Answer:

Kepler's third law

Explanation:

As per Kepler's third law all planets revolve around the Sun in such a way that their square of time period of revolution around the Sun is proportional to the cube of the mean radius.

It is given as

$T^2 = cR^3$

here

c = proportionality constant

R = mean radius

T = time period around the sun

So here all celestial body and all planets revolve as per the Kepler's third law which is also known as law of harmonies

Blood takes about 1.65 s to pass through a 2.00 mm long capillary. If the diameter of the capillary is 5.00 μm and the pressure

Murrr4er [49]

Answer:

Viscosity of blood will be $918.54\times 10^{-6}Pa-sec$

Explanation:

We have given time to pass the capillary = 1.65 sec

Length of capillary L = 2 mm = 0.002 m

Pressure drop $\Delta P=2.85kPa=2.85\times 10^3Pa$

Diameter $d=5\mu m=5\times 10^{-6}m$

So radius $r=\frac{5\times 10^{-6}}{2}=2.5\times 10^{-6}m$

Velocity will be $v=\frac{L}{t}=\frac{0.002}{1.65}=1.212\times 10^{-3}m/sec$

We know that viscosity is given by $\eta =\frac{r^2\Delta P}{8Lv}=\frac{(2.5\times 10^{-6})^2\times 2.85\times 10^3}{8\times 0.002\times 1.212\times 10^{-3}}=918.54\times 10^{-6}Pa-sec$

Viscosity of blood will be $918.54\times 10^{-6}Pa-sec$

What tools/information do you think meteorologists need to predict the weather?

Over [174]

Answer:

Meteorologists use a variety of tools to help them gather information about weather and climate. Some more familiar ones are thermometers which measure air temperature, anemometers which gauge wind speeds, and barometers which provide information on air pressure.

Which statement accurately describes the relationship between force and momentum?

Ymorist [56]

Answer:

Force, on the other hand, is the push or pull that is applied to an object to CHANGE its momentum. Newton's second law of motion defines force as the product of mass times ACCELERATION (vs. velocity). you can connect the two concepts with the following relationship: force = mass x (velocity / time) = (mass x velocity) / time = momentum / time
