Can lack of sleep cause muscle injuries?

Talja [164]

sleeps help in muscle recovery, so when we do not sleep or lack of sleep it leads to inflammation in muscles, which causes pain in muscles.

Sleep and pain both have relation.

Poor sleep schedule causes this muscle pain intensity to increase

In addition to inflammation and pain, it also decreases the tolerance of pain.

As we know sleep heals the muscle and fasten any injury caused to muscle, lack of it causes the healing slow.

This inflammation in muscle causes poor performance in the body.

If raindrops are falling vertically at 8.30 m/s, what angle from the vertical do they make for a person jogging at 2.07 m/s?

dmitriy555 [2]

Answer:

∆ = 14°

Explanation:

Let the angle be ∆

Opposite = 2.07 m/s

Adjacent = 8.3 m/s

Tan ∆ = opposite / adjacent

Tan ∆ = 2.07 / 8.3

Tan ∆ = 0.2494

∆ = ArcTan (0.2494)

∆ = 14°

The angle from vertical the raindrops make for a person jogging is 14°

Recessed incandescent luminaires not marked type ic and those marked for installing directly in ___________ must not have insula

slavikrds [6]

Answer:

Recessed incandescent luminaires not marked type ic and those marked for installing directly in insulated ceilings must not have insulation over the top of the luminaire.

Explanation:

Depending on how they interact with insulation, lighting fixtures are rated at various levels. Non-IC rated lighting fixtures can accommodate higher wattage bulbs, but they also pose the greatest fire risk when used with the incorrect insulation.

In locations with insulation, light fixtures that are not IC rated may be installed. But there is a condition. The distance between the fixture and any insulation should be 3 inches. But the 3 inch gap in the insulation would negate the goal of insulation by producing a lot of uninsulated space, so this defies logic. Building a box-style cover to cover the fixture on the attic side is one option to fix this. Drywall or foil-faced foam insulation can be used to create this box. After the cover is put in place, insulation can be added for maximum effectiveness.

A "biconvex" lens is one in which both surfaces of the lens bulge outwards. Suppose you had a biconvex lens with radii of curvat

madam [21]

Answer:

12 cm

Explanation:

We shall use Lens makers formula here which is as follows

$\frac{1}{F} =(\mu-1) (\frac{1}{R_1} -\frac{1}{R_2})$

Put μ = 1.5 , R₁ = 10 cm ,R₂ = - 15 cm ( according to sign convention )

$\frac{1}{F} =(1.5-1) (\frac{1}{10} -\frac{1}{-15})$

= .5 x ( 15 + 10 ) / 15 x 10

= $\frac{25}{2\times10\times15}$

F = 12 cm
