Velocity (m/s)

alekssr [168]

Explanation:

⠀

(a) The segment A shows acceleration as velocity increases with the increase in time.

⠀

(b) The segment C shows the object is slowing down as the time increases in segment C, the velocity decreases and afterwards it comes to rest.

⠀

(c) The velocity is segment B is 40m/s. And in the diagram there is no change in velocity.

⠀

(d) The acceleration of segment B is zero. As there in no change in curve and it is moving with uniform velocity.

A light ray is incident on a plane surface separating two transparent media of refractive indices of 1.65 and 1.35. If the incid

Vesna [10]

Explanation:

Given

Refractive Index $(n_1)=1.65$

$n_2=1.35$

angle of incident $=35 ^{\circ}$

Light originates in the medium of higher refractive index

Let $\theta _1$ and $\theta _2$ be the incident and refraction angles respectively thus according to snell's law

$n_1sin\theta _1=n_2sin\theta _2$

$1.65\times sin35=1.35\times sin\theta _2$

$sin\theta _2=0.701$

$\theta _2=44.507^{\circ}$

(b)Ray originates from lighter medium

$1.35\times sin35=1.65\times sin\theta _2'$

$sin\theta _2'=0.469$

$\theta _2'=27.96\approx 28^{\circ}$

A motorboat approaches you head-on and sounds one short blast. how do you signal that you agree to let it pass on your port (lef

nadya68 [22]

The blast made by the vessel's driver is telling you that he intends to pass by your left side. If you agree with his intention, you will respond by sounding one short blast in return. If you are not in agreement with this move or you do not really understand the intention of the driver, you will give the danger signal which is five short rapid blasts.
