The distance travelled is 10 m and the velocity gained at the end of this time is 2 m/s.
<h3>Velocity of the object at the end of the time</h3>
F = mv/t
where;
- m is mass of the object
- v is velocity of the object
- t is time
Ft = mv
v = Ft/m
v = (50 x 10)/250
v = 2 m/s
<h3>Distance traveled by the object</h3>
v² = u² + 2as
where;
u is initial velocity = 0
a is acceleration
a = F/m
a = 50 N/ 250 kg
a = 0.2 m/s²
v² = 0 + 2as
s = v²/2a
s = (2²)/(2 x 0.2)
s = 10 m
Thus, the distance travelled is 10 m and the velocity gained at the end of this time is 2 m/s.

Air that is not saturated will cool or heat at a rate of 10 degrees C/1000 meters as it rises or descends, respectively
The rate of the change in temperature which is observed while moving upward in the earth's atmosphere with elevation. It can be positive, negative and zero when the temperature decreases, increases or is constant with the elevation respectively.
For the atmosphere, the drop in temperature of rising air that is unsaturated air is about 10 degrees C/1000 meters (5.5 °F per 1000 feet) altitude.
That means if a there occur a rise of 1000 m , then the temperature of that thing will decrease to 10 degrees. Every 10°C of temperature from the given temperature will decrease at every rise of 1000 m .Air that is not saturated will cool or heat at a rate of 10 degrees C/1000 meters as it rises or descends, respectively

the layers of rocks, the ancient treasures that are at the bottom of the sea, how old the coral is. But I don't think they determined how old it is, how would the dinosaurs that lived in water swim or any drink water. I don't know if this helps but hopefully it does. Also scientist have made advanced tech that could help with the age determination of the ocean floor.
6 chairs will fit across the platform.
<h3>Calculation</h3>
We have a school stage of 8 3/4 feet wide.
It's also given that each chair is 1 5/12 feet wide.
To find out the number of chairs possible we can simply divide the total length available by width of the chair.
8 3/4 = 35/4
1 5/12 =17/12
So, 35/4 / 17/12
So, the final answer comes up to 6.
so, the total number of chairs that would fit in are 6.

Answer:
32.176 ft/s²
9.807 m/s²
Explanation:
Data provided in the question:
Acceleration of the free falling object = 78979.4 mi/hr²
a) In ft/s
Now,
1 mi = 5280 foot
and,
1 hour = 3600 seconds
thus,
78979.4 mi/hr = 
or
78979.4 mi/hr = 32.176 ft/s² ...............(1)
b) In m/s²
Now,
1 foot = 0.3048 m
thus,
we have from 1
32.17 ft/s² = 
or
78979.4 mi/hr = 32.176 ft/s² = 9.807 m/s²
