Answer:

121.11m/s²

Explanation:

Given parameters:

Force = 525N

Mass = 4.5kg

Unknown:

Acceleration = ?

Solution:

From Newton's second law of motion, we can find the solution to this problem. Using the expression below:

F = m x a

F is the force

m is the mass

a is the acceleration

So'

525 = 4.5 x acceleration

Acceleration = 121.11m/s²

Sierra has a special kind of liquid rubber. She knows that ultraviolet light is

lana66690 [7]

Answer:

See explanation

Explanation:

Light is a form of energy. Both ultraviolet light and xrays are part of the electromagnetic spectrum.

As was said in the question, ultraviolet rays is absorbed by the rubber. We must know that prolonged exposure of this piece of rubber to incident ultraviolet light causes the vaporization of volatile materials in the rubber.

When volatile materials in the rubber vaporize, the rubber can become solid. Thus, ultraviolet light can cause rubber to become solid.

However, not all types of light can do this hence it does matter the type of light that falls on the rubber material.

Which of the following statements best explains the observation that hydrogen fluoride has the highest boiling point of all the

olasank [31]

Answer:

c. HF can participate in hydrogen bonding.

Explanation:

The boiling points of substances often reflect the strength of the intermolecular forces operating among the molecules.

If it takes more energy to separate molecules of HF than of the rest of the hydrogen halides because HF molecules are held together by stronger intermolecular forces, then the boiling point of HF will be higher than that of all the hydrogen halides.

A particularly strong type of intermolecular attraction is called the hydrogen bond, which is a special type of dipole-dipole interaction between the hydrogen atom in a polar bond, such as N-H, O-H, or F-H, and an electronegative O, N, or F atom.

Calculate the mass of water produced when 7.26 g of butane reacts with excess oxygen

MaRussiya [10]

Answer:

11.3 g.

Explanation:

Hello there!

In this case, since the combustion of butane is:

$C_4H_{10}+\frac{13}{2} O_2\rightarrow 4CO_2+5H_2O$

Thus, since there is a 1:5 mole ratio between butane and water, we obtain the following mass of water:

$m_{H_2O}=7.26gC_4H_{10}*\frac{1molC_4H_{10}}{58.14gC_4H_{10}}*\frac{5molH_2O}{1molC_4H_{10}} *\frac{18.02gH_2O}{1molH_2O}$

Therefore, the resulting mass of water is:

$m_{H_2O}=11.3gH_2O$

Best regards!
