Answer:
6 seconds distance
Explanation:
When driving during inclement weather conditions such as heavy rainfall, snowfalls, etc.The minimum following distance must be increased to 6 sec distance. Moreover, during severe weather conditions the following distance must further be increased to a 10 seconds distance.
Crossed electric field lines indicate A) a field pointing in two directions
Substances that move to the stronger parts of a magnetic field are termed paramagnetic substances; the atomic feature responsible for this property is presence of unpaired electrons in atoms.
<h3>What is a paramagnetic substance?</h3>
A paramagnetic substance is the substance that possess unpaired electrons that are heavily attracted in a magnetic field.
A magnetic field is defined as the field that exists around a magnet that produces a field of force.
Examples of paramagnetic substance include the following:
- aluminum,
- gold,
- copper.
- Chromium, and
- Manganese.
These substances are known as paramagnetic substances because they possess a high number of unpaired electrons.
Other properties of a paramagnetic substance include the following:
- They have a permanent dipole moment or permanent magnetic moment.
- They are weakly magnetized in the direction of the magnetizing field.
- They usually have constant relative permeability (μr) slightly greater than 1.
Therefore, Substances that move to the stronger parts of a magnetic field are termed paramagnetic substances; the atomic feature responsible for this property is presence of unpaired electrons in atoms.

Answer:
The gravitational potential energy (PE) of a particle or a system of particles is a form of energy that exists due to its position. Mathematically, it is expressed as the product of mass, gravitational acceleration, and the vertical displacement.
Explanation:
Given data:
Mass of the storage box, 
Height, 
The gravitational potential energy of the storage box can be expressed as,
