Answer:
<em>Fission</em> means breaking.
The process of combining two small nuclei is called <em>fusion</em>.
Explanation:
The process of breaking a heavy nuclei to form two or more lighter nuclei is called <em>Fission</em>.
The heavy nuclei ,like Uranium, are bombarded with slow moving electrons, which are known as thermal electrons. On bombarding, the nuclei disintegrates to form two or more smaller nuclei releasing a huge amount of energy in the process. Fusion is a exothermic process.
The process of fusion is used in nuclear reactors.
Example:
The process of combining two lighter nuclei to form a heavier nuclues is called Fusion.
Energy is released or absorbed during the process.
Fusion takes place in the sun.
Hi there!
We can use the following equation to derive acceleration:
vf = vi + at, where:
vi = 0 m/s (starts from rest)
a = acceleration
time = time (sec)
Rewrite:
vf = at
Solve for acceleration:
vf/t = a
30/6 = 5 m/s²
Answer:
<em>time = 6.9 s</em>
<em></em>
Explanation:
velocity of the plane v = 22.7 m/s
acceleration of the train a = -3.3 m/s^2
it finally comes to res, final velocity u = 0 m/s
time t = ?
using the equation
v = u + at
substituting, we have
0 = 22.7 + (-3.3)t
0 = 22.7 - 3.3t
3.3t = 22.7
t = 22.7/3.3 = <em>6.9 s</em>
