The only evidence you have that you exist as a self-aware being is your conscious experience of thinking about your existence. Beyond that you're on your own. You cannot access anyone else's conscious thoughts, so you will never know if they are self-aware.

- P is power
- R is resistance

Hence


- Therefore if power is low then resistance will be high.
The first bulb has less power hence it has greater filament resistance.
Gas or bubbles are formed
Heat, light, or sound is given off
Change in color
Different taste or smell (never taste or smell anything in a chemical lab, cause if u do bad reactions may occur to your body, unless directed to do so.)
New substance is formed (a precipitate)
<span>Temperature (exothermic or endothermic reactions) ( exothermic RELEASES heat energy) (endothermic ABSORBS energy)</span>
Answer:
110.25 J
Explanation:
We are given that
Mass,M=2.5 kg
Radius,R=0.5 m
Distance,d=4.5 m
Initial speed,u=0
We have to find the total kinetic energy
According to law of conservation of energy
Total kinetic energy=Potential energy=mgh
Where g=
Using the formula
Total kinetic energy=
Total kinetic energy
Answer:
In order to hit the same point with the second ball, you should throw it at an angle of 18° above the horizontal.
Explanation:
Horizontal reach formula for projectiles tells us

where
is the initial velocity and
the angle above the horizontal.
Since for both shots the reach must be the same, we have
.
