Answer:
they both exert the same pressure
Explanation:
Pressure is the ratio of force to area. It is given as:
, where F is the force, P is pressure and A is area
1) For the cuboid, the area of the base placed on the ground (A) = 8 cm × 3 cm = 24 cm² = 0.0024 m². Therefore the pressure is:
2) For the cube, the area of the base placed on the ground (A) = 4 cm × 4 cm = 16 cm² = 0.0016 m². Therefore the pressure is:
Therefore, they both exert the same pressure.
Answer:
Explanation:
mass, m = 1.25 kg
angular speed, ω = 235 rad/s
The moment of inertia of the cylinder is given by
I = 1/2 mr²
(a) the kinetic energy of rotation is given by
K = 1/2 Iω²
K = 1/4 mr²ω²
where, m is the mass of cylinder and r be the radius of cylinder
K = 0.25 x 1.25 x 0.32 x 0.32 x 235 x 235
K = 1767.2 J
(b) the kinetic energy of rotation is given by
K = 1/2 Iω²
K = 1/4 mr²ω²
where, m is the mass of cylinder and r be the radius of cylinder
K = 0.25 x 1.25 x 0.7 x 0.7 x 235 x 235
K = 8456.33 J
