1) 4°C : It has the highest density as shown on the graph.

2) Water expands when it freezes, making it less dense than just water.

3) The ice would sink to the bottom, then the rest of the water would freeze as well, the entire lake/river/whatever will freeze eliminating the organisms that live there.

Peak wavelength of light coming from a star with a temp of 4300k

PSYCHO15rus [73]

from Wein's law

$\frac{k}{ \lambda_{max} } = T \\ \lambda_{max} = \frac{k}{T} \\ \lambda_{max} = \frac{3.898 \times {10}^{ - 3} }{4300} \\ = 9.065 \times {10}^{ - 7}$

What is the strength of the electric field 3.0 cm from a small glass bead that has been charged to + 8.0 nc ?

Debora [2.8K]

Thinking the small glass bead as a single point charge, the electric field generated by it is given by
$E(r) = k_e \frac{Q}{r^2}$
where
$k_e = 8.99 \cdot 10^9 N m^2 C^{-2}$ is the Coulomb's constant
$Q=8.0 nC=8.0 \cdot 10^{-9} C$ is the charge of the bead
$r=3.0 cm=0.03 m$ is the distance at which we calculate the field.

Using these data, we find:
$E=(8.99 \cdot 10^9 N m^2 C^{-2} ) \frac{(8.0 \cdot 10^{-9} C}{0.03 m)^2}=8.0 \cdot 10^4 N/C$
