Answer:
13.3 m/s
Explanation:
The motion is a projectile motion. The horizontal distance travelled, called the range, is given by

u is the initial speed,
is the angle with the horizontal and g is acceleration of gravity.

Answer: 1) Cold water is more dense and will sink in room temperature water.
2) Cold salty water is denser than warm freshwater.
3) Temperature is the measure of heat. Density is the measure of how closely any given entity is packed or it is the ratio of the mass of the entity to its volume.
4) Salinity and density share a positive relationship. As density increases, the amount of salt in water-also known as salinity- increases.
To solve this problem, apply the concepts given from Ohm's Law. From there we will obtain the derivative of the function with respect to time and with the previously given values we will proceed to find the change in current as a function of the derivative

Here
I = Current
V = Voltage
R = Resistance
Taking the derivative we will have,

Our values are given as,




Replacing we will have that


Rearranging to find the current through the time,


Therefore the change of the current is -0.000026A per second
