What is the best definition for hypothermia? Damage to skin caused by long exposure to freezing temperatures Very low internal b

Murljashka [212]

Answer:

Advertisement. When your body temperature drops, your heart, nervous system and other organs can't work normally. Left untreated, hypothermia can lead to complete failure of your heart and respiratory system and eventually to death. Hypothermia is often caused by exposure to cold weather or immersion in cold water.

Based on experimental observations, the acceleration of a particle is defined by the relation a = -(0.1 + sin x/b), where a and

Fiesta28 [93]

Answer:

Velocity,v = 0.323 m/s

Explanation:

The acceleration of a particle is given by :

$a=-(0.1+sin\dfrac{x}{b})$

b = 0.8 m when x = 0

Since, $a=v\dfrac{dv}{dx}$

$v\dfrac{dv}{dx}=-(0.1+sin\dfrac{x}{b})$

$\int{v.dv}=\int{-(0.1+sin\dfrac{x}{b})}.dx$

$\dfrac{v^2}{2}=-[0.1x-0.8cos\dfrac{x}{0.8}]+c$

At x = 0, v = 1 m/s

$\dfrac{1}{2}=0.8+c$

$c=-0.3$

$\dfrac{v^2}{2}=-[0.1x-0.8cos\dfrac{x}{0.8}]-0.3$

At x = -1 m

$\dfrac{v^2}{2}=-0.1(-1)+0.8cos\dfrac{(-1)}{0.8}-0.3$

${v^2}=0.1045$

v = 0.323 m/s

So, the velocity of the particle is 0.323 m/s. Hence, this is the required solution.

The color of an object we see is determined by the

aksik [14]

Answer:

An object appears white when it reflects all wavelengths and black when it absorbs them all. Red, green and blue are the additive primary colors of the color spectrum. Combining balanced amounts of red, green and blue lights also produces pure white.

A straight wire is aligned east-west in a region where Earth’s magnetic field has magnitude 0.0780 mT and direction 67.1° below

Sergio [31]

Explanation:

It is given that,

Earth's magnetic field, $B=0.078\ mT=0.078\times 10^{-3}\ T$

Direction of magnetic field, 67.1 degrees below the horizontal, with the horizontal component directed due north.

The magnetic force on the wire per unit length of wire, $\dfrac{F}{L}=0.0300\ N/m$

(a) The given scenario is shown in the attached figure as :

Using the right hand rule to find the direction of magnetic force on the wire. By using this rule, we get the magnetic force acting on the wire is in upward direction.

(b) Let I is the current flowing in the wire. The magnetic force is given by the following formula as:

$F=ILB$

$I=\dfrac{F}{LB}$

$I=\dfrac{0.0300}{0.078\times 10^{-3}}$

I = 384.61 A

Hence, this is the required solution.
