Oxidation number of carbon in CH3CH2OH

Presence of mesoglea is the feature of triplobastic animals

Q.4

A particle which show SHM , then accelaration of particle is uniform

Q. 1

Circular motion is the example of preodic motion

Internal Forces acting in a system of particle can change--

1. A combination of 2 SHM with arbitrary amplitudes and phases must be periodic.
2. If a narrow sound pulse is sent across a medium and the pulse rate is 1 after every 10 s then the frequency produced is 0.1 Hz.

Hemichordata are non-chordate animals

X = The arm of Ophiura is thicker than the arm of Asterias

Y = Antedon found in fresh water

1. A solid is floating in a liquid at a certain temperature. When temperature is increased the new buoyant force remains unchanged.
2. As the Temperature of water increases from 0°C to 4°C the coefficient of volumetric expansion also increases

The electronagativity of an element is low . The bond formed b/w the atoms =

Initially a solid is completely immersed in water at 1°C and the coefficient of its volumetric expansion is equal in magnitude with the coefficient of volumetric expansion of water. When the temperature is increased to 3.5°C- [ Fb- buoyancy force ]

X = PH₃ acts as a lewis base

Y = Covalancy of F is 03 in FCl₃

Heat is being supplied at a constant rate to a sphere of ice which is melting at the rate of 0.1 gram / sec

Now it melts completely in 100 sec . The rate of rise of temperature will be =

The endomembrane system of a eukaryotic cell does not include:

1. Endoplasmic reticulum 2. Lysosome 3. Vacuole 4. Peroxisome

What is false about - " Alstonia " ?

What is not true for genetic code?

The organisms which cause diseases in plants and animals are called :-

X = Couple do not use device in natural methods for conception

Y = In natural method , couple mainly avoid the sexual intercourse from day 10 to 17 of menstrual cycle

A. 2 identical spheres are placed 1m apart. A point object placed at midpoint along line joining their centres will be in unstable equilibrium
B. If 0 of potential energy is at ♾️ then total energy of orbiting satellite is negative of potential energy
