Earth's subsystems are the geosphere, atmosphere, hydrosphere, and biosphere. Energy and matter are transferred when Earth's sub
systems interact.
Describe which of Earth's subsystems are involved when a hurricane passes through an area. Explain how these different subsystems affect one another.

Answer:
4. both blocks will both have the same amount of kinetic energy.
Explanation:
When the blocks are released free from the compression force, the spring exerts equal and opposite force on each block but the block with heavier (double) mass will attain slower ( half ) speed as compared to the lighter block according to the law of inertia. This works in synchronization to energy conservation.
Spring force is given as:
where: length of compression in the spring
<u>We know kinetic energy is given by:</u>
Hence the kinetic energy of both the blocks is equal when they are released to move free.
Answer:
the magnitude of the magnetic field is 8.704 x 10⁻⁴ T
Explanation:
Given;
potential difference, V = 278 V
radius of the circular path, r = 6.46 cm = 0.0646 m
charge of electron, q = 1.60218 × 10⁻¹⁹ C
mass of electron, m = 9.10939 × 10⁻³¹ kg
The magnitude of the magnetic field is given as;
where;
B is the magnitude of the magnetic field
is mass of the electron
v is velocity of the electron
r is the radius of the circular path
q is charge of the electron
Determine velocity of the electron from kinetic energy equation;
the magnitude of the magnetic field:
Therefore, the magnitude of the magnetic field is 8.704 x 10⁻⁴ T
