C standards are based on observable, reproducible natural phenomena.
Answer:
Distance piston B = 3 [in]
Explanation:
This problem can be solved using the pascal principle, which is applied for both pressures and volumes. In this case we use the definition of volumes, which says that the volume displaced fluid on one side of the Pistons should be equal to the volume displaced on the other side of the piston.
We know that the volume is equal to the product of an area by a length

Answer:
The bike traveled 31.3 meters during this period
Explanation:
A speed bike tops a hill at 3.50 m/s and accelerates steadily down the
hill until reaching a speed of 11.4 m/s after 4.20 seconds
→ The initial speed u = 3.5 m/s
→ The final speed v = 11.4 m/s
→ The time of acceleration t = 4.2 seconds
→ a = 
Substitute the values above in the rule to find the acceleration a
→ a = 
= 1.88 m/s²
We need to find the distance that the bike traveled during the
acceleration
→ v² = u² + 2 a s, where s is the distance
→ (11.4)² = (3.5)² + 2 (1.88)(s)
→ 129.96 = 12.25 + 3.76 s
Subtract 12.25 from both sides
→ 117.71 = 3.76 s
Divide both sides by 3.76
→ s = 31.3 meters
<em>The bike traveled 31.3 meters during this period</em>
<h2><u>Question</u> :</h2>
When an athlete perspires after running
- Evaporation occurs and helps to cool the body.
- Convection cools the body.
- The body absorbs cold from the surrounding air.
- Heat is conducted away from the body.
<h2><u>Answer</u> :</h2>
When an athlete perspires after running evaporation occurs and helps to cool the body.
Correct option is A.
<h2><u>Explanation</u> :</h2>
When an athlete perspires after running then sweat evaporates and we know that evaporation causes cooling as evaporation requires heat energy. The required heat energy is taken away by the molecules of sweat when they convert from liquid into gas, and this causes cooling on the surface of body. That's why it helps to cool the body.
A visible white and red light indicate a second craft is coming from the starboard (right) side.
<h3>What is a navigation light?</h3>
A navigation light often referred to as a running light or position light, is a source of illumination aboard a ship, plane, or spacecraft that provides information about the location, course, or condition of the vehicle. Red and green navigation lights help with traffic control by indicating the orientation of the craft.
All navigation light systems typically comprise one or more white lights as well as red and green sidelights that designate the boat's port and starboard sides.
Having a flashlight on board is also essential since you never know when a navigation light may go out.
The typical navigational lights:
SidelightsSternlightMasthead lampoverall white lighting
Sidelights: Because they are visible to other vessels approaching from the side or head-on, these red and green lights are sometimes known as combo lights. The port (left) and starboard (right) sides of a ship are indicated by the red and green lights, respectively.
sternlight: Only from behind or almost behind the ship can one see the sternlight.
