Okay it would be really heplful if there was a figure present, now its not clear that where the capacitor (2C) is connected ? is it parallel with the R+C combination or just with C ?
still im going to assume that 2C is being connected with C in parallel
so
Answer:
A state of rest or balance due to the equal action of opposing forces.
Answer:
Explanation:
Let the time required for acceleration a₁ and deceleration a₂ be t₁ and t₂ .
Since final velocity during acceleration and initial velocity during deceleration are same
a₁ t₁ = a₂ t₂
5t₁ = 2 t₂ ------------------------------------------ ( 1 )
Distance travelled during acceleration = 1/2 a₁t₁²
= 1/2 x 5 x t₁² = 2.5 t₁²
Distance travelled during deceleration = 1/2 a₂t₂²
= 1/2 x 2 x t₂² = t₂²
Total distance travelled = 2 miles = 2 x 1760 x 3 ft = 10560
2.5 t₁² + t₂² = 10560
2.5 ( 2t₂ / 5 )² + t₂² = 10560
.4 t₂² + t₂² = 10560
1.4 t₂² = 10560
t₂ = 86.85 s
t₁ = 2t₂ / 5 = 34.75 s
t₁ + t₂ = 121.6 = 122 s
Total time taken = 122 s .
maximum velocity = a₁t₁
= 5 x 34.75 = 173.75 = 174 m/s .
Answer:
A leaf is falling from the tree.
Explanation:
If motion is in only one direction(x-direction) then it is know as one directional motion.
If motion is in only two direction (x and y directions) then it is know as two directional motion.
If motion is in only three direction (x , y and z directions) then it is know as three directional motion.
A bird is flying in the air -This is three directional motion.
A leaf is falling from the tree - This is two directional motion.
A train is running on track - This is one directional motion
A lady is crawling on the surface of the ball - This is three directional motion.
Therefore the answer is ---
A leaf is falling from the tree.
