First, we define an equilibrium as a state of balance. A static equilibrium is when there are no forces acting on a system, or more technically, when the vector sum of the forces is zero. A dynamic equilibrium is when there are continuous forces that are balanced, and the system resists outside change.

A reaction at dynamic equilibrium<span> can be reversible, whereas a reaction at </span>static equilibrium<span> is irreversible. A reversible reaction is a reaction that can proceed in the direction of products to reactants. ... It is at </span>static equilibrium<span> if the reaction has occurred and the forward and reaction rates are both equal to 0.

If you ride your bike at an average speed of 2 km/h and need to travel a total distance of 20 km, how long will it take you to r
love history [14]

Answer:

Time taken to reach your destination will be 10hours

Explanation:

Recall the formula for Speed;

speed=Total distance/Total time taken

Speed=2km/h

Total distance=20km

Time taken=x

let x be the unknown time taken

Input each values into the formula;

2=20/x

Making x subject of the equation

x=20/2

x=10

Total time taken =10hours.

A boy whirls a ball on a string in a horizontal circle of radius 0.65 m. If the ball is traveling at 9 m/s, what is the centripe
djverab [1.8K]

Answer:

ac = 124.6 m/s²

Explanation:

When an object executes a uniform circular motion, acceleration is produced in it due to a change in its direction during the motion. This acceleration is called the centripetal acceleration. The formula used to find this acceleration is given as follows:

a_{c} = \frac{v^{2}}{r}\\

where,

ac = centripetal acceleration = ?

v = speed = 9 m/s

r = radius = 0.65 m

Therefore,

a_{c} = \frac{(9\ m/s)^{2}}{0.65\ m}\\

<u>ac = 124.6 m/s²</u>
