The solute would then sink to the bottom and would not dissolve
Well other planets have a gravitational pull that's what keep the planet's orbiting the sun. But the amount of gravity differs by mass.
Hope this helps :)

FOR PARALLEL CONNECTION</h3><h3>I1 = 0.12A</h3><h3>I2 = 0.12A </h3><h3>IT =0.24A</h3><h3>FOR SERIES CONNECTION</h3><h3>I1 = I2 = 0.06A</h3><h3>IT =0.06A</h3><h3 />
Explanation:
According to ohms law, V =ITRt
V is the supply voltage
IT is the total current flowing in the circuit
Rt is the total equivalent resistance
Given R1= R2= 100Ω
V= 12V
FOR PARALLEL CONNECTION;
To calculate the total current IT in the battery, we need to calculate the total equivalent resistance RT first. For a parallel connected circuit, the equivalent resistance in the circuit is the sum of the reciprocal of its individual resistances as shown;
RT = 50Ω
from the equation above;
IT = V/RT
IT = 12/50
IT = 0.24A
Note that in a parallel connected circuit, different current flows through the resistances but the same voltage is across them.
IT = I1+I2
For current in resistance R1;
I1 = V/R1
I1 = 12/100
I1 = 0.12A
Since both resitance are the same, they will share the total current equally. Therefore I2 = 0.12A
FOR SERIES CONNECTION;
The total equivalent resistance in the circuit will be the sum of their individual resistances.
RT = 100Ω+100Ω
RT = 200Ω
IT = V/RT
IT = 12/200
IT = 0.06A
Since the resistances are connected in series, the same current will flow through them but different voltages. The total current flowing in the circuit will be the same current flowing through the resistors.
Therefore I1 = I2 = 0.06A
Daniel applies a 30 Newtons force on the ball that sends the ball 300 meters, which gives the work done by Daniel as 9 kJ
<h3>How can the work done be obtained from the given force and distance?</h3>
The given parameters are;
The force with which Daniel hit the ball = 30 Newtons
The distance the ball flew, following the application of the force = 300 meters
Required;
The amount of work done on the ball by Daniel
Solution:
- Work done = Force applied × Distance moved in the direction of the force
Therefore;
The work done by Daniel on the ball, <em>W</em>, can be calculated as follows;
W = 30 N × 300 m = 9000 J = 9 kJ
- The work done by Daniel on the ball is 9 kJ
