They differ because they are transverse wave. That is their direction of travel is perpendicular to its vibrations.
Answer:
1) W = 150 J
Explanation:
Work (W) is defined as the product of force F by the distance (d)the body travels due to this force.
W= F*d Formula ( 1)
The work is positive (W+) if the force has the same direction of movement of the object.
The work is negative (W-) if the force has the opposite direction of the movement of the object.
The component of the force that performs work must be parallel to the displacement.
Work done to lift the floor box to its final position
We apply the formula (1)
W= F*d
W = (100 N)*(1.5 m)
W = 150 J
Answer:
65 years
Explanation:
The arc that ends at 4000 Hz intersects the 20 db hearing intensity at 65 years.
Answer:
work done by tension force on the twirled stone must be ZERO always
Explanation:
As we know that work done by a force on an object is given as


here we know that
= angle between force and displacement
now we know that tension in the string and displacement of the object is always perpendicular to each other when the rock is twirled in circular path.
so we can say for this motion of the stone

so work done by tension force on the twirled stone must be ZERO always
Increasing the separation distance between objects decreases the force of attraction or repulsion between the objects. And decreasing the separation distance between objects increases the force of attraction or repulsion between the objects. Electrical forces are extremely sensitive to distance.
