57.27 degree

Gaurav Seth 3 years, 9 months ago

The degree measure of 1 radian (taking π = (22 / 7)) is  57°16’22” (approx.)

π = radian = 180°

∴ 1 radian = <center>180°</center>  
π

 

= <center>180 × 7°</center>  
22

 

=   <center>630</center> = 57 <center>3</center> °
11 11

 

= 57°   <center>3</center> × 60" = 57° <center>180'</center>  
11 11

 

= 57°16' <center>4</center> × 60" = 57°16'22"

Newton’s laws of motion imply the relationship between an object’s motion and the forces acting on it. In the first law, we come to understand that an object will not change its motion unless a force acts on it. The second law states that the force on an object is equal to its mass times its acceleration. And, finally, the third law states that for every action, there is an equal and opposite reaction.

What are some daily life examples of Newton’s 1st, 2nd and 3rd laws of motion?

Riding a bicycle is a good example of Newton’s 2nd law. In this example, the bicycle is the mass. The leg muscles pushing on the pedals of the bicycle is the force.

  • The motion of a ball falling through the atmosphere, or a model rocket being launched up into the atmosphere are both excellent examples of Newton’s 1st law.
  • You hit a wall with a certain amount of force, and the wall returns that same amount of force. This is an example of Newton’s 3rd law.

Velocity is a time rate of displacement

Nishant Sharma 3 years, 4 months ago

Velocity a type of tensor to be accurate tensor of rank 1 is called as vector. I guess you know about tensor

Yogita Ingle 3 years, 11 months ago

  • Velocity: Velocity is the speed of an object moving in a definite direction.
  • The SI unit of velocity is also metre per second.
  • Velocity is a vector quantity; it has both magnitude and direction.

C=e°A/(d-t+t/k) Where d=distance b/w plates t=thickness of dielectric k= dielectric constant

Gaurav Seth 3 years, 11 months ago

Consider a parallel plate capacitor without any dielectric medium (vacuum) between the plates. Let A be the area of the plates and d be the plate separation. The two plates have charges Q and – Q. Since d is much smaller than the linear dimension of the plates (d2 << A), 

Plate 1 has surface charge density σ = Q/A and plate 2 has a surface charge density – σ. Using earlier result of the electric field in different regions is: Outer region I (region above the plate 1), 

Outer region II (region below the plate 2), 

In the inner region between the plates 1 and 2, the electric fields due to the two charged plates add up, giving 

The direction of electric field is from the positive to the negative plate. Thus, the electric field is localised between the two plates and is uniform throughout. For plates with finite area, this will not be true near the outer boundaries of the plates. The field lines bend outward at the edges – an effect called ‘fringing of the field’. Hence σ will not be strictly uniform on the entire plate. 

However, for d2 << A, these effects can be ignored in the regions sufficiently far from the edges, and the field there is given by Eq. (1). Now for uniform electric field, potential difference is simply the electric field times the distance between the plates, that is,

The capacitance C of the parallel plate capacitor is then 

which, as expected, depends only on the geometry of the system.

Dimensional of a physical quality are powers to which base qualities are raised to represent that quality.

Gaurav Seth 4 years ago

Dimensions of a physical quantity are powers (exponents) to which base quantities are raised to represent that quantity. They are represented by square brackets around the quantity.

  • Dimensions of the 7 base quantities are – Length [L], Mass [M], time [T], electric current [A], thermodynamic temperature [K], luminous intensity [cd] and amount of substance [mol].

Force = Mass x Acceleration = [M][L]/[T]2 = [MLT-2]

The right hand screw rule can be used when a direction must be determined based upon a rotational direction, or vice versa. It is best illustrated using a diagram. The axis is 'grasped' in the right hand, the fingers curl round in the direction of positive rotation and the thumb is orientated in the positive direction.

The current flowing through the conducter is directly proportional to the potential difference across the ends of the conductor provided temperature and others physical quantities remain same..V=IR

Yogita Ingle 4 years, 3 months ago

Ohm’s Law

  • Ohm’s law is named after the scientist Ohm who gave this law.
  • According to the Ohm’s law current flowing through a conductor is directly ∝ to the potential difference applied between the ends of the conductor.
  • This means if the potential difference applied at the ends increases then the current flowing through the conductor also increases and vice-versa.
  • Mathematically
    • Current flowing through the conductor I ∝ V where V is the potential difference applied at the ends of the conductor.
    • Or I=(constant) V where constant = 1/R where R =resistance of the conductor
    • => I=(1/R)V
    • =>V=IR

Relative error is defined as the ratio of the absolute error of the measurement to the actual measurement. Using this method we can determine the magnitude of the absolute error in terms of the actual size of the measurement. If the true measurement of the object is not known, then the relative error can be found using the measured value. Relative error gives an indication of how good a measurement is relative to the size of the object being measured.

If x is the actual value of a quantity, x0 is the measured value of the quantity and Δx is the absolute error, then the relative error can be measured using the below formula.

Relative error = (x0-x)/x = (Δx)/x

An important note that relative errors are dimensionless. When writing relative errors it is usual to multiply the fractional error by 100 and express it as a percentage.
