A box with a mass of 22.0 lg is placed on a ramp that is at 38.0 degrees above the horizaontal. Find the weight (Fg) of the box in N. Find the perpendicular force (Fgv) in N. Find the parallel force (Fgx) in N. Find the accreditation of the box in m/s^2. All answers should be in 3 SIG. FIG.

I’ve been stuck on this for a while

Along wire of diameter 1 mm is submerged in an oil bath of temperature ∞ 31°c. the wire has an electrical resistance per unit length of 0.01 ω/m. if a current of 103 a flows through the wire and the convection coefficient is 500 w/m2·k, what is the steady-state temperature of the wire? from the time the current is applied, how long does it take for the wire to reach a temperature that is within 1°c of the steady-state value? the properties of the wire are 8000 kg/m3, 500 j/kg·k, and 20 w/m·k.

The reason a penny thrown straight up inside a bus will come back to your hand is that you,the bus,the air inside the bus, and the penny are all moving at the same velocity. true or false
