Hypothesis: Enriched environments will have a positive effect and better performance of the experimental group of animals exposed to toys in comparison to the control group of animals in running in mazes.
Dependent Variable: Control Group
Independent Variable: Exposed/Experimental Group
Answer:
For the purposes of your question, we can think of speed and velocity as being the same thing. Therefore, the kinetic energy of an object is proportional to the square of its velocity (speed). In other words, If there is a twofold increase in speed, the kinetic energy will increase by a factor of four.
Explanation:
Answer: 3000 Newton
Explanation:
Mass of large car = 1000 kg.
Acceleration of the car = 3 m/sec2
Force = ?
Recall that force is the product of mass of an object and the acceleration by which it moves.
Thus, Force = Mass x Acceleration
Force = 1000 kg x 3 m/sec2
= 3000 Newton
Thus, 3000 Newton of force would be required to accelerate the car
