Answer:
Pressure,
Explanation:
Given that,
Area of the heel,
Mass of the woman, m = 61.4 kg
To find,
Pressure on the heel.
Solution,
The pressure acting on the heel is given by the net force acting on the box per unit area. Its formula is given by :
So, the pressure exerted by the heel of the woman is . Hence, this is the required solution.
Answer:
kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
Explanation:
Answer:
Explanation:
We can use the following kinematics equations to solve this problem:
.
Using the first one to solve for acceleration:
.
Now we can use the second equation to solve for the distance travelled by the airplane:
(three significant figures).
Explanation:
Another name of covalent bonds is molecular bonds. Covalent compounds are formed by covalent bonds. The bonds in which atoms share one of more valance electrons are termed as covalent bonds. These types of bonds are in Liquid or gaseous State.
For example, methane is a covalent compound that is formed by the sharing of electrons between carbon and hydrogen atoms. Hence, Covalent compounds are usually described as the sharing of electrons between carbon atoms
