Four red flags
The load being carried poses a hazard to vehicles in the proximity of the load-carrying vehicle, and so it is mandatory by law for the vehicle to make the load more visible. At night time, the load is marked using red lights, as flags would not be visible then.
Answer:
The area of the liquid surface does not affect the pressure.
C. longest wavelength
Explanation:
Photons with the lowest energy have the longest wavelength and the shortest frequency.
The energy of photons is given as:
E = hf =
where f is the frequency of photon
h is the planck's constant
∧ is wavelength
c is the speed of light
The more the frequency, the higher the energy of the photon.
Photons with low energy have long wavelength.

Hello,
The answer is "one involves displacement other involves deformation ".
Reason:
A fault is a an extended break in a body of rock (involving displacement) and a fold is a bent or curved as a result of permanent deformation.
If you need anymore help feel free to ask me!
Hope this helps!

Answer:
h = 20 m
Explanation:
height (h) = 10 m
potential energy (PE) = 50 J
kinetic energy (KE) = 50 J
what is the maximum height reached by the ball
- At 10 meters above the ground potential energy (PE) = 50 J
mgh = 50
recall that height (h) = 10
mg (10) = 50
mg = 5 .....equation 1
- The total energy of the system at 10 meters is given as PE + KE = 100 Joules. From the conservation of energy the total energy in the system still remains the same at the maximum height, this is because energy can neither be created nor destroyed but can be transformed from one form to another.
- At the maximum height the velocity (v) of the system is 0, which means all its kinetic energy (KE) is converted to potential energy. Therefore the system consist only of potential energy.
KE + PE = 100
+ mgh = 100 J
velocity (v) = 0 at maximum height therefore
0 + mgh = 100
mgh = 100
recall that mg = 5 from equation 1, therefore
5h = 100
h = 20 m
