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.

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

I need help with question 26<br>this is from my physics textbook
Neko [114]

Suppose a,b,c are measured in meters. Then the semiperimeter s=\dfrac{a+b+c}2 is also given in meters, so s-a,s-b,s-c are all also given in meters. When multiplied together, (s-a)(s-b)(s-c) is measured in cubic meters. Divide this by s, measured in meters, and this reduces to square meters. Take the square root and you end up back with meters once again. So the formula is indeed dimensionally consistent.

The 30-kg disk is originally spinning at v = 125 rad&gt;s. If it is placed on the ground, for which the coefficient of kinetic f
irga5000 [103]

Answer:

t = 3.82 s

Ax = 147 N  (←)

Ay = 294 N   (+↑)

Explanation:

Given

m = 30.0 Kg

ωinitial = 125 rad/s

ωfinal = 0 rad/s

μC = 0.5

R = 0.3 m

t = ?

Ax = ?

Ay = ?

For the disk, we can apply

∑ τ = I*α

where I = m*R²/2

then

⇒ R*Ffriction = (m*R²/2)*α

⇒ R*(-μC*N) = R*(-μC*m*g) = (m*R²/2)*α

⇒ α = -2*μC*g / R

⇒ α = -2*(0.5)*(9.8) / 0.3 = -32.666 rad/s²

we can use the equation to get t:

α = Δω / t      ⇒   t = Δω / α = (0 - 125) / (-32.666)

⇒   t = 3.82 s

The horizontal and vertical components of force which the member AB exerts on the pin at A during this time are

∑ Fx = 0  (+→)

Ax - Ffriction = 0

⇒  Ax = Ffriction = μC*m*g = (0.5)*(30)*(9.8) = 147 N

⇒   Ax = 147 N  (←)

∑ Fy = 0   (+↑)

⇒  Ay - m*g = 0

⇒  Ay = m*g

⇒  Ay = 30*9.8 = 294 N

⇒  Ay = 294 N   (+↑)

A car, starting from the origin, travels
sweet [91]

Answer:

The net displacement of the car is 3 km West

Explanation:

Please see the attached drawing to understand the car's trajectory: First in the East direction for 4 km (indicated by the green arrow that starts at the origin (zero), and stops at position 4 on the right (East).

Then from that position, it moves back towards the West going over its initial path, it goes through the origin and continues for 3 more km completing a moving to the West a total of 7 km. This is indicated in the drawing with an orange trace that end in position 3 to the left (West) of zero.

So, its NET displacement considered from the point of departure (origin at zero) to the final point where the trip ended, is 3 km to the west.

A 1.5kg piece of copper is set out in the sun. Its temperature rises from
Nata [24]

Answer:

<u>8.13 kJ</u>

Explanation:

Q = mCT where Q is the energy (in Joules, here), m is the mass (kg, here) C is the specific heat, and T is the temperature (C).

Q = mCT

Q = (1.5kg)*((387J/(kg*C))*(14C)

Q = 8127 J, or 8.13 kJ with 3 sig figs.
