1.

Answer:

C) HCL

Explanation:

here HCL is 100% dissolved in the water because electronegativity difference between H and CL is sufficiently high and it will easily dissociate the charge into two ions.

So here correct answer will be

C). HCL

2.

Answer:

A) 2

Explanation:

Electrical power is defined in terms of current and resistance as

P = i^2R

now we will have current is doubled but resistance is halved

so change will be given as

P' = (2i)^2(\frac{R}{2})

so we have

P' = 2P

so here power is doubled

Which of the following statements about the nuclear strong force is true?
lisabon 2012 [21]

Answer: 2, the nuclear strong force drops to practically nothing at large distances.

Explanation: The protons and neutrons in the nucleus share subatomic particles called pions. This exchange is what keeps the protons and neutrons stuck together in the nucleus. Despite the strong force being the strongest force, it has a very small range. This is because pions have very short lifespans. So, the strong force would have literally no effect at large distances.

Hope that helped! :)

An airplane starts from A and flies to B at a constant speed. After reaching B it returns to A at the same speed. There was no w
Dafna1 [17]

Answer:

When there is wind it takes longer

Explanation:

With no wind, the round trip time is

t_1=\frac{d}{v}+\frac{d}{v}=\frac{2d}{v}

When we have a constant wind speed w

t_2=\frac{d}{v-w} +\frac{d}{v+w} =\frac{2vd}{v^{2} -w^{2}}

comparing the reciprocal times;

\frac{1}{t_2}=\frac{v^{2}-w^{2} }{2vd}=\frac{v}{2d}-\frac{w^{2}}{2vd}   \leq \frac{v}{2d}=\frac{1}{t_1}

This means that t1 is smaller than t2, ergo, it takes longer with wind

At the instant a traffic light turns green, a car starts with a constant acceleration of 1.3 m/s2. At the same instant a truck,
Bas_tet [7]

Answer:

(a) Distance traveled = 75.3846 m

(b) Velocity of car at that instant will be 14 m/sec

Explanation:

We have given acceleration of the car a=1.3m/sec^2

Initial velocity of the cart u = 0 m/sec

(a) According to second equation of motion we know that s=ut+\frac{1}{2}at^2

So distance traveled by car s_c=0\times t+\frac{1}{2}\times 1.3t^2=0.65t^2

As the truck is moving with constant speed

So distance traveled by truck s_t=ut=7t

As the truck overtakes the car

So s_c=s_t

0.65t^2=7t

t=10.769sec

So distance traveled s_c=s_t=7\times 10.769=75.3846m

(b) From second equation of motion we know that v = u+at

So v = 0+1.3×10.769 = 14 m /sec
