Answer:
Explanation:
Givens
d = 8.5 meters
vi = 0
a = 9.81
t = ?
Formula
d = vi * t + 1/2 a t^2
Solution
8.5 = 0 + 1/2 9.81 * t^2 multiply both sides by 2
8.5 = 4.095 t^2 Divide both sides by 4.095
8.5/4.095 = t^2
1.7329 = t^2 Take the square root of both sides
t = 1.316
It takes 1.316 seconds to hit the ground.

ff the mass of the block is too large and the block is too close to the left end of the bar (near string B) then the horizontal bar may become unstable (i.e., the bar may no longer remain horizontal). What is the smallest possible value of x such that the bar remains stable (call it xcritical)
. from the principle of moments which states that sum of clockwise moments must be equal to the sum of anticlockwise moments. aslo sum of upward forces is equal to sum of downward forces
smallest possible value of x such that the bar remains stable (call it xcritical)
∑τA = 0 = m2g(d− xcritical)− m1g( −d)
xcritical = d− m1
/m2
( L
/2−d)
If you're looking for the word it's heliocentric but if you're wondering what it is it's just where the sun is the center of the solar system and the planets all revolve around it.
Answer:
Extension of the wire is not indicated
Explanation:
Young modulus (YM)= (stress/Strain); Tensile Stress/tensile Strain
=> YM *Strain =Stress=F/A; A is cross sectional area and F is the force
(YM * Strain * A)/36 =F (Force developed in each wire)
F = (350 *e*0.0125)/12
