The volume of a rectangular prism is given by the formula V = lwh, where l is the length of the prism, w is the width, and h is

Verizon [17]

For this case the volume of the box is given by:
 $V = lwh
$
 Substituting values we have:
 $V = (2a + 11) (5a - 12) (a + 6)
$
 Rewriting we have:
 $V = (10a ^ 2-24a + 55a-132) (a + 6)

V = 10a ^ 3-24a ^ 2 + 55a ^ 2-132a + 60a ^ 2-144a + 330a-792$
 Grouping terms of equal degree we have:
 $V = 10a ^ 3 + 60a ^ 2 -24a ^ 2 + 55a ^ 2 -132a -144a + 330a-792$
 Adding terms of equal degree we have:
 $V = 10 ^ 3 + 91a ^ 2 + 54a-792
$
 Answer:
the volume of the box is:
All the expressions given.

Calculate the centripetal force on the end of a 100 m (radius) wind turbine blade that is rotating at 0.5 rev/s. Assume the mass

Alja [10]

Answer:

3947.6 N

Explanation:

Centripetal Force: This is the force that tend to moves a body towards the center of a circle during circular motion.

The formula for centripetal force is

F = mω²r ........................ Equation 1

Where F = Centripetal force, ω = angular velocity, r = radius.

Where π = 3.1415

Given: m = 4 kg, ω = 0.5 rev/s = (0.5×2π) rad/s = 3.1415 rad/s, r = 100 m.

Substitute into equation 1

F = 4(3.1415)²(100)

F = 3947.6 N

Hence the centripetal force on the turbine blade = 3947.6 N
