The four tires of an automobile are inflated to a gauge pressure of 2.2 105 Pa. Each tire has an area of 0.023 m2 in contact wit
Stels [109]

Answer:

Force, F = 20240 N

Explanation:

It is given that,

Pressure exerted by the four tires of an automobile, P=2.2\times 10^5\ Pa

Area of each tire, A=0.023\ m^2

Area of 4 tires,  A=0.092\ m^2

We know that the pressure exerted by an object is equal to the force per unit area. Its formula is given by :

P=\dfrac{F}{A}

F=P\times A

F=2.2\times 10^5\times 0.092

F = 20240 N

So, the weight of the automobile is 20240 N. Hence, this is the required solution.

What is a conversion factor?
rosijanka [135]

Answer:

A ratio of equivalent units

Explanation:

A conversion factor is a ratio of equivalent units and depends on which units are to be converted.

For example we want to convert 275 [mm] to inches, so we have to find the right conversion factor to allow us to work that conversion.

275 [mm] = inches = ?

275 [mm] * \frac{1in}{25.4mm} = 10.82 [in]

In this case the ratio is 1/25.4 = 0.039 [in/mm]

A driver traveling at 30.0 m/s presses the brakes decelerates at -8.80 m/s^2. How much time, in second, does it take her to come
Kruka [31]

Answer:

It takes her 3.409 seconds to make a full stop.

Explanation:

The time it takes to make a full stop can be determined by the equation of velocity for a Uniformly Accelerated Rectilinear Motion:

v_{f} = v_{i} + at  (1)

Where v_{f} is the final velocity, v_{i} is the initial velocity, a is the acceleration and t is the time.

Equation (1) can be rewritten in terms of t:

v_{f} - v_{i} = at    

t = \frac{v_{f} - v_{i}}{a}  (2)  

For this particular case the final velocity will be equal to zero (v_{f} = 0):

t = \frac{0 m/s - 30.0 m/s}{-8.80 m/s^{2}}

t = 3.409 s

So it takes her 3.409 seconds to make a full stop.
