Answer:
It is possible to statically charge objects by rubbing it against carpet fibers, but I'm not sure if that was in the article that you read.
Explanation:
Static charge can build up via carpet fibers.
Answer:
For example: Freezing, boiling, are physical
Explanation:
Answer:
Kinetic Energy = 0
Explanation:
No matter if energy is totally conserved during the fall or when it hits the ground, the kinetic energy of the silver sphere will be zero because the velocity component in 
becomes zero, the over all energy becomes zero.
Answer:
Explanation:
Apparent frequency that is received to the speeder is given as
here we know that
now we have
now the frequency that is received back from the speeder is given as
So difference is the frequency is given as
The surface area of the smaller pyramid is determined as 42.7 cm².
<h3>
Area of pyramids</h3>
The base area of the two similar pyramid is given as follows;
Base area of large pyramid = 16 cm²
Base area of smaller pyramid = 12.2 cm²
<h3>
Surface area of the similar pyramids</h3>
The surface area of the smaller pyramid is calculated as follows;
s₁/b₁ = s₂/b₂
s₁/12.2 = 56/16
s₁ = 42.7 cm²
Thus, the surface area of the smaller pyramid is determined as 42.7 cm².
