A cliff jumper jumps off a cliff with an initial horizontal velocity of 10 m/s. The cliff is 10 meters high. How far from the base of the cliff does the diamond fall?

Answers

Answer:

The distance reached is 14.3 m.

Explanation:

To find the distance reached by the diamond first we need to find the flight time:

[tex] t_{v} = \sqrt{\frac{2h}{g}} [/tex]

Where:

h: is the height = 10m

g: si the gravity = 9.81 m/s²

[tex] t_{v} = \sqrt{\frac{2h}{g}} = \sqrt{\frac{2*10 m}{9.81 m/s^{2}}} = 1.43 s [/tex]

Now, we can find the distance reached:

[tex] x = V_{0_{x}}*t_{v} [/tex]

Where:

[tex]V_{0_{x}}[/tex] is the initial horizontal velocity = 10 m/s

[tex] x = V_{0_{x}}*t_{v} = 10 m/s*1.43 s = 14.3 m [/tex]

Therefore, the distance reached is 14.3 m.

A light-rail train going from one station to the next on a straight section of track accelerates from rest at 1.1 m/s^2 for 20s. It then proceeds at constant speed for 1100m before slowing down at 2.2m/s^2 until it stops at the station. A) What is the distance between stations? B) How much time does it take the train to go between the stations?

Answers

Answer:

A) The distance between the stations is 1430m

B) The time it takes the train to go between the stations is 80s

Explanation:

First we will calculate the distance covered for the first 20s.

From one the equations of kinematics for linear motion

[tex]S = ut + \frac{1}{2}at^{2} \\[/tex]

Where [tex]S[/tex] is distance traveled

[tex]u[/tex] is the initial velocity

[tex]t[/tex] is time

and [tex]a[/tex] is acceleration

Since the train starts from rest, [tex]u[/tex] = 0 m/s

Hence,  for the first 20s

[tex]a =[/tex] 1.1 m/s²; [tex]t =[/tex] 20s,  [tex]u[/tex] = 0 m/s

∴ [tex]S = ut + \frac{1}{2}at^{2} \\[/tex] gives

[tex]S = (0)(20) + \frac{1}{2}(1.1)(20)^{2}[/tex]

[tex]S = \frac{1}{2}(1.1)(20)^{2}[/tex]

[tex]S =[/tex] 220m

This is the distance covered in the first 20s.

The train then proceeds at constant speed for 1100m.

Now, we will calculate the speed attained here

From

[tex]v = u +at[/tex]

Where [tex]v[/tex] is the final velocity

Hence,

[tex]v = 0 + 1.1(20)[/tex]

[tex]v = 1.1(20)[/tex]

[tex]v =[/tex] 22 m/s

This is the constant speed attained when it proceeds for 1100m

The train then slows down at a rate of 2.2 m/s² until it stops

We can calculate the distance covered while slowing down from

[tex]v^{2} = u^{2} + 2as[/tex]

The initial velocity, [tex]u[/tex] here will be the final velocity before it started slowing down

∴[tex]u[/tex] = 22 m/s

The final velocity will be 0, since it came to a stop.

∴ [tex]v[/tex] = 0 m/s

[tex]a = -[/tex]2.2 m/s² ( - indicates deceleration)

Hence,

[tex]v^{2} = u^{2} + 2as[/tex] gives

[tex]0^{2} =22^{2} +2(-2.2)s[/tex]

[tex]0=22^{2} - (4.4)s\\4.4s = 484\\s = \frac{484}{4.4} \\s = 110m[/tex]

This is the distance traveled while slowing down.

A) The distance between the stations is

220m + 1100m + 110m

= 1430m

Hence, the distance between the stations is 1430m

B) The time it takes the train to go between the stations

The time spent while accelerating at 1.1 m/s² is 20s

We will calculate the time spent when it proceeds at a constant speed of 22 m/s for 1100m,

From,

[tex]Speed =\frac{Distance}{Time}\\[/tex]

Then,

[tex]Time = \frac{Distance}{Speed}[/tex]

[tex]Time = \frac{1100}{22}[/tex]

Time = 50 s

And then, the time spent while decelerating (that is, while slowing down)

From,

[tex]v = u + at\\0 = 22 +(-2.2)t\\2.2t = 22\\t = \frac{22}{2.2} \\t= 10 s[/tex]

This is the time spent while slowing down until it stops at the station.

Hence, The time it takes the train to go between the stations is

20s + 50s + 10s = 80s

The time it takes the train to go between the stations is 80s

We have know that,

[tex]\green\bigstar\:\rm{\gray{\overbrace{\underbrace{\red{S\:=\:ut\:+\:\dfrac{1}{2}\:at^2\:}}}}}[/tex]

Where,

S = Distance .

u = initial velocity = 0m/s

t = time = 3s

a = acceleration

[Note :- Here, acceleration is ‛acceleration due to gravity’ .]

a = 10m/s^2

=> S = 1/2 × 10 × (3)^2

=> S = 5 × 9

=> S = 45m -----(1)

✒ If the ball takes n’ second to fall the ground, then distance covered in nth second is,

[tex]\green\bigstar\:\rm{\gray{\overbrace{\underbrace{\red{S_n\:=\:u\:+\:\dfrac{g}{2}\:(2n\:-\:1)\:}}}}}[/tex]

=> Sn = 0 + 10/2 (2 × n - 1)

=> Sn = 5 (2n - 1)

=> Sn = 10n - 5 -----(2)

Therefore,

10n - 5 = 45

=> 10n = 45 + 5

=> n = 50/10

=> n = 5

Now put the value of ‛n = 5’ in equation(2), we get

=> Sn = 10 × 5 - 5

=> Sn = 50 - 5

=> Sn = 45m

[tex]\rm{\pink{\therefore}}[/tex] The height of the journey is “ 45m ” .

a man pulls a box with a force of 90.0 N directed along the handle which makes angle of 45 degrees with the ground. find the horizontal and vertical components of this force

Answers

Answer:

The horizontal component of the force, Fₓ = 63.64 N

The vertical component of the force, [tex]F_y[/tex] =  63.64 N

Explanation:

Given;

magnitude of the force, F = 90 N

angle between the handle and the ground, θ = 45°

The horizontal component of the force, Fₓ = Fcosθ

Fₓ = 90 x cos45

Fₓ = 63.64 N

The vertical component of the force, [tex]F_y = Fsin \theta[/tex]

[tex]F_y[/tex] = 90 sin45

[tex]F_y[/tex] = 63.64 N

Therefore, the horizontal  and vertical components of the force is 63.64 N.

1. How do energy and matter recycle in a closed-loop system?

Answers

Answer:

In a closed-loop system, matter is used to generate energy, and the energy generated is used to produce matter, and the cycle goes on without end.

Explanation:

A closed-loop system is one in which materials or energy is recycled without end through a production cycle. This means that a raw material is used to produce a finished product, and the finished product at the end of its use cycle is converted back and used as a raw material to produce more of it again. Energy and matter can also be cycled in the same way in an energy and matter closed-loop system, converting matter to energy, and the energy is put back into the production of more of the matter.

In a closed system loop, the matter has been recycled to provide raw material and form new products. The energy formed by the product has been recycled by being used by the raw materials for the formation of new products.

The closed system loop can be defined as the system in which the products and energy has been recycled continuously to form more products. The energy has been formed in the closed system loop, that can be utilized by the raw materials for the production of energy.

The products formed after reaching the equilibrium of the formation, and dissociation reaches the point, and starts to dissociate to provide the raw material to the system.

Thus, in a closed system loop, the matter has been recycled to provide raw material and form new products. The energy formed by the product has been recycled by being used by the raw materials for the formation of new products.

well thanks for the Information

Explanation:

Torque = Force * Perpendicular distance of the force = 10N * 0.8m = 8Nm.

In diagram A, both torques are acting in a clockwise direction. Hence the net torque is 2N * 1m + 4N * 1m = 6Nm, clockwise.

In diagram B, the torques are acting in opposite directions. For the clockwise one, its torque is 5N * 4m = 20Nm. For the anticlockwise one, its torque is 2N * 10m = 20Nm. Since they are in opposite directions and are equal, they cancel out each other.

Hence net force = 0N and net torque = 0Nm.

Thus, the correct option is C.

What is Diffusion?

Diffusion may be defined as the process of migration of substances or molecules through a semipermeable membrane from an area of higher concentration to an area of lower concentration.

Diffusion does not require energy because it is classified under the passive transport of materials. Diffusion always works towards the concentration gradient.

Energy is typically involved when the movement occurs against the concentration gradient like active transport.

Therefore, the correct option for this question is C.
