The answer is (B. The study of Matter and Energy) but technically you could consider physics all of these as engineering is based on physics and that would be the study of inventions, chemistry and biology were both discovered because of physics, and physics invokes more math than any other subject as it applies math to the entire Universe.
<span>The earth has hotter summers and cooler winters because the axis of the earth is tilted. In July, the earth is tilted on its axis and is the furthest away from the sun while in January it is tilted so that it is closest to the sun at that time of year. That said, during the summer months, due to the way the earth is tilted, the sun's rays hit the earth at a much more direct line meaning they are more powerful. THis, in turn, makes the summer much warmer than the winter.</span>
The total number of lamps is mathematically given as
N=24
<h3>What is the t
otal number of
lamps?</h3>
Question Parameters:
How many 60-watt lamps could be connected in parallel on a 15-amp, 120-volt
Generally, the equation for the Power is mathematically given as
P=IV
Therefore
I=P/v
I=60/120
I=0.5A
Since the system does not exceed 80% of the rating
NI=I'(0.8)
N=15*0.8/0.5
N=24
In conclusion, the total number of lamps is
N=24

A) use v=u+at for both
First section, v=27, u=0, a=2.4. You should get 11seconds.
Second section, v=0, u=27, a=-1.3. You should get 21seconds.
This means that the total time is 22seconds.
b) You can either use s=ut+0.5at^2 or v^2=u^2+2as. Personally, I would use the second one as you are not relying on your previous answer.
First section, v=27, u=0, a=2.4. You should get 152m.
Second section, v=0, u=27, a=-1.3. You should get 280m.
This makes your overall displacement 432m.
