Answer:

A_{1} = 0.2 m^{2}

Explanation:

The pressure on the pistons is given as;

Pressure = \frac{Force}{Area}

So that,

Pressure on the small piston = \frac{F_{1} }{A_{1} } and Pressure on the large piston = \frac{F_{2} }{A_{2} }

Thus,

\frac{F_{1} }{A_{1} } = \frac{F_{2} }{A_{2} }

Given that: F_{1} = 100 N, F_{2} = 2000 N, A_{2} = 4 m^{2}.

\frac{100}{A_{1} } = \frac{2000}{4}

A_{1} = \frac{100*4}{2000}

    = \frac{400}{2000}

    = 0.2

A_{1} = 0.2 m^{2}

The area of the small piston is 0.2 m^{2}.

A toy car is given an initial velocity of 5.0 m/s and experiences a constant acceleration of 2.0 m/s656-03-02-00-00_files/i02900
Whitepunk [10]
It would be 17 m/s

If we use

V2 = V1 + a*t
Sub in 5 for v1
2m/s*2 for a
And
6 for t
That should give you the answer.

Normal atmospheric pressure is 1.013 105 Pa. The approach of a storm causes the height of a mercury barometer to drop by 27.1 mm
Burka [1]

Answer:

The atmospheric pressure is 0.97622\times10^{5}\ Pa.

Explanation:

Given that,

Atmospheric pressure P_{atm}= 1.013\times10^{5}\ Pa    

drop height h'= 27.1 mm

Density of mercury \rho= 13.59 g/cm^3

We need to calculate the height

Using formula of pressure

p = \rho g h

Put the value into the formula

1.013\times10^{5}=13.59\times10^{3}\times9.8\times h

h =\dfrac{1.013\times10^{5}}{13.59\times10^{3}\times9.8}

h=0.76\ m

We need to calculate the new height

h''=h - h'

h''=0.76-27.1\times10^{-3}

h''=0.76-0.027

h''=0.733\ m

We need to calculate the atmospheric pressure

Using formula of atmospheric pressure

P=\rho g h

Put the value into the formula

P= 13.59\times10^{3}\times9.8\times0.733

P=0.97622\times10^{5}\ Pa

Hence, The atmospheric pressure is 0.97622\times10^{5}\ Pa.
