As the cloud shrank, its gravitational potential energy was converted to kinetic energy and then into thermal energy.
The time for the javelin in the air will be 3.977 second
<h3>What is the period?</h3>
The value of time needed to complete the upward and the downward motion is the total period. Its unit is the second and is denoted by t. T is the time at which the ball first hits the ground.
Given data;
Θ is the angle of throw = 43.2°
u is the thrown velocity = 28.5 m/s
t is the time for the javelin in the air
The time period is found as;
Hence the time for the javelin in the air will be 3.977 second

There are 5 atoms 1=LI 1=N 3=O
Answer:
-4.33m/s
Explanation:
Using the law of conservation of momentum
m1u1+m2u2 = (m1+m2)v
m1 and m2 are the masses
u1 and u2 are their respective velocities
v is the final velocity
From the question;
m1 = 4000kg
m2 = 6000kg
u1 = 4m/s
u2 = ?
v =-1m/s
Substitute into the formula and get u2
4000(4)+6000u2 = (4000+6000)(-1)
16000 + 6000u2 = -10000
6000u2 = -10000-16000
6000u2 = -26000
6u2 = -26
u2 = -26/6
u2 = -13/3
u2 = -4.33m/s
Hence the velocity of the truck is -4.33m/s
Total absorption of the light takes place in every image. There is no light left to proceed to our eyes, and that's why we can't see any of the images.
The absorption is so complete in each and every case, we can't even see enough to know how MANY images there are.
