The answer is 167 pounds.
Answer:
Explanation:
Time to cover first 100 km = 1 hour.
time remaining = 3.15 - 1 = 2.15 hour .
Time to cover next 42 km = 1 hour .
Time remaining = 2.15-1 = 1.15 hour.
Distance to be covered = 310 - 142
= 168 km
least speed needed = distance remaining / time remaining
= 168 / 1.15
= 146.08 km / h .
Correct answer id option C that is tropical.
Tropical Climate is characterized by constant high temperature at sea level with an average temperature of 18°C or higher and is found near the equator.
Areas with tropical climate have high humidity and temperature. Countries in tropical region have high precipitation rate. Tropical climate is also known as equatorial climate. Tropical regions are found near equator. Due to high convection rate, there is abundant rainfall.
Answer:
d = 0.343 m
Explanation:
Given that,
The speed of a longitudinal wave, v = 343 m/s
Your ear is capable of differentiating sounds that arrive at the ear just 1.00 milliseconds apart.
We need to find the minimum distance between two speakers that produce sounds that arrive at noticeably different times.
Let the distance be d. So,
So, the required distance is equal to 0.343 m.
