<span>So we want to know which object has a gravitational force of the greatest magnitude. Since gravitational force depends on the mass of the object, the object with the greatest mass will have the greatest magnitude of the gravitational force. In this case that is the bowling ball. </span>
Answer:
Hydrogen bond.
Explanation:
It is an intermolecular bonding interaction between two molecules of different electronegative values or bonding between lone pairs of electron rich molecules.
Hydrogen-bonding forms in liquid water as the hydrogen atoms of one water molecule are then attracted towards the oxygen atom of a neighboring water molecule resulting in a general proton shared by two lone electron pairs.
Answer:
the thickness of the mica is 6.64μm
Explanation:
By definition we know that the phase between two light waves that are traveling on different materials (in this case also two) is given by the equation
Where
L = Thickness
n = Index of refraction of each material
Our values are given as
Replacing our values at the previous equation we have
the thickness of the mica is 6.64μm
The abiotic community of the ecosystem or the nonliving objects in the earth's biosphere influences the survival, growth and development of the organism. They provide basic mmaterials to support life by the biogeochemical processes which is composed of many biological and environmental cycles which profoundly has factored the intiation and continuation of life on earth. They also provide the basic materials to support life by the undergoing process which is also initiated by the living creatures or the biotic society of the ecosystem.
Answer:
Efficiency = 10.2 %
Explanation:
Given the following data;
Mass = 70 kg
Height = 50 m
Velocity = 10 m/s
We know that acceleration due to gravity is equal to 9.8 m/s².
To find the efficiency of energy conversion from potential to kinetic;
First of all, we would determine the potential energy;
P.E = mgh
P.E = 70 * 9.8 * 50
P.E = 34300 J
For the kinetic energy;
K.E = ½mv²
K.E = ½ * 70 * 10²
K.E = 35 * 100
K.E = 3500
Therefore, Input energy, I = 34300 J
Output energy, O = 3500 J
Next, we find the efficiency;
Efficiency = O/I * 100
Substituting into the formula, we have;
Efficiency = 3500/34300 * 100
Efficiency = 0.1020 * 100
Efficiency = 10.2 %
