It will take 20 seconds for the car to attain a speed of 34 m/s

Explanation:

  • Acceleration of an object is given by a = velocity/time.
  • Here, acceleration of the car = 1.7 m/s² and velocity = 34 m/s. Using these, find time.
  • Time =  velocity/acceleration

                 = 34/1.7 = 20 s

So it takes 20 seconds to attain a speed of 34 m/s

Answer:

P =  \pi \sqrt{\frac{(R_1+R_2)^3}{2 \ GMS}}

Explanation:

From the attached diagram below:

AC = a (1 + e) = R₂     -------- equation (1)

CD = a ( 1 - e) = R₁     ---------   equation (2)

⇒ 1 - e = \frac{R_1}{a}

e= 1 - \frac{R_1}{a}

Replacing the value for e into equation (1)

a(1+1- \frac{R_1}{a})= R_2

= 2a - R_1 = R_2

a= \frac{R_1+R_2}{2}

From Kepler's third law;

P = 2 \pi \sqrt{\frac{a^3}{GMS}}

P = 2 \pi \sqrt{\frac{(R_1+R_2)^3}{8GMS}}

P =  \pi \sqrt{\frac{(R_1+R_2)^3}{2 \ GMS}}

Why is a compound as common as water considered a "weird" chemical substance?
vodka [1.7K]
There are many many fascinating things about water that make it different than any other chemical substance. For example, it is the only known compound whose solid state is less dense than it's liquid state. It also has hydrogen bonding which gives water many "weird" properties. Many chemistry teachers revolve their entire class around the properties of water.
