Answer:
The banking angle required is .
Explanation:
Banking of a road is the act of constructing a road along a curved path at a certain angle to avoid skidding-off of vehicles plying it. Centripetal force is required to pull the object moving with a velocity 'v' towards the center of the curve for stability.
The velocity of a car navigating a banked road is given by:
v =(rg ÷ tanθ)
where: r is the radius of the road, g is the gravitational force and θ is the banking angle.
⇒ = rg ÷ tanθ
tanθ =
θ =
= (given that g = 10)
=
= 1.4663
θ =
The banking angle required is .
Answer:
=24.25 ^−1
Explanation:
Let and be initial and final velocity of the body respectively,
be acceleration due to gravity ( 9.8^−2 ), ℎ be the height of the body.
=0 ^ −1
ℎ=30
we know that, ^2−^ 2=2ℎ
^2=2∗9.8∗30
^2=588
=24.25 ^−1
1. Curium
2. xenon
3.the element with valance electron 4 and 2 is Tin and lead
4. Nickel . if when n=3 , the number of electrons is 18 , then the total number of electrons will be 28 ; because there will be 2 electrons in n=1 and 8 electrons when n=2 using the equation .Thus atomic number will be 28. The element with atomic number 28 is Nickel
5. Deuterium .Its an isotope of hydrogen. it has only one neutron
It deals with skin diseases
shhhh hahahaha ahhhhhhhh ahhhh
