The quantum mechanical model of the atom ____. a. defines the exact path of an electron around the nucleus b. was proposed by Niels Bohr c. involves finding an electron somewhere in a specific orbital d. has many analogies in the visible world
Answers
Answer:
Quantum mechanical model = involves finding an electron somewhere in a specific orbital.
Explanation:
The quantum mechanical model of an atom involves finding an electron somewhere in a specific orbital. This method is completely based on mathematical calculations. It defines the probability of finding an electron rather than its reality.
These are designated by some letters like s, p, d, f...... and the corresponding energy levels are 1st, 2nd, 3rd and so on.....
So, the correct option is (c) "involves finding an electron somewhere in a specific orbital".

Answer:
40g
Explanation:
Mass = density x volume
= 2 x 20
= 40g
Answer:
m = V × ρ
= 20 milliliter × 2 gram/cubic meter
= 2.0E-5 cubic meter × 2 gram/cubic meter
= 4.0E-5 gram
= 4.0E-8 kilogram
Explanation:
The density of a material, typically denoted using the Greek symbol ρ, is defined as its mass per unit volume.
ρ =
m
V
where:
ρ is the density
m is the mass
V is the volume
The calculation of density is quite straightforward. However, it is important to pay special attention to the units used for density calculations. There are many different ways to express density, and not using or converting into the proper units will result in an incorrect value. It is useful to carefully write out whatever values are being worked with, including units, and perform dimensional analysis to ensure that the final result has units of mass volume. Note that density is also affected by pressure and temperature.

Let's use Newton's 2nd law of motion:
Force = (mass) x (acceleration)
Force = (68 kg) x (1.2 m/s²) = 81.6 newtons .
68*1.2=81.6

Answer:
1/2
Explanation:
This will lead us to simultaneous equation since there are two person involved doing the same job each day.
For Ted;
Since Ted can wax 8 cars or wash 10 cars in a day. Mathematically, we have
8x + 10w = 1... (1)
Where x is for waxing cars, w is for washing cars
Similarly for Tom,
Tom can wax 3 cars or wash 5 cars in a day as well, this gives us;
3x + 5w = 1... (2)
Equating 1 and 2, we have;
8x + 10w = 1... (1)
3x + 5w = 1... (2)
Using elimination method, we will multiply eqn 1 by 3 and eqn 2 by 8 to have;
24x + 30w = 3
24x + 40w = 8
Subtracting eqn 4 from 5 we have;
30w - 40w = 3 - 8
-10w = -5
w = 5/10
w = 1/2
Therefore each man's opportunity cost of washing a car is 1/2
