The charge density of the sheet is 1.384×10⁻⁷C/m².
Charge density is defined as the charge per unit area.
The sheet is a square of length l=17 cm.
Calculate the area A of the sheet .
The charge Q on the sheet is
The charge density σ is given by,
Substitute 4×10⁻⁹C for Q and 0.0289 m² for A.
Thus, the charge density of the sheet is <u>1.384×10⁻⁷C/m².</u>
Answer:
Explanation:
= Permittivity of free space = 
= Surface charge density = 
= 0.57-0.26
q = Charge = 
m = Mass of object = 
Electric field due to a sheet is given by
Electric field is given by
Voltage is given by
Kinetic energy is given by
The initial speed of the object is
Answer:
D) A warm front brings drizzly weather.
Explanation:
Luego de utilizar la fórmula del volumen de un líquido encontramos que si el acohol tiene 450 gramos entonces su volumen es de
La fórmula del volumen de la densidad de un líquido es la siguiente:
Densidad= Masa / Volumen
Volumen =Masa / Densidad
Es conocido que la densidad del alcohol es 789 kg/m³, y como sabemos por dato que tiene 450gr el siguiente paso es la sustitución:
Volumen=0.45/ 789
Volumen = 0,00057 m³
