You hold a ruler that has a charge on its tip 5.00 cm above a small piece of tissue paper to see if it can be picked up. the ruler has -10.0 hc of charge. the tissue paper has 3.00 g of mass. what is the minimum charge required to pick up the tissue paper? what forces act on the tissue paper? how does newton's second law apply to the forces? which force can be related to the charges?

Figure 9 on page 362 shows various motions of balls. the curved path followed by the yellow ball in b in picture b is result of a) inertia b) centripetal motion c) gravity and horizontal velocity d) linear motion

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 .
