Individuals suffering from somatoform disorders often see several doctors about their symptoms because doctors often refer their patients for a second opinion

<h3>What is doctors opinion?</h3>

Doctors usually ask people to take different medications to be able to treat the cause and the symptoms of a disease.

For example, they might prescribe antibiotics to treat the infection and  anti-inflammatory medication for the swelling and pain.

According to this, the statement that says that doctors often advise a combination of treatments to eradicate an infection and treat symptoms is true.

yanalaym [24]

The spin quantum number is represented by the symbol m s a nd has the possible values  +1/2.-1/  corresponding to the two directions of the electron's magnetic field.

The magnetic quantum quantity tells us what number of orbitals there are in a subshell and the feasible orientations of those orbitals. Its value is dependent on the angular momentum quantum range.

The  magnetic discipline is an area in area close to a magnet or an electric contemporary wherein a physical area is produced from a shifting electric rate that creates force on some other shifting electric rate. An instance of a magnetic field is the Earth's magnetic

All magnets have north and south poles. contrary poles are drawn to every other, whilst the identical poles repel each different. when you rub a chunk of iron alongside a magnet, the north-in search of poles of the atoms in the iron line up inside the identical route. The force generated by using the aligned atoms creates a magnetic subject.

Qual a massa de água a 45 °C que devemos misturar com 200 g de água a 15 °C, para que o sistema entre em equilíbrio térmico a 35
Stells [14]

Responda:

400 g

Explicação:

Dado o seguinte:

Deixe Mass (m1) = m em t1 = 45 ° C

Massa (m2) = 200g em t2 = 15 ° C

Equilíbrio térmico (T) = 35 ° C

Usando a relação:

m1 * C * ΔT = m2 * C * ΔT

Onde m1 e m2 são as massas; C = capacidade de calor específico da água e ΔT é a mudança de temperatura

m1 * ΔT = m2 * ΔT

m * (45 ° C - 35 ° C) = 200 * (35 ° C - 15 ° C)

10 * m = 200 * 20

10 * m = 4000

m = 4000/10

m = 400g
