A net force on a 2 kg cart accelerate the cart at 6 m/s2. How much acceleration would the same net force produce on a cart that is 7 kg? Explain.

Zeros that follow non-zeros numbers and are also to the right of a decimal point are significant

Consider the growth of a 20-nm-diameter silicon nanowire onto a silicon wafer. the temperature of the wafer surface is maintained at 2400 k. assume the thermal conductivity of the silicon nanowire is 20 wm-1k-1 and all its surfaces including the tip are subjected to convection heat transfer with the coefficient h = 1×105 wm-2k-1 and t∞ = 8000 k. when the nanowire grows to l = 300 nm, what is the temperature of the nanowire tip (t (x =
