Snow on the ground prevents polar climate systems from gaining heat by what mechanism?

Question 7 options:

Heating by greenhouse gases


Snow reflecting solar radiation


Heat spread from the equator


Release of heat from Earth's core

Answers

The characteristics of the thermal heating mechanisms allow to find the correct answer for how snow prevents soil heating is:

         b) Snow reflecting solar radiation.

The heating of the system occurs by absorption of energy by three basic mechanisms:

Conduction. It occurs when the bodies are in constant and energy is transferred by the oscillations of the elements of the body, but there is no physical displacement of parts of it. Convection. This mechanism occurs mainly with liquid and gases, it is due to the displacement of masses of the element due to its greater energy. Radiation. In these mechanisms there is no physical contact and the energy is transferred by the emission of electromagnetic waves.

In this case, the snow receives electromagnetism waves from the sun, a large part of these waves are reflected by the snow, therefore they do not reach the ground and cannot be absorbed, thus decreasing its heating.

Let's analyze the claims:

a) False. Greenhouse gases do not interfere with snow on the ground.

b) True. This mechanism reduces radiation heating.

c) False. The heat that comes from the equator warms the air.

d) False. Heating by the Earth's core occurs everywhere and comes from the center of the earth, so it does not interact with snow.

In conclusion, with the characteristics of the thermal heating mechanisms, we can find the correct answer for how snow prevents soil heating is:

         b)  Snow reflecting solar radiation

Two billiard balls having the same mass and speed roll directly toward each other. What is their combined momentum after they meet

Answers

Their combined momentum after they meet is 0.

What is law of conservation of momentum?

According to the law of conservation of momentum, absent an external force, the combined momentum of two or more bodies operating upon one another in an isolated system remains constant. As a result, momentum cannot be gained or lost.

Let the mass of each billiard balls = m.

If the initial velocity of first ball is u; according to the question, the initial velocity of the second ball be -u.

Hence, initial momentum of the first ball is: P₁ = mu

initial momentum of the second ball is: P₂ = -mu

Hence, total initial momentum of the two balls = P₁ + P₂ = mu + ( -mu) = 0.

So, according to law of conservation of momentum:

draw the following vector quantity Using the coordinate system.
a. 190 newton east
b. 120km/hr, 250 north of east
c. 60 meters southwest​

Answers

The given vectors quantities can be described by their properties of both

magnitude and direction.

a. The drawing of the vector extending from point (0, 0) to (190, 0) on the coordinate plane is attached.b. The velocity vector extending from  (0, 0) to (108.76, 50.714) on the coordinate plane is attached.c. The displacement vector extending from (0, 0) to (30·√2, 30·√2) is attached.

Reasons:

a. The magnitude of the vector = 190 N

The direction in which the vector acts = East

Therefore, in vector form, we have;

[tex]\vec{F}[/tex] = 190 × cos(0)·i + 190 × sin(0)·j = 190·i

The vector can be represented by an horizontal line, 190 units long

Coordinate points on the vector = (0, 0) and (190, 0)

The drawing of the vector with the above points using MS Excel is attached.

b. Magnitude of the velocity vector = 120 km/hr. 25° North of east

Solution;

The vector form of the velocity is; [tex]\vec{v}[/tex] = 120 × cos(25)·i + 120×sin(25)·j, which gives;

[tex]\vec{v}[/tex] = 120 × cos(25)·i + 120×sin(25)·j ≈ 108.76·i + 50.714·j

[tex]\vec{v}[/tex] ≈ 108.76·i + 50.714·j

Therefore, points that define the vector are; (0, 0) and (108.76, 50.714)

The drawing of the vector is attached

c. The magnitude of the vector = 60 m

The direction of the vector is southwest = West 45° south

The vector form of the displacement is [tex]\vec{d}[/tex] = 60 × cos(45°)·i + 60 × sin(45°)·j

Which gives;

[tex]\vec{d}[/tex] = 30·√2·i + 30·√2·j

Points on the vector are therefore; (0, 0), and (30·√2, 30·√2)

Jeff Gordon leads his race and must drive into a curve at top speed to win it all. The radius of the curve is 1000 m and the coefficient of static friction between his tires and the dry pavement is 0.50.

Answers

Answer:

Apparently the curve is not banked.

The maximum frictional force is -

Ff = m g * .5

Fc = m v^2 / R     where Fc is the centripetal force that must be present in

                            order for the car not to slip.

.5 g = v^2 / R      equating forces

v^2 = .5 R g = .5 ^ 1000 * 9.80

v = (500 * 9.80)^1/2 = 70 m/s

(about 230 ft/sec = 230/88 * 60 = 157 mph

Two horizontal curves on a bobsled run are banked at the same angle, but one has twice the radius of the other. The safe speed (no friction needed to stay on the run) for the smaller radius curve is v. What is the safe speed on the larger radius curve?
A) v/2
B) v /√ 2
C) 2v
D) v√2



I shall answer it here so this can help other students out
First, FN = mg/cos
On a banked curve, FNx is the only acceleration force
FNx = mv^2/r
FNx = FNsin
mg/cos * sin = mv^2/r
cancel out the mass (m) and sin*1/cos is tan
gtan = v^2/r
rgtan = v^2
√(rgtan) = v (this is the velocity for the smaller radius.)
call larger radius velocity X

for larger radius, it becomes 2r, so √(2rgtan) = X

understand you can do √xy = √x * √y

√(rgtan) * √2 = X (√(rgtan) = v)
v * √2 = X (where X is velocity with larger radius)

Answers

Newton's second law and universal gravitation law allow to find the results for questions about the motion of satellites in orbit are:

1) The correct answer is D:  v = 8.17 10³ m/s

2) The correct answer is B

    The velocity of Satellite A is greater than the velocity of Satellite B.

3) The correct answer is B

   Toward the center of Earth

4) The correct answer is B

   The gravitational force increases and the velocity increases.

Newton's second law establishes a relationship between force, mass, and the acceleration of bodies.

           F = m a

In the case of the satellite the force is given by the law of universal gravitation.

           [tex]F = - G \frac{Mm}{r^2 }[/tex]

Where G is the constant of universal gravitation. M and m the mass of each object and r the distance between them.

In this case the satellite is in a circular orbit, therefore the acceleration is centripetal.

          [tex]a = \frac{v^2}{r}[/tex]  

We substitute.

      [tex]G \frac{Mm}{r^2} = m \frac{v^2}{r}[/tex]  

       [tex]\frac{GM}{r} = v^2[/tex]  

Let's analyze the answers to find the correct one.

1) They indicate the height of the space station r = 4.08 10⁵ m and ask the speed.

          [tex]v= \sqrt{ \frac{6.67 \ 10 ^{-11} 5.9 \ 10^{24}}{4.08 \ 10^6 } }[/tex]  

          v = 9.82 10³ m / s

The correct answer is D.

2) Satellite A has an orbit of hₐ = 500 km and satellite b an orbit of

    h_b = 800 km

The distance from the center of the earth to each satellite is:

          rₐ = R + hₐ

          r_b = R + h_b

          rₐ = 6.37 106 + 500 10³ = 6.87 10⁶ m

          r_b = 6.37 10⁶ + 800 10³ = 7.17 10⁶ m

Let's find the ratio of the speeds

         [tex]\frac{v_a}{v_b} = \sqrt{ \frac{r_b}{r_a} } \\\frac{v_a}{v_b} = \sqrt{ \frac{7.17}{6.87} }[/tex]

        [tex]\frac{v_a}{v_b}[/tex]  = 1,022

we see that the speed of satellite a is slightly greater than the speed of satellite b.

Let's analyze the claims.

A) False. The speed does not depend on the mass of the satellites.

B) True. The velocity of a is slightly greater than the velocity of b.

C) False. The speed of a is greater.

D) False. The speed of a is greater.

3) As the orbit is circular, the force must be radial, that is, it points towards the center of the earth.

Let's analyze the claims.

A) False. The speed modulus does not change, therefore there is no acceleration in the direction of the satellite.

B) True. Aim for the center of the Earth, change the direction of the velocity.

C) False. Aim for the scepter of the earth.

D) false. The modulus of velocity is constant and the direction changes towards the center of the earth, therefore the force must go towards the center of the earth.

4) The force in the law of universal gravitation increased as the distance decreased.

When a satellite approaches the earth its speed must increase since the speed is proportional in inverse of the square root of the distance.

Let's examine the claims.

A) False. The attraction force increases.

B) True. You agree with the explanation.

C) False. The gravitational force increases.

D) False. Speed ​​increases.

In conclusion, using Newton's second law and the universal law of gravitation we can find the results for the questions about the movement of satellites in orbit are:

    1) The correct answer is D:  v = 8.17 10³ m/s  

    2) The correct answer is B

    The velocity of Satellite A is greater than the velocity of Satellite B.

    3) The correct answer is B

    Toward the center of Earth

    4) The correct answer is B

   The gravitational force increases and the velocity increases.

This question involves the concepts of the law of conservation of momentum.

The magnitude of the final momentum of the eight ball is "0.22 N.s".

According to the law of conservation of momentum:

[tex]P_{i1}+P_{i2}=P_{f1}+P_{f2}[/tex]

where,

[tex]P_{i1}[/tex] = initial momentum of the cue ball = 0.23 N.s

[tex]P_{i2}[/tex] = initial momentum of the eight ball = 0 N.s (since ball is initially at rest)

[tex]P_{f1}[/tex] = final momentum of the cue ball = 0.01 N.s

[tex]P_{f2}[/tex] = final momentum of the eight ball = ?

Therefore,
