A decomposition reaction is a reaction in which a single reactant is broken down into 2 or more products.
Answer:
y = 77.74 10⁻⁵ m
Explanation:
For this exercise we can use Newton's second law
F = m a
a = F / m
a = 4.9 10⁻¹⁶ / 9.1 10⁻³¹
a = 0.538 10¹⁵ m / s
This is the vertical acceleration of the electron.
Now let's use kinematics to find the time it takes to move the
x= 29 mm = 29 10⁻³ m
On the x axis
v = x / t
t = x / v
t = 29 10⁻³ / 1.7 10⁷
t = 17 10⁻¹⁰ s
Now we can look for vertical distance at this time.
y = t + ½ a t²
y = 0 + ½ 0.538 10¹⁵ (17 10⁻¹⁰)²
y = 77.74 10⁻⁵ m
Answer:
7.5 meters per second
Explanation:
30 / 4 = 7.5
7.5 * 1 = 7.5
7.5 * 2 = 15
7.5 * 3 = 22.5
7.5 * 4 = 30
Part a)
At t = 0 the position of the object is given as
At t = 2
so displacement of the object is given as
so average speed is given as
Part b)
instantaneous speed is given by
now at t= 0
at t = 1
at t = 2
Part c)
Average acceleration is given as
Part d)
Now for instantaneous acceleration
As we know that
at t = 0
at t = 1
now we have
At t = 2 we have
<em>so above is the instantaneous accelerations</em>
