A node is a point on a standing wave that has no displacement from the rest position. at the nodes, _____.

nikdorinn [45]

Nodes are points along the medium that appear to be standing still. They are points on a standing wave that has no displacement from the rest position.
Antinodes are the opposite of nodes. Those are points that undergo the maximum displacement.
At the nodes the destructive interference occurs . For example a crest of one wave meets a trough of a second wave , or a half-crest of one wave meets a half-trough of a second wave...

Gravity causes objects to be attracted to one another. This attraction keeps our feet firmly planted on the ground and causes th

aev [14]

Answer:

A) G = m³/kg.s²

B) E = kg.m²/s²

Explanation:

The given relation is:

F = Gm₁m₂/r²

where, the units of all variables are:

F = Force = kg.m/s²

m₁ = m₂ = mass = kg

r = distance = m

G = Gravitational Constant = ?

Therefore,

kg.m/s² = G(kg)(kg)/m²

(kg.m/s²)(m²/kg²) = G

G = m³/kg.s²

The given equation is:

E = mc²

where, the units of all variables are:

m = mass = kg

c = speed = m/s

E = Energy = ?

Therefore,

E = (kg)(m/s)²

E = kg.m²/s²

This is the correct answer, which is not present in any option.

At what pressure will the mean free path in room-temperature (20?c) nitrogen be 1.5 m ?

kondaur [170]

In physical chemistry, the mean free path is the average distance between the atoms during collision. Its formula is

$Mean \ free \ path \ = \frac{RT}{ \sqrt{2} \pi d^{2} N_{A}P }$

where d is the diameter of the Nitrogen atom (d = 310 x 10^-7 m), Na is Avogadro's number (Na=6.022 x 10^23), R is the gas constant (8.314 J/mol-K), T is the absolute temperature (T= 20 + 273 = 293 K). Substituting the values,

$1.5 = \frac{(8.314)(293)}{ \sqrt{2} \pi (310 \ x\ 10^{-7} )^{2} (6.022 \ x\ 10^{23} )P }$
P = 6.32 x 10^-13 Pascals
