Atmospheric pressure decreases with the increase in altitude.
hope that helps you!
Answer:
Explanation:
First of all let's define the specific molar heat capacity.
(1)
Where:
Q is the released heat by the system
n is the number of moles
ΔT is the difference of temperature of the system
Now, we can find n with the molar mass (M) the mass of the compound (m).
Using (1) we have:

The answer is D. The input force is equal to the output force.
I just did test and got it right
Answer:
A.) Time = 0.625 hrs = 37.5 minutes
B.) Speed required = 133.33km/hr
Explanation:
Given the following :
Total race distance = 100km
Total time required = 1 hour = 60 minutes
Average speed after traveling 50km = 80km/hr
80km/hr : This means it will take one hour to cover a distance of 80km
Therefore, time taken to cove first 50km at that average speed equals :
1 hour = 80 km
t hours = 50km
80t = 50
t = 50/80
t = 5/8 hours
t = 0.625hours
t = 0.625 * 60 = 37.5minutes
B)
Average speed required to complete the race in 1 hour = 100km/hr
Time used to complete first 50km = 0.625 hour
Time remaining: (1 - 0.625) hour = 0.375
Speed required = Distance left / time left
Speed required = 50 / 0.375
Speed required = 133.33km/hr
Answer:
4.93 m
Explanation:
According to the question, the computation of the height is shown below:
But before that first we need to find out the speed which is shown below:
As we know that
= 9.92 m/s
Now
98.4064 = 19.96 × height
So, the height is 4.93 m
We simply applied the above formulas so that the height i.e H could arrive
