Answer:
The net force acting on this object is 180.89 N.
Explanation:
Given that,
Mass = 3.00 kg
Coordinate of position of 
Coordinate of position of 
Time = 2.00 s
We need to calculate the acceleration

For x coordinates

On differentiate w.r.to t

On differentiate again w.r.to t

The acceleration in x axis at 2 sec

For y coordinates

On differentiate w.r.to t

On differentiate again w.r.to t

The acceleration in y axis at 2 sec

The acceleration is

We need to calculate the net force



The magnitude of the force


Hence, The net force acting on this object is 180.89 N.
D= M÷V is the equation you're looking for. It means Density = Mass ÷ Volume
Answer:
4
Explanation:
= Threshold intensity for woman
I = Intensity of sound for man
= Intensity level of sound = 6 dB
Intensity level of sound is given by

The ratio is 4
Physics can be used in a variety of ways, a specific example would be rollercoaster. Physics can be used to determine the speed at which a rollercoaster can travel without going off the rails or when it needs to begin to slow down to make a sharp turn.
Answer:
frequency
Explanation:
speed of light = <u>constan</u>t = wavelength * frequency
changing WL or F will change the other
