<u>Benefits of strength and muscular endurance exercises and two examples:</u>
Of several purposes, muscle strength and endurance are beneficial, like as follows
- increasing potential to do things such as doing daily routine work
- carrying boxes or wood cutting before getting exhausted
- reducing the risk of injury
- helping you to maintain a healthy body weight
- contributing to healthier muscles and bones
- enhancing morale and feeling about yourself.
The two examples for strength and muscular endurance exercises are: Plank and Body weight squats.
Squats shape the human body part which is used to sit (butt) and entire body, reduce fat, strengthen posture, increase blood circulation, boost your flexibility.
While plank helps to reinforce the heart, hikes metabolism, decline back pain by supporting backbone, improved joint health, balance mood and relieved stress.
Answer:
I₃/Io % = 0.8.59
Explanation:
A polarizer is a complaint sheet for light in the polarization direction and blocks the perpendicular one. When we use two polarizers the transmission between them is described by Malus's law
I = I₀ cos² θ
Let's apply the previous exposures in our case, the light is indicatively not polarized, so the first polarized lets half of the light pass
I₁ = ½ I₀
The light transmitted by the second polarizer
I₂ = I₁ cos² θ
I₂ = (½ I₀) cos2 28
The transmission by the polarizing third is
I₃ = I₂ cos² θ₃
The angle of the third polarizer with respect to the second is
θ₃ = 90-28
θ₃ = 62º
I₃ = (½ I₀ cos² 28 cos² 62)
Let's calculate
I₃ = Io ½ 0.7796 0.2204
I₃ = Io 0.0859
I₃/Io= 0.0859 100
I₃/Io % = 0.8.59

Answer:
500km per hour
Explanation:
if in 2 hours the airplane flies 1000 km then 1000 divided by 2 is 500km per hour.
Answer:
0.3376 mm
Explanation:
The computation of the spacing in mm between the slits is shown below:
As we know that
where,
= wavelength
L = distance from the scrren
= spanning distance
As there are 11 bright fingers seen so m would be
= 11 - 1
= 10
Now placing these values to the above formula
So, the spacing is
= 0.3376 mm
We simply applied the above formula.
