Q

Substrate-level phosphorylation occurs in the cytoplasm of cells during glycolysis and in mitochondria during the Krebs cycle under both aerobic and anaerobic conditions. In the pay-off phase of glycolysis, a net of 2 ATP are produced by substrate-level phosphorylation.

A
• Angular Speed

Q

The hours hand rotates full circle in 12 hours. So it covers an angle 360⁰ in 12 hours. Minutes hand covers a full circle in 12 hrs.

angular velocity of hours hand = 2π/(12*3600) radians/sec
angular velocity of minutes hand = 2π/3600 radians / sec
so ratio = 12:1

A
• Motion in Plane

Q

a(centripetal) = v^2 / r = 25/10 = 2.5 m/s^2
a(tangential) = 2 m/s^2
a(net) = (2.5^2 + 2^2)^0.5
= (10.25)^0.5

A
• System of Particals and Rotational motion

Q

angural velocity(w) = v/r = 1/0.2 = 5 rad/s
Angular momentum = Iw + mv=0

A
• Motion in a Plane

Q

w= vxr Find the v perpendicular to radius vector which is vsin37. Since speed will remain same during landing. Thus, w = 10 x (3/5) = 6. Take care of the units
