The same type of engine is placed in two different airplanes. The first airplane is twice as heavy as the second airplane
Which statement is correct about the mass of the airplane and its acceleration, assuming a constant net force? (1 point)
O Increasing the acceleration of the airplane causes the engine to provide more force.
O Decreasing the mass of the airplane will result in the airplane accelerating less.
O Increasing the acceleration of the airplane causes the engine to provide less force.
O Decreasing the mass of the airplane will result in the airplane accelerating more.

Answers

Answer 1

If the engines in both airplanes are at the same weight, the engines in both airplanes would still have the same mass because mass is constant everywhere.

What is mass?

Mass can be experimentally defined as a measure of the body's inertia, meaning the resistance to acceleration (change of velocity) when a net force is applied.

In the question, the same type of engine is placed in two different air-planes of which the first airplane is twice as heavy as the second.

We can then conclude that the correct statement about the mass of the airplane and its acceleration, assuming a constant net force is that Increasing the acceleration of the air-plane causes the engine to provide more force.

Ibuprofen can be found in 800 mg doses in over-the-counter analgesics, such as Advil and Motrin. How many grams of iburofen
does such a tablet contain?
800 mg =
g

Answers

The grams of iburofen does such a tablet contain 800 mg = 0.8g Ibuprofen

1 g = 10^-3g = .001g

Ibuprofen has 800 mg doses in over-the-counter analgesic

800g = 800 × .001

= 0.8g

Ibuprofen is Nondteriodal Anti-inflammatory Drug (NSAID)Ibuprofen's Mechanism of Action is Decreases inflammation, pain, and fever through inhibition of cyclooxygenase activity and prostaglandin synthesisnonsteroidal anti-inflammatory medication (NSAID) used for pain relief and to reduce fever by stops inflammation and by blocking formation of cyclo-oxygenase (COX-2) a chemical mediator of inflammatory chemicals. i.e prostaglandinsIt comes under the Class analgesic (reduce pain) and antipyretic (FIRE - reduce fever)e side effects of ibuprofen NSAID are peripheral edema, fluid retention with edema, tinnitus, purpura, petechiae, anorexia, diarrhea, rash, nausea, vomiting, fatigue, dizziness, lightheadedness, anxiety, confusion

What is concentration of N2O5 in the following first order reaction in which the rate is 2.4*10^-5 mole/L and rate constant is 3 * 10 ^ - 5 * S ^ - 1 ?

Answers

0.8mole/L is concentration of N2O5.

As the reaction is first order ,

so the order with respect to N2O5 is 1.

general,

Rate of equation is written as

rate = k [N2O5]^1

k is the rate constant = 3 * 10 ^ - 5 * S ^ - 1

rate = 2.4*10^-5 mole/L

N2O5 is concentration term

2.4*10^-5 mole/L = 3 * 10 ^ - 5 * S ^ - 1 [ N2O5]

N2O5 = [0.8 mole/L]

=0.8mole/L

Calculate the density in g/ml of 2.0 L of gasoline that weighs 1.32 kg

Answers

Answer: 0.66 g/mL

Explanation: The formula for density is d= m/v where m=mass and v=volume.

The mass was given in the problem, m= 1.32kg

The volume was also given in the problem, v= 2.0L

d= m/v ---> d= 1.32kg/2.0L ---> d=0.66kg/L

The problem calls for the answer to be written in g/mL, so we must convert the units. 1 kg contains 1000g and 1 L contains 1000 mL.

1000g/1000mL = 1 so the units change but the 0.66 does not. Therefore, your answer is 0.66g/mL (Two significant figures because 2.0 only has 2 significant figures).

Paulo is experimenting with H2O in its different states. He would like to present all the information he collected in one place. He thinks he should use a phase change diagram, but he isn't sure. What information could you give Paulo to encourage him to use a phase change diagram?

Answers

Paulo needs to use a phase diagram to show how much stable each of the various phases of water is.

What is the phase diagram?

The phase diagram could be used to obtain the changes in a substance at different phases of matter. We know that water could exist as solid, liquid or gas. The state in which the water is a function of the pressure and the temperature of the system.

The phase diagram could be used to see the various conditions of temperature and pressure where we can trace to the liquid, solid and gaseous phases of the substance that is under study. On this phase diagram, we can also locate the triple point of water.

Given that the pressure and the temperature changes of water could be shown on a phase diagram, it then follows that Paulo needs to use a phase diagram to show the various phases of water.

The concentration of the urine is determined as 1.002 g/ml.

What is concentration?

The concentration of a chemical substance expresses the amount of a substance present in a mixture.

What is the urine concentration?

The concentration of the urine is determined from the ratio of mass to volume of the urine or density of the urine.

Urine Concentration = mass / volume

Urine concentration = 4 .007 g / 4 ml

Urine concentration = 1.002 g/ml
