Review
Listen
A constant potential difference is applied across a variable
resistor held at constant temperature. Which graph best
represents the relationship between the resistance of the
variable resistor and the current through it?

Which changes would result in a decrease in the gravitational force btween two objects? check all that apply

While the change in blank will remain the same during a collision, the force needed to bring an object to a stop can be blank if the time if collision is blank

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 .
