1.) Product is a solid
2.) Product has flat slides
3.) Flat sides meet at sharp edges and corners
The product would be a crystal, or it would be a type of product in a crystal structure.
Answer:
To save the unnecessary bills and carbon emissions.
Explanation:
Energy efficiency is important to society in the following ways:
1. It saves the unnecessary bills as buildings who are using energy efficiently have less demands.
2. Saving energy for the future generations as we know low demand would save the sources.
3. Energy efficiency is also important to society in environmental ways at efficient energy means low carbon emissions.
Answer:
The acceleration at lowest point is 19.62 m/s^2
Explanation:
Conservation of energy is an concept in which it is stated that the energy of an isolated object remains the same. Energy changes from one form to another.
Lets Assume
Constant of string is K
By using the conservation of energy we will have the following equation
1/2 x 80^2 x K = m x 9.81 x 120
3200 K = 1177.2 m
K = 1177.2 m / 3200
K = 0.368 m
At the lowest point we will have
a = ( K x X - m x g ) / m
a = ( 0.368 m x 80 - m x 9.81 ) / m
a = 19.62 m / s^2
So, the acceleration at lowest point is 19.62 m/s^2

Answer:
∑Fy = 0, because there is no movement, N = m*g*cos (omega)
Explanation:
We can solve this problem with the help of a free body diagram where we show the respective forces in each one of the axes, y & x. The free-body diagram and the equations are in the image attached.
If the product of mass by acceleration is zero, we must clear the normal force of the equation obtained. The acceleration is equal to zero because there is no movement on the Y-axis.
