Answer:
<h2>The water will move faster</h2>
Explanation:
This happens as part of the consequences of the continuity of an incompressible fluid, of which water is an example.
so as the water emerges from the wider section the flow velocity increases and vice versa.
Hence the flow velocity in indirectly proportional to the area
The continuity equation is given below for our analysis
-------------------1
where
A1= the area of the wider section of the tank
V1= the flow velocity from the wider section
A2= the area of the hole at the bottom
V2= velocity of flow at the bottom.
Answer:
Describing a Force:
To fully describe the force acting upon an object, you must describe both its magnitude and direction. Thus, 10 Newtons of force is not a complete description of the force acting on an object. 10 Newtons, downwards is a complete description of the force acting upon an object.

Answer:
47347.1936 milligrams per centimeter
Explanation:
1 pound is equal 453592 milligrams.
one meter is 100cm
10.43*453952/100= 47347.1936milligrams per cm
Answer:
(a) Magnetic force 
(b) Acceleration 
(C) Speed will remain same
Explanation:
We have given velocity of alpha particle v = 520 m/sec
Magnetic field B = 0.034 T
Charge on alpha particle 
Mass of alpha particle 
Angle between velocity and magnetic field 43°
(a) Force acting on the particle is equal to
(B) According to newton's law
F = ma. here m is mass and a is acceleration.
So acceleration
(c) As the magnetic force is always perpendicular to velocity so speed will remain same neither decreases nor increases.
Without friction, we would not be able to stop walking since we would just keep slipping like on ice.
Without friction, objects would just slip and fall with a simple blow of air
And finally without friction we wouldn't be able to use machinery like cars and etc since they would just fly off
Hope this helps!
(tell me if im right)
