When a person's temperature reaches 104 degrees, the chances of survival are decreased dramatically. Group of answer choices Tru
Natali5045456 [20]

Answer:

True

Explanation:

With the increase in temperature hypothalamus fails and heatstroke occurs due to this failure. Hypothalamus is the region of our brain that act as a thermostat. It co-ordinates our physiological response to excessive heat. When the person’s temperature reaches to 104 degrees then it causes heatstroke. This heatstroke is very sudden and can kill person. Hence, we can conclude that when person’s temperature reaches to 104 degrees chances of survival decreases dramatically.

Two objects of different masses accelerate at the same rate. According to Newton’s second law of motion, the more massive obje
babymother [125]

Newton's Second law of motion is

F = m * a   ( force = mass * acceleration).

So if a is constant   then a = F 1 / m1  and  a = F2 / m2  then

F1 /m1 = F2 /  m2 and if  m1 > m2 then

F1 must be greater than F2.

Answer is C.

I lift a 20kg ball up 2.5 meters off the ground on Earth.
Umnica [9.8K]

Answer: How much gravitational potential energy does the ball have at this point? At h = 20.4 m the gravitational potential energy of the ball reaches maximum.  

How much work did I do lifting up the ball?  As you are lifting the object you are doing work on the object. The work W done on an object by a constant force is defined as W = F·d. It is equal to the magnitude of the force, multiplied by the distance the object moves in the direction of the force.
