The best thing to do when an error message appears when it is not supposed to, as in if you are blocked by an administrator and it appears then its supposed to, it is best to contact someone who can investigate whether or not something is happening to your computer. That could be a parent, if they are good with computers, or just tech support at a store, provided they also know computers. Most of the time your computer just makes a mistake so nothing to worry about, but make sure to have it checked just to be sure.
Answer:
Effort = 120 Newton
Explanation:
Given the following data;
Mechanical advantage = 6
Load = 780 N
To find the effort required to lift the weight;
Mechanical advantage can be defined as the ratio of the load (weight) lifted by a simple machine to the effort (force) applied.
Mathematically, the mechanical advantage is given by the formula;
Making effort the subject of formula;
Substituting into the formula, we have;
Effort = 120 Newton.
Answer:
A modulator
Explanation:
This device is called a modulator and it does the task of modulation. The act of modulation influences data information on the carrier, allowing signal to be sent over a bandpass frequency range.
The Modulator is what controls an input audio signal which is called a carrier. It does not make a sound. What it does instead is to change the original carrier sound wave. The work of the Modulator as evident in the question is the conversion of information signal to a signal compatible with the medium over which it is going to be transmitted.
