Answer:
The material through which sound is travelling
Explanation:
Solid has compact molecules so sound waves can moove easily and fastly.
In case of liquid, it has relatively less inter- molecular space so, sound transfers slowly..
Hope you can generate meaning regarding spped of sound in gas...
MAKE ME BRAINLIST PLEASE...
I know the process but I don't know the heat capacity of tea.. so I can't show you the process untill you give me tea's heat capacity
Thrust - Friction = mass * acceleration
Friction = coefficient * mass * gravity
Friction = 0.10 * 75 * 9.8 = 73.5 N
Substituting:
200N - 73.5 = 75a
a = 1.69 m/s^2
Obtaining final velocity at the end of 41 seconds:
Vf = at
Vf = 1.69 (41)
Vf = 69.15 m/s
Using the formula for displacement for linear motion problems:
s = Vo*t + (1/2)a*t^2
s = 0 + (1/2)(1.69)(41^2)
s = 1420.445 meters
After he runs out of fuel, we use the following formula to find the distance that he coasts:
F = ma = coefficient*m*g
a = 0.10(9.8)
a = -0.98
Vf^2 = Vo^2 + 2as
0 = 69.15^2 + 2(-0.98)s
s = 2439. 65
Adding the 2 displacements together to obtain the total distance:
Total distance = 2439.65 + <span>1420.45 meters
Total distance = 3860.1 meters</span>
Answer:
17.2 meters
Explanation:
Carbon dioxide (CO2) molecular mass is 44g/mol, then the number of moles of 10000kg carbon dioxide will be:
10,000kg * (1000g/kg)/ (44g/mol) = 227,272moles
The volume of gas in STP is 22.4 L/mol, then the volume of the carbon dioxide will be:
227,272 moles* 22.4L/mol= 5,090,909 L
One liter equal to 0.001 meter cubic. The formula for cube volume is , if the volume is 5090909L then the side of the cube will be:
volume=
5090909L * (0.001 /L)=
side=
side= 17.2m
-is made mostly of hydrogen and helium.
-will eventually run out of fuel and die.
-creates energy through nuclear reactions
