Answer:
1.5 m/s^2
Explanation:
Force = 3000 Newtons
Mass = 2000 kilograms
Force = Mass x Acceleration
This rearranged to:
Acceleration = Force / Mass
Acceleration = 3000 / 2000 = 1.5 m/s^2
A reaction between two pure solids is very rare. For a reaction to occur, the molecules must interact with each other. Since molecules of solids are very compact, they don't have the liberty to collide with one another. However, this is made possible by hydrates of solids. An examples would be CuSO₄·5H₂O. In this case, they have a an intermediate liquid to react them together.
Answer:
0.0196 j
Explanation:
i) The formula for kinetic energy is as follows: 0.5*m*v^2
ii) Since we have all the values all that's left is to plug them into the equation
iii) First, WE MUST, Convert grams into kgs as this is the SI unit of mass so 2.45/1000
iv) All that's left now is to plug it into the equation so:
0.5* (s.45/1000)*(4^2)
v) Lastly we add the unit joules at the end as we're talking about energy
Hope this was useful! :)

Answer:
Explanation:
According to ohm's law current flowing in a conductor is directly proportional to the voltage applied across two end of conductor.
i.e. ![V\propto R](https://tex.z-dn.net/?f=V%5Cpropto%20R)
![V=R I](https://tex.z-dn.net/?f=V%3DR%20I)
where R=resistance
![R\propto L](https://tex.z-dn.net/?f=R%5Cpropto%20L)
![R\propto \frac{1}{d^2}](https://tex.z-dn.net/?f=R%5Cpropto%20%5Cfrac%7B1%7D%7Bd%5E2%7D)
whee L and d are length and Diameter
thus ![R=k \frac{L}{d^2}](https://tex.z-dn.net/?f=R%3Dk%20%5Cfrac%7BL%7D%7Bd%5E2%7D)
where k=constant of Variation
