Answer:
ΔT = 
Explanation:
In a simple harmonic motion, specifically in the simple pendulum, the angular velocity
w = 
angular velocity and period are related
w = 2π / T
we substitute
2π / T = \sqrt{\frac{g}{L} }
T = 
In this exercise indicate that for a long Lo the period is To, then and increase the long
L = L₀ + ΔL
we substitute
T = 
T = 
in general the length increments are small ΔL/L «1, let's use a series expansion
we keep the linear term, let's substitute
T = 
if we do
T = T₀ + ΔT
T₀ + ΔT = 
T₀ + ΔT = T₀ + 
ΔT =

Answer: Earth's orbital path around the Sun</h2><h2>
</h2>
The <u>Ecliptic</u> refers to the orbit of the Earth around the Sun. Therefore, <u>for an observer on Earth it will be the apparent path of the Sun in the sky during the year, with respect to the "immobile background" of the other stars.</u>
<u />
It should be noted that the ecliptic plane (which is the same orbital plane of the Earth in its translation movement) is tilted with respect to the equator of the planet about 
approximately. This is due to the inclination of the Earth's axis.
Hence, the correct option is Earth's orbital path around the Sun.

Answer:
80%
Explanation:
Efficiency of machine = work output/work input ×100 %
From question, work output = 20J
Work input = 25J.
Therefore efficiency = 20/25 × 100 %
Efficiency = 20×4 %
Efficiency = 80%

Answer:
4.399 Nm
Explanation:
The maximum Torque on a coil is given as,
τ = BNIA...................... Equation 1
Where τ = Maximum torque exerted on the coil, B = Magnetic Field, N = Number of turns, I = Current, A = Area.
Given: N = 45.5 Turns, B = 0.49 T, I = 26.7 mA = 0.0267 A,
A = πr², Where r = radius of the coil, r= 4.85 cm = 0.0485 m
A = 3.14(0.0485)²
A = 7.39×10⁻³ m².
Substitute into equation 1
τ = 45.5×0.49×26.7×7.39×10⁻³
τ = 4.399 Nm
