Answer:
The combinations are
1. C ,
2. C ,
Explanation:
The force between two charges q and Q is given by Coulomb's law.
The coulomb force is given by
Where, r be the distance between two charges
According to the question,
r = 15 cm, Q = C, q = C , F = 12 N
Force remains same, distance remains same
so the product of Q and q be same
The product of Q and q is
So other combination of charges are
1. C ,
2. C ,
The statement that is true regarding a distance vs. time graph is option A: The graph should show distance on the vertical axis.
<h3>Where is the plot of distance?</h3>
How far an object has come in a certain amount of time is displayed on a distance-time graph. Time is represented on the X-axis and Distance is plotted on the Y-axis (left) (bottom).
On a distance-time graph, an object's motion is indicated by a sloping line. The slope or gradient of the line in a distance-time graph is equal to the object's speed. The object is travelling more quickly the steeper the line is (and the bigger the gradient).
Note that the distance-time graph shows the relationship between distance and time by plotting distance on the y-axis and time on the x-axis.

Answer:
Newton's third law of motion.
Explanation:
We are told the force needed to throw the full soda can was more than that needed to throw the empty can.
Now, the weight of the full soda can will be more than that of the empty can. Therefore, the full can will demand more force than that of the empty can due to Newton's third law of motion which states that to every action, there is an equal and opposite reaction.
Answer:
The height of the squirrel
Explanation:
From the question we are told that
The horizontally speed is
The horizontal distance
Generally the the time taken is mathematically represented
=>
=>
Generally from kinematic equation we have that
Here u is the initial velocity of nut in the vertical and the value is 0 m/s
=>
