The buoyant force on an object submerged in a fluid is equal to the density of the fluid it displaces.
According to Archimedes' principle, the magnitude of the buoyant force is equal to the weight of the fluid displaced by the object. The weight of the displaced fluid is directly proportional to the volume of the fluid displaced and the density of the fluid. So, the buoyant force (B) can be mathematically represented as:
B = ρ * V * g
Where:
ρ (rho) is the density of the fluid,
V is the volume of the fluid displaced by the object, and
g is the acceleration due to gravity.
The key point to remember is that the buoyant force acts in the opposite direction to gravity. If the object's weight is less than the buoyant force, it will float; if it is greater, it will sink.

equilibrium position. What is the spring constant
of this spring?
(1) 9.36 N/m (3) 37.4 N/m
(2) 18.7 N/m (4) 74.9 N/m
The correct answer to the question is: 4) 74.9 N/m.
EXPLANATION:
As per the question, the stretched length of the spring is given as x = 0.250 m.
The potential energy gained by the spring is given as 2.34 joules.
We are asked to calculate the spring constant of the spring.
The potential energy gained by the spring is nothing else than the elastic potential energy .
The elastic potential energy of the spring is calculated as -
Potential energy P.E =
⇒k =
=
= 74.88 N/m
= 74.9 N/m. [ans]
Hence, the force constant of the spring is 74.9 N/m.
B) increase in severity of hurricanes
C) long-term electrical power generation
D) improvement in satellite communication
Solar prominences themselves are of no concern because they are visible in the Hydrogen Alpha wavelength. They are anchored in place by magnetic fields. When these fields break or reconnect, it can send the plasma that makes up the prominence away from the sun. If one of these clouds impacts Earth, they are called CMEs or coronal mass ejections. Depending on the magnetic orientation of the cloud with respect to Earth's the CME can break down our magnetic field resulting in geomagnetic storms, aurorae, power grid fluctuations, and particle radiation near the poles, satellite single upset events, and radio blackouts.
Thus, letter a is the answer.
