An Object Of Mass 178 Kg Moves In A Smoothstraight Tunnel Of Length 2640 Km Dug Througha Chord Of A Planet

Answers

Answer 1

Answer: If the mass of the object is 178 kg: k = 9.44*10^-5 N/m

Answer for the mass being 82 kg is not complete, because G was not given.

Explanation:

If the mass of the object is 178 kg:

The mass of object (m) = 178 kg

Length of tunnel (l) = 2640 km

***The minimum displacement (its amplitude) of object from its mean position,

A = 2640/2 = 1320 km = 1.320 * 10^6 m

Mass of planet (M) = 4.48 * 10^24 kg

Its Radius (R) = 8.26 * 10^6 m

Gravitational constant (G) = 6.67259 * 10^-11 Nm^2/kg^2

Now, restoring force for given hormonic motion will be

Vector of F = -((GMm)/R^3) * x

Comparing with, vector of F = -k*x, we get

k = (GMm)/R^3

k = (((6.67259*10^-11)*(4.48*10^24)*178)/(8.26*10^6)^3)

k = ((5320.99017*10^(-11+24))/(563.559976*10^18))

k = 9.44*10^(13-18)

k = 9.44*10^-5 N/m

If the mass of the object is 82 kg:

The mass of object (m) = 82 kg

Length of tunnel (l) = 2430 km

***The minimum displacement (its amplitude) of object from its mean position,

A = 2430/2 = 1215 km = 1.215*10^6 m

Mass of planet (M) = 4.16 * 10^24 kg

Its Radius (R) = 7 * 10^6 m

Gravitational constant (G) not given in the photo

Now, restoring force for given hormonic motion will be

Vector of F = -((GMm)/R^3) * x

Comparing with, vector of F = -k*x, we get

k = (GMm)/R^3

k = ((G*(4.16*10^24)*82)/(7*10^6)^3)

Remember that when multiplying two values with exponents, you add the exponents together!

k = ((3.4112*10^26 * G)/(3.43*10^20))

Insert G to solve!

A ball i thrown horizontally from the roof of a building 55 m tall with a peed of 3. 8 m/. How far from the building will it land?

Answers

If a ball i thrown horizontally from the roof of a building 55 m tall with a speed of 3. 8 m/ so the ball will land 55 m away from the building.

What is speed?

Speed is the rate at which something moves or occurs. It is usually measured in terms of distance over time. Speed can be expressed in many different forms, including miles per hour (mph), kilometers per hour (kph), meters per second (m/s) and even in terms of the speed of light. Speed is a measure of how quickly something moves in a specific direction.

The ball will land 55 m away from the building. This is because the horizontal velocity of the ball is 3.8 m/s, and the time it takes to travel 55 m is 55/3.8 = 14.47 seconds. Since the ball was thrown horizontally, it will travel a horizontal distance equal to the time it took multiplied by the velocity, which is 14.47 * 3.8 = 55 m.

Two 3. 0 g bullets are fired with speeds of 40. 0 m/s and 80. 0 m/s, respectively. What are their kinetic energies? which bullet has more kinetic energy? what is the ratio of their kinetic energies?.

Answers

For the first bullet, kinetic energy is 480 J and for the second bullet, kinetic energy is 1920 J.

What is kinetic energy?

Kinetic energy is the energy possessed by an object or a particle due to its motion. It is the energy of motion and can take many forms, such as the energy associated with an airplane flying through the air, a ball rolling down a hill, a person running, or a car traveling on a highway. In general, kinetic energy is the energy an object has because of its movement.

The kinetic energies of the two bullets can be calculated using the equation KE = (1/2)mv2, where m is the mass of the object and v is the velocity of the object.

For the first bullet, KE = (1/2)(3.0 g)(40.0 m/s)2 = 480 J.

For the second bullet, KE = (1/2)(3.0 g)(80.0 m/s)2 = 1920 J.

The second bullet has more kinetic energy than the first bullet. The ratio of their kinetic energies is 4:1. This means that the second bullet has four times more kinetic energy than the first bullet.

Let’s review the 4 basic kinematic equations of motion for constant acceleration (suggest you commit these to memory):

s = ut + ½at^2 …. (1)

v^2 = u^2 + 2as …. (2)

v = u + at …. (3)

s = (u + v)t/2 …. (4)

where s is distance, u is initial velocity, v is final velocity, a is acceleration and t is time.

If you add 20g of ice at 0 degree celciu to 180g of water at 20 degree celciu, what i the final temperature of the water a all of the ice melt?

Answers

The combined water and melted ice temperature is 31.15°C.

We can use the following formula:

q = m c T is used to calculate the final temperature of the water and melted ice, where:

q = added or lost heat

m = the substance's mass

c = the substance's specific heat capacity

T = temperature change

Finding the heat that the ice has taken away:

(20g) x (2.1 J/g°C) x (0 - (-20))°C = q

q = 8400 J

Identifying the heat gained by water:

(180g) x (4.18 J/g°C) x (T) = q

Taking the heat lost by ice and converting it to the heat gained by water

(180g) x (4.18 J/g°C) x (T) = 8400 J

Trying to find T

T = 8400 J/(180g x 4.18 J/g°C).

ΔT = (8400/756)°C = 11.15°C

We get the final temperature by adding the initial temperature of the water to the temperature change.

T(f) = 20°C + 11.15°C = 31.15°C

As a result, the combined temperature of the water and melted ice is 31.15°C.

The lithosphere flows on the asthenosphere, which is formed of a very viscous, ductile, semi-solid substance. It is around 440km thick and a solid with liquid-like characteristics. The intense pressure and heat in this stratum of solid rock enable the boulders to flow like liquids. The asthenosphere's rocks are less dense than the lithosphere's rocks. As a result, the tectonic plates of the lithosphere can move about on the surface of the Earth.

Answers

Calculate the inverse tangent of the ratio of the displacement components in the y and x directions to determine the direction of the displacement vector. The magnitude of displacement is equal to the distance covered in a given interval of time if the particle moves at a constant or variable velocity in the same direction, because if it changes direction, the magnitude of displacement changes and does not remain equal to the distance covered.

A quantity with magnitude and direction must also follow certain combination rules in order to qualify as a vector. Vector addition, denoted symbolically as A + B = C, is one of these (vectors are conventionally written as boldface letters). Geometrically, the vector sum can be visualized by placing the tail of vector B at the head of vector A and drawing vector C so that it completes the triangle (starting from the tail of A and ending at the head of B). If A, B, and C are vectors, then it must be possible to reverse the operation and achieve the same result (C), B + A = C.

How quickly would water I a river flow past very close contour lines

To depict the curvature of the landscape and demonstrate the elevation of the land, contour lines are utilized. The flow direction of a river can also be shown using contour lines. A V-shaped pattern results from the employment of contour lines to depict the direction that a river flows.

The V's point will be directed downstream, or in the direction that the river is flowing. Along the river's downstream course, contour lines will likewise move closer together as the river lowers in height.

A red cart ma = 2kg and a blue cart ma = 2 kg are ELASTICALLY crahed into each other at the indicated velocitie and bounce. After the colliion which cart will have the SMALLEST peed

Answers

The objects in an elastic collision split apart after impact while maintaining all of their kinetic energy. Kinetic energy, often known as the energy of motion, is discussed in more detail elsewhere.

How do you find the velocity of a bounce?

When the ball is not in contact with the ground, the formula h(t+t0)=v0t12gt2 determines the height at time t following the previous bounce at time t0. where v0 denotes the speed shortly before the bounce.

The mass of the red cart, m1, is equal to m1u1 + m2u2 = m1v1 + m2v2.

The blue cart has a mass of m2.

The red cart's starting speed is u1.

The blue cart's starting speed is u2.

The red cart's ultimate speed is v1.

The blue cart's ultimate speed is v2.

The final speed of each cart is determined by the formula: v1 = [m1u1 + m2u2 - m2v2] / m1

m1u1 + m2u2 - m1v1 = v2 / m2

As m1 = m2, our new equation is: v1 = u1 + u2 - v2.

v₂ = u₁ + u₂ - v₁
