Answer:
you would expect a change in the graph
Explanation:
All you need to do is count the number of Oxygen the Products:
In 6H2O, you have 6 oxygen, and in 6CO2, you have 6 Dioxygen so 12 Oxygen. So a total of 12 + 6 = 18 atoms of Oxygen, or 9 atoms of dioxygen.
So the coefficient that should be placed in front of O2 to balance the reaction is 9:
C6H12 + 9O2 ---> 6H2O + 6CO2

Answer:
1 m/s^2
Explanation:
The formula for accleration is a=Δv/Δt
where, Δv = final velocity - initial velocity = 4 - 0 = 4
initial velocity = 0 since the car starts form rest and final velovity is 4 as the car goes from rest till 4 m/s
Δt = 4 since the car takes 4 seconds to reach a velocity of 4m/s
Hence, a = 4 m/s / 4 s = 1 m/s^2
Answer:
<h2>2000 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 1000 × 2
We have the final answer as
<h3>2000 N</h3>
Hope this helps you
<span>The friction force ( µ . N ) must be enough to counter the gravity force ( m . g )
The Normal force from the rotating wall is the centripetal force = mv^2 / r
so with the lowest coefficient of friction ( 0.4 )
0.4 . v^2 / 2.5 = g
v^2 = 2.5 . 9.8 / 0.4
v = 7.83 m/s
T = 5Ď€ / 7.83 = 2.007 s
f = 0.5 Hz = 30 rpm</span>
