Acylinder of mass 6.0 kg rolls without slipping on a horizontal surface. at a certain instant its center of mass has a speed of 7.0 m/s. (a) determine the translational kinetic energy of its center of mass. j (b) determine the rotational kinetic energy about its center of mass. j (c) determine its total energy. j

(a) 147 j (b) 73.5 J (C) 220.5 J

Explanation:

Mass of the cylinder m =6 kg

velocity = 7 m/sec

(a) transnational energy

(b) Rotational kinetic energy is given by where I is moment of inertia and ω is the angular velocity

Moment of inertia

Putting the value of I in rotational kinetic energy formula

as v=ωr

So rotational kinetic energy

(c) Total energy = 147+73.5=220.5 j

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
