<span>This can be explained by the effect of a material-specific parameter called Thermal conductivity. How well a material conducts heat is called Thermal conductivity. Metal has a greater thermal conductivity co-efficient and hence conducts heat very well Cardboard, on the other hand, is a very poor heat conductor. C</span>ardboard is composed of cellulose, a polymer that has no free electrons. Without <span>free electrons materials can neither conduct electricity or heat efficiently.</span>
Answer:
I don't know about the 1st one but An object at rest stays at rest and an object in motion stays in motion at a constant speed and direction unless acted upon by an unbalanced force. Or maybe its moving because the earth is moving and gravity is pulling it with.
2. Speed is the rate at which something or someone is able to move. Instantaneous Speed - the speed at any given instant in time. Average Speed - the average of all instantaneous speeds; found simply by a distance/time ratio.
3. Speed = distance divided by time or
. Some units for speed can be miles, kilometres, feet, or metres.
4. Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement. Put another way, speed is a scalar value, while velocity is a vector.
XA = PA/PA^0
XA = 22.98/23.76 = 0.9671
0.9671 : 0.0328
bi = ni/msolvent
0.9672 * 18.015/1 mol = 17.42 g H2O
bi = 0.0328 mol urea/17.42 g H2O * 1000
bi = 1.88 m
hope this helps
Answer:
12.267 seconds approximately.
Explanation:
The units can be simplified into m/s, in which case you would have 61000/3600. Simplify that to 16 and 17/18. This is your meters per second, so multiply that by .724 to get the answer.
