The principle of a lever is when two equal forces act in opposite directions and ultimately come to a state of equilibrium if distanced properly
i hope that helps?^
Answer:
4cm
Explanation:
Magnification of the virtual image
= image distance / object distance
Given
Image distance = 60.0cm
Object distance = 15.0cm
Therefore,
Magnification = 60.0/15.0
= 4 cm
<h2>Answer</h2>
1m/s
<h2>Explanation</h2>
Given that:
<em>Mass of first blob = 2kg = m1</em>
<em>Velocity of blob = 4m/s = v1</em>
<em>Mass of second blob = 6kg = m2</em>
<em>Velocity of blob = 0m/s = v2</em>
<em />
To find:
<em>Final velocity = Vf</em>
<em />
<em>This question is of inelastic collision which is any collision between objects in which some energy is lost.</em>
<em />
<h3>Formula to be use:</h3><h2>(m1*v1) + (m2*V2) = Vf(m1 + m2)</h2>
(2*4) + (6*0) = Vf(2+6)
8 + 0 = Vf(8)
8 = Vf(8)
Vf = 1 m/s
So the speed of two blobs immediately after colliding = 1 m/s
Answer:
2 in front of water and 1 in front of oxygen
Explanation:
If the strength of a magnetic field at B is three units the strength of the magnetic field at A, means that point B has three times more turns as compared to point A.
<h3>How strength of the magnetic field should be increased?</h3>
We can increase the strength of the magnetic field by increasing the number of turns which increases the strength of the current flow.
So we can conclude that point B has three times more turns as compared to point A.
