Answer:

Explanation:

kinetic energy will be converted to work of friction

½mv² = Fd

d = mv²/2F = 1000(35²) / (2(8000)) = 76.5625 ≈ 77 m

will be the minimum stopping distance d

How can you drop two eggs the fewest amount of times, without them breaking?
MrMuchimi

Answer:

Both eggs are identical. The aim is to find out the highest floor from which an egg will not break when dropped out of a window from that floor. If an egg is dropped and does not break, it is undamaged and can be dropped again. However, once an egg is broken, that's it for that egg.

Why is an object's density expressed as a combination of two units
miss Akunina [59]
Well, first of all, EVERY physical quantity is measured in a combination
of 2 or more units, except for mass, length, time, and electric charge. 
ALL other units are made out of these.  So it should not surprise you.

[  Example:  Speed  =  (length) / (time)  ]

Density is not the mass of a substance.  It's the mass of a substance in
a standard volume of it.  So the density is made of the mass in any lump
and the volume of that lump.  That way, no matter how much of a substance
you have, you can always compare the lump you have to all other substances.

While spending the weekend in your cabin, you burn wood in your pot-bellied stove to heat a kettle of water for tea.
Olegator [25]

Answer: 1 = Heat

2=gas

3=it gets hot enough to boil because the metal conducts the heat into the water to heat it up and eventually boil.

The mass of a star is 1.61·1031 kg and its angular velocity is 1.60E-7 rad/s. Find its new angular velocity if the diameter sudd
Tcecarenko [31]

Answer:

ω₂ = 1.9025 x 10⁻⁶ rad/s

Explanation:

given,

mass of star = 1.61 x 10³¹ kg

angular velocity = 1.60 x 10⁻⁷ rad/s

diameter suddenly shrinks = 0.29 x present size

      r₂  = 0.29 r₁

using conservation of angular momentum

I₁ ω₁ = I₂ ω₂

(\dfrac{2}{5}mr_1^2)\omega_1=(\dfrac{2}{5}mr2^2)\omega_2

r_1^2\times \omega_1=r_2^2\times \omega_2

r_1^2\times 1.60\times 10^{-7}=(0.29r_1)^2\times \omega_2

1.60\times 10^{-7}=0.0841\times \omega_2

\omega_2=\dfrac{1.60\times 10^{-7}}{0.0841}

   ω₂ = 1.9025 x 10⁻⁶ rad/s
