Fun Fact: Peanuts aren’t technically nuts

Q23 In Hindu chronology, the longest time measure is a para. One para equals 311 040 000 000 000 years. Calculate this value in megayears, hours and in seconds. Write your answers in scientific notation. ​

Answers

The conversion in megayears, hours and seconds are :

[tex]1 \: para \: = \: 3.11 \times {10}^{8} \: megayears[/tex]

[tex]1 \: para \: = \: 2.72 \times {10}^{18} \: hours[/tex]

[tex]1 \: para \: = \: 9.81 \times {10}^{21} \: seconds[/tex]

Given that :

1 para = 311040000000000 years

1 mega year = 1 million years :

311040000000000 years expressed in mega years will be :

Let : number of mega years = p

1 mega year = 1,000,000 years

p = 311040000000000 years

Cross multiply :

311040000000000 × 1 = 1,000,000 × p

311040000000000 = 1000000p

p = 311040000000000 / 1000000

p = 311040000 mega years

p = 3.1104 × 10^8 mega years

[tex]1 \: para \: = \: 3.11 \times {10}^{8} \: megayears[/tex]

In hours :

In hours : 8760 hour = 1 year

Let : number of hours = p

1 year = 8760 hours

311040000000000 years = p

Cross multiply :

p = 8760 × 311040000000000

p = 2724710400000000000

p = 2.72 × 10^18 hours

[tex]1 \: para \: = \: 2.72 \times {10}^{18} \: hours[/tex]

In seconds :

31536000 seconds = 1 year

Let : number of hours = p

1 year = 31536000 seconds

311040000000000 years = p

Cross multiply :

p = 31536000 × 311040000000000

p = 9808957440000000000000

what is the relationship between the variables on this graph? The temperature does not have an effect on flow time. As the temperature increases, the flow time increases. As the temperature increases, the flow time decreases.

Answers

Answer: As the temperature increases, the flow time increases.

Explanation: i took the test

The relationship between the variables on this graph is that As the temperature increases, the flow time increases, therefore the correct answer is option B.

What is the kelvin scale of temperature?

It is a scale of temperature used to measure the temperature, the kelvin scale of temperature is also known as the absolute scale of temperature.

The Standard International unit of thermodynamic temperature is the kelvin, often known less frequently as the degree Kelvin. The formal definition of one kelvin is 1/273.16  of the thermodynamic temperature of pure water's triple point.

As shown in the graph as the temperature increase across the X axis the flow time is increasing as well, these two variables are directly proportional to each other.

Thus, The graph shows a link between the variables, showing that when the temperature rises, flow time also rises, hence option B is the proper response.

Blaise is driving a car that is traveling 6.03 m/s and accelerates uniformly at 2.5 m/s² to reach a speed of 12.9 m/s. How long does it take for this acceleration to occur?

Answers

It would take 0.3639 seconds for this acceleration to occur.

Given the following data:

Initial speed, U = 6.03 m/sFinal speed, V = 12.9 m/sAcceleration, a = [tex]2.5 \;m/s^2[/tex]

To find how long it takes for this acceleration to occur, we would use the first equation of motion.

Mathematically, the first equation of motion is given by the formula;

[tex]V = U + at[/tex]

Substituting the values into the equation, we have;

[tex]12.9 = 6.03 + 2.5t\\\\2.5t = 12.9 - 6.03\\\\2.5t = 6.87\\\\t = \frac{2.5}{6.87}[/tex]

Time, t = 0.3639 seconds

Therefore, it would take 0.3639 seconds for this acceleration to occur.

A dog runs 20 m east and then 35 m west in 12 seconds.

What is the dog speed? What is the dogs velocity?

Answers

Answer: Dog's speed = (20 + 35) /12 = 4.583 m/s

Dog's velocity = (20-35)/12 = -1.25 m/s

Explanation: Speed is a scalar quantity so we don't care about direction which means we add the magnitude of both the directions i.e. east and west.

About the velocity, it's a vector quantity. So, we must be very careful with the directions and signs. In cartesian coordinates system, we generally take the right side of origin as the positive x-axis and the left side of origin as the negative x-axis. So, considering the same fact, we consider east as positive side and west as the negative side.

Therefore, when we add 20m + (-35m), we get = -15m and you already have the time period of  12 s.

An apple weighing 1 N falls through a distance of 1m. How much work is done
on the apple by the force of gravity?

Answers

Answer:

W = F × d

W = 1 × 1

W = 1 Joule

step by step explanation

An apple is having a force of 1 N and it travels to a distance of 1 m then the work done on the apple by the force of gravity will be equal to 1 J.

What is Work?

Work is a physics term used to describe the transfer of energy that occurs when an object changes above a distance because of an external force, at least some of which is given in the vector of the dislocation. The element of the strong acting all along the path multiplied by the length of the path can be used to calculate work if the force is constant.

Mathematically, this idea is expressed as W = fd, where W is the effort and f is the force multiplied by d, the distance. Work is completed whenever the pressure is applied at an angle with regard to displacement.

As per the given information in the question,

Force, f = 1 N

Distance, d = 1 m

Then, the work done will be,

W = fd

W = 1 × 1

W = 1 J.

A projectile is launched vertically with an initial velocity of 50 m/s. How long would it take to reach the top of the launch?

Answers

Answer:

Explanation:

Givens

vi = 50 m/s

vf = 0

a = - 9.81

t = ?

Formula

t = (vf - vi)/a

Solution

t = (0 - 50)/-9.81

t = 5.097

Notice that a is made into a minus. It does not mean subtract. It means that the direction of the projectile and gravity must go in opposite directions. You will find that direction is a critically important consideration in physics.

Answer:

It'd take it 5.10 seconds

Explanation:

At the top of the launch, it is maximum height, h

formular derivation :

At maximum height, final velocity, v is zero

From first newtons equation:

[tex]{ \sf{v = u + gt}}[/tex]

v is the final velocity

u is the initial velocity

g is acceleration due to gravity

t is the time taken

but v is zero:

[tex]0 = u + gt \\ gt = u \\ t = \frac{u}{g} [/tex]

since it is vertical motion, u = usin(theta), where angle is 90°

[tex]{ \boxed{t = \frac{u \sin( \theta) }{g} }}[/tex]

t is the time taken to reach the top of the launch:

substitute, taking g to be 9.8 m/s²

[tex]t = \frac{50 \times \sin(90 \degree) }{9.8} = \frac{50}{9.8} \\ \\ { \boxed{ \boxed{time = 5.10 \: seconds}}}[/tex]
