Answer:
+12 m/s
Explanation:
The velocity of an object moving of accelerated motion is given by:
where
v0 is the initial velocity of the object
a is the acceleration
t is the time
In this problem, the rocket starts from rest, so 
. The acceleration is 
, so the velocity after 
will be
Answer:
=−2.451 330 152 1*10^27J
Explanation:
The electric potential=the Voltage * Charge:
E = VQ
V = 1.53x10^8 V (positive, because the cloud has a higher potential)
Q = -1.60217657 x10^19 C (the charge of an electron)
E = (1.53x10^8 V )* (-1.60217657 x10^19 C)
E=−2.451 330 152 1*10^27J
The negative sign indicates that the potential energy is decreased by the movement of the electron.
The object's velocity is decreasing.
Explanation:
From graph is the attached image, we can clearly point that the velocity of this motion is decreasing with time.
Velocity is a vector quantity.
- The y-axis represent displacement.
- The x-axis depicts time
- Using the graph, we know that the slope of the line on the graph gives us the velocity as it denotes the change of displacement with time.
- When we find the slope, it will give us a negative value which shows that the body is slowing down and not increasing speed.

Answer:
Explanation:
The half life is the time taken for half of a radioactive substance to disintegrate.
The shorter the half life, the larger the decay constant and the faster the decay process.
For a very large half life, it would take a very long time for the radioactive nuclide to decay to half.
With each half life reached, a new set of daughter cell is formed. Atoms that have short half life would decay rapidly. Every radionuclide has its own characteristic half-life.
If the number of half-lives increases, then the number of radioactive atoms decreases, because approximately half of the atoms' nuclei decay with each half-life. With this observation, we can hypothesise and conduct experiment to support the assertion that as the number of half-lives increases then the number of radioactive atoms decreases.
