<u>Answer</u>:

None of the given options are correct.

<u>Explanation</u>:

As we all know, molecules can be broken down into atoms, and atoms can be broken down into smaller elements, which are electrons, neutrons, and protons.

Atoms forms bonds together to form molecules, and molecules form bonds together to form higher complex elements.

Moreover, molecules consists of different atoms. Considering options, let us first look whether the statements are correct or not, and then will look upon similarity. A is true, as explained above, B is false, as if atoms stopped making bonds, nothing, not even earth would exist. C is definitely false, And even D is false. Considering difference, the correct option is none of the given.

A person travels by car from one city to another with different constant speeds between pairs of cities. She drives for 35.0 min
Lubov Fominskaja [6]

Explanation:

Solution:

Let the time be

t1=35min = 0.58min

t2=10min=0.166min

t3=45min= 0.75min

t4=35min= 0.58min

let the velocities be

v1=100km/h

v2=55km/h

v3=35km/h

a. Determine the average speed for the trip. km/h

first we have to solve for the distance

S=s1+s2+s3

S= v1t1+v2t2+v3t3

S= 100*0.58+55*0.166+35*0.75

S=58+9.13+26.25

S=93.38km

V=S/t1+t2+t3+t4

V=93.38/0.58+0.166+0.75+0.58

V=93.38/2.076

V=44.98km/h

b. the distance is 93.38km

A car travels along straight line for first half time with a speed of 40 km/h and the second half with a speed of 60km/h find th
Vesna [10]

Answer:

Average speed of car will be 48 km/hr  

Explanation:

Let the total distance is 2d

It is given that first half of the distance car travels with a speed of 40 km/hr

So time taken to cover half of the distance t_1=\frac{d}{40}hr

Second half of the distance is covered with a 60 km/hr

So time taken to cover second half of the distance t_2=\frac{d}{60}hr

So total time to cover 2d distance t=\frac{d}{60}+\frac{d}{40}=\frac{5d}{120}

Average speed is the ratio of total distance to total time

So average speed =\frac{2d}{\frac{5d}{120}}=48km/hr

So average speed of car will be 48 km/hr

What is the law of inertia for rotating systems in terms of angular momentum?
saw5 [17]

Answer:

Explanation:

The law of inertia states that if an object is in motion will remain in motion unless an external force is applied to it.

law of inertia for the rotating system in terms of angular momentum states that the angular momentum of a system will remain the same unless an external torque is applied to the system.

External Torque either increases or decreases the angular velocity thus changing angular momentum.
