.5mv^2 is the energy equation so .5(25kg)(5m/s)^2 so it’s 312.5 joules
Answer:
5 Pascal
Explanation:
Formula for pressure =
Plug in the numbers, it will be 25N divided by 5, whch is equal to 5 Pascal
Answer:
Hope this helps if not so sorry ;-;
Explanation:
Work is done when a force that is applied to an object moves that object. The work is calculated by multiplying the force by the amount of movement of an object (W = F *
Note:
Have a nice day :)
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
