Answer:
True
Explanation:
A controlled access high way is a type of high way that access into it is controlled and restricted. It restricts the access to the highway from driveways and only allows traffic to come into through them from interchanges.
A controlled access high way is made up of 4 lanes . A controlled access high way does not allow or permit crossing because vehicles pass through this highways at a very high speed. Traffic is always high or at it's maximum on a controlled access highway.
A controlled access highway lacks the presence of traffic lights.
Answer:
Specific gravity is 0.5 so option (a) is correct option
Explanation:
We have given mass of substance m =10 kg
Volume 
Density of substance is given by 
Specific gravity is given by 
So option (a) is correct option
Answer:
1064.8 kg/m³
Explanation:
Weight of the hydrometer = ρghA where ρ is the density, g is acceleration due to gravity, h is the submerged height and A is the cross sectional area.
W in water = ρwghwA
W in liquid = (ρliq)g hliq A where the cross sectional area is constant
W in water = W in liquid
(ρw)ghwA = (ρliq)g hliq A where ρw is density of water, ρliq is the density of liquid and hw and hliq are the heights of the liquid and that water. g acceleration due to gravity cancel on both sides as well as the constant A
pliq =
× 1000 kg /m³ ( density of water) =(
) × 1000 = 1064.8 kg/m³
Answer:
408 J/kg
662696.7 J/kg
Explanation:
Workdone by compression process in a pump can be isothermally expressed as :

For water at inlet pressure 1. 0 bar;
the specific values for :
saturated vapor 
saturated liquid 
∴ we have
= 1.0 bar = 1. 0 × 10⁵ N/m²
= 50 bar = 50 × 10⁵ N/m²
For saturated water output from condenser work; we have
W = 
W = 
W = 408 J/kg
For saturated vapor output from condenser
Work required :

W = 
W = 662696.7 J/kg
