Answer:

a. Jupiter

Explanation:

The Great Red Spot is the largest anticyclonic vortex in the solar system. It is a great whirlpool that could exist for more than 300 years, since it is believed that observations in the 17th century are from the same storm, it is characterized by winds on its periphery of up to 400. $\frac{km}{h}$

The distance between two particles is 2 centimeters. If the distance is increased to 4 centimeters, the force will be ?

postnew [5]

Answer:

The new force is 1/4 of the previous force.

Explanation:

Given

$Initial\ Distance = 2cm$ ---- $r_1$

$New\ Distance = 4cm$ --- $r_2$

Required

Determine the new force

Let the two particles be q1 and q2.

The initial force F1 is:

$F_1 = \frac{kq_1q_2}{r_1^2}$ --- Coulomb's law

Substitute 2 for r1

$F_1 = \frac{kq_1q_2}{2^2}$

$F_1 = \frac{kq_1q_2}{4}$

The new force (F2) is

$F_2 = \frac{kq_1q_2}{r_2^2}$

Substitute 4 for r2

$F_2 = \frac{kq_1q_2}{4^2}$

$F_2 = \frac{kq_1q_2}{4*4}$

$F_2 = \frac{1}{4}*\frac{kq_1q_2}{4}$

Substitute $F_1 = \frac{kq_1q_2}{4}$

$F_2 = \frac{1}{4}*F_1$

$F_2 = \frac{F_1}{4}$

The new force is 1/4 of the previous force.

A person whose weight is 5.20 3 102 N is being pulled up vertically by a rope from the bottom of a cave that is 35.1 m deep. The

kodGreya [7K]

Answer:

It is given that the weight of the person is 102 N

We have the force that shall be needed to being the man out in minimum amount of time shall correspond to the maximum tension that can be developed

Thus using Newton's second law we obtain the acceleration that the man shall attain

$\sum F_{ext}=m\overrightarrow{a}\\\\T-W=ma\\\\\therefore a=\frac{T_{max}-W}{\frac{W}{g}}\\\\a_{max}=\frac{569-102}{\frac{102}{9.81}}=44.9m/s^{2}$

Now using second equation of kinematics to obtain time 't' we get

$t=\sqrt{\frac{2s}{g}}\\\\t=\sqrt{\frac{2\times 35.1}{44.9}}=1.25secs$
