Answer:
261 million km
Explanation:
Venus has an almost perfectly circular orbit with 0.007 eccentricity. Earth however has an elliptical orbit with 0.016 eccentricity. Distance of Earth from Venus at its farthest is 261 million km. So, the difference in the farthest and closest distance is very high almost 220 million km. At the farthest Venus is 108,939,000 km from the sun and 107,477,000 km at its closest from the Sun.
Answer:
Speed of the ball in position D
<u>Explanation:</u>
Given:
Position of B=11.3
Position of D=1.9
Velocity of B=6.2
To Find:
Velocity of D
Solution:
According to the formula, Velocity is given as
=Velocity of B
=Velocity of D
g=acceleration due to gravity=9.8 m/s^2
=Change in position of B and D
Substitute the all values in the above equation we get
Result :
The velocity of D is
Answer:
That's DNA
Explanation:
DNA(Deoxyribonucleic acid) is the building blocks of life, the Legos for genetically complex life if you will. All living things have DNA, it is the instruction that that organism must follow to specify what exact traits it'll have, For example, I have Blue eyes because Blue eyes is apart of my DNA. The DNA told my body that I was gonna have blue eyes before I was born.
Answer:
a) 7200 ft/s²
b) 140 ft
c) 3.7 s
Explanation:
(a) Average acceleration is the change in velocity over change in time.
a_avg = Δv / Δt
We need to find what velocity the puck reached after it was hit by the hockey player.
We know it reached 40 ft/s after traveling 90 feet over rough ice at an acceleration of -20 ft/s². Therefore:
v² = v₀² + 2a(x − x₀)
(40 ft/s)² = v₀² + 2(-20 ft/s²)(100 ft − 10 ft)
v₀² = 5200 ft²/s²
v₀ = 20√13 ft/s
So the average acceleration impacted to the puck as it is struck is:
a_avg = (20√13 ft/s − 0 ft/s) / (0.01 s)
a_avg = 2000√13 ft/s²
a_avg ≈ 7200 ft/s²
(b) The distance the puck travels before stopping is:
v² = v₀² + 2a(x − x₀)
(0 ft/s)² = (5200 ft²/s²) + 2(-20 ft/s²)(x − 10 ft)
x = 140 ft
(c) The time the puck takes to travel 10 ft without friction is:
t = (10 ft) / (20√13 ft/s)
t = (√13)/26 s
The time the puck travels over the rough ice is:
v = at + v₀
(0 ft/s) = (-20 ft/s²) t + (20√13 ft/s)
t = √13 s
So the total time is:
t = (√13)/26 s + √13 s
t = (27√13)/26 s
t ≈ 3.7 s
The appropriate response is the last one. The electrical fascination in the North Pole of the magnet. The essential standard for all electric engines is that when a current conveying conduit cuts an attractive field, a mechanical compel is created on the transmitter relative to the rate of progress in the attractive field which makes the conveyor move.
