Answer:
L = m v r (The momentum remains constant)
Explanation:
Even in an ellipsoidal orbit, the law of conservation of angular momentum always apply. When the plant approached the perihelion, the radius of the orbit decreases and the speed of the star increases to conserve the momentum. Similarly, when the planet approaches the aphelion, the speed of the star decreases as the radius increases to conserve the momentum. So, the momentum at a particular instant can be calculated by L = m v r
A piece of wood is has a density of 0.6 g/cm3. when dipped in olive oil of density 0.8 g/cm3, 0.75 fractions of the wood is submerged inside the oil.
Fractions describe any number of parts of a whole, or more generally equal parts.In everyday English, fractions describe how many parts of a particular size there are. 8, 3/4.
In mathematics, fractions are used to represent proportions/parts of a whole. represent the same part of the whole. A fraction has two parts, a numerator and a denominator. The top number is called the numerator and the bottom number is called the denominator. A fraction is a part of a whole number and a way of dividing a number into equal parts. It is described as the number of equal parts counted (called the numerator) to the number of whole parts called the denominator. These numbers are separated by dashes.

The amount of heat will be equal to Lm.
Where L is the latent heat of fusion and m is mass of the ice.
Latent heat of ice = 80cal/g.
So the amount of heat required here will be 35× 80cal
= 2,800 cal.
"1 watt" means 1 joule of energy per second.
75 W means 75 joules/sec .
Energy = (75 Joule/sec) x (12 min) x (60 sec/min)
Energy = (75 x 12 x 60) (Joule-<em>min-sec</em> / <em>sec-min</em>)
<em>Energy = 54,000 Joules</em>
