Answer is B.
In a lever, the effort arm is 2 times as a long as the load arm. The resultant force will be twice the applied force.
Hope it helped you.

The formula for accelerational displacement is at^2/2, so we know that 3.9t^2/2 = 200, or 3.9t^2 = 400. t =
, at = v, so
Answer:
11.72 mm
Explanation:
The gravitational potential energy equals the potential energy of the spring hence
where m is the mass of object, g is the acceleration due to gravity, h is the height, k is the spring constant and x is the extension of the spring
where \theta is the angle of inclination and d is the sliding distance
Making x the subject then
Substituting the given values then
Answer:
Explanation:
Partial Variation is a relation that is of the form y = mx+b. The graph of y = mx+b is a straight line with the slope of m and a y-intercept of b. ... The relation y = mx +b represents partial variation because the value of y varies partially with the value of x.
