m/s

A particle with initial velocity v₀ = (-2i - 4j) m/s undergoes a constant acceleration, a = 3 m/s² at 37° with positive direction of x - axis.

We have to find the velocity of particle at t = 5 sec.

initial velocity, v₀ = (-2i - 4j) m/s

constant acceleration, a = 3(cos37° i + sin37° j)

= 3(0.8 i + 0.6 j)

= 2.4 i + 1.8 j

let final velocity of the particle is v

time taken, t = 5 sec

now using formula,

[tex]\vec v=\vec u+\vec at[/tex]

here,

[tex]\vec u=v_0=(-2\hat i-4\hat j)\\\vec a=(2.4\hat i+1.8\hat j)[/tex]

[tex]\implies\vec v=(-2\hat i-4\hat j)+(2.4\hat i+1.8\hat j)\times5\\\\=10\hat i+5\hat j[/tex]

Answer:

Education provides us knowledge. It trains our mind and sharpens our skills and abilities. Education refines our tastes and temperaments and builds our thought process. Vocational courses help young boys to earn and learn together. They provide means of earning livelihood and open the route to employment. Professional courses, as is evident from the name itself, equip us for adopting various professions. Some of these highly skilled professionals seek placements or jobs in esteemed companies and business concerns. Thus education is important for our survival. Decent living is impossible

without good income or high salary. Education improves the quality of our life and frees us of superstition, foolish, meaningless mind-blocks and rituals. If women are educated the whole family benefits qs the food is hygienically prepared, children are healthy, well-mannered and disciplined. Education gives us power over our environment. We can control the situation and shape our destiny. Education spreads awareness among people and gives them freedom from social ills. It makes people independent by providing them means to learn their living. They become responsible citizens and realise their rights and duties. In short, education gives one power.

Answer:

increase in pressure

δP = P(2m below) - P(atm)

= ρhg + Patm - Patm

= ρhg

= 1000×2×9.8

= 19600 N\m² or Pa

Answer:

19600 Pa

Explanation:

- To Calculate increase in pressure at a depth or in other words at the bottom of a liquid, The Formulae used is: P = hdg OR P = hpg.

- In the formulae :

P = stands for Pressure.

h = Stands for Depth.

d Or p (rho) = Stands for density.

And lastly g = stands for gravitational field strength. (which is equal to 9.8 or 10 rounded up.)

- For calculation:-

P = hdg

P = 2 x 9.8 x 1000

P = 19600 Pa

-Why Pascals? Because when Depth (h) is in m and density (p or d) is in kg/m³ Then pressure will be in Pascals (Pa).

Note: I know I made the answer seem long and complicated But To me when I see answers like this, It helps me understand better and so I hope you do too.
