Answer
B. F=ma
Explanation
The Newton's laws of motion tries to explain the how bodies behave and the energy changes when theys are in motion. For the 3 of them to hold, the bodies must be moving in a straight line and with constant velocity.
The second one states that, "the change of momentum of a moving body is directly proportional to the force producing it and it takes place to the direction of force."
From the choices given, the appropriate answer is B. F=ma
Exert force upward.
Like when you pick something up from the floor, or walk up the stairs.
Answer:
Computer A is 1.41 times faster than the Computer B
Explanation:
Assume that number of instruction in the program is 1
Clock time of computer A is 
Clock time of computer B is 
Effective CPI of computer A is 
Effective CPI of computer B is
CPU time of A is
CPU time of B is
Hence Computer A is Faster by 
Computer A is 1.41 times faster than the Computer B
Answer:
A change in color
The formation of a precipitate
A clear liquid becoming cloudy
The formation of bubbles
The formation of smoke
Explanation:
A chemical reaction can be defined as the conversion of reactant into product. The process in which one or more than one substance is converted into one or many different substances.
There are some indications which can provide the evidence that chemical reaction has occurred.
A change in color of the substance, formation or smoke or bubbles. The formation of the precipitate and in case the substance becomes cloudy.
All these evidences show that chemical reaction has occurred.
