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:
= -8πx
Explanation:
If you need calculate
You can use the Ampere's Law
= μ
Where : Current passing through the window
μ : Free space’s magnetic permeability
μ = 4πx
Then
= (3-5)4πx
= -8πx
In my opinion i think it is water
There are many types of structural elements. It was seen in an earlier lecture that the support condition has a significant influence on the behavior of the specific element. It is advantagous to identify certain types of structural elements which have distinct characteristics. If an element has pins or hinge supports at both ends and carries no load in-between, it is called a two-force member.
