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 with Explanation:
We are given that
a.Linear acceleration,a=0.1 g
Moment of inertia of solid sphere,
We know that
Using the formula
b.When a frictionless block were to slide down the incline at that angle then the motion of block will be linear .There is no rotation.
When the sphere is moving without rotation then, the linear speed of sphere will be larger.
When the linear speed is larger then, the linear acceleration will be larger.
Hence, the magnitude of acceleration will be more.
