Example of weathering and erosion:
- The ocean beating up against the cliff of a wall and slowly wearing away rock
- A river flowing through river banks and the bank slowly stretching apart further and further as time goes on
- Water freezes in a crack on a rock. As the water freezes, the crack expands on the rock.
- A plant is planted in the same spot every year and slowly breaks up the soil.
- Acid rain slowly breaks down the structure of a building.
Answer:
0.65 A.
Explanation:
Given:
Pmax = 10 W
R = 23.9 Ω
Formula for calculating power,
P = I × V
= I^2 × R
I^2 = 10/23.9
I = 0.65 A.
Answer:
Magnetic quantum number.
Explanation:
Orbitals with the same principal quantum number and the same l value belong to the same subshell.
The magnetic quantum number, ml distinguishes the orbitals available within a subshell, and is used to calculate the azimuthal component of the orientation of space.
The value of ml can range from -ℓ to +ℓ. The s, p, d, and f subshells contain 1, 3, 5, and 7 orbitals each, with values of m within the ranges 0, ±1, ±2, ±3 respectively while containing 2 different spin electrons.
Answer:
Acceleration is rate of change of velocity.
The equation of turtle's position as a function of time is given by:
Differentiate the above equation to find the velocity as a function of time:
Differentiating further, we would get the equation for acceleration:
Therefore, initial acceleration is
Force=tension-fg sin ∅
=140-mg sin 18.5
=140-124.35
=15.62N
a=f/m=15.62/40=0.39
now,
v²=u²+2as
=2×0.39×80
v²=62.4
v=7.8m/s
