Explanation:
Cells are divided by the reproductive means in unicellular organisms; whereas in multicellular organism they are the means for tissue development and maintenance in multicellular organisms. In adults, tissue renewal rather than development is the most common cell division in which several forms of cells are constantly replaced.
You can identify by:
a. boiling point
c. density.
To solve this problem we will apply the concepts related to voltage as a dependent expression of the distance of the bodies, the Coulomb constant and the load of the bodies. In turn, we will apply the concepts related to energy conservation for which we can find the speed of this
Here,
k = Coulomb's constant
q = Charge
r = Distance to the center point between the charge
From each object the potential will be
Replacing the values we have that
Now the potential two is when there is a difference at the distance of 0.1 from the second charge and the first charge is 0.1 from the other charge, then,
Applying the energy conservation equations we will have that the kinetic energy is equal to the electric energy, that is to say
Here
m = mass
v = Velocity
q = Charge
V = Voltage
Rearranging to find the velocity
Replacing,
Therefore the speed final velocity of the electron when it is 10.0 cm from charge 1 is
Given that,
Mass of magnesium, m = 2 kg
Heat added to it, Q = 8160 J
Increase in temperature,
To find,
The specific heat of magnesium.
Solution,
Th formula that is used to find the heat required to raise the temperature in terms of specific heat is given by :
So, the specific heat of magnesium is .
To solve this problem we will apply the definitions given in Newtonian theory about the Force of gravity, and the Force caused by weight. Both will be defined below, and in equal equilibrium condition to clear the variable concerning acceleration due to gravity. Finally, with the values provided in the statement, it will be replaced.
The equation for the gravitational force between the Earth and the object on the surface of the Earth is
Where,
G = Universal gravitational constant
= Mass of Earth
= Distance between object and center of earth
= Mass of Object
The equation for the gravitational pulling force on the object due to gravitational acceleration is
Equation the two expression we have
This the acceleration due to gravity which is composite constant.
Replacing with our values we have then
The value of composite constant is . Here, the composite constant is nothing but the acceleration due to gravity which is constant always.
