1) 1.15666
2)1.07
3)1.36
Explanation:
To find the average take the vaules of the numbers and add then divide by how many numbers are in the eqation and that should give you your average.
A gamma ray is the same physical thing as a radio wave or
a light wave. All of them are traveling electric and magnetic
fields, not charged particles. The waves and rays have no charge.
Answer:
4Al + 3Mno2 --> 2Al2o3 + 3Mn
Explanation:
Al = 1 x 4 = 4
Mn = 1 x 3 = 3
O = 2 x 3 = 6
----------
Al = 2 x 2 = 4
Mn = 1 x 3 = 3
O = 2 x 3 = 6

Explanation:
Strain energy is defined as the energy stored in a body due to deformation. The strain energy per unit volume is known as strain energy density and the area under the stress-strain curve towards the point of deformation. When the applied force is released, the whole system returns to its original shape.
Answer:
38.47 m
Explanation:
To find the height of the building, we will use the following equation

Where yf is the final height, yi is the initial height, viy is the initial vertical velocity, t is the time, and a is the acceleration due to gravity.
If the brick is in flight for 3.1 s, we can say that when t = 3.1s, yf = 0 m. So, replacing
viy = (16 m/s)sin(10) = 2.78 m/s
a = -9.8 m/s²
we get

Solving for yi

Therefore, the height of the building is 38.48 m
