Planetesmals are made from

1 answer:

5 0

A planetesimal is an object formed from dust, rock, and other materials. According to the planetesimal hypothesis, when a planetary system is forming, there is a protoplanetary disk with materials from the nebulae from which the system came. This material is gradually pulled together by gravity to form small chunks.

An object with charge -4.0μC is placed between a positively charged object to the

elena-s [515]

The net force on the -4.0μC object as a result of this net field will be -10.4 N.

<h3>What is the charge?</h3>

The matter has an electric charge when it is exposed to an electromagnetic field is known as a charge.

The electric field intensity is found as the force per unit charge.

Electric field intensity on the positive charge:

$\rm E_1 = \frac{F_1}{Q} \\\\\ \rm 1.2 N/C = \frac{F_1}{ -4.0 \mu C} \\\\ F_1 = - 4.8 \ N$

Electric field intensity on the negative charge:

$\rm E_2 = \frac{F_2}{Q} \\\\\ \rm 1.4 \ N/C = \frac{F_1}{ -4.0 \mu C} \\\\ F_2 = - 5.6 \ N$

The net charge is the algebraic sum of the two charges;

$\rm F_{net}=F_1+F_2 \\\\ F_{net}= -4.8 -5.6 \\\\ F_{net}=-10.4 \ N$

Hence, as a result of this net field, the net force on the -4.0C object will be -10.4 N.

How are the strong winds associated with the tornado in diagram C product

Paul [167]

Answer:

there is no diagram, but i can try to help

Explanation:

strong winds bonding together (i.e hot and cold) help form the tornado, depending on the weather depends on how long it can go on, if more hot and cold are feeds into it, it will get faster and last longer. it is just like dust devils, it is wind and dirt mixing to make a tornado, the more wind and dirt the worst it will be
