Answer:

Handwashing with soap has been shown to reduce the risk of gastroenteritis by up to 47%.

Of course, avoiding contaminated foods that could harbor toxic bacteria and parasites is also important.

Explanation:

Here's what I found on the web to further explain and give you more info :) , "Vaccinations are also effective, particularly for rotavirus. The rotavirus The use of clean water and good sanitation practices are important for reducing rates of infectious gastroenteritis.

vaccines have seen a marked decline in the rate and severity of disease in both developing and developed countries.

Oral rehydration is the cornerstone of treatment for those suffering from mild to moderate dehydration. This can be achieved through a solution containing water, salts, and sugar. For severe cases of dehydration, hospitalization and intravenous fluids may be required.

Antibiotics are generally not recommended unless the gastroenteritis is bacterial or parasitic and symptoms are severe.

I hope I helped! :)

Would appreciate Brainliest! ;)

I’m not too sure that there are concrete positive steps you can take to avoid contracting this you can wash fruits and vegetables and avoid sharing eating utensils, vaccinations could also be helpful.

When a rigid body rotates about a fixed axis, all the points in the body have the same A. centripetal acceleration B. tangential
Leto [7]

Answer:

The angular acceleration is same at all the points in the body.

Option (D) is correct.

Explanation:

Given:

When a rigid body rotates about a fixed axis, all the points in the body have the same,

For finding which quantity is same we use pure rotational concept,

 v = \omega r

Where \omega = angular frequency, r = radius of rigid body

When a rigid body rotates about a fixed axis angular velocity of all the points in the body are same.

But the tangential speed, tangential acceleration, linear displacement, and centripetal acceleration depend on the position of the points and hence they are not the same.

Therefore, the angular acceleration is same at all the points in the body.

There is a dropping of a coconut of 2kg mass. the speed of the coconut at the moment before it hits the ground is 40m s-1.
igor_vitrenko [27]
  • Mass=2kg
  • Velocity=40m/s

We know

\boxed{\sf K.E=\dfrac{1}{2}mv^2}

  • m denotes to mass
  • v denotes to velocity

\\ \sf\longmapsto K.E=\dfrac{1}{2}\times 2\times 40^2

\\ \sf\longmapsto K.E=40^2

\\ \sf\longmapsto K.E=1600J

Block 1, of mass m1 = 2.70 kg , moves along a frictionless air track with speed v1 = 27.0 m/s . It collides with block 2, of mas
ki77a [65]

Answer:

a) Block 1 = 72.9kgm/s

Block 2 = 0kgm/s

b) vf = 1.31m/s

c) ∆KE = 936.36Joules

Explanation:

a) Momentum = mass× velocity

For block 1:

Momentum = 2.7×27

= 72.9kgm/s

For block 2:

Momentum = 53(0) (body is initially at rest)

= 0kgm/s

b) Using the law of conservation of momentum

m1u1+m2u2 = (m1+m2)v

m1 and m2 are the masses of the block

u1 and u2 are their initial velocity

v is the common velocity

Given m1 = 2.7kg, u1 = 27m/s, m2 = 53kg, u2 = 0m/s (body at rest)

2.7(27)+53(0) = (2.7+53)v

72.9 = 55.7v

V = 72.9/55.7

Vf = 1.31m/s

c) kinetic energy = 1/2mv²

Kinetic energy of block 1 = 1/2×2.7(27)²

= 984.15Joules

Kinetic energy of block 2 before collision = 0kgm/s

Total KE before collision = 984.15Joules

Kinetic energy after collision = 1/2(2.7+53)1.31²

= 1/2×55.7×1.31²

= 47.79Joules

∆KE = 984.15-47.79

∆KE = 936.36Joules
