Given that,
Mass of the object, m = 1 kg
It moves in a circle of radius 0.5 m with a speed of 5 m/s
To find,
The direction of the acceleration.
Solution,
Whenever an object moves in a circular path, the only force that acts on its is centripetal force which is given by the formula as follows :
The centripetal acceleration acts in the direction of force. It acts along the radius of the circular path. In this figure, the direction of the acceleration is shown at point d.
The question just basically explained what happens
The temperature of the rocks is just equal to the temperature of the glass, water and plastic plants for they are in thermal equilibrium.
Answer:
The distance is 
Explanation:
From the question we are told that
The time interval between the sounds is k
= 0.50 s
The speed of sound in air is 
The speed of sound in the concrete is 
Generally the distance where the collision occurred is mathematically represented as
Now from the question we see that d is the same for both sound waves
So
Now
So 
=> 
=>
=> 
So
