The car's velocity at time <em>t</em> is given by

It comes to a stop when <em>v</em> = 0, which happens when

or after about 13.9 s.
In this time, the car travels a distance <em>x</em> given by

or about 192 m.
In one complete revolution, each tire covers a distance equal to its circumference,

or about 2.14 m.
This means each tire will complete approximately 192/2.14 ≈ 90 revolutions.
Yes. Newton's laws do not apply at the subatomic level. There you are entering the weird world of Quantum Theory. Go read about the '2 holes experiment'. It will blow your mind.
Answer: a graduated cylinder and balance
A rock has an irregular shape. so, it would be difficult to measure using a meter stick. most convenient method to find the volume would be using a graduated cylinder. we can take a fixed volume of water in the cylinder. then drop rock into it. note the new raised volume. Subtract the initial volume from final to find the volume of rock.
Using balance, mass of the rock can be measured.
we can calculate the density using the following formula:

Therefore, we need only two tools, a graduated cylinder and a balance to measure mass, volume and density of a rock.
Answer:
The answer will be 936 N.
Explanation:
Given that
m = 80 kg
Acceleration of the elevator , a= 1.7 m/s² ( upward)
The gravity force on the mass = m g
The reading on the scale = F N
Now by applying the Newton's second law
F - m g = ma
F= m g + m a
F= m ( g +a )
F= 80 ( 10 + 1.7 ) N ( take g= 10 m/s²)
F=80 x 11.7 N
F= 936 N
Therefore the reading on the scale will be 936 N.
The answer will be 936 N.
We can't tell what RATING is printed on the package of bulbs, but right now, the bulb is dissipating IxE= 30 watts of heat and light.
