Its VENUS because the planet is basicily a hot planet
Answer:
Ari catches up to Amanda at 19.3 meters
Explanation:
We have given Ari is swimming a 25-meter race.
It is given that after swimming 6 meters she catches up to Amanda in a ratio of 7:3 from the 6-meter mark.
So ,The distance between 6 meters and 25 meters = 25-6 =19 meters
It is given that she catched Amanda in ratio 7:3
So, she catched her at of the distance
So, the distance at which she catched Amanda
Ari catches 13.3 metres from 6 m marks
So the total distance = 13.33+6 =19.33 meters
So Ari catches up to Amanda at a distance of 19.33 meters
Impulse = Ft = Δmv, where F is the average force, t is time, m is mass and v is velocity.
Δmv = m(v₂ - v₁) = 0.2 * (3 - (-4)) = 0.2 * 7 = 1.4
Solve for F.
The work energy Mark spent to move the car is
(force) x (distance)
= (140 Newtons) x (140 meters) = 19,600 Joules .
The car moves with constant speed. That tells us that its
acceleration is zero, so the NET force on the car is also zero.
The friction force must be equal to Mark's pushing force, in
the opposite direction, and friction does as much work on the
car as Mark does . . . 19,600 Joules. The work done by the
friction force shows up as heat.
The particles can undergo small oscillations around x₂.
The given parameters;
- <em>initial energy of the particles = E₁</em>
- <em>final energy of the particles, E₂ = 0.33E₁</em>
The movement of the particles depends on the kinetic energy of the particles.
When kinetic energy of the particles is 100%, the particles can oscillate from x₁ to x₅.
However, when the total energy of this particles is reduced to one-third (¹/₃) or 33% of the initial energy of the particle, the oscillation of the particles will be reduced.
- The maximum position the particle can oscillate is x₅
- The half position the particles can oscillate is x₃
Since 33% is less than the half of the energy of the particle, the particle will oscillate between x₁ and x₂.
Thus, we can conclude that the particles can undergo small oscillations around x₂.
