A uniform meter scale of weight 50gf is balanced at 30cm mark when weight of 80gf and 60gf act at 5cm and 45cm mark respectively. What force must be applied at 20cm mark to balance the scale?​

Answer» LET a wt. of 80gf be placed at a distance x from 40cm mark. CLOCK wise MOMENTS = Anticlock wise moment (80 × x) + 50 × (50 – 40) = 100 × (40 – 5) 80x +500 = 3500 80x = 3500 – 500= 3000 x= 3000/80 = 37.5cm∴ A is at 40 + 37.5 = 77.5cm

DEFINE:-• EXPLAIN NEWTON 2 LAW.•EXPLAIN NEWTON 3 LAW​

Answer»

tion:Newton's second law states that the acceleration of an object is directly related to the net FORCE and inversely related to its mass. Acceleration of an object DEPENDS on two things, force and mass.Newtons third law states that for every ACTION (force) in nature there is an equal and opposite REACTION. If object A exerts a force on object B, object B also exerts an equal and opposite force on object A.

The mass of a body is reduced to half its initial value and the velocity is increased to twice its original value. What is the new kinetic energy? ​

Answer»

Well let’s interpret this into the KINETIC Energy equation, K.E=1/2mv^2. For the first body of MASS, we will have m=4 and v=5, and the second body of mass will be m=2 and v=10. K.E1=1/2(4)(5^2), =1/2(4)(25), =1/2(100), K.E1=50 Joules of Energy. K.E2=1/2(2)(10^2), =1/2(2)(100), =1/2(200), K.E=100 Joules of Energy. As you can see, when the body of mass is halfed and its VELOCITY is doubled compared to another body of mass in motion, it’s Kinetic Energy will be doubled compared to the first body of mass in motion.

Q. 16 This statement implies that thermal equilibrium is an equivalence relation on the set of thermodynamic systems under consideration Systems are said to be in equilibrium if thesmall, random exchanges between them (eg. Brownian motion) do not lead to a net changein energy. This law is tacitly assumed in every measurement of temperature. Thus, if oneseeks to decide whether two bodies are at the same temperature, it is not necessary tobring them into contact and measure any changes of their observable properties in time.The law provides an empirical definition of temperature and justification for theconstruction of practical thermometers.Do any four questions(a) What is importance of zeroth law of Thermodynamics?(b) What do you mean by thermal equilibrium?(c) Above law is called zeroth law. Why?(d) What do you mean by absolute zero temperature?(e) Convert 100° F into °C​

A wheel of 30cm in radius rotate at the rate of 180 revolution per minute. find centripetal acceleration of a point on the edge of wheel?​

Answer»

nfo : A wheel of 30cm in radius rotate at the rate of 180 revolution per minute.To find : The centripetal acceleration of a POINT on the EDGE of wheel is ...solution : radius of wheel, r = 30 cm = 0.3 m ANGULAR velocity of wheel, ω = 180 rev/min = 180 × 2π/60 rad/s = 6π rad/s now centripetal acceleration, a = rω² = 0.3 × 6π m/s² = 1.8 × 3.14 m/s² = 5.652 m/s² Therefore the centripetal acceleration of a point on the edge of wheel is 5.652 m/s².

Torque due to electric diploe in non uniform electric field ? noawctf-rfv

Answer»

a torque and a NET forceWhen electric field is not uniform, the net force will be non-zero, there will ALSO be torque on the system.When dipole moment p is PARALLEL or anti-parallel to external field E, the net torque is zero, but there is a force on the dipole E which is not uniform. It is seen that when p is parallel to E, dipole has a net force in the direction of increasing field and when p is antiparallel to E, the net force on dipole is in the direction of decreasing field. Force depends on the ORIENTATION of dipole moment with respect to the external field.Hence, an electric dipole placed in a non-uniform electric field EXPERIENCES both a torque and a net force.

Answer»

There are ACTUALLY three, Kepler’s LAWS that is, of planetary MOTION: 1) every planet’s orbit is an ellipse with the Sun at a focus; 2) a line joining the Sun and a planet sweeps out equal areas in equal times; and 3) the square of a planet’s orbital PERIOD is proportional to the cube of the semi-major axis of its orbit. As it’s the third which is most often used, Kepler’s law usually means Kepler’s third law (of planetary motion).
