Work = force x distance. So the answer would be 200x50=10000 joules
The particles released during alpha decay are called alpha particles. Alpha particles have greater mass and charge than other emitted particles.
- Radioactive emissions are the transfer of energy through the flow of particles or waves in a medium
- There are 3 types of radioactive emissions which are alpha, beta and gamma
- In alpha radiation, the nucleus emits an alpha particle which is equivalent to a helium nucleus
- In beta radiation, an electron is emitted to convert a neutron to a proton
- In gamma radiation, the nucleus just loses energy
Since alpha particles have more mass and charge, they are more ionising and lose more energy at a faster rate and can be blocked easily.

a) 10 m/s
b) 25 m
Explanation:
a)
The body is moving with a constant acceleration, therefore we can solve the problem by using the following suvat equation:
where
u is the initial velocity
v is the final velocity
a is the acceleration
t is the time
For the body in this problem:
u = 0 (the body starts from rest)
is the acceleration
t = 5 s is the time
So, the final velocity is
b)
In this second part, we want to calculate the distance travelled by the body.
We can do it by using another suvat equation:
where
u is the initial velocity
v is the final velocity
a is the acceleration
s is the distance travelled
Here we have
u = 0 (the body starts from rest)
is the acceleration
v = 10 m/s is the final velocity
Solving for s,
Answer:
Explanation:
<u>Instant Velocity and Acceleration
</u>
Give the position of an object as a function of time y(x), the instant velocity can be obtained by
Where y'(x) is the first derivative of y respect to time x. The instant acceleration is given by
We are given the function for y
Note we have changed the last term to be quadratic, so the question has more sense.
The velocity is
And the acceleration is
