Answer:
the time required for one half of a sample of a radioisotope to decay
Answer:
C4H7OH + 6O2 => 4CO2 + 4H2O
Explanation:
hope This helps :)
Osmotic pressure is the pressure that would have to be applied to a pure solvent to prevent it from passing into a given solution by osmosis.
That can be mathematical computed from the expression:
Osmotic pressure=C×R×T
Where,
C= Concentration
R=Gas constant
T=Temperature
Concentration=Number of moles of solute/Volume(L)
=0.005*1000/100
=0.05
R= 0.08206 atm L/mol K
T=25+273
=298
Osmotic pressure= 0.05×0.08206×298
=1.2 atm
Answer:
The potential energy is 9800 J.
Explanation:
given information:
mass, m = 50 kg
height, h = 20 m
to calculate the potential energy, we can use the following formula
PE = mgh
where
PE = potential energy (Joule)
m = mass (kg)
h = height (m)
g = gravitational constant (9.8 m/s²)
so,
PE = mgh
= 50 x 9.8 x 20
= 9800 J
