Answer:
The total charge on the rod is 41.18 nC
Explanation:
Given;
length of glass rod, L = 10 cm = 0.1 m
radius of the rod, r = 4 cm = 0.04 m
Force of repulsion = 940 μN = 940 × 10⁻⁶ N
Charge on the bead = 6.5 nC = 6.5 × 10⁻⁹ C
Charge on the rod, Q = ?
From coulomb's law;
Where;
F is the force of repulsion in N
q₁ and q₂ are the charges on the bead and rod
R is the resultant distance between the two charges;
K is coulomb's constant = 8.99 x 10⁹ Nm²/C²
Therefore, the total charge on the rod is 41.18 nC
Answer:
the mass of the space ship would be greater than its mass when at rest, it's mass becomes so high that it reaches infinity.
Explanation:
From Einstein's relativity equation E=, where E is energy, m is mass and C is the speed of light, the equation shows that energy (E) and mass (m) are interchangeable because there are different forms of the same thing if mass is somehow converted into energy (just as in the atomic bomb). This equation shows that mass increases with speed (as an object moves, its mass increases), and if an object were to move close to the speed of light (the fastest speed a particle can move in a vacuum) its mass would increase that in reaches infinity.

Explanation: okay for question B its
The given statement is true.
<u>Explanation:</u>
Professional assessments are nothing but training a person to do or complete a work in a good and professional manner. Professional assessments are one kind of way to make the person or individual do all the respective work in a skillful and professional manner.
They are a reliable method to improve certain qualities of an individual and can be considered as the only main method to determine the health related fitness of an individual. There are no other health methods that can be used to determine the heath level of an individual. Hence the above provided statement can be concluded as true.
Answer:
Para que la masa del proton sea 1 kg se requieren alrededor de 6x10²⁶ protones.
Explanation:
Sabiendo que la masa del proton es:
Entonces para que la masa sea 1 kg tenemos:
En donde N es el número de protones.
Por lo tanto, para que la masa del proton sea 1 kg se requieren alrededor de 6x10²⁶ protones.
