After landing on an unfamiliar planet, a space explorer constructs a simple pendulum of length 46.0cm. The explorer finds that the pendulum completes 105 full swing cycles in a time of 141s .
What is the magnitude of the gravitational acceleration on this planet?
What will be the equilibrium temperature while a 238 block of copper at 230 is placed in a 133 aluminium calorimeter cup containing 831 of water at 16.0.
A 2.20 kg object is suspended from a spring with k = 18.00 N/m. The mass is pulled 0.35 m downward from its equilibrium position and allowed to oscillate. What is the highest kinetic energy of object.
