I cannot see anything L question Luestion
B. Decreasing surface area of a solid reactant. The more surface area showing, the quicker the reaction rate.
Answer:
Explanation:
Frequency refers to the number of occurrences of a periodic event per time and is measured in cycles/second. In this case, there is 1 cycle per 2 seconds. So the frequency is 1 cycles/2 s = 0.5 Hz.
They are chemically opposite in that the reactants of one are the products of the other. One could not exist without the other to supply the materials.
You can look up the reactants and products in any Biology textbook. also <span>In Photosynthesis carbon dioxide and energy is consumed to give sugar and Oxygen. </span>
<span>while in Respiration oxygen and sugar is consumed to give energy and carbon dioxide is produced. </span>
<span>Hence the two are opposite of each other. </span>
<span>Now, since you need oxygen to respire there must be a constant supply of oxygen and plants are the source of oxygen since they produce oxygen due to photosynthesis, similarly plants need oxygen to do photosynthesis which is produced by respiration. </span>
<span>Hence they both are dependent on each other HOPE IT HELP ;D</span>
Answer:
a) 1321.45 N
b) 1321.45 N
c) 2.66 m/s^2
d) 2.21*10^-22 m/s^2
Explanation:
Hello!
First of all, we need to remember the gravitational law:
Were
G = 6.67428*10^-11 N(m/kg)^2
m1 and m2 are the masses of the objects
r is the distance between the objects.
In the present case
m1 = earth's mass = 5.9742*10^24 kg
m2 = 497 kg
r = 1.92 earth radii = 1.92 * (6378140 m) = 1.2246*10^7 m
Replacing all these values on the gravitational law, we get:
F = 1321.45 N
a) and b)
Both bodies will feel a force with the same magnitude 1321.45 N but directed in opposite directions.
The acceleration can be calculated dividing the force by the mass of the object
c)
a_satellite = F/m_satellite = ( 1321.45 N)/(497 kg)
a_satellite = 2.66 m/s^2
d)
a_earth = F/earth's mass = (1321.45 N)/( 5.9742*10^24 kg)
a_earth = 2.21*10^-22 m/s^2
