Answer:
1. Distance travelled = 12 km.
2. Displacement = 8.6 km
Explanation:
From the question given above, the following data were obtained:
Distance 1 (d₁) = 7 km
Distance 2 (d₂) = 5 km
Total distance =?
Displacement =?
1. Determination of the distance travelled.
Distance 1 (d₁) = 7 km
Distance 2 (d₂) = 5 km
Total distance (dₜ) =?
dₜ = d₁ + d₂
dₜ = 7 + 5
dₜ = 12 km
2. Determination of the displacement.
In the attached photo, R is the displacement.
We can obtain the value of R by using the pythagoras theory as illustrated below:
R² = 7² + 5²
R² = 49 + 25
R² = 74
Take the square root of both side
R = √74
R = 8.6 km
<u>series </u>
current same to all resistors
p.d is divided to each resistors depending on their resistivity
V = IR the resistor which have more resistance (also resistivity) gain more p.d
<u>parallel
</u> p.d is same to all components
<u /> current is divided to each resistor depending on their resistivity
I = V/R more current flows through one with less resistance (also resistivity)
here as it is series connection,<u>current is same</u> to all resistors irrespective of their resistance
Answer:
So the force of attraction between the two objects is 3.3365*10^-6
Explanation:
m1=10kg
m2=50kg
d=10cm=0.1m
G=6.673*10^-11Nm^2kg^2
We have to find the force of attraction between them
F=Gm1m2/d^2
F=6.673*10^-11*10*50/0.1^2
F=3.3365*10^-8/0.01
F=3.3365*10^-6
The potential energy would be holding the yo-yo as the kinetic would be throwing it down and getting it back up
Answer:
(1)
(2)
but 
transition not allowed.
Explanation:
Atoms can be described by the quantum number n, spin quantum number S, angular momentum quantum number L, and total angular momentum quantum number J. Based on approximation Russel- Saunders electron coupling, the atomic term symbol can be written as 
.
The conditions or selection rule to promoting the electron are discussed below:
(1) The total spin should not change that is .
(2) The total angular momentum change should be, but transition not allowed.
