What is the horizontal component of the

cat's displacement?

Answer in units of m

Technician A says the speeds at which two meshed gears turn depend on the number of teeth on each gear. Technician B says if the driving gear has fewer teeth than the driven gear, the speed of the driven gear increases. Who is correct?

A student creates a circuit that consists of a single battery and four resistors that are arranged as shown. How much energy is dissipated by the 2 Ω resistor after 120 s if the total current drawn from the battery is 5 A?

Why does a compass work differently on a moon then it would on earth

Suppose a car runs over a nail while driving at a speed of 54 miles per hour, and the nail is lodged in the tire tread 13 inches from the center of the wheel. what is the angular velocity of the nail in radians per hour?

Av citi auon A particle with velocity U = - 21 + 4 in meters per second at i = 0 undergoes a constant acceleration of magnitude a = 3ins - 2 at an angle O = 130° from the positive direction of the x axis.

The first law of thermodynamics states that ΔE = Q - W. Is this also a statement of the principle of conservation of energy? Yes, the heat added and the change in internal energy of the gas equal the work done by the piston.

How can we calculate the density of a sustance that has irregular volume

A two stage rocket leaves its launch pad moving vertically with an average acceleration of 4 m/s2. at 10 s after launch the first stage of the rocket (now without fuel) is released.

A liquid filled sealed system has cylinders with movable pistons on each end. The face of one piston has an area of 5 cm². The other piston has an area of 500 cm² and is supporting a weight of 2 kN on it.

A turntable is spinning on a frictionless axle when a ball of putty is dropped onto it from above. The putty sticks to the turntable when it lands. Is angular momentum conserved for the turntable and putty (the system) during this process?
