Answer:

v = 300 mph due South.

Explanation:

Given that,

The Princess cruise ship left San Francisco and traveled south for 8 hours at a speed of 30mph.

We need to find the velocity of the ship. It can be calculated by total distance divided by total time taken.

Velocity is a vector quantity i.e. it has both magnitude and direction. On the other hand, the speed has only magnitude (scalar quantity).

In this case it is mentioned that the cruise is travelling south with a speed of 300 mph.

Hence, the velocity is 300 mph in South direction.

The density of a gold nugget is 19.3 g/cm3. If the volume of the gold nugget is 0.00369 L the mass of the nugget is
Sauron [17]

Answer:

The answer to your question is 71.22 g

Explanation:

Data

Density = 19.3 g/cm³

Volume = 0.00369

mass = ?

Formula

Density = \frac{mass}{volume}

Solve for mass

mass = density x volume

Process

1.- Convert volume from liters to cubic centimeters

                 1 l ----------------  1000 cm³

             0.00369l ---------   x

                x = (0.00369 x 1000 ) / 1

                x = 3.69 cm³

2.- Substitution

       mass = 19.3 x 3.69

3.- Simplification and result

       mass = 71.22 g

An electron in an atom is known to be in a state with magnetic quantum number ml=−1
Ulleksa [173]

Explanation:

It is known that the maximum value of ml is equal to the vale of l. But the minimum value of n is as follows.

                    n = l + 1

where,     n = principle quantum number

                l = azimuthal quantum number

Values of n can be 1, 2, 3, 4 and so on. Whereas the values of l can be 0, 1, 2, 3, and so on.

Also, "m" is known as magnetic quantum number whose values can be equal to -l and +l.

So, when n = 1 then l = 0 and m = 0.

When n = 2 then l = 1 and values of m will be equal to -1, 0, +1. As it is given that the magnetic quantum number ml = -1. Hence, it is only possible when n = 2.

Thus, we can conclude that the smallest possible value of the principal quantum number n of the state is 2.

A sample has a volume of 10 ml and a mass of 4.2 g what density of the object
Agata [3.3K]

Answer:

0.42g/cm³ or 420kg/m³

Explanation:

1cm³ = 1ml

10 × 1cm³ = 10cm³

Density = Mass ÷ Volume

4.2g ÷ 10cm = 0.42 g/cm³

Density = 0.42g/cm³ or 420kg/m³

A physical property is:a) a property the sample displays that results in a change in composition. b) the ability of a sample to
ladessa [460]

Answer: Option (d) is the correct answer.

Explanation:

Properties that are unable to bring any change in chemical composition of a substance are known as physical properties.

For example, size, shape, volume, density, boiling point, melting point etc is a physical property.  

Whereas properties that bring change in chemical composition of a substance are known as chemical properties.

For example, combustion, toxicity, reactivity etc are all chemical properties.

Thus, we can conclude that a physical property is a property the sample displays without changing its composition.
