There are many different touchscreens. Resistive, Capacitive, Infrared, Surface Acoustic Wave, Near field imaging, and Light pens. However, I am going to talk about Resistive, since that is the most popular in touchscreen technologies. They basically have a flexible upper layer of conducting polyester plastic bonded to a rigid lower layer of conducting glass and separated by an insulating membrane. When you touch the screen, you force the polyester to touch the glass and it will complete a circuit in the touchscreen. A chip inside will figure out where you touched the phone and send out an output.
Answer:
The answer is "Option b".
Explanation:
Logically, the replacement of rule is the rule of substitution that could only lead to a specific part of the logical expression, it is identical phrases will start replacing each other within the structure of valid logic.
- It is the probabilistic reasoning, replacement laws are applicable to manipulate initiatives.
- This rule of inference is being used only for the whole linear combination, that can be substituted by a rule of substitution.
You forgot your options, but I think i've seen this question somewhere already and i remember them. The answer is that it is not true that <span>Iron could be manufactured without the need to heat it up. </span>
<span>The impact of depicting slaves as being happy and good singers stereotyped all the other slaves and expecting them to showcase the same when they were being sold which gave them more pressure. Slaves then become not just house helpers but also entertainers which had its good and bad side effects.</span>
Answer:
F = 8.45 * 10^-8 N
Explanation:
The gravitational force is calculated using
F = GMm/r²
Where
G represent gravitational constant = 6.67 * 10^(-11)
M = Mass of the boy = 78kg
m = Mass of the girl = 65kg
r = Distance between them = 2m
Substitute these values in the formula, we have:
F = (6.67 * 10^(-11) * 78 * 65)/2²
F = (6.67 * 78 * 65 * 10^(-11))/4
F = (33816.9 * 10^(-11))/(4)
[Divide by the denominator]
F = 8454.225 *10^(-11)
[Expand]
F = 8.454225 * 10³ * 10^(-11)
F = 8.454225 * 10^(3-11)
F = 8.454225 * 10^-8
[Approximate]
F = 8.45 * 10^-8 N
Hence, the force of attraction between them is 8.45 * 10^-8 N
