Four forces are exerted on each of the two objects shown below:

zzz [600]

Answer:

A: Object A will move in the up direction. But not object B

Explanation:

It will move in the up direction because object A has an unbalanced force. For the up direction there, it is 6 newtons and for the bottom direction, it is 2 newtons. For the right and left direction, both of them are 3 newtons. So object A will move in the up direction because it has the most newtons(which is 6).

For Object B, it is unbalanced too. But object B will move to the right because it is 2 newtons there and there is one newton on the left. Furthermore, the up and down directions are 3 newtons. So they are balanced and will cancel out. Therefore, object A will move in the right direction because it has the most newtons(which is 3).

So the final answer is object A. Hope it helped!

If the principal quantum number is n = 3, what are the name(s) of the subshells?

Ede4ka [16]

The name(s) of the subshells are s,p and d

<h3>Further explanation</h3>

Each orbital in an atom consists of 4 quantum numbers

n is the principal quantum number.

l is the angular momentum / azimuthal quantum number

ml, the magnetic quantum number

ms, the electron-spin quantum number

Value of n: positive integer

value of l: s = 0, p = 1, d = 2, f = 3 , ..(n-1)

ml value: between -l to + l

ms value: +1/2 or -1/2

n=3, then the possible value of l is a maximum of n-1 = 3-1 = 2

So the value of subshells = 0,1 and 2

The diagram below shows three kettles with their powers and the time they take to boil 500cm3 of water. How much energy is trans

Bad White [126]

The energy transferred is given as the product of power and time. The 1.4 kW kettle with boiled water produces 378 kJ of energy.

<h3>What is energy?</h3>

Energy is the quantitative property that determines the work done by the body in the form of heat and light.

The image showing the kettles with time and power is attached below.

Given,

Power of the kettle = 1.4 kW

Time taken = 4.5 minutes

If power = energy ÷ time

Then, energy = power × time

= 1.4 × 0.075

= 0.105 KWh

Therefore, 0.105 kWh or 378KJ is the energy transferred.

6 Calculate the number of molecules in 8 g of oxygen.

Mariana [72]

Answer:

If you mean the number of atoms in 8g of oxygen, it's 3.011 x 10^23 atoms.

Explanation:

Convert the grams to moles. 8 grams of oxygen is 0.5 moles. Then multiply the number of moles by Avogadro's number: 6.022 x 10^23.
