A 0.29 kgkg steel ball is tied to the end of a string and then whirled in a vertical circle at a constant speed vv. The length of the string is 0.62 mm, and the tension in the string when the ball is at the top of the circle is 4.0 NN. What is vv

some think that theories become laws, but theories and laws have separate and distinct roles in the scientific method. a law is a description of an observed phenomenon in the natural world that hold true every time it is tested. it doesn't explain why something is true; it just states that it is true.

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
