The major functions of the bones are body support, facilitation of movement, protection of internal organs, storage of minerals and fat, and hematopoiesis.
The net force required to accelerate a car is 6000 N.
Force is defined as the product of the mass and acceleration of the body. Force is used to changing the velocity that is to accelerate an object or a body of a particular mass. The unit of Force is Newton or kg m/s^2.
The formula used to calculate the net force is :
F = ma
where, F = Force
m = mass = 2000 kg
a = acceleration = 3.00 m/s^2
∴ F = 2000*3
F = 6000 N
Thus, to accelerate the car at 3.00 m/s^2 of mass 2000 kg net force required is 6000 N.

The correct answer would be compound
Answer:
far from the speaker the intensity drops to 85 dB.
Explanation:
In the equation for the Decibel scale

The ratio of the intensities can be written as


And since

and
,

meaning

Putting this into equation (1), we get:

Now, if the intensity is 100 dB when the distance is 5 meters, we have:


by taking both sides to the exponent:


Now equation (2) becomes

when the intensity level is 85 dB we have


take both sides to exponents and we get:




Thus,
far from the speaker the intensity drops to 85 dB.
