Answer:
getSource()
Explanation:
Every event object has the getSource() method that can be used to identify the component that triggered the event.
For example , if a button is pressed on the user interface, this results in its event handler code getting executed. The event handler takes as parameter an Event object. This event object reference can then be used by the handler code to access the event source reference by calling event.getSource() .
Answer:
<u>lysosomes</u>
Explanation:
Cell Digestion and the Secretory Pathway. The primary sites of intracellular digestion are organelles known as the lysosomes, which are membrane-bounded compartments containing a variety of hydrolytic enzymes.
Answer:
The advantages and disadvantages of recovery strategies are described.
Explanation:
1. Weekly full server backups with daily incremental backups: It is recommended to run full copies periodically for example weekly and between copy and full copy make incremental or differential copies. Daily full server backups: It is not recommended to make copies on the same server where the information is located. Disadvantage larger storage space.
2. Daily full server backups with hourly incremental backups: Less storage space than full or differential copy. Minor copy window. Disadvantage - if any dependent copy fails, the copy cannot be restored.
3. Redundant array of independent (or inexpensive) disks (RAID) storage devices with periodic full backups: RAID allows you to store the same data redundantly (in multiple paces) in a balanced way to improve overall performance. RAID disk drives are used frequently on servers but aren't generally necessary for personal computers.
4. Replicated databases and folders on high-availability alternate servers: Easy recovery. You have all the data copied.
let's say they catch-up to each other after t hour.
so
in t hour distance travelled by Renee
d = speed × time = 50t
in t hour distance travelled by Kim
d = speed × time = 60(t-1) + 0×1 = 60(t-1)
Note: here kim didn't covered any distance in first hour and in rest t-1 hour it travelled all distance
now.as distance travelled by both is same so
60(t-1) = 50t
60t -60 = 50t
adding 60 both sides
60t = 50t+60
subtracting 50t both sides
60t -50t = 50t+60 - 50t
10t = 60
dividing by 10 both sides
t = 60/10 = 6
so in 6 hour both will catch-up to each other
