Answer:

B

Explanation:

Let m be mass of the object and v be speed of object b.

Kinetic Energy of B = 1/2 mv^2

Kinetic Energy of A = 1/2 m(2v)^2

= 2 mv^2

= 4 (1/2 mv^2)

= 4 × Kinetic Energy of B

Hence Object A has four times the kinetic energy of object B (<em>A</em><em>n</em><em>s</em><em> </em><em>B</em><em>)</em>

Ksivusya [100]

Answer

The dedicated graphics card is used when performing hardware-intensive tasks so as to ensure efficiency and balanced performance. However, it uses more power and thus produces more heat. When the cooling system is not sufficient or the room is not well ventilated, your PC begins to overheat while playing games.     Explanation: How does the second law of thermodynamics relate to the direction of heat flow? Heat of itself never flows from a cold object to a hot object. ... The second law expresses the maximum efficiency of a heat engine in terms of hot and cold temperatures. one of these answers i am not sure
