When a 26000-kg fighter airplane lands on the deck of the aircraft carrier, the carrier sinks 0.29 cm deeper into the water. Part A Determine the cross-sectional area of the carrier. Assume the density of seawater is 1025 kg/m3. Express your answer with the appropriate units.

What is the speed of an object at a given moment?

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 .

Asmall 12.00g plastic ball is suspended by a string in a uniform, horizontal electric field with a magnitude of 10^3 n/c. if the ball is in equilibrium when the string makes a 30 ° angle with the vertical, what is the net charge on the ball?
