The speed of the large fish after eating the small fish is 4.76 m/s.
We can apply the law of momentum conservation to calculate the speed of the large fish.
Let the velocity of the large fish after eating small fish is v.
According to law of momentum conservation
m1u1+m2u2=(m1+m2)v
here, m1 is the mass of the large fish, u1 is the initial speed of larger fish, ml is the mass of the small fish, u2 is the initial speed of small fish
10*5+0.5*0=(10+0.5)v
v=4.76 m/s
The paper clip did because it is a conductor. A pencil is made with wood and that is an insulator.
Answer:
<h2> 145km</h2>
Explanation:
The displacement is a vector quantity, it tells how far away from a point a distance or a destination is
given that the distance covered are
50. km, 30. km, and 65 km
the displacement is expressed as
= 50+30+65
=145km
We actually performed straight addition because in all the movement the antarctic explorers did not record any deviation from the initial direction, hence they maintained a linear movement from the beginning to the end
Answer:
Moon appears lit on the right half of the Moon during the First Quarter. The Moon appears lit on the left side during the Third Quarter because the Moon is on the other side of Earth. Again, if you think of the baseball analogy, and you’re standing at home plate, the first base or First Quarter is on your right side.

Answer:
Zero
Explanation:
Impulse is defined as the change in momentum.
Impulse is also defined as the product of force and the time duration of application of the force.
In the given problem, since there is no motion in the vertical direction, therefore the velocity of the box along the vertical direction is zero. So, momentum of the box along the vertical is also zero.
Hence the change is momentum is also zero along vertical direction.
Thus the impulse delivered by the box is zero.
