Answer:
Gravitational potential energy (GPE) = 107.8J
Explanation:
Gravitational potential energy (GPE) = mgh
Where mass(m) = 11kg
Acceleration due to gravity(g) = 9.8m²/s
height = assumed to be 1m
Force(F) = mg
Force(F) = 11×9.8 = 107.8N
Gravitational potential energy (GPE) = 107.8×1
= 107.8J
Answer:
She passes through a loud spot at x = 19.5m from the first speaker. Constructive interference occurs here.
At the quiet spot destructive interference occurs. The minimum distance for this to occur is 20.25 from the first speaker.

Answer:
Angle turn pulley is 113 rad
Explanation:
given data
angular speed w = 12.5 rad/s
angular acceleration a 3.41 rad/s²
time t = 5.26 s
to find out
what angle does the pulley turn
solution
we get here angle by this equation that is here
angle turn = w × t + 0.5 × a × t² ......................1
put here value we get
angle turn = w × t + 0.5 × a × t²
angle turn = 12.5 × 5.26 + 0.5 × 3.41 × 5.26²
Angle turn = 65.75 + 47.17
Angle turn = 112.92 rad = 113 rad
In an isometric transformation, the shape does not change size.
<h3>What is
isometric transformation?</h3>
A shape-preserving transformation (movement) in the plane or in space is called an isometric transformation (or isometry). The isometric transformations include translation, rotation, and combinations thereof, such as the glide, which combines a translation with a reflection.
A stiff transformation called an isometry keeps perimeter and area constant while preserving length and angle measurements.
As a result, while dilations are not isometric since the image and preimage are comparable figures rather than congruent figures, translations, reflections, and rotations are.

Answer:
Obviously Lengthen... 
or 
Explanation:
As we can observe from the equation, time period of a simple pendulum depends upon the length directly. When the gravitational acceleration increases the time period of the pendulum decreases and vice versa. So, by increasing the length, the time period can be adjusted...
