what is the difference between a respirator and a ventilator

Answer:

I think it's B, if that's wrong I apologize. You might want to do more research on it and find the correct answer if you can, if it's right then you could like my comment, so others know if not give it 1 star, keep it low lol.

Explanation:

The line that represents the greatest positive acceleration is A.

In a velocity-time graph, the slope of the line represents the acceleration. The greater the slope, the greater the acceleration. Line A has the steepest slope, so it represents the greatest positive acceleration.

Line B has a positive slope, but it is not as steep as line A. Line C has a negative slope, which means it represents negative acceleration, or deceleration. Line D is a horizontal line, which means it represents a constant velocity, or zero acceleration.

Therefore, the line that represents the greatest positive acceleration is A.

We have that with v_1 =v this goes to show that  the velocity of the bigger block after the collision takes place is v

From the question we are told

Suppose the blocks collide elastically. picking the positive direction to the right, what is the velocity of the bigger block after the collision takes place?

Generally the equation for Momentum   is mathematically given as

P=mv

Therefore

[tex]m_1v_2=m_2v_2[/tex]

Hence

[tex]v_1=\frac{m_2v_2}{m_1}[/tex]

Therefore

[tex]v_1=\frac{mv_2}{2m}\\\\v_1=\frac{v_2}{2}[/tex]

Hence

[tex]2v+v=v_1+v_2\\\\v_1=v[/tex]

Now

with v_1 =v this goes to show that  the velocity of the bigger block after the collision takes place is v

Answer:

the free body diagram models the forces acting on an object. The object or 'body' is usually shown as a box or a dot. The forces are shown as thin arrows pointing away from the centre of the box or dot. ... It is important to label each arrow to show the magnitude of the force it represents.

Answer:

Distance, d = 0.1 m

It is given that,

Initial velocity of meson,

Finally, the meson is coming to rest v = 0

Acceleration of the meson,  (opposite to initial velocity)

Using third equation of motion as :

s is the distance the meson travelled before coming to rest.

So,

s = 0.1 m

The meson will cover the distance of 0.1 m before coming to rest. Hence, this is the required solution.  

Answer:

Thrust acts on the accelerated object in the direction opposite to the applied force hence it accelerates the object in the direction opposite to the applied force. ... Its magnitude is equal to that of applied force. It always increases the velocity of the object.

The best description of the role of glucose in the body is that it is the food converted into fuel. Details about role of glucose can be found below.

Cellular respiration is the process by which living organisms obtain energy for their daily activities by breaking down food molecules in their cells.

The food ingested by living organisms is digested into the simplest form called glucose. The glucose is then broken down during cellular respiration.

During cellular respiration, glucose is broken down to produce energy (ATP), which is the fuel for metabolic activities in the body.

Drinking water usually helps with gaining hydration cause usually when you get sick you get weak. thats what u think though

Water will help expel toxins from the body that's why it is recommended to sick people to consume more water. Therefore, option (A) is correct.

Proper hydration can be helpful to the skin and mucous cell membranes play a barrier to stop bacteria from entering the body when sick with a virus. Fluid can also help decrease irritation when sneezing, coughing, and even breathing.

Water can help to regulate body temperature, maintain healthy skin and joints, digest food, and help the brain function at its best. Producing requires bodily fluids, like tears and saliva, and removing waste through sweat, and urination.

Dehydration can happen when we lose a high amount of bodily fluids than we’re consuming. This can occur through bodily functions that bring the loss of fluids and electrolytes.

Therefore, it is important to stay hydrated when you are sick.

Spiral galaxies are also known as twisted collection of stars and gas that have often beautiful shape and are made up of hot young stars.

There are various types of galaxies based on their shapes such as spiral, elliptical, oval etc. The spiral shaped galaxies are called spiral galaxies.

Galaxies are a groups of stars, dust and dark matter which are connected by the gravitational force. There are billions of galaxies in the universe and each containing trillions of stars. The galaxy nearest to earth is milky way.

The spiral structure that radiate from the galactic disc's core and give spiral galaxies their name. The central bulge, at the ends of which the spiral arms originate, is seen to have an additional component in the shape of a bar-like structure in about two-thirds of all spirals.

Nearly the course of the universe's history, the ratio of barred spirals to barless spirals has probably varied, going from only 10% approximately 8 billion years ago to about a quarter 2.5 billion years ago to over two-thirds of the galaxies in the observable universe at the present.

In terms of both price and availability, the Birkin bag is as elusive as it is exclusive. For more than two decades, the bag has been the most sought item in the handbag industry. For such a modest bag, that's a lot of staying power (in looks alone, the design itself takes some 18 hours and is done by a single craftsman).

Of course, it's likely that the bag's rarity is what keeps it at the top of every want list. It is difficult, for example, to stroll into a Hermès store and buy a bag –– even if you could afford to pay the minimum price of $10,000. No, you have to be on an elite list to receive a Birkin.

Answer:

P = m (v2 - v1)     change in momentum

P = - m v1  if v2 is to be zero

F = P / t     change in momentum equals applied force

F = m a = - m v1 / t

a = -v1 / t     or a * t = -v1`

Any combination of a and t that is greater than v1 will bring the space station to a halt

If a is small then t must be large

Any applied force will eventually bring the ship to a halt and then begin the acceleration towards the starting point
