V125BC [204]

Answer:

Following are the solution to the given question:

Explanation:

Each method through KHP is somewhat more precise since we have weighed that requisite quantity, we exactly know the KHP intensity appropriately. Its initial 6 M HCl concentration was never considered mandatory. They have probably prepared 6 M HCl solution although long ago and could have changed its concentration over even a period.

2. Food is another concern before the trip begins. Everyone has become accustomed to a 1500 calorie diet due the food
fomenos

About 46.1 pounds of apple would be needed per day of the trip.

I managed to extract the complete scenario from the attached image.

The trip is made up of 4 men and 3 women, making a total of 7 people.

Everyone has become accustomed to 1500 calories per day.

The total calories needed per day for 7 persons = 1500 x 7

                           = 10,500 calories

189 g of apple has only 95 calories, what g of apple will produce 10,500 calories?

                 = 10,500 x 189/95 = 20,889.67 g of apple

From conversion:

1 g = 0.00220462 pounds

20,889.67 g = 20,889.67 x 0.00220462

                         = 46.1 pounds of apple

Can someone please help me with science.
Ierofanga [76]

Answer:

The tendency of an object to resist changes in its state of motion varies with mass. Mass is that quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion.
