The net force on a vehicle that is accelerating at a rate of 1.2 m/s² is 1500 newtons. What is the mass

kotegsom [21]

Answer:

1250kg

Explanation:

Given parameters:

Acceleration = 1.2m/s²

Force = 1500N

Unknown:

Mass on the vehicle = ?

Solution:

According to newton's second law of motion:

Force = mass x acceleration

Since mass is the unknown, insert the parameters and solve;

1500 = mass x 1.2

mass = $\frac{1500}{1.2}$ = 1250kg

at a particulat temperature, a smaple of pure water has a Kw of 7.7x10-14. what is the hydroxide concentration of this sample

ycow [4]

Answer: The hydroxide concentration of this sample is $3.85\times 10^{-7}$

Explanation:

When an expression is formed by taking the product of concentration of ions raised to the power of their stoichiometric coefficients in the solution of a salt is known as ionic product.

The ionic product for water is written as:

$K_w=[H^+]\times [OH^-]$

$7.7\times 10^{-14}=[H^+]\times [OH^-]$

As $[H^+]=[OH^-]$

$2[OH^-]=7.7\times 10^{-14}$

$[OH^-]=3.85\times 10^{-7}$

Thus hydroxide concentration of this sample is $3.85\times 10^{-7}$
