B. Troposphere, stratosphere, mesosphere, thermosphere
Answer:
The average atomic mass is 86.565
Explanation:
An element's average atomic mass is the sum of the products of the masses of the isotopes of the element and their percentage abundance divided by 100
The average atomic mass of the Element X is given as follows;
Isotope type 1 (85.91) ×
Isotope
Abundance (%) Mass /100 Portion of average mass
Type 1
67.25 × 85.91 ÷ 100 57.774475
Type 2
32.75 × 87.91 ÷ 100 28.790525
Average atomic mass = 86.565
The average atomic mass = 86.565.
Answer:
physical change. 95%Sure 5% doubtful.
The rate of change of B is twice that of A, so:
rate of change of B = 2 x -0.1
rate of change of B = -0.2 M/s
Kinetic energy is associated with the motion of an object.
Since the object is at rest on the ground, its velocity is zero.
Since kinetic energy is directly proportional to the square of velocity, kinetic energy of the ball on the ground is zero.
