Answer:i

9E13 ELECTRONS

Explanation:

First we find the number of charges in two hrs

Which is - 2x 7200=- 14400NC

So no of electrons is now q/e

-144x10^-7/-1.6*10^-19

= 9*10^13

A 1.6-cm-thick wood floor covers a 4.0m×5.5m room. Part A The subfloor on which the flooring sits is at a temperature of 16.1 ∘C

Bogdan [553]

Answer:

Rate of heat conduction will be 935 Watt

Explanation:

We have given thickness of the floor d = 1.6 cm = 0.016 m

Area $A=4\times 5.5=22m^2$

Temperature difference $\Delta T=19.5-16.1=3.4^{\circ}C$

Thermal conductivity of the wood k = 0.200 w/M-K

We have to find heat conduction

Heat conduction is given by $\frac{Q}{t}=\frac{kA\Delta T}{d}=\frac{0.200\times 22\times 3.4}{0.016}=935Watt$

Rate of heat conduction will be 935 Watt

a) The student hypothesizes that a greater fraction of kinetic energy is lost from the system during the collision when the spee

Mashcka [7]

Answer with Explanation:

One hypothesis above would probably rely on the situation called "inelastic collision." The two carts are travelling towards each other at different speed. So, this means that once they collide, the kinetic energy will not be conserved but will be transferred as sound energy, thermal energy or material deformation. The impact will be great, thus a greater fraction of kinetic energy will be lost from the system.
