Answer:
for a mass m = 10kg on Earth it`s weight is W = mg = 10 x 10 = 100N.
Explanation:
Double the distance from the center and gravitational forces drop to 1/4 of what they were originally.
182.75 Newtons (about 41 pounds)
Answer:
FT = 103.15 N and T = 1.75 s
Explanation:
There are 3 forces at play here: gravity acting in vertical direction, tension from the string that makes 18 degrees with the vertical, and centripetal force generated by the circular motion which is horizontal.
Since the bob is moving at the constant speed, according to Newton 's 1st law the net force is 0. To find the tension force that makes a fixed angle of 18 degrees with the vertical, we can calculate that tension in the vertical direction and balance it with gravity force. Let g = 9.81m/s2
To calculate the centripetal force in the horizontal direction, we can calculate tension in the horizontal direction and balance it with the centripetal force
The centripetal acceleration a is
The radius of circular motion is:
The angular speed is
The time it would take to sweep 1 period, or 2π rad is
The correct option is C.
Since the home gets its water from public supply, the best place to get the water quality report is from the local water treatment facility who processed the water. Water quality report is a document which summarizes information about the water sources that are used, detected contaminants, compliance observed, etc.
