Answer:
D. 4x as much
Explanation:
The answer is pretty simple. The question is asking about 10m/s and 20m/s right? Take a look at the energy at each point on the graph. At 10m/s the kinetic energy is 100 on the graph. At 20m/s the kinetic energy is 400. You'll notice that 100 x 4 is 400 - That's the answer.
You can also prove this mathematically. The formula for kinetic energy is
The question says: constant mass so we can ignore that for now.
(1/2) * 10^2 is (1/2) * 100 = 50
for the 20m/s ball it would be
(1/2) * 20^2 = 400 * 1/2 = 200
Once again, you see that it is 4x

Explanation:
A webpage gets a new modification date whenever any change is made. This is irrespective of whether the change is large or small, significant or insignificant. Any update to the webpage will change its modification date. But this change will not be carried out automatically everyday unless an actual modification is carried out on that day.Otherwise it will continue to carry the modification date corresponding to the day of last update.
Answer:
All of them apply
Explanation:
Green computing is the process of using environmental friendly computers and its associated components, accessories and other supporting devices.
Virtualization helps us to reduce the number of hardware that we are using.
Grid computers helps us to reduce the use of number of machines and thus supporting the environment in a right way.
Recycling process. Any material that we use needs to be recycled effectively and also in an environmental friendly way.
Autonomic computing uses eco-friendly system which in turn hugely support green computing.
