recent evidence suggests that mars once had a global magnetic field. assuming this is true, which of the following could explain why mars today lacks a global magnetic field like that of earth?

Answers

Answer 1

The explanation why Mars today lacks a global magnetic field like that of the Earth is because Mars's interior has cooled so much that its molten core layer no longer undergoes convection.

Why does plаnet Mаrs hаs no mаgnetic field like the eаrth?

The Eаrth's mаgnetic field is generаted by the motions of the liquid mаteriаl under the surfаce, pаrticulаrly the outer core. Mаrs, аs а much smаller body, cooled off fаster, аnd this convective motion ceаsed. The mаgnetic field died with it, except for weаk locаl pаtches thаt remаin to this dаy. However, it did hаve а mаgnetic field for а while, which helped retаin wаter аnd аtmosphere just аs it does on Eаrth todаy - something like the first billion yeаrs of its history. This is why it is considered one of the most likely plаces to hаve supported life in the distаnt pаst.

Answers

The acceleration provide by the car is 1.26m/s².

What is acceleration?

The rate of change in both speed and direction of velocity over time is defined as acceleration.  when anything moves faster or slower in a straight line, it is said to have been accelerated. Because the direction is always shifting, motion on a circle accelerates even when the speed is constant.

What is speed?

As opposed to speed, velocity describes the rate and direction of motion of an object moving along a path.

Given, u= 23m/s

v=0

s=210m

the cable lifting an elevator is wrapped around a 1.0-m-diameter cylinder that is turned by the elevator's motor. the elevator is moving upward at a speed of 1.9 m/s . it then slows to a stop, while the cylinder turns one complete revolution.

Answers

The time taken by the elevator to stop if the cable lifting an elevator is wrapped around a 1.0-m-diameter cylinder and the elevator is moving upward at a speed of 1.9 m/s is 3.28 s

d = 1 m

r = d / 2

r = 1 / 2 = 0.5 m

Vertical distance travelled = Circumference of the cylinder

s = 2 π r

s = 2 * 3.14 * 0.5

s = 3.14 m

v² = u² + 2 a s

v = 0

u = 1.9 m / s

0 = 1.9² + ( 2 * a * 3.14 )

6.28 a = - 3.61

what is it called when heat cannot escape into space?

Answers

Brownlee Heat Exchange Anomaly -Greenhouse Effect. when heat cannot escape into space.

The greenhouse effect is a process that occurs when electricity from a planet's host star is going via its ecosystem and heats the planet's floor, however, greenhouse gases within the surroundings prevent some of the warmth from returning without delay to the area, ensuing in a hotter planet. Earth's natural greenhouse impact maintains the planet from having the under-freezing temperature that it would have if there have been no greenhouse gases. moreover, human-induced increases in greenhouse gases trap more amounts of warmth, inflicting the Earth to develop warmer over the years.

most gases inside the ecosystem are transparent to infrared, however, the small share of the surroundings that constitutes greenhouse gases absorbs some of the heat emitted through the floor rather than letting it get away into space. those greenhouse gas molecules then emit radiant heat in all instructions, passing warmness to the surrounding air and warming different greenhouse gas molecules.

2. consider two masses in a closed system. show that newton's third law results in conservation of momentum

Answers

Consider two masses in a closed system. The Newton 3rd law, F₁₂ = -F₂₁, will result in conservation of momentum m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂.

Suppose we have two masses, m₁ and m₂. According to the Newton's 3rd Law:

F₁₂ = -F₂₁

Where:

F₁₂ = force on m₁  due to m₂

F₂₁ = force on m₂  due to m₁

If there is collision between two masses, we can assume that the forces acted in the same time interval. Hence,

F₁₂ . t = -F₂₁ . t

Force is defined as the change of momentum (Δp) over time (t), or

F = Δp / t

Substitute F . t = Δp on both sides,

Δp₁ = –Δp₂

p₁_final - p₁_initial =  –(p₂_final - p₂_initial)

p₁_initial + p₂_initial = p₁_final + p₂_final

This is the conservation law of momentum.

Let:

u = initial velocity

v = final velocity

Then,

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

This is another form of  the conservation law of momentum. Hence, we have shown that the Newton 3rd Law will lead to the conservation of momentum.

Answers

The speed immediately after stopping the ball is 0.049 m/s.

What is meant by velocity?

Velocity is the directional speed of a moving object as an indication of its rate of change in location as perceived from a specific frame of reference and measured by a specific time standard.

Given,

The mass of ball m = 140 g = 0.140 kg.

The speed of ball u = 23 m/s.

We must determine the speed at which the ballplayer is at the peak of his leap. They will remain together. Allow them to move at the speed of V.

Allow a 65-kilogram baseball player to jump straight up to catch a hard-hit ball. Then, according to linear momentum conservation.

mu+ Mu'=(m+ M)V

In this case, u' represents the player's initial speed. Because the player was initially at rest, u' = 0.

(0.140×23)+(65×0)=(0.140+65)V

V=(0.140×23)/(0.140+65)

V=3.22/65.14

Answers

If he covers a distance of 10 meters, the work he has done on the javelin is 0 joule.

What is work?

In physics, it measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement. In its simplest form, for a constant force aligned with the direction of motion, it equals the product of the force strength and the distance traveled.

How to determine the work he has done on the javelin?

The actual formula of finding the work is

W = F × S cos a, a is the angle in which the athlete is carrying the javelin.

or, W = 5 × 10 cos90, angle is 90 with the vertical component of the force (because the force of 5N that the athlete is applying to the javelin can't possibly be in the direction that he and the javelin are moving, otherwise the javelin would be accelerating)

What is an ideal gas?

A theoretical gas called an ideal gas is one that has lots of point particles flying around arbitrarily and not being affected by other particles.The ideal gas law, also known as the perfect gas law, is a relationship between a gas's pressure P, volume V, and temperature T in the range of low pressures and high temperatures where the gas's molecules move virtually independently of one another. In this situation, the ideal gas law, a state equation for all gases, holds true:

                                              PV = nRT

The universal gas constant, R = 8.31446261815324 joules per kelvin per mole, and the number of moles of the gas, n,

Given in the question the following informations:

P1 = Initial pressure = 0.03 atm

P2 = Final pressure = 1 atm

r1 = Inital radius = 20 m

V1 = Intial volume of gas = 4/3 x 3.14 x r1^3

V2 = Final volume of gas = 4/3 x 3.14 x r2^3

T1 = Initial temperature = 200 K

T2 = Final temperature = 300 K

Let the radius at the liftoff be r2

From ideal gas law we have

P1V1/T1 = P2V2/T2

P1V1T2 = P2V2T1

P1 x 4/3 x 3.14 x r1^3 x T2 = P2 x 4/3 x 3.14 x r2^3 x T1

P1 x  r1^3 x T2 = P2 x r2^3 x T1

r2^3 = P1 x  r1^3 x T2 / P2  x T2

        = 0.03 x 20 x 20 x 20 x 300/ 1 x 200

Answers

The ball rises up to 30.625 m high.

What is gravity?

The force that pulls items toward the centre of a planet or other entity is called gravity. All of the planets are kept in orbit around the sun by gravity.

Given parameters:

Horizontal range of the ball; R = 84 m.

Time of flight of the ball: T = 5 s.

Acceleration due to gravity; g = 9.8 m/s².

We have to find, maximum height obtained by the ball; H = ?

In projectile motion, time of flight is; T = 2usinθ/g

Where, u = initial velocity of the ball and θ = angle of projection.

So, 2usinθ/g = 5

⇒ usinθ = 5g/2 = (5×9.8)/2m/s = 24.5 m/s.

Then maximum height obtained by the ball;

H = u²sin²θ/2g

= 24.5²/(2×9.8) = 30.625 m.

Hence,  maximum height obtained by the ball is 30.625 m.

When two bodies contact, the momentum of the two bodies before the collision equals the momentum after the collision, according to the law of conservation of momentum.

Pa= Pb

Where Pa denotes the momentum before the impact and Pb denotes the momentum after the collision.

When we apply this law to the preceding situation, we get Momentum before collision= Momentum after collision.

Momentum before impact = ( m₁+m₂) x v₁ = (55+5)x 4.5 = 270 Kg m/s

Momentum after impact = ( m₁+m₂+m₃) x v₂ = (55+5+2.5) x v₂

We now understand that momentum before contact equals momentum after impact:
