Answer:
total number of electron in 1 litter is 3.34 × 
electron
Explanation:
given data
mass per mole = 18 g/mol
no of electron = 10
to find out
how many electron in 1 liter of water
solution
we know molecules per gram mole is 6.02 ×
molecules
no of moles is 1
so
total number of electron in water is = no of electron ×molecules per gram mole × no of moles
total number of electron in water is = 10 × 6.02 × × 1
total number of electron in water is = 6.02×
electron
and
we know
mass = density × volume ..........1
here we know density of water is 1000 kg/m
and volume = 1 litter = 1 × 
m³
mass of 1 litter = 1000 × 1 ×
mass = 1000 g
so
total number of electron in 1 litter = mass of 1 litter × 
total number of electron in 1 litter = 1000 × 
total number of electron in 1 litter is 3.34 × electron
The work done by the three students is 3,000 J.
The energy transferred in the process is 3,000 J.
<h3>What is work done?</h3>
- Work done is the product of force and distance moved by the object.
W = Fd
The work done by the three students is calculated as follows;
W = 300 x 10
W = 3,000 J
<h3>What is energy transfer?</h3>
- This is means by which energy is converted from one form to another.
The energy transferred in the process is determined by work energy theorem.
E = W
E = 3,000 J

Answer:
I didn't know these questions sorry
Answer: through digested food
Explanation: cells get their sugar molecules from the food that is taken in by an organism. The food taken in is digested by the stomach into base materials like sugar, fatty acids and amino acids. These base materials are circulated through the blood till they get to the cells where they are needed.
Answer:
2.5 N
because Average speed is equal to distance divided by time
