Answer:
C. 14.4 kwhr.
Explanation:
To calculate the energy used by appliance first calculate the power. The formulae for calculating power(<em>P</em>) is 
, where V stands for voltage and I stands for current.
In the given problem, V = 240 volts and I = 15 amp. Therefore,
Now, formulae for calculating energy used i.e. work(W) is 
, where <em>t</em> is the time.
In the given question time is 4 hr. Therefore energy used will be,
Energy used (W) = 
.

Explanation:
Freeware and shareware programs are softwares which are either free of charge or consist of a free version for a certain trial period. These programs pose a threat of habouring malware or viruses which could damage one's computer and important files and programs. Therefore, it is imperative that carefulness is maintained when trying to get these softwares.
Some of the necessary safety conditions that should be taken include;
1) Appropriate research about the software including taking more about the vendors and reviews.
2.) Once, a healthy review has been identified ; the download can begin with the Downloader ensuring that the download is from the recommended site.
3) Prior to installation the software should be scanned with an active anti-virus program to determine if there is possibility that a virus has creeped in.
4.) Some softwares may require that computer anti-virus be turned off during installation, this is not always a good idea as this act leaves the system vulnerable a d badly exposed.
Well in my opinion is that yes they do. The ability to be able to communicate with others so far way really helps society advance towards the future. And i cant stress of how the benefits of being able to share ideas with well anyone is so wonderful.
I hope this helps.
Explanation:
Explanation:
RSA encryption is performed by calculating C=M^e(mod n).
However, if n is much larger than e (as is the case here), and if the message is not too long (i.e. small M), then M^e(mod n) == M^e and therefore M can be found by calculating the e-th root of C.
