Answer:
Explanation:
Let mass of cart be m₁ and m₂
m₁ + m₂ = 1.5 kg
At the time of release , their momentum will be conserved
m₁ v ₁ = m₂ v₂
m₁ v ₁ = (1.5 - m₁ ) x 2 v₁
m₁ = 3 - 2m₁
3m₁ = 3
m₁ = 1 kg
m₂ = .5 kg
1. LSD (or long slow distance) training, also known as a continuous training, involves performing an activity, such as jogging, cycling or swimming, nonstop for a period of time. This training is targeted for health-related improvements and is often required before engaging to more demanding, aerobic methods like fartlek. Medium-range on the other hand, is where the work period is dominated by the lactic acid energy system. This occurs either when the work period is between 10 and 60 seconds or when the work-to-rest ratio is 1:2 or 1:3. The aim of medium-interval training is to develop tolerance of lactic acid.
2. The starter phase allows the body to get used to the idea of exercise, avoid soreness and injury, and to experiment until you find the program that works best for you.

Answer:
Option (D) By observing illuminated mountain peaks in the dark portion of the moon.
Explanation:
Unlike the traditions at the time of Aristotle which considered that the celestial bodies are spherical and perfectly smooth bodies.
But based on Galileo's observations, the zone that was illuminated in the dark region of the moon near the line that separates the illuminated and the shadowy parts, known as terminator was noticed.
On the breaking of the dawn, as the sunlight hit the top of the lunar mountains it lightens up while the valleys are still dark.
