Answer:

<h2>69,480 kg.m/s</h2>

Explanation:

The momentum of an object can be found by using the formula

momentum = mass × velocity

From the question we have

momentum = 45 × 1544

We have the final answer as

<h3>69,480 kg.m/s</h3>

Why do different substances heat up and cool down at different rates?
shepuryov [24]
Each substance has its own unique structure and properties that are based on these structures.

One of those most important properties is the "specific heat" value.
Specific heat is defined as the amount of heat required to raise the temperature of a unit mass of a substance by 1 degree Celsius.

Each substance has its own specific heat. The higher the specific heat of a substance, the longer it will take to heat up or cool down.

Hope this helps :)

An extremely soluble salt is added to water, and all of it dissolves. Is it at equilibrium? Explain.
alexdok [17]
Once the substance stops dissolving, the system is at equlibrium with the water and the undissolved salt now, if it is in the process of dissolving because it is completely soluble but has not been able to completely dissolve, it is not at equilibrium

Calcium carbonate interacts with omadacycline (Nuzyra). How should this interaction be avoided?(Interactions) hint look up omada
stellarik [79]

Answer: An interaction is caused between the two medications (Calcium carbonate and Omadacycline) and causes serious negative side effects, due to the fact that when the two are taken together the body is unable to process the antibiotic therefore causing a reduction in the concentration of antiobiotics in the blood stream. this causes a reduction the body's ability to fight off the infection. In addition, drug interactions with calcium increase the risk of dangerously high calcium levels in the blood and disrupt the body´s basal state.

Explanation:

Omadacycline is a broad spectrum antibiotic. It belongs to the tetracycline group and specifically to the aminomethylcycline subclass and is used mainly in the treatment of  treatment of community-acquired bacterial pneumonia and acute skin and skin structure infections. the mecanism of action of Omadacycline works like every other tetracycline antiobiotic. It inhibits the bacterial protein synthesis thereby rendurig the bacteria useless and thus stopping the replicaton of these bacterias.

Calcium carbonate on the other hand, is usuallly administered as a dietary supplement when the corporal levels of calcium do not reach sufficient levels.  It may also be used as an antacid to relieve heartburn, acid indigestion, and nausea. It is available with or without a prescription and is available in many forms for example;  as a tablet, chewable tablet, capsule or as a liquid.

Calcium is vital for healthy bones, muscles, nervous system, and heart. Calcium is involved in cardiac muscle contraction and electrical impulse conduction.

When calcium carbonate is taken with Omadacycline causes a significant increase in the levels of calcium in the blood. Excess levels of calcium interfere with the absorption of the antibiotic  because calcium binds to the tetracycline in the intestine causing a reduction in the efectiveness. Failure to control the infection could lead to severe side effects whether temporary or permanent and in extreme cases death.

<h3>Calcium carbonate SHOULD NOT BE TAKEN WITH </h3>
  • Bisphosphonates
  • Fluoroquinolone antibiotics
  • H2 blockers
  • Proton pump inhibitors (PPIs)
  • Tetracycline antiobiotics (Omadacycline- Nuzyra)
  • Thiazide diuretics

In conclusion, calcium carbonate should not be taken with tetracycline antiobiotics in this case Omadacycline because it causes an ncrease in calcium levels which binds to the antibiotic therefore reducing its absorption by the intestine and reducing its effect in fighting off the infection. The antiobiotic should be taken two hours before the calcium carbonate or about four to six hours after.
