The maximum is 1800 J since energy is not created nor destroyed, it is just transformed. In this example, gravitational potential energy is transformed to kinetic energy.
Final speed after collision with the wall
before collision the speed of ball initially
time taken for the collision
now as per the formula of acceleration we know that
now plug in all values in it
so acceleration is - 5 m/s/s for above situation
Answer:
Explanation:
Every chemical reaction can be represented by simple chemical equations that shows how compounds are combining to give some products.
Such reactions are usually made up of:
Reactants on the left hand side
Products on the right hand side
Reactants → Products
In this given problem;
Reactants are : Magnesium fluoride = MgF₂
Iodine in form of Iodide = I₂
Product : Magnesium iodide = MgI₂
MgF₂ + I₂ → MgI₂ + F₂

Explanation:
From the question we are told that
The radius is R
The current is I
The distance from the center
Ampere's law is mathematically represented as
![B[2 \pi r] = \mu_o * \frac{I r^2 }{R^2 }](https://tex.z-dn.net/?f=B%5B2%20%5Cpi%20r%5D%20%20%3D%20%20%5Cmu_o%20%20%2A%20%20%5Cfrac%7BI%20r%5E2%20%20%7D%7BR%5E2%20%7D)

Answer:
To decide where the balls land, we need to determine how long the balls are in the air. Both balls will take 2 seconds to hit the ground.
Explanation:
1) Time played forward : gravity & drag forces are in opposite directions so it takes a longer time to reach the ground. 2) Time played backward : gravity & drag forces are in the same direction so it takes a shorter time to reach the ground.
