Specific gravity = Density of an object/Density of water
Density = Mass/Volume
For the current scenario;
Density of halite = mass/(l*w*h) = 58.75/(3.18*3.06*2.79) = 58.75/27.148932 = 2.164 g/cm^3
Density of water ≈ 1000 kg/m^3 = 1 g/cm^3
Therefore,
Specific density of halite = 2.164 g/cm^3 / 1 g/cm^3 = 2.164
The direction of force, when electric current and magnetic field direction given is at 90° to the plane containing current I and Magnetic field B.
<h3>What is magnetic force?</h3>
The force of attraction or repulsion experienced by a magnetic material when it enters the magnetic field.
When a wire with an electric current I is placed in a magnetic field of strength B it experiences a magnetic force F.
According to the Fleming's right hand rule, the direction can be determined by knowing any two parameter's direction.
Thus, The direction of force is at 90° to the plane containing current I and Magnetic field B.

The BT chemicals in the polymers of the UV radiation and asbestos
Answer:
a) 
b) 
c) 
Explanation:
a) In the equilibrium position of the system, that is when the spring is not elongated, the potential energy is zero. Therefore, the total energy of the system is the maximum kinetic energy:
b) The force constant of the spring can be calculated from the natural frequency of the system:
Recall that 
, that is the distance traveled in one revolution divided into the time of one revolution. Replacing and solving for k:
c) The maximum speed is directly proportional to the amplitude of the motion:
Satellites are placed into orbit at least 150 km above Earth's surface to be above the atmosphere.
