I think it’s C. Stroke if not then D
Answer:
Electronic tools provide accurate data
Explanation:
The sentence "Electronic tools provide accurate data analysis" is the only correct of all the options shown, because it is the only sentence that describes a characteristic present in all the electronic tools. The other options are not all electronic tools, but each option represents a type of electronic tool, depending on the time and technology used to build the tool.
Answer:
The energy is 
(a) is correct option
Explanation:
Given that,
Energy = 4480 j
Weight of nitrogen = 20 g
Boil temperature = 77 K
Pressure = 1 atm
We need to calculate the internal energy
Using first law of thermodynamics
Put the value into the formula
We need to calculate the number of molecules in 20 g N₂
Using formula of number of molecules
Put the value into the formula
We need to calculate the energy
Using formula of energy
Put the value into the formula
Hence, The energy is
The formula that will be used in this problem is E = q/ 4pi*r^2 z where z is the elctric charge constant equal to 8.854 *10 ^-12. The magnitude using r equal to 0.0525 m and q equal to -22.3 *10^-6 C is equal to -22.3 *10^-6/ 4pi*(0.0525)^2 *8.854 *10 ^-12 or equal to -7.272 *10 ^7. The magnitude 5 cm outside the surface is -22.3 *10^-6<span>/ 4pi*(0.0525+0.05)^2 *8.854 *10 ^-12 equal to -1.908 *10^7.

Answer:
force and surface area are two factors affecting pressure on solids
more the force you apply, more will be the pressure
pressure and force are directly proportional meaning if Force is greater, pressure will also be greater
more the surface area of the solid less will be the pressure
surface area and pressure are inversely proportional meaning if surface are is big, pressure will be less, surface area small, pressure will be greater
