Answer:
area = 5733.33 cm²
length = 5.47 × cm
Explanation:
Given data
density = 19.32 g/cm³
mass = 33.16 g
thickness = 3.000 µm = 3 × cm
radius r = 1.000 µm = 1 × cm
to find out
area of the leaf and length of the fiber
solution
we know volume formula that is
volume = mass / density
volume = 33.16 / 19.32
volume = 1.72 cm³
we know that volume = thickness × area
so area
area = volume / thickness
area = 1.72 / 3 ×
area = 5733.33 cm²
and
we know volume = πr²L
so L = volume / πr²
length = 1.72 / π(1×)²
length = 5.47 × cm
The error in Horatio's diagram is that the magnetic field does not continually spread outward from the wire.
<h3>What is electromagnetism?</h3>
Electromagnetism is the process where electric fields and magnetic fields interact and produce difference on effects on the materials around them.
In electromagnetism, electric current is produced from magnets and vice versa.
Based on the laws of electromagnetism, the error in Horatio's diagram is that the magnetic field does not continually spread outward from the wire.

This is the reason why the path at which a ray of light strikes a prism is different to the path after emergence from the other side. There is a refraction of light ray when the light passes from one medium to another at angle. Its speed changes. The bend is in one direction if the material it enters is denser, and other direction if less dense. The amount of bending is different because of different wavelengths.
Answer:
W= 565.42 J
Explanation:
Given that
mass , m =20.5 kg
displacement = 5.93 m
Applied force ,F= 95.3501 N
Coefficient of friction ,μ = 0.389
We know that work done by force F is given as
W= F .d
d=Displacement
F=Force
W=Work
W= 95.3501 x 5.93 J
W= 565.42 J
Therefore the work done by applied force will be 565.42 J.
