What are the options for A,B,C,D? There’s arrows
Answer:
time is 0.5660 s
and time is - 3.62431 s
Explanation:
velocity u = 15 m/s
height s = 10 m
acceleration due to gravity g = –9.8 m/s²
to find out
time
solution
we will apply here distance equation that is
s = ut - 1/2× gt² ...........1
here put all these value and get time t
here s is height and g is -9.8
so
s = ut - 1/2× gt²
10 = 15t - 1/2× (-9.8)t²
10 = 15t + 4.9t²
solve it we get t
t = 0.56630 and -3.62431
so time is 0.5660 s
and time is - 3.62431 s
Answer:
The Wind Missouri-Mississippi, The Snake Columbia, and the Green-Colorado drainage.
Explanation:
- The wind river ranges of the Wyoming is a major headwaters system of the united states and the rage is home to about 63 glaciers and ten of the largest glacier of the united states are found in this region. The wind river range is about 77% of the area s located in the drainage.
- The green river is located in the western united states and forms a green river basin of about 730 miles long and covers much of the Colorado plateaus and the snake river forms in a major area of the Sierra Nevada and the cascade range.

The work done by a gas is given by:
where
p is the gas pressure
is the change in volume of the gas
In this problem,
(atmospheric pressure)
is the change in volume
So, the work done is
2. 10170 J
The amount of heat added to the water to completely boil it is equal to the latent heat of vaporization:
where
m is the mass of the water
is the specific latent heat of vaporization
The initial volume of water is
and the water density is
So the water mass is
So, the amount of heat added to the water is
Answer:
B
Explanation:
B, because if u subtract the forces from each other the forward one outweights the other ones
