Answer:
The ball will fall back and land to Elle's hands.
Explanation:
The bus move in a straight line with constant velocity means that there is no change of direction and no acceleration. Inertia can change the direction of the ball and acceleration can change its velocity. Since these two factors is not present in this scenario, the ball only has vertical movement. Thus the ball will land where it was thrown, in Elle's hands.
Correct Answer:
The ball will fall back to Elle's
B. Hibernation
C. Migration
D. Symbiosis
here is it answer.....
Because the lamp filament is physically very small and dissipates a relatively large amount of power (say, 60W for a typical incandescent bulb), while the conductors which feed it are relatively large and of negligible resistance, so they dissipate very little power, for a relatively large conductor area. How hot a component gets from resistive heating is proportional to its power dissipation, and inversely proportional to its area/size.
Thus if you dissipate, say 60W of power in a tiny lamp filament, it will get hot enough to become (surprise !!) incandescent, while the conductors which supply it (which dissipate perhaps a fraction of a watt for many feet of conductor length) will experience no significant temperature rise.
In fact, applicable electrical codes mandate that circuit conductors be sized large enough and provided with appropriate overcurrent protection, so that no significant conductor heating can take place.
Okay, let me reword this. Heat flows to areas that are cool, however, once the heated area begins to cool, the other area begins to warm up. Then there comes a point when there is no energy being transmitted into the two areas. When that happens the two areas obtain/are at the same temperature.
For example, you let the warm are escape your kitchen and go into the cold garage. You leave the kitchen door open and the heat continues to flow into the cold garage. After a while you will begin to notice that the kitchen feels noticeably cooler and the garage feels somewhat warmer. Then you wait a while longer and realize that both of the rooms feel like they are at the same temperature. They have then reached equilibrium.
A. 5
B. 3
C. 7
D. 4
Answer:
Option B
3
Explanation:
The two dimensions have the following significant numbers
4.56- 3 significant numbers
5.668- 4 significant figures
When responding, we give area as per the most precise number given hence the smallest (most precise) significant figures in these two numbers is 3. Therefore, the area will be given to 3 significant figures ie
4.56*5.668=25.84608 square meters
Area=25.8 square meters
