Answer;

0.25 g/cm^3

Explanation;

25 % of 1 g/cm^3

=  0.25 g/cm^3

Water's density is 1 g/ml. Objects with a density greater than 1g/ml will sink when placed in water.

Objects with a density less than one will float when placed in water. If a block has a density of 0.1g/cm3 it will float because it's density is less than 1.

The percent of the block that will be below the water depends on the density of the floating object. To find the percentage of the object below the water we just convert the density of the object as a percentage.

A Cessna aircraft has a lift off speed of 147 km/h. What minimum constant acceleration does this require if the aircraft is to b
netineya [11]

Answer:

The acceleration is  a =51945 \ km/h^2

Explanation:

From the question we are told that

   The lift up speed is  v  = 147 \  km/h

    The distance covered for the take off run is s =  208 m = 0.208 \ km

Generally from kinematic equation we have that

      v^2 = u^2 + 2as

Here u is the initial  speed of the aircraft with value 0 m/ s give that the aircraft started from rest

So  

    147^2 = 0^2 + 2* a* 0.208

=>  a =51945 \ km/h^2

Which of the following is responsible for the overall integration of the autonomic nervous system (ANS)?
Dafna1 [17]

Answer:

D. hypothalamus

Explanation:

The autonomic nervous system (ANS) is a component of the peripheral nervous system that is in charge of the involuntary functions, this means it regulates the flight-or-fight response, heart and respiratory rate, sexual arousal, urination, etc.<em> The hypothalamus is the integrator of these functions, it receives the information from the nervous system and responds to it.</em>

I hope you find this information useful and interesting! Good luck!
