The twisted ladder shape of the DNA called double helix.

What is DNA?

A polymer made of two polynucleotide chains that coil around one another to form a double helix is called deoxyribonucleic acid. All known organisms and many viruses have genetic information in the polymer that is necessary for their development, operation, growth, and reproduction.

Nucleic acids include DNA and ribonucleic acid (RNA). Nucleic acids are one of the four main categories of macromolecules that are necessary for all known forms of life, along with proteins, lipids, and complex carbohydrates (polysaccharides).

Because the two DNA strands are made up of simpler monomeric units termed nucleotides, they are referred to as polynucleotides.

Each nucleotide is made up of a phosphate group, a deoxyribose sugar, and one of the four nitrogen-containing nucleobases (cytosine [C], guanine [G], adenine [A], or thymine [T]).

Explanation:

When two materials are rubbed against each other, they become charged.

It is called charging by rubbing.

If two objects are rubbed together, especially if the objects are insulators and surrounding air is dry, the objects acquire equal and opposite charges and an attractive force develops between them. The object that loses electrons becomes positively charged. The other that gains electrons becomes negatively charged.

An observer sitting at a bus stop sees the bus drive by at 30 m/s to the east. He also sees a
passenger on the bus walking to the back at 2 m/s. What is the passenger's velocity relative
to the bus?

Answers

Answer:

32 m/s

Explanation:

The speed of a bus is 30 m/s due East wrt the passenger

He also sees a  passenger on the bus walking to the back at 2 m/s.

We need to find the passenger's velocity relative  to the bus. As the observer sees that the bus and the passenger are moving in opposite direction. Let v is the relative velocity. So,

v = 30 m/s + 2 m/s

v = 32 m/s

Hence, the passenger's velocity relative  to the bus is 32 m/s.

A rocket is launched from the launch pad at a speed of 700 km/hr.
How far will the rocket have traveled after 1.5 hour?

Answers

Answer:

Explanation:

Vm = Δs/Δt

700km/h = Δs/1.5h

700 = Δs/1.5

[tex]\frac{700}{1} = \frac{S}{1.5}[/tex]

S = 700 x 1.5

S = 1050 Km

*(S = Δs)

Answer: The rocket will have traveled 1050 Km

Hope this help ☺

After 1.5 hour the rocket will have traveled 1023.54 km.

What is speed?

In everyday use and in kinematics, the speed (commonly referred to as v) of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity.  SI unit of speed is meter/second.

Initial speed of the rocket = 700 km/hr

= 700 (1000/3600) meter/second

= 194.44 meter/second

Acceleration due to gravity is = 9.8 m/s²

Time interval is = 1.5 hour = 1.5 × 60 × 60 second

hence, after 1.5 hour the rocket will have traveled = (194.44) (1.5 × 60 × 60) - 1/2×9.8×(1.5×60×60)² meter

= 1050000 meter - 26460 meter

= 1023540 meter

= 1023.54 km.

So,  the rocket will have traveled 1023.54 km after 1.5 hour .

3. A man heads up a trail going north to see a lake. The trail is 5 miles long and it takes him
2 hours to get there. What was his velocity?

Answers

Answer:

v = 2.5 mi/h

Explanation:

The velocity of an object is defined as the time rate of change of its position. In other words the velocity of an object is just a ration of displacement covered by the object to the time taken by the object, to cover that distance. So, in this case we will use the same formula or equation to calculate the velocity of the man. The formula is as follows:

v = s/t

where,

v = velocity of the man = ?

s = distance of the trail = 5 miles

t = time required to complete the trail = 2 h

Therefore,

v = 5 miles/ 2 h

v = 2.5 mi/h

Answers

Answer:

D

Explanation: Given that a student leaves their history classroom and walks 20 meters north to a drinking fountain. Then the student turns and walks 50 meters south to their art classroom.

The distance is a scalar quantity.

The distance = 50 + 20

distance = 70 metres

Therefore, the magnitude of the total distance traveled by the student is 70 metres. Which is option D

You are going for a drive, but a detour takes you out of the way of your destination. You
drive north for 10 miles, turn right and drive east for 5 miles, turn to the north and drive for 3
miles, drive west for 10 miles, and arrive at your destination.
a) How far from where you started did you end up?
b) If you wanted to travel directly to your destination without following the streets (“as the
crow flies”), what angle would you take? What direction would a compass read?
c) Now try adding the vectors in a different order. For example, start with the 5 miles east,
then 3 miles north, etc., as long as you add all four vectors. Compare the result to the sum
in part a). Draw the vectors in the order you used.

Answers

Answer:

(a). The distance between started point and end point is 13.92 miles.

(b), The direction is 68.9° north - west.

Explanation:

Given that,

You  drive north for 10 miles, turn right and drive east for 5 miles, turn to the north and drive for 3  miles, drive west for 10 miles, and arrive at your destination.

According to diagram

(a).We need to calculate the distance

Using pythagorean theorem

[tex]EO=\sqrt{(ED)^2+(DO)^2}[/tex]

Put the value into the formula

[tex]EO=\sqrt{5^2+(13)^2}[/tex]

[tex]EO=13.92\ miles[/tex]

(b). We need to calculate the direction

Using formula of direction

[tex]\theta=\tan^{-1}(\dfrac{OD}{DE})[/tex]

Put the value into the formula

[tex]\theta=\tan^{-1}(\dfrac{13}{5})[/tex]

[tex]\theta=68.9^{\circ}[/tex]

The direction is 68.9° north - west.

(c). We need to draw a vector diagram

According to vector diagram,

The distance between started point and end point will be same.

Hence, (a). The distance between started point and end point is 13.92 miles.

(b), The direction is 68.9° north - west.

You traveled 150.meters south at a speed of 1.50m/s, and then traveled 600. Meters north at a rate of 2.00 m/s.
1. Wha is the total time of the trip ?
2. What was your average speed ?
3. What was your average velocity ?

Answers

Answer:

1.) 400s

2.) 1.875 m/s

3.) 1.125 m/s

Explanation:

Given that you traveled 150.meters south at a speed of 1.50m/s,

Time = distance/ speed

Substitute speed and distance into the formula

Time = 150/1.5

Time = 100 s

and then traveled 600. Meters north at a rate of 2.00 m/s.

Time = 600 / 2

Time = 300 s

1.) Total time = 100 + 300

Total time = 400 s

2.) The average speed will be total distance travelled over total time.

Total distance travelled = 150 + 600

Total distance travelled = 750 m

Substitute all the parameters into the formula

Average speed = 750/400

Average speed = 1.875 m/s

3.) Average velocity will be displacement over total time

Displacement = 600 - 150

Displacement = 450 m

Average velocity = 450/400

Average velocity = 1.125 m/s
