Answer:
R = 0.992 Ω
Explanation:
En esta pregunta, dada la información que contiene, debemos calcular la resistencia de la varilla de grafito.
Matemáticamente,
Resistencia = (resistividad * longitud) / Área De la pregunta;
Resistividad = 3,5 * 10 ^ -5 Ωm
longitud = 170 cm = 1,7 m
Área = 60 mm ^ 2 = 60/1000000 = 6 * 10 ^ -5 m ^ 2
Conectando estos valores a la ecuación anterior, tenemos;
Resistencia = (3.5 * 10 ^ -5 * 1.7) / (6 * 10 ^ -5) =
(3.5 * 1.7) / 6 = 0.992 Ω
Your mass stays the same because mass is the matter of something so the only way it could be changed is if you cut off something
Your weight changes because the gravitational field strength of different
Answer:
42.99°
Explanation:
= Kinetic friction force
= Pulling force at angle 
= Weight of the box = 150 N
Kinetic friction force

Pulling force at angle 

N = Pulling force
According to question

Applying Newton's second law in the vertical direction we get

The angle is 42.99°
