Consider three force vectors F~ 1 with magnitude 43 N and direction 38◦ , F~ 2 with magnitude 26 N and direction −140◦ , and F~
Rama09 [41]

Answer:

34.70 N

Explanation:

Given :

F~ 1 = 43 N in direction 38◦

F~ 2 = 26 N in direction −140◦

F~ 3 = 27 N in direction 110◦

Therefore,

F~x = 43 cos (38) + 26 cos (-140) + 27 cos (110)

      = 43  (0.7) + 26  (-0.7) + 27  (-0.3)

      =  3.8

F~y = 43 sin (38) + 26 sin (-140) + 27 sin (110)

      = 43  (0.6) + 26  (-0.6) + 27  (0.9)

      = 34.5

so, F~ = $ \sqrt{3.8^2 + 34.5^2}$

          = 34.70 N

A ball is revolving horizontally in a circle of radius 1.8 m, and is held by a rigid, massless rod. The mass of the ball is 0.1
OLga [1]

Answer:

 \omega=15 \ rad/s

Explanation:

given,

radius of circle = 1.8 m

mass of the ball = 0.1 Kg

linear speed of the ball = 27 m/s

angular velocity of orbit = ?

 v =  r \omega      

ω is the angular speed of the circle

 \omega=\dfrac{v}{r}      

 \omega=\dfrac{27}{1.8}        

 \omega=15 \ rad/s              

the angular velocity of the orbit is \omega=15 \ rad/s

Which client body temperatures are indicative of moderate hypothermia? select all that apply. one, some, or all responses may be
Lyrx [107]

The correct option is (3)  88° F (31.1° C) and (4) 92° F (33.3° C).

A medical emergency known as hypothermia happens when your body results in a dangerously low body temperature.

What is Hypothermia?

  • After being exposed to chilly, rainy, or windy environments, hypothermia develops.
  • Your body eventually exhausts its reserves of energy after prolonged exposure to cold temperatures, which causes your body temperature to drop.
  • When the body's temperature falls below 95° F (35° C), hypothermia sets in. The average body temperature is 37° C (98.6° F).
  • A medical emergency is hypothermia. The brain and body cannot operate normally when a person's body temperature is dangerously low. Hypothermia can cause cardiac arrest (heart stops beating) and death if it is not addressed.
