In my opinion,I think the answer is b.You can control variables more easily by doing different things for different purposes.
The frontal bone.
A blowout fracture is one where the orbit of the eye socket is damaged. This type of fracture is usually accompanied by double vision, depressed ocular globes and loss of feeling in the cheeks. Bones other than the frontal bone which are responsible for the structure of the eye socket are the zygomatic bone and the maxilla.
<u>Given</u><u>:</u>
- initial velocity, u = 200 m/s
- Final velocity, v = 300 m/s
<u>To</u><u> </u><u>be</u><u> </u><u>calculated</u><u>:</u>
Calculate the acceleration of given object ?
<u>Formula</u><u> </u><u>used</u><u>:</u>
Acceleration = v - u / t
<u>Solution</u><u>:</u>
We know that,
Acceleration = v - u / t
☆ Substituting the values in the above formula,we get
Acceleration ⇒ 300 - 200 / 20
⇒ 100/20
⇒ 5 m/s²
Answer: B
Explanation: A sphere is a perfectly round geometrical object in three-dimensional space that is the surface of a completely round ball (viz., analogous to the circular objects in two dimensions, where a "circle" circumscribes its "disk"). Like a circle in a two-dimensional space, a sphere is defined mathematically ... This distance r is the radius of the ball, which is made up from all points.
Answer:
a) The number density is 3.623 × 10⁻³ 
The mass of the atmosphere is 1.3 × 10²²Kg
b) The pressure is 10⁻²⁰ Millimeter of mercury
c) The mass mixing ratio is 0.0107
The partial pressure of ethane is 0.01114 Pa
Yes it is condensable because it boiling point is -88.5 C which is equivalent to 184.5 K i.e is adding 273 to -88.5C and the temperature of the atmosphere is 37 K.
