A sphere of mass m and radius r is on a smooth fixed inclined plane in equilibrium, if now the sphere is displaced by a small distance along the plane , what will be angular frequency of the resulting SHM (k=4M/3)( angle of inclination =30 degree)
Ans) 2pie(3/4)1/2
Does weight affect how far you jump? For the same leg strength / jumping method, weight affects how far one can jump. Acceleration = Force / Mass With more mass, you can
The stress at which the specimen breaks or reptures ultimately is known as ultimate strength. We also called this TENSILE STRENGTH .

A well-insulated electric water heater warms 109 kg of water from 20.0°C to 49.0°C in 25.0 min. Find the resistance of its heating element, which is connected across a 240-V potent
Total height of the gymnast just before falling back down is=(2+.3)=2.3m Energy gained at that point = m*g*h(m=mass, g=gravitational force, h=height) =55*9.8*2.3=1239.7 J
