Answer:
133.62 kmh.
Explanation:
Time provided = 3.25 hours.
Distance to be covered 300 km
Times spent in first 100 km = 1 hour
Time spent in next 43 km
= 43 / 40 = 1.075 hours
Total time spent = 2.075 hours
Total distance covered = 143 km
Distance remaining = 300 - 143
=157 km .
Time remaining = 3.25 - 2.075
= 1.175
Speed required = Distance remaining / time remaining
= 157 / 1.175
= 133.62 kmh.
Answer:
The correct answer is: 0°C + 0°C = 32°F
Explanation:
We need to remember the conversion equation from Celsius to Fahrenheit:
In our case x = 0, then y will be:
Now 0°C + 0°C is just 0°C because if we add a body at a certain temperature to another body with the same temperature the total temperature will the same.
Then, knowing that 0°C = 32°F we can conclude that:

Answer:
Extrasolar planets are very dim light sources compared to their stars. At visible wavelengths, they generally have less than a millionth of the brightness of their parent star. It is extremely difficult to detect this type of dim light source, and in addition, the parent star has dazzling light that almost makes it impossible.
Answer:
a) 
b)
