Answer:
The change in momentum for the bug and the car will be equal, impulses will be equal in opposite directions and the bug will have a greater acceleration compared to the car, because it has a smaller mass.
Explanation:
Hope this helps..
Answer:
Explanation:
The magnetic moment of the coil M = current x area of loop
= I x L x L
M = L² I .
Magnetic field = B
Torque = M x B
= MB sinθ where θ is angle between M and B . Direction of M is perpendicular to face of loop
Torque = MB sin90
= MB
= L² I B .
Answer:
True
Explanation:
The reproductive success of any species is the capability to produce their offspring per breeding lifetime or event.
Most of the species have to attract their partners by their physical capability and build up so that the mother can choose her partner in order to breed the best kind of off spring.
In the context, in case of deer, the size of the their antlers as well as behavior in herding is considered as the best chances for a successful reproduction to compete among the males and find their breeding mate.
Thus the answer is TRUE.
Answer:
True
Explanation:
A convex mirror is a mirror whose outer bulging surface is the reflecting surface.
A convex mirror is used to see the distant objects and the image formed by the convex mirror is always erect and small. So, it is used as the rear view mirror.
It always forms a virtual, erect and diminished image of a real object.
It never forms a real image of a real object.
<h2>
Answer: under pressure rises above the aquifer level</h2>
Explanation:
An artesian system is one that connects with an accumulation of water (aquifer) whose surface or level is above the surface of the system or well.
In other words, the upper limit of the aquifer is higher than the opening through which the liquid flows in the artesian well. This has the advantage that the water spreads without needing to be pumped.
It should be noted that its name comes from the region of <u>Artois</u>, France, where in 1126 the oldest well in Europe was drilled with these characteristics.
Therefore:
<h2>
An artesian system is present when groundwater <u>
under pressure rises above the aquifer level.</u></h2>
