Some basic forms of energy include light, heat, sound, electricity, and energy of motion, Energy has the ability to cause motion or create change. Every
day, we encounter objects in our environment that are in motion. Think about examples of objects in motion and how you would describe them.
Choose all true statements about objects in motion
An object moving in one direction can never begin moving in another direction
One way to determine if an object is in motion is by comparing it to the objects around it.
Some forces, such as pushes and pulls, can cause objects to move.
An object in motion will always move in one direction and cannot change directions
An object that is not changing its position is not in motion
Forces can make objects in motion change directions, but cannot cause objects to move

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 2.70 miss . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?

Atank has a shape of a cone with a radius at the top of 2 m and a height of 5 m. the tank also has a 1 m spout at the top of the tank. the tank is filled with water up to a height of 2 m. find the work needed to pump all the water out the top of the spout. (use 9.8 m/s2 for g and the fact that the density of water is 1000 kg/m3.)

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 .
