Answer:
Momentum is conserved.
All of the others are not conserved because of heat loss caused by deformation, etc.
Answer: wavelength will increase
Explanation:
Velocity is directly proportional to wavelength,as the velocity is increased, wavelength is also increased
-- The boiling points of the first group are all at temperatures
that are way lower than a comfortable room.
. . . . . Nitrogen . . . -320° F
. . . . . Helium . . . . -452° F
. . . . . Neon . . . . . -411° F
The freezing points of the second group are all at temperatures
that are way higher than a comfortable room.
. . . . . Lithium. . . . . . 357° F
. . . . . Sodium . . . . . 208° F
. . . . . Potassium . . . 146 °F
Answer:
Option B
10.36 m/s
Explanation:
Using the first given equation, then velocity=distance/time
Since distance is provided as 200 m and time, t is 19.3 seconds then substituting these figures yields
v=200/19.3=10.3626943
Rounding off to 2 decimal places, then
v=10.36 m/s
Answer:
0.00354 (N)
Explanation:
Convert to metric system:


Formula for gravitational force:

where s is the distance between 2 bodies masses m and M
Substitute the number to the formula above and since the 2 forces are acting in opposite direction, the total net gravitational force on the mass of origin be:
