Answer: yes u can use a 6.75 when measuring the pencil
Answer:
Will experience a force due to electric field.
Explanation:
- When a free negative charge is released in an electric field it experiences a force due to the electric field in a direction opposite to the direction of the magnetic field.
According to Coulomb's law this force is mathematically given as:
and, electric field due to a charge is given as:
where:
permittivity of free space
q = magnitude of charge
r = radial distance from the charge
Answer:
Due to application of heat on a saturated solution, the interparticle space increases due to increase in the kinetic energy of the particles which allows more solutes to dissolve in the solution thereby making it unsaturated.
Mario Molina helped to bring about the 1987 Montreal Protocol on substances that result in depletion of the Ozone Layer.
<h3>What is ozone layer?</h3>
The topmost layer of the atmosphere which protect the harmful UV rays from the Sun to reach the Earth surface.
Mario Molina has the great contribution in science field. He tried hard and succeeded in passing an international agreement to eliminate CFCs also called as Chloro Fluoro Carbons and other ozone-depleting chemicals.
These CFCs were used in jet planes which depleted the ozone layer and a hole was observed over Antarctica.
