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.

To know more about lack of sleep,

The energy flow to the earth from sunlight is about 1.40 kw/m2 . part a find the maximum value of the electric field for a sinus

Lilit [14]

Energy ,E= Sqrt{Energy intensity*Speed of light*Magnetic constant}

Where,
Energy intensity = 1.40 kW/m^2 = 1400 W/m^2
Speed of light = 3*10^8 m/s
Magnetic constant = 4pi*10^-7 H

Therefore,
E= Sqrt{1400*3*10^8*4*pi*10^-7} = 726.49 v/m

Now,
Emax = E*sqrt (2) = 726.49*Sqrt(2) = 1027.41 v/m

2. A 2,000 kg rocket is launched 12 km straight up at a constant acceleration into the sky at which point the rocket is travelli

Mice21 [21]

Answer:

797700000 J

Explanation:

From the question,

The work done by the rocket, is given as,

W = Ek+Ep............. Equation 1

Where Ek and Ep are the potential and the kinetic energy of the rocket respectively.

Ep = mgh............ Equation 2

Ek = 1/2mv²............. equation 3

Substitute equation 2 and equation 3 into equation 1

W = mgh+1/2mv².............. Equation 4

Where m = mass of the rocket, h = height, v = velocity of the rocket, g = acceleration due to gravity.

Given: m = 2000 kg, h = 12 km = 12000 m, v = 750 m/s, g = 9.8 m/s²

Substitute into equation 4

W = 2000(12000)(9.8)+1/2(2000)(750²)

W = 235200000+562500000

W = 797700000 J

Sam drives her scooter 7 kilometres north. She stops for lunch and then drives

Talja [164]

Answer:

1. Distance travelled = 12 km.

2. Displacement = 8.6 km

Explanation:

From the question given above, the following data were obtained:

Distance 1 (d₁) = 7 km

Distance 2 (d₂) = 5 km

Total distance =?

Displacement =?

1. Determination of the distance travelled.

Distance 1 (d₁) = 7 km

Distance 2 (d₂) = 5 km

Total distance (dₜ) =?

dₜ = d₁ + d₂

dₜ = 7 + 5

dₜ = 12 km

2. Determination of the displacement.

In the attached photo, R is the displacement.

We can obtain the value of R by using the pythagoras theory as illustrated below:

R² = 7² + 5²

R² = 49 + 25

R² = 74

Take the square root of both side

R = √74

R = 8.6 km
