The answer will be C because when the biker brakes, heat will be generated because of the friction
We determine the rate of a reaction from the given rate law by substituting the given concentrations and the order of the substances. We calculate as follows:
<span>rate = k[A]^m[B]^n
</span><span>rate = (1 x 10^-2) [2]^2 [3]^1
rate = 0.12 M /s
The rate law of a reaction is an expression that is related to the reaction rate. The parameters used are the concentration or the pressure of the reactants in the reaction. An example would be:
</span><span>
A = B + C
The rate law would be:
Rate = k[A] where k is the reaction rate constant and determined by doing experiments</span>
Answer:
a = 40 m / s²
Explanation:
This is a kinematics problem, where we must use both linear and angular and the relationship between them
we'll eat by reducing the angular velocity to units if
w = 1.0 rev / s (2pi rad / 1 rev) = 2pi rad / s
they ask us for linear acceleration, we use the relationships between linear or angular variables
a = α R
a = 20 2
a = 40 m / s²
Answer:
Because the weight depends of the gravity
Explanation:
This is because weight and mass are different, in order to better understand this problem we will apply an example with real values, which will help us to determine a person's weight.
A man has a mass of 80 [kg] on Earth when measuring his weight he realizes that it is 784.9 [N] and on the moon it is 130.8 [N]
<u>On Earth</u>
<u />
Where:
g = gravity
<u>Weight on the moon</u>
<u />
Wm = 80 * 1.635
Wm = 130.8[N]
<u>Weight on the earth</u>
<u />
We = 80 * 9.81
We = 784.8[N]
<u />
In this way we can see that the weight depends on the gravity of where the person is located.
