FIrst, just write down what we know :)

1. 1 mile = 1.6klm
2. There are 3600 seconds in an hr (<em>60s x 60mins = 3600</em>).

Now to get to <em>meters per second</em> (m/s) we need to first work out <em>meters per </em><em>hr</em> (simply convert miles to klm and then multiply by 1000)<em>.</em>

60 x 1.6 = 96 klm/hr x 1000 = 96,000 meters/hr

Now we know this, we can simply divide the meters per hr by <em>how many seconds there are in 1hr</em> to get meters per second:

96000 / 3600 = 26.67m/s

. If measurements of a gas are 75L and 300 kilopascals and then the gas is measured a second time and found to be 50L, describe
julia-pushkina [17]
By Boyle's law:

P₁V₁ = P₂V₂

300*75 = P<span>₂*50

</span>P<span>₂*50= 300*75
</span>
P<span>₂ = 300*75/50 = 450
</span>
P<span>₂ = 450 kiloPascals.

The pressure has increased as a result of compression of gas.

Boyle's Law supports this observation.</span>

A thin stream of water flows smoothly from a faucet and falls straight down. at one point the water is flowing at a speed of v1
kati45 [8]
<span>The formulas are, v1d1² = v2d2² ........ (1) h = (v2²-v1²)/2g ...... (2) Given that, v1 = 1.71 m/s we assume that the stream has decreased by a factor d2 =0.805d1 then, v1d1² = v2 (0.805d1)² cancelled both side d1² then we get, v1 = v2 (0.805)² v1 = v2 (0.648025) Sub v1 = 1.71, 1.71 = v2 (0.648025) v2 = 1.71/0.648025 v2 = 2.638787083831642 v2 = 2.64 m/s The vertical distance formula, h = (v2²-v1²)/2g We know that value of gravity constant is 9.8 m/s² h = {(2.64)² - (1.71)²)/2(9.8) h = {(6.9696) - (2.9241)}/19.6 h = (4.0455)/19.6 h = 0.2064030612244898 h = 0.21 cm Therefore, the vertical distance h = 0.21 cm.</span>

A car accelerates along a straight road from rest to 90 km/h in 5.0 s. A) Find the magnitude of its average acceleration. B) Fin
egoroff_w [7]

Answer:

a)   A=5m/s^2

b)   V=25m/s

Explanation:

From the question we are told that:

Velocity v=90km/h=25m/s

Time t=5.0s

a)

Generally From Newton's motion equation for Average acceleration is   mathematically given by

  A=\frac{V-U}{t}

Since its from Rest Therefore

  U=0

 A=\frac{25m/s-0}{5s}

 A=5m/s^2

b)

Generally the equation for Average Velocity is mathematically given by

  V=u+at

 AT t=1.0s\\\\V=0+5(1)

 V=5m/s

 AT t=2.0s\\\\V=0+5(2)

 V=10m/s

 AT t=5.0s\\\\V=0+5(5)

 V=25m/s

Describe motion of the sun
Olenka [21]

Answer:

The apparent motion of the sun, caused by the rotation of the Earth about its axis, changes the angle at which the direct component of light will strike the Earth. From a fixed location on Earth, the sun appears to move throughout the sky.
