French revolution started in 1789. The series of events started by the middle class shook the upper classes. The people revolted against the cruel regime of monarchy. This revolution put forward the ideas of liberty, fraternity, and equality. The revolution began on 14th July, 1789 with the storming of the fortress-prison, the Bastille. The Bastille was hated by all, because it stood for the despotic power of the king. The fortress was demolished.

Striated

The cells are long, cylindrical, unbranched and multinucleate (having many nuclei).
These muscles are called voluntary muscles, because they show movement when we want.
These muscles are also called skeletal muscles.
They are mostly attached to bones and help in body movement.
These muscles show alternate light and dark bands or striations when observed under the microscope, due to this reason they are also called striated muscles.

Smooth/unstriated

The cells are long with pointed ends (spindle-shaped) and uninucleate (having a single nucleus).
They are also called unstriated muscles.
They are under the control of involuntary muscles.
The movement of food in the alimentary canal or the contraction and relaxation of blood vessels are involuntary movements.
They are also found in the iris of the eye, in ureters and in the bronchi of the lungs.

Cardiac

The muscles of the heart are involuntary in nature and called cardiac muscles.
The cells are cylindrical in shape, branched and uninucleate.
The heart muscles show rhythmic contraction and relaxation throughout life.

It refers to the situation of soil with water. Soil may be regarded as waterlogged when it is nearly saturated with water much of the time such that its air phase is restricted and anaerobic condition prevails in extreme cases of prolonged waterlogging anaerobiosis occurs the roots mesophyte suffer and the subsurface reducing atmosphere leads to process as denitrification, methanogenesis and the reduction of iron and manganese oxide

Sohil M 7 years, 4 months ago

Two nuclides are isotones if they have the same neutron number N, but different proton number Z. For example, boron-12 and carbon-13 nuclei both contain 7 neutrons, and so are isotones. Similarly, ³⁶S, ³⁷Cl, ³⁸Ar, ³⁹K, and ⁴⁰Ca nuclei are all isotones of 20 because they all contain 20 neutrons.

Palak ?? 7 years, 4 months ago

Work is said to be done if some force is applied and displacement is produced due to that force,if the angle between the direction of force applied and direction and direction of displacement produced is not right angle....

1Thank You

Aadit Pandey 7 years, 4 months ago

We say it when a force is applied on an object which gets displaced with the effect of force exerted.therefore W=F×D

1Thank You

Yogita Ingle 7 years, 4 months ago

Work is said to be done by a force acting on the object when the object is displaced along the direction of force. For example,
(i) A girl pulls a trolley and the trolley moves through a distance. The girl has exerted a force on the trolley and it is displaced along the direction of force. Therefore, work is done.
(ii) Lift a book through a height. To do this, you must apply a force. The book rises up. There is a force applied on the book and the book has moved up in the direction of force. Hence, work is done.
Thus, following two conditions need to be satisfied for work to be done:
(i) a force should act on an object, and
(ii) the object must be displaced along the direction of force.

The movement of the medium is of the same direction of the wave	The movement of the medium is perpendicular to the direction of wave
It acts in one dimension	It acts in two dimension
The wave cannot be polarized or aligned	The wave can be polarized or aligned
This wave can be produced in any medium such as gas, liquid or solid	This wave can be produced in solid and liquid’s surface
Earthquake P wave is an example	Earthquake S wave is an example
It is made of refractions and compressions	It is made of troughs and crests
