Question

A car, being driven at 60 km/h, is to be stopped by applying brakes within a distance of 5m. If the car and passenger weight 1800 kg, then find average force which must be applied by the brakes.​

Answer 1

Answer:

=40m,v=0,u=40× 18 5

= 9 100 m/s u

2 =2as ( 9 100 )

2 =2×a×40

9 100 × 9

100 =2×40×a

a=81×8 1000

Force=ma =2000× 81×8 1000

Force =3.086KN

Explanation:

Answer 2

Isoalleles refer to the type of alleles at the same loci whose phenotype is indistinguishable , but only can be distinguished with special analysis. Psuedoalleles are functionally alleles but structurally are not.
