<span>The correct option is B. Regolith is a layer of loose, heterogenous material covering solid rock. It include soil, dust, broken rock and other related materials and can be found in the earth, some asteroids, mars, moon and other terestial planet. Moon regolith occurs as a mixture of powdery dust and broken rocks.</span>
Answer:20/47 meter per second
Explanation:
Mass of arrow(ma)=0.25kg
Velocity of arrow(va)=12m/s
Mass of target(mt)=6.8kg
Velocity of target(vt)=0 since target is at rest
Conservation of linear momentum says that :
maxva+mtxvt=(ma+mt)V
V=(maxva+mtxvt)/(ma+mt)
V=(0.25x12+6.8x0)/(0.25+6.8)
V=3/(7.05)
V=20/47 meter per second
Answer:
If we use the equation for the transformation of velocities for moving frames:
v' = (v - u) / (1 - u * v / c^2) where we measure the speed of v' approaching from the left where v is in a frame moving at -u towards v'
v' = (.6 c - (-.6 c)) / (1 - (-.6 c) * .6 c / c^2) = 1.2 c / (1 + .6 * .6)
or v' = 1.2 c / (1 + .36) = .88 c
v is approaching from the left at .6 c in the reference frame and the other frame approaches from the right at -.6 c with speed u (-.6 c) and we measure the speed of v as seen in the frame moving to the left
Explanation:
We know that resistance
clearly,
R∝ 1/A
Greater the area cross section area of the.
therefore,
Answer:
The required minutes is 4 minutes.
Explanation:
Blowers are very important or Crucial because it's safeguard life on boat.
Blowers are constructed so that gasoline fumes will be cleared from comparments.
It is important to operate the blower for 4 minutes before starting an engine to remove fuel vapor so as to prevent explosion because explosive gasoline's or battery fumes could be present in engine compartments which could cause explosion if it's not operated for 4 minutes before you start the engine
