Period of a simple pendulum = 2π √(L/G)
(360s/100) = 2π √(1.2m/G)
1.8s / π = √1.2m / √G
√G · (1.8s/π) = √1.2m
√G = (π · √1.2m) / 1.8s
Square each side:
G = π² · 1.2m / 3.24 s²
G = (1.2 · π² / 3.24) m/s²
G = 3.66 m/s²
So I just went and looked up Mars gravity. Floogle says it's 3.711 m/s² there.
That seems awfully close ... only 1.4% greater than our astronauts measured.
You don't suppose . . . . .
When the object is at the focal point the angular magnification is 2.94.
Angular magnification:
The ratio of the angle subtended at the eye by the image formed by an optical instrument to that subtended at the eye by the object when not viewed through the instrument.
Here we have to find the angular magnification when the object is at the focal point.
Focal length = 6.00 cm
Formula to calculate angular magnification:
Angular magnification = 25/f
= 25/ 8.5
= 2.94
Therefore the angular magnification of this thin lens is 2.94

The number of turns of wire is directly proportional to voltage.
The higher the number of turns of wire the higher the voltage
Since .
Power (output) of a generator = voltage x current. Therefore the higher the voltage the higher the output of the generator.
So, the higher the number of turns of wire the higher the output of the generator.

The speed of a wave is 40 m/s. If the wavelength is 80 centimeters, what is the frequency of the wave ?
<h2><u>A</u><u>n</u><u>s</u><u>w</u><u>e</u><u>r</u>:-</h2>
<h3>Given:-</h3>
Velocity (V) = 40 m/s
Wavelength = 80 cm = 0.8 m
<h3>To Find:-</h3>
The frequency (F) of the wave.
<h2>Solution:-</h2>
We know,
40 = F × 0.8
F =
F = 50
<h3>The frequency of the wave is <u>5</u><u>0</u><u> </u><u>H</u><u>z</u>. [Answer]</h3>
Answer:
When the tree is at rest, its leaves are also at rest. But when we bring the tree in motion by means of shaking it, due to the inertia of leaves they still tend to be in rest. Thus, force is acting on leaves vigorously with changing direction rapidly. This results in detaching of leaves from the tree.
