Homeostasis is the regulation of an organism’s internal environment to maintain conditions suitable for life. homeostasis requires a) competition between the body’s systems. b) balance between all of the body’s systems. c) the body’s systems to act independently of each other. d) maximum growth of all types of cells and tissues within the body.

Mass (kg) force (n) 5 25 10 50 15 75 20 100 a student was trying to find the relationship between mass and force. he placed four different masses on a table and pulled them using a spring scale. the table shows the different masses used in the experiment and the force required to pull each mass. the student concluded that more force was required to pull heavier objects. what comment would you make regarding his conclusion? a) no clear relation can be observed between mass and force from the data. b) there is a direct proportion between the mass and force listed in the table. c) gravity should have been taken into account while performing the experiment. d) there is an inverse proportion between the mass and force listed in the table.

Calculate the mass of an object that has a momentum of 100kg x m/sec and velocity of 4 m/sec

Determine the fraction of the magnitude of kinetic energy lost by a neutron (m1 = 1.01 u) when it collides head-on and elastically with a target particle at rest which is 21h (heavy hydrogen, m = 2.01 u).
