90, since W=FxD so 30x3 is 90.

An object has a constant velocity of 20 m/s to the north, and there are two forces acting on it. What is this situation called
Llana [10]

When an object move with a constant velocity and there are forces acting on it, this is called unbalanced force. The forces acting on an object is a net force, which is capable of changing speed and/or direction of motion of an object. However, the two forces acting on the object can be added together to give the resultant force, which is a single force that has the same effect on the object as all the individual forces acting together.

Can anyone explain how to do this to me? It is due tomorrow at 9:30am. Thanks.
Georgia [21]
The 102N acting on the ropes being pulled by eric and kim have some of that force acting horizontally, and some of it vertically. By visualizing it as a right angled triangle, with the hypotenuse the length of the diagonal force, and each side the length of the horizontal and vertical forces, you can use trigonometry to calculate the length of the vertical force. You are told that it is at an angle of 30 with the vertical rope, therefore you know the length of the hypotenuse, and the angle between it and the vertical force, so using trig: (vertical force=x)
x/102=cos(30)
x=102*cos(30)
x=88.33
Therefore the diagonal ropes give a vertical force of 88.33N, and the centre rope, as it acts vertically, gives a vertical force of all 102N. The total:
88.33*2+102=278.66N

I don't know if this is very clear, I hope its good enough to help. If you don't understand, just ask, and I can answer any questions!!! :)

How does something become charged using friction?​
KonstantinChe [14]

<u>Answer:</u>

"Where friction or rubbing results in the transfer of electrons between particles, objects can become negatively or positively charged."

<u>Explanation:</u>

The motion resistance of one moving object with respect to another is called as "Friction". It isn't a basic force, like gravity or electromagnetism. Alternatively, scientists believe it is the product of the electromagnetic attraction in two touching surfaces between charged particles.

The friction have formula:  

Friction force (<em>f </em>)  = coefficient of friction  × normal force (N)

For an instances when one ride a bicycle, an example of rolling friction is the contact between the wheel and the way.
