The surface tension of isopropyl alcohol in air has a value of 22.39 units and the surface tension of water in air is 72.86 unit
1 answer:
Answer:
The answer is "Option B and Option D"
Explanation:
Isopropyl alcohol has an air pressure of 22,39 units with such a water contact angle of 72,86 units.
The melting points of Isopropyl alcohol are higher than water because of the weaker forces between the previously studied.
The flatter meniscus is indeed the isopropyl ethanol so because forces between the particles are smaller.

Given that,
Mass of the cart,
Mass of the cart 2,
Final speed of cart 2,
Final speed of cart 1 is 0 as it comes to rest.
Let us assume that the initial velocity of the cart 2 is 0. So using the conservation of linear momentum as :
So, the initial velocity of the 1.0-kg cart is 0.9 m/s.
