Answer:

10 m²

Explanation:

PRESSURE = FORCE / Area

Area = Force / Pressure

= 100000 N / 10000 PA

The ELECTROMAGNET USES this principle. An electromagnet can be defined as a magnet which functions on electricity. Unlike a permanent magnet, the strength of an electromagnet can be changed by changing the AMOUNT of ELECTRIC current that flows through it.

ANSWER:

Energy of INCIDENT LIGHT:

E = hclamda

E = 6.6×10^-343×108200×10^-9

E = 9.9×10^-20J

Work Function:

W = hclamda×o

W = 6.6×10^-343×108250×10^-9

W = 7.92×10^-20J

Energy of the EMITTED electrons:

K.E = E-W

K.E = 9.9×10^-20J - 7.92×10^-20J

K.E = 19.8×10^-20J

Answer:

measurement of a quantity, like temperature, or mass. A vector has more than one number associated with it. A SIMPLE example is velocity. It has a MAGNITUDE, called SPEED, as well as a direction, like North or Southwest or 10 degrees west of North. You can have more that two numbers associated with a vector. For example you can add a height dimension to velocity and say, for example, ' I am going uphill at a 5 degree slope in the NORTHEAST direction'. Vectors are frequently BROKEN down into their components along an orthogonal coordinate system, like the x and y axes. So you can say the y-component of my speed is 3 km/sec and the x-component of my speed is 4 km/sec. The magnitude, or speed is the square root of the sum of the individual components, 5 in this case. The direction with respect to the x-axis would be given by the arctangent of Vy / Vx or 36.9 degrees.

Explanation:

The ANGULAR dispersion is defined as angle between the two extreme colours of light . DISPERSIVE power of a prism is defined as the RATIO of angular dispersion to the DEVIATION of MEAN colour.

Explanation:

The Statement of PARALLELOGRAM law of vector ADDITION is, If two vectors are considered to be the adjacent SIDES of a parallelogram, then the resultant of two vectors is given by the vector that is a diagonal passing through the point of contact of two vectors.

→ The transfer of pollen grains from the anther to the STIGMA is called pollination.

It is of two types :

Self pollination : The transfer poem grains from the anther of flower to the stigma of same flower or of ANOTHER flower BORN on same PLANT is called self pollination.

CROSS pollination : The transfer of pollen grains from one plant to the stigma of flower of another plant is called cross pollination.

Stable state corresponds to MINIMUM potential energy. This is POSSIBLE when X = 0. So, option (1) should be the answer.

<P>Answer:

PQ

Explanation:

If dot product of two vectors is 0 it MEANS the vectors are perpendicular to each other (90 DEGREES)

So,

|p × Q| = pqSin∅

= pqSin90

Factors that have to be mentioned while describing motion of an object are as follows:

• The reference frame w.r.t which motion is taking place have to be kept in MIND. For example ; ACCORDING to a person on the ground a moving train is in motion , but according to a passenger on that same train , the moving train is stationary. Hence , pointing out the reference frame is very important.

• The DIRECTION of motion must be mentioned with respect to the 3D co-ordinate axes.

• The Velocity and acceleration of the object must also be described with both MAGNITUDE as WELL as directions with respect to the 3D co-ordinate axes.

Hope It Helps.

Answer:

Option (3) 0.8 m

Explanation:

The horizontal DISTANCE travelled by the block of MASS M = 4 m

Since there is no force in the horizontal direction

Therefore, the MOMENTUM in the horizontal direction will be conserved

If the velocities of block and the wedge in the horizontal direction are

and then

if the distance travelled in the horizontal direction by the block and the wedge are and then

If the wedge travels distance x then

The block has a displacement of 4 m with RESPECT to the wedge but the wedge also has a displacement of x m in the same time

Therefore, displacement of block with respect to the earth =

Thus,

m

Thus, the wedge travels a distance of 0.8 m

Answer: F=ma

Explanation:

For a car to MOVE, there must be friction between the wheels and the ground. The wheels EXERT a FORCE on the ground because they are spinning, and the ground exerts a REACTION force on the wheels. It is this force which pushes the car forward. So THANK Newton's law of action and reaction every time you drive somewhere!

ANSWER:

विस्थापन (अंग्रेज़ी: DISPLACEMENT) एक सदिश राशि है। जब कोई वस्तु एक बिन्दु P से दूसरे बिन्दु Q तक किसी भी पथ से होते हुए गति करती है तो इस विस्थापन [1] का परिमाण उन दो बिन्दुओं के मध्य की निम्नतम दूरी होगी तथा विस्थापन की दिशा, रेखा PQ की दिशा में (P से Q की तरफ) होगी।[2] विस्थापन को s से दर्शाते हैं। विस्थापन का परिमाण काल्पनिक सीधे पथ की लम्बाई है, अतः यह कण द्वारा तय की गई कुल दूरी से अलग हो सकता है। जब कोई वस्तु p बिन्दु से q बिन्दु तक जाती है और वापस पुनः p बिन्दु आ जाती हैं, तब विस्थापन शून्य होगा, जबकि चली गयी दूरी शून्य नहीं होगी।

Answer:

A voltmeter, ALSO known as a VOLTAGE METER, is an instrument used for measuring the potential difference, or voltage, between two points in an ELECTRICAL or electronic circuit. ... A basic analog voltmeter consists of a sensitive galvanometer (CURRENT meter) in series with a high resistance.

UNIFORM motion

Explanation:

• If the distance traveled by an object is  DIRECTLY proportional to time, then we can SAY  that the object is moving with uniform speed.
• It is said that the object is moving under uniform motion.
• The slope of position time GRAPH GIVES velocity of an object.
• It is given by :

x is displacement
