Answer and Explanation
In the United States of America, driver's licenses are issued by each individual state, territory.
In order for a driver to graduate from a learner's license to an operator's license, how many hours of driving you need to be documented is 50 hours, of which 10 hours must be at night.To move on to your intermediate driver's license, you must: Be at least 16 years old .
Failure in a database environment is more serious then a non data base because if you lose important information you may not get it back and failure in a nondatabase environment the problem may be more easier to solve
Answer: Star topology is commonly used these days.
Explanation:
- As, start topology is the reliable network topology because the failure of a central node or a node cable does not affect the remaining other nodes.
- In star topology, if the computer fails you can still access your data by using backup folder in your private file or folder.
- In this network topology it is easy to find faults and correct it timely.
- The start topology is cost effective and easy to maintain.
- We can also connect multiple communication channels.
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
