Degrees to Radian Formula
To convert degree to radian, we can use the same formula as given in the above section.
Degree x π/180 = Radian
Let us see some examples:
Example: Convert 15 degrees to radians.
Solution: Using the formula,
15 x π/180 = π/12
Example: Convert 330 degrees to radians.
Solution: Using the formula,
330 x π/180 = 11π/6
<th>Angle in Degrees</th> <th>Angle in Radians</th>| 0° | 0 |
| 30° | π/6 = 0.524Rad |
| 45° | π/4 = 0.785Rad |
| 60° | π/3 = 1.047Rad |
| 90° | π/2 = 1.571Rad |

The initial velocity travelled is 625m
The accleration is α=10m/s2
The time is t=5s
Apply the equation of motion
v=u+at
The velocity is v=0+10.5=50m/s.
The distance travelled in the first 5s is
s=ut+ 1/2 at2 = 0.5+ 1/2.10.52=125m
Thedistancetravelledinthefollowing10s is
s1=ut1=50.10=500m
Thetotaldistancetravelledisd= s+s1 = 125+500=625m

Let x be the distance travelled in time t. Then,
x∝t2 (given)
x=kt2 (Here, k = constant of proportionality)
We know that velocity is given
v=dx/dt=2kt
and acceleration is given by
a=dv/dt=2k (constant)
Thus, the body has uniform accelerated motion.

In the field of physics, the Candela (often denoted by the symbol ‘cd’) can be defined as the unit of luminous intensity – a measure of the wavelength weighted power emitted by a source of light. As per the International System of Units (often abbreviated to SI), the Candela is a base unit which can be defined by taking the fixed value (in numerical terms) of the luminous efficacy of the monochromatic radiation having a frequency of 540 * 1012 Hertz. Alternately, it can be described as the luminous power corresponding to one unit solid angle that is emitted by a point source of light (in a given direction). The SI base unit for luminous intensity has Latin roots – the word ‘candela’ translates to ‘candle’ in the Latin language. It can be noted that the luminous intensity associated with the light emitted by a common wax candle is roughly equal to one candela.

Let us suppose the first force to be 3x and the other force to be 5x.
Now resultant can be given by sqrt [a*a + b*b + 2abcos(angle between a and b)]
so in this case the resutant becomes = sqrt [9x*x + 25x*x + 15x*x] = 35 N it is given
hence, 7x = 35
hence x = 5
so the values of the forces are 15N and 25N

We all know that for a given volume of a liquid, a sphere has the least surface area. Also, the more the surface area of an object, the more is its surface energy.
Now, to remain in stable equilibrium, a body always tries to minimize its surface energy. Therefore it tries to reduce its surface area and hence acquires a spherical shape.
All this phenomena is because of the presence of surface tension of a fluid.

In Physics, thermodynamics deals with temperature, heat and their relation to energy, radiation, work, and properties of matter. The energy can be of any forms such as electrical, mechanical, or chemical energy. William Thomson coined the term thermodynamics in 1749. It is derived from two Greek words “thermes” meaning heat, and “dynamikos” meaning powerful.

It is given that,
Vector, a^ =3i^+4j^
Vector, b^ = 2i^-3j^
We have to find the component of vector a along the direction of vector b.
.............(1)
N= -1.6
So, the component of vector a =3 i+4 j along the direction of b =2 i - 3 j is -1.6.
Hence, this is the required solution.

One parsec is _____ light years.
Answer: 3.26
Explanation: Parsec is the unit of length used to measure the large distances to astronomical objects outside the Solar System. It is obtained by the use of trigonometry and parallax.
1 parsec = 3.26 light year
Therefore, one parsec is equal to 3.26 light year.
