Answer:
As the trailer leaks sand at a constant rate through a hole in its bottom, its acceleration increases at a steady rate. (Option A)
Explanation:
F = ma
where;
F is the force applied on the truck
m is the mass of the truck
a is the acceleration of the truck
If the driving force on the truck remain constant, then;
m₁a₁ = m₂a₂
a₁ is the initial acceleration
a₂ is the final acceleration
m₁ is the initial mass of the truck and loaded sand,
m₂ is the final mass of the truck and loaded sand, which decreases as the sand leaks at a constant rate.
a₂ = (m₁a₁ )/(m₂)
since m₁ > m₂, a₂ > a₁
Therefore, as the trailer leaks sand at a constant rate through a hole in its bottom, its acceleration increases at a steady rate.
Answer:
the correct answer is reflection
Answer:
The nature of the wave formed is a transverse progressive wave.
Explanation:
A wave is a disturbance that travels through a material medium without permanent displacement of the particles of the medium. The two major types are: transverse and longitudinal.
A transverse wave is one in which the direction of vibration of the particles of the medium is perpendicular to the direction of propagation of the wave. Examples are: water wave, light wave etc. While a longitudinal wave is one in which the direction of vibrations of the particles of the medium is parallel with the direction of propagation of the wave, creating a region of rarefaction and compression. Examples are; sound wave, wave in a rope, wave in a slinky etc.
The cited wave formed in the given question is a transverse wave because each person stands and sits after some time to create a moving (progressive) wave without them moving from their positions.
For decrease: it’s the first and last one and for increase it’s the middle two
Im not sure if this is right if not please let me know. D and B.
