Answer:

C. nslookup

E. ping

Explanation:

The two commands that would confirm this assumption would be nslookup and ping. The command nslookup will show you a mapping of the DNS and the IP address, this includes the name server and how it is being translated to the correct IP address. The ping command will send a small piece of data to the IP address of the website that you are trying to access and listen back for a response. If a response is received it means that the website was reached correctly and is fully operational. Both of these commands combined will allow you to determine whether the technician's assumption was correct.

The net force on a vehicle that is accelerating at a rate of 1.2 m/s2 is 1500 newtons. What is the mass of the vehicle to the ne
Rudiy27

Answer:

The mass of the vehicle is 1250kg

Explanation:

Given

Net\ Force = 1500N

Acceleration = 1.2m/s^2

Required

Determine the vehicle's mass

This question will be answered using Newton's second law which implies that:

Net\ Force (F) =  Mass (m) * Acceleration (a)

In other words:

F = ma

Substitute values for F and a

1500 = m * 1.2

Make m the subject

m = \frac{1500}{1.2}

m = 1250kg

<em>Hence, the mass of the vehicle is 1250kg</em>

Which of the following best describes the infrastructure ISPs provide?
svet-max [94.6K]

Answer:

cables, towers, and underground tubes

Explanation:

Its certainly the above one, and through this internet service is being provided. So internet service is self-understood, and what ISP firstly provides are cables, underground tubes, and the towers. And it is only these all through which the ISP provides internet service. And remember we are in this question dealing with the infrastructure and not the services or products. Hence, phone service, websites, and files, as well as the emails, search engines, and the videos, are not the solution here as they are not the infrastructure. And ISPs never provide the computers, ethernet cables or keyboards.

Hence, the correct answer is as mentioned in the answer section.
