Answer:
Explanation:
Catalytic converters are used as an exhaust emission control device and are used to remove toxic gases and products by catalyzing the redox reactions.
The Corporate Average Fuel Efficiency (CAFE) standards were set of rules enacted in the USA to increase the efficiency of fuel engines and hence to reduce the emission rates .
The ethanol as compared to the conventional gasoline emits 50 per cent or lesser greenhouse gases to the environment .
False ! Taj Mahal was built in the memory of Mumtaj Mahal, who was the wife of Shah Jahan ! he loves her a lot, and thus makes Taj Mahal in her memory !
I am from India , and I know how it feels and look like , the love in the Taj !
We can solve this problem, if we use the rule of three.
x=the actual distance between these towns
1 cm----------------78 Km
3 cm---------------- x
1cm *x=3 cm * 78 Km
x=(3 cm * 78 Km) / 1cm=234 Km
Solution: 234 Km
Answer: a. perigee speed
Explanation:
Firstly, we must define what is Perigee and Apogee:
The apogee is the point in an elliptical orbit around the Earth <u>where a body is furthest from the center of it and according to Kepler's 2nd law the speed of a satellite at this point is the lowest.
</u>
On the other hand, the <u>perigee</u> is the opposite orbital point. <u>It is where a satellite is closest to Earth and its orbital speed is maximum.
</u>
Therefore, if we want to throw an object in such a way that it is orbiting the Earth at the same distance respect to the ground, the minimum speed must be that which is in the perigee.
