<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: passes through Earth's shadow.
Explanation:
During a total lunar eclipse, the Earth lies between the Sun and the moon. All three are aligned in one straight line.
The moon does not have its own light. It reflects the sunlight. During total lunar eclipse, the earth comes between the sun and the moon and blocks the sunlight. Thus, the moon passes through the Earth's shadow and appears dark.
Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play.A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms.
Elastic modulus only depends on the type of the material which is vary material to material based on its physical properties. elastic modulus does not depend on the length or the cross-section area of the wire or the force applied on the wire. so the lengths of wire does not decide the elastic modulus. since the two wires are made out of same metal ,hence their elastic modulus will be same.
496/1127 = 0.44 = 44%

<span>A = 23.9o. </span>
<span>Fp = 1127 sin23.9 = 457 N. = Force parallel to the ramp. </span>
<span>Fn = 1127 Cos23.9 = 1,030 N. = Force </span>
<span>perpendicular to the ramp = Normal force. </span>
<span>Eff. = Fp/Fap = 457/496 = 0.92 = 92%
