a. The period of the pendulum for the given Length = 23 cm is 0.962 s
b. The period of the pendulum for the given Length = 192 cm is 2.779 s
<h3>What is time period of the pendulum?</h3>
When the bob of the pendulum is displaced from its equilibrium position and starts swinging from one end to another end or to and fro. The time taken to complete one cycle is called the time period.
The expression for finding the time period is
T = 2π√l/980
Given, the length of the pendulum l,
a. L =23 cm
Put the value into the expression of Time period, we get
T = 2π√(23/980)
T =0.962 s
a. L =192 cm
Put the value into the expression of Time period, we get
T = 2π√(192/980)
T =2.779 s

Answer:
∠ A ≅ ∠ E
∠ K = 60°
Step-by-step explanation:
Part 1.
Given that ABCD ≅ EFGH.
Whenever a quadrilateral is congruent to another, and we write the congruency in symbol, then the order of congruency with respect to angles and sides are maintained in the symbol.
That means if ABCD ≅ EFGH, then ∠ A ≅ ∠ E, ∠ B ≅ ∠ F and so on.
Therefore, in this case, ∠ A ≅ ∠ E (Answer) {It is also shown in the diagrams}
Part 2.
Given that, Δ EFG ≅ Δ KLM
Hence, ∠ E ≅ ∠K, ∠ F ≅ ∠ L, and ∠ G ≅ ∠ M
It is also given that ∠ F = 35° and ∠ G = 85°
So, ∠ E = 180° - ∠ F - ∠ G = 180° - 85° - 35° = 60°
Since, ∠ E = ∠ K,
So, ∠ K = 60°. (Answer)
Answer:
The diameter is 6.76
Please read the exaplanation... it always helps!
Step-by-step explanation:
Area of circle = r^2 pi
if the area is 36 then...
36 = r^2 pi to solve for r divide both sides by pi
36/pi = r^2
11.45 = r^2 take the square root of both sides
√11.45 = r RADIUS = 3.38
then multiply by two since the diameter is 2 (radius) and you get...
diameter = 6.76

Answer:
n = 3.3167 moles
Step-by-step explanation:
The number of mole in water
H2O
n = m/Mm
n = number of mole
m = number of mass
Mm = number of molar mass
Given :
Mass = 59.75g
Mm of H2O
H - 1.00784
O - 15.999
Mm
H = 2 * 1.00784 = 2.01568
O = 15.999
Mm of H2O = 15.999 + 2.01568
= 18.01468
insert the values into the formula
n = m/Mm
n = 59.75/18.01468
= 3.3167moles
