A yoyo toy is released from rest while the top of the string remains stationary. The mass of the toy is 0.081 kg, its radius is 0.053 m and its moment of inertia is 2.4 x 10-5 kg m2. What is the linear speed of the toy after it drops a height of 0.95 m

if the thermos has a vacuum innner, then heat through conv currents and conduction are reduced = vacuum flask

i need the answer to this too but idk it ; -;

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
