It is the same, there is no difference.
In fact, the force of gravity on an object is equal to the weight of the object, defined as
where m is the mass of the object and g=9.81 m/s^2 is the acceleration of gravity, As we can see, the magnitude of this force depends only on the mass of the object: in this problem, both the objects (the piece of iron and the piece of glass) have same mass (1 kg), therefore they have same weight, and same force of gravity.
Answer: 12.0 m/s^2
Explanation:
Let be the angular acceleration of the end of the rod
Taking torque about the link, we have:
Torque is also given in terms of moment of inertia of the rod and its angular acceleration i.e.
From equations (i) and (ii) we have:
The acceleration of the end of the rod farthest from the link is given by:
It is possible. If you trap it in a certain space, it will be possible.
The important point here is that volumetric flow rate in the pump and the pipe is the same.
Q = AV, where Q = Volumetric flow rate, A = Cross sectional area, V = velocity
Q (pump) = (π*15^2)/4*2 = 353.43 cm^3/s
Q (pipe) = (π*(3/10)^2)/4*V = 0.071V
Q (pump) = Q (pipe)
0.071V = 353.43 => V = 5000 cm/s
Therefore, the flow of water in the pipe is 5000 cm/s.
Answer:
4 seconds
Explanation:
Given:
v₀ = 12 m/s
v = 32 m/s
a = 5 m/s²
Find: t
v = at + v₀
32 m/s = (5 m/s²) t + 12 m/s
t = 4 s
