule of water (We are in acid medium, therefore, there is traces of water) and the final structure is formed.

What is the specific heat of a 44 g piece of metal if 202 Joules of heat are required to
Ray Of Light [21]

Answer:

≈ 395,8 J/(kg * °C)

Explanation:

m = 44 g = 0,044 kg

t_{1} = 22 °C

t_{2} = 33,6 °C

Q = 202 J

The formula is: Q = c * m * (t_{2} - t_{1})

c = \frac{Q}{m * (t_{2} - t_{1} )}

Calculating:

c = 202 J / 0,044 kg * (33,6 °C - 22 °C) ≈ 395,8 J/(kg * °C)
