Answer:
Explanation:
<em>Diesel engines burn as much as 30% less fuel than gasoline engines of comparable size, as well as emitting far less carbon dioxide gas and far fewer of the other gasses that have been implicated in global warming.

<em>
</em>
<em>(B) of comparable size, as well as emit far less carbon dioxide gas and far fewer of the other gasses having

<em>
</em>
<em>(C) of comparable size, and also they emit far fewer carbon dioxide and other gasses that have
</em>
<em>
</em>
<em>(D) that have a comparable size, and also they emit far fewer of the other gasses having
</em>
<em>
</em>
<em>(E) that have a comparable size, as well as emitting far fewer of the other gasses having</em>
<em>A is the most appropriate statement above. Diesel engine consume less energy and release fewer gases than the gasoline engines .</em>
<em>Both engine(Diesel and gasoline) converts chemical energy to electrical energy.</em>
Answer:
m = 4.4 × 10³ kg
Explanation:
Given that:
The total yearly energy is 4.0 × 10²⁰ J
The amount of mass that provides this energy can be determined by using the formula:
E = mc²
where;
c = speed of light in free space = (3 × 10⁸)
4.0 × 10²⁰ = m × (3 × 10⁸)²
![m = \dfrac{4.0 \times 10^{20} }{(3\times 10^8)^2}](https://tex.z-dn.net/?f=m%20%3D%20%5Cdfrac%7B4.0%20%5Ctimes%2010%5E%7B20%7D%20%7D%7B%283%5Ctimes%2010%5E8%29%5E2%7D)
m = 4.4 × 10³ kg

I think that golf courses call in the golfers if there is a lightning strike within 5 miles of the golf course sensor.
Answer:
24 kg m/s
Explanation:
The change in momentum of the wrench is given by:
![\Delta p = p_f - p_i](https://tex.z-dn.net/?f=%5CDelta%20p%20%3D%20p_f%20-%20p_i)
where
is its final momentum
is its initial momentum
At the beginning, the wrench is at rest together with the astronaut, so its momentum is zero:
![p_i = 0](https://tex.z-dn.net/?f=p_i%20%3D%200)
After it is launched, its momentum becomes
![p_f = m v](https://tex.z-dn.net/?f=p_f%20%3D%20m%20v)
where
m = 2.0 kg is its mass
v = 12 m/s is its velocity (taking the direction of the wrench motion as positive)
Substituting,
![p_f = (2.0)(12)=24.0 kg m/s](https://tex.z-dn.net/?f=p_f%20%3D%20%282.0%29%2812%29%3D24.0%20kg%20m%2Fs)
So, the wrench's change in momentum is
![\Delta p = p_f - p_i = 24-0=24 kg m/s](https://tex.z-dn.net/?f=%5CDelta%20p%20%3D%20p_f%20-%20p_i%20%3D%2024-0%3D24%20kg%20m%2Fs)
