Yes, friction is needed for a pen to work properly. When you apply pressure to the pen on a surface, the friction between the pen tip and the paper allows the ink to flow out smoothly, enabling you to write.
No, a pulley does not use friction. Pulleys are simple machines that use a wheel and axle to redirect the force applied to them. Friction is not necessary for a pulley to work properly.
No, velcro needs friction to function properly. The hooks and loops on velcro fasteners grip each other when pressed together, and this requires friction to create the necessary force for them to engage and hold together. Without friction, the hooks and loops would not interlock securely.
The formula for calculating the work done by friction is: Work Force of friction x Distance.
No, more friction does not necessarily mean more work. Friction is a force that resists motion, but work is defined as the product of force and displacement in the direction of the force. So, while friction can make it harder to do work in certain situations, they are not directly proportional.
Because without the friction on animals the the neutrons of the atoms would not be able to work properly.

No, We cannot do work on friction less surface
work is movement, and all movement causes friction, since there is no such thing as a "perfect" or "100% efficient" tool yet.
Lots of electronic items from America will work in Europe. You may need an adaptor to be able to plug them in as the voltage system is different. The television system is different, so some items may not work properly, like DVDs, as the region setting is different.

Unless you've been properly trained, electronic items can be dangerous to work on. Even if you unplug them and then work on them, if you don't put them back together correctly you could be harmed or start a fire when you plug them back in.
Friction's direction is always against the direction work is being applied to.
To calculate the work done by friction in a system, you can use the formula: Work Force of friction x Distance. First, determine the force of friction acting on the object. Then, multiply this force by the distance the object moves against the frictional force. This will give you the work done by friction in the system.
