a system absorbs 35J of heat and in the process it does 11J of work if the initial internal energy is 205J a, what is the final internal energy b, the system follows a different thermodynamic path to the same final state and does 15J of work, what is the heat transferred ?

The image shows a pendulum in simple harmonic motion the pendulum starts at a and swing to e

It's a snowy day and you're pulling a friend along a level road on a sled. you've both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. you've been walking at a steady 1.5m/s, and the rope pulls up on the sled at a 32 ∘ angle. you estimate that the mass of the sled, with your friend on it, is 65 kg and that you're pulling with a force of 80 n .
