2. Under Appearance and Personalization, click Adjust screen resolution.
3. Click the drop-down list next to Resolution,
4. Move the slider to the resolution you want
5. Click Apply.
Answer:
Speed = 0.866c
Where c is speed of light
Explanation:
We want to find the speed at which it run at a rate that is one-half the rate of a clock at rest.
Thus, we will use time dilation equation to solve it.
Thus;
t_o/√[1 - (v²/c²)] = 2t_o
Where:
t_o is time at rest
v is the speed at which it runs
c is the speed of light.
t_o will cancel out to give;
1/√[1 - (v²/c²)] = 2
Rearranging, we have;
√[1 - (v²/c²)] = ½
Let's make v the subject of the formula;
Let's square both sides to get;
1 - (v²/c²) = ½²
1 - (v²/c²) = ¼
Rearrange to get;
1 - ¼ = v²/c²
¾ = v²/c²
Take square root of both sides to get;
v/c = √¾
v = c × 0.866
v = 0.866c
Answer:
Please find the code and its output in the attached file.
Explanation:
In the above-given code, an interface "Runner" is defined, inside the interface, an abstract method run is declared.
In the next step, three class "Athlete, Machine, and PoliticalCandidate" s defined that implements the run method, and use the print message that holds a given value as a message.
In the next step, a class "DemoRunners" is defined, and inside the main method, the three-class object is declared, which calls the run method.
