Answer:
The net magnetic flux through the rest of Earth's surface is 
Explanation:
Given that,
Magnetic field = 42 μT
Area 

We need to calculate the flux per unit area

We need to calculate the total earth's surface area



We need to calculate the rest of earth's area

Put the value into the formula


We need to calculate the net magnetic flux through the rest of Earth's surface


Hence, The net magnetic flux through the rest of Earth's surface is 
Answer:
En el deporte, la persona que lo práctica tiene que adecuarse a él, por el contrario cuando hablamos de actividad física el objetivo pasa por programar, dosificar y adecuar en entrenamiento a las características, necesidades y objetivos de cada persona.
Answer:
See below
Explanation:
Find the NET forces on the objects
A 20==>
B 0
C 30==>
D 15==>
So biggest accel = C because it has the most force acting on it
next is A because it has the next biggest force
next is D then B ...B has no net force acting on it
Answer:
Explanation:
When a ray of light passes through denser medium to rarer medium and then after refraction it comes back into the denser medium, the phenomenon is called total internal refraction.
There are two necessary conditions for the total internal refraction.
(1) The refraction takes place g=from denser medium to rarer medium.
(2) The angle of incidence in the denser medium should be more than the critical angle for that pair of media.
