A rock weighing 8654 N rock with a volume of 36 L is completely submerged in mercury. The density of mercury is 13.6 kg/L.
How do I calculate the buoyant force of a rock if the density is 24.529 kg/L
(question continued) vertical plane. If a constant angular speed of 8.00 rad/s is maintained, what is the tension in the string when the object is at the top of the circular path?
a) 18.88 N
b) 10.5
between temperature extremes of -20°C and 35°C?-The equation for linear expansion (e) is ..
e =Lo.α.∆θ .. (in m)
α = coef.of linear expansion
Lo = original length in m
∆θ = temperature change in ºC
I learnt that when there are effects, a force is acting on a particular object. But when one pushes against a pillar, one is acting a push force on the pillar. But yet I cant see any effect. So, is my
(Question continued) horizontal. The magnitude of the horizontal component of the balls initial velocity is which of the following?
a) 5 m/s
b) 8.7 m/s
c) 10 m/s
d) 9.8 m/s-V_h = v * cos(30)
v_h = 10
If a positive test charge is halfway in between 2 oppositely charged point charges
then the electric potential is zero.
Then why if you release that charge does it accelerate toward the negative char
Fahrenheit scales.-F = 1.8*C + 32
Let C = -40
F = 1.8*(-40) + 32
F = -72 + 30
F = -40
It is unique because the relationship is linear in one variable. There can be, at most, one solution-Let the te
I know a strong force holds protons & neutrons together in an atoms nucleus.
But are nuclear fusion & nuclear fission types of strong forces or are they just simply nuclear reactions all their own?
A hammer mass 30 kg, was tied to a 5.0m long rope. It swings from rest at position X and falls to position Y...
at the center was the other end of the rope, and to the right is the end tied to the ham
If potential difference in induced electric field due to changing magnetic field has no meaning then what does induced EMF mean?-An electric field does have a meaning.At any point in space there is an
I know the entropy equation is change in thermal energy divided by the temperature equals change in entropy.
But what is temperature?Is it just a measure of its temperature on a thermometer?
In anot
T= 1/16Pi^2 X c^3h/GMk
And why speed of light cubed?-http://en.wikipedia.org/wiki/Planck_temp…
It does not quite match your equation, but I think that is what you are looking at.
I have a few problems that Im stuck on... If you can help with any/all of the it would be amazing!Here they are:
