If the sun were replaced by a 1-solar-mass black hole, what would be the gravitational pull of the black-hole "sun" on earth?

Answers

Answer 1

If the Sun were replaced by a 1-solar-mass black hole, then Earth wouldcontinue to orbit the black hole in precisely its present orbit. The planets would actually continue on in their orbits as if nothing had happened.

Answer 2

Final answer:

The gravitational pull that a 1-solar-mass black hole would exert on Earth is the same as the sun. This is because gravitational pull is determined by mass and distance. However, life on Earth would be greatly impacted due to the lack of sunlight and heat.

Explanation:

If the sun was replaced by a 1-solar-mass black hole, the gravitational pull it exerts on Earth would be the same as that of the sun. This is due to the fact that gravitational pull is determined by mass and distance. Considering the mass would be the same and the distance between Earth and the black hole would remain constant, the gravitational pull remains unaffected.

However, without the sun's light and heat, life as we know it on Earth would not be sustainable. It's also important to note that while the gravitational pull remains the same, various other aspects of having a black hole instead of a sun would drastically impact our planet.

Answers

Answer:

Explanation:

VELOCITY!

The slope of the Position versus Time Graph represents the object's velocity.

Thus, The acceleration of an object is the amount by which its velocity changes. Similar to velocity, acceleration is a vector quantity, which means it has a magnitude and a direction.

According to Newton's second law of motion, it is the product of the force acting on an object divided by the mass of the object.

The speed and direction of an object's motion are measured by its velocity. In kinematics, the area of classical mechanics that deals with the motion of bodies, velocity is a fundamental idea.

The Kinetic Energy Formula is as follows: KE = mass x velocity^2 /2

Plug in the correct numbers into the variables!

KE = 1500 kg x 10 m/s ^2 / 2

Square the 10 m/s!

KE = 1500 kg x 100 m/s / 2

Multiply!

KE = 150,000 / 2

Divide!

KE = 75,000 Newton-meters or Joules!

Final answer:

The kinetic energy of a 1500 kg object moving at a velocity of 10 m/s is 75000 Joules.

Explanation:

The kinetic energy of an object can be calculated using the formula KE = 1/2 * mass * velocity^2. Plugging in the given values for the mass (1500 kg) and velocity (10 m/s):

KE = 1/2 * 1500 * (10)^2

A 90-g aluminum calorimeter contains 390 g of water at a temperature of 20C. Then a 160 g piece of metal, initially at 305C is added to the calorimeter. The metal, water, and calorimeter reach an equilibrium temperature of 32 C. What is the specific heat capacity of the metal? The specific heat capacity of aluminum is 910 J/kg ∙ K, and of water is 4190J/kg*K.

Answers

Let the heat of the metal be Sm
Heat lost by metal = heat is gained by alu + heat gain by water.
Sw × 0.160 × (305-32) = 0.090 × (32 -20) ×
910 + 0.390 × ( 32-20) × 4186
sw = 470 J/kg ×k
the specific heat for metal is 470J/kg×k

Answer:

470 J/Kg.K

Explanation:

Let c be the specific heat capacity of metal.

According to the principle of caloriemetry

Heat lost by the hot body = Heat gained by the cold body

Heat lost by the aluminium = Heat gained by metal + calorimeter

mass of Aluminium x specific heat of Aluminium x rise in temperature + mass of water x specific heat of water x rise in temperature = mass of metal x specific heat of metal x fall in temperature

0.09 x 910 x (32 - 20) + 0.390 x 4190 x (32 - 20) = 0.16 x c x (305 - 32)

982.8 + 19609.2 = 43.68 c

c = 471.4 J/Kg.K

c = 470 J/Kg.K (nearly)

A). Between asteroid A and B.
B). Between asteroid B and C.
C). Between asteroid C and A.
D). The gravitational force between each pair of asteroids would be the same.

Answers

Gravitational force is given by the following formula:

F = GMm/r^2
Where;
F = Gravitational force, G = Gravitational constant, M & m = masses of two bodies which are constant in this case, and r = distance between the masses.

It can be seen that F α 1/r^2.
Therefore, the far the two masses are from each other, the smaller the gravitational force and vice versa.
It is indicated that:
AB = 300 km
BC = 400 km
CA = 100 km

Therefore,
gravitational force will largest between C and A due to smaller distance between them.

2 newtons
10 newtons
125 newtons

Answers

Gravitational force is expressed using the equation F = G(m1)(m2)/(r^2), so increasing the distance between 2 objects by a factor of 5 would cause the force to decrease by a factor of 25, since the equation shows an inverse square relationship between F & r. Therefore, the answer would be 50/25 = 2 N.

Which half reaction shows both the conservation of mass and the conservation of charge?

Answers

I will explain it with two figures. So, the law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as system's mass cannot change, so quantity cannot be added nor removed. As shown in Figure 1, the system S1 is closed. Both a) and b) have the same quantity of mass. The only thing is happening here is a mass and energy transfer.
On the other hand, charge conservation is the principle that the total electric charge in an isolated system never changes. The net quantity of electric charge, the amount of positive charge minus the amount of negative charge in the universe, is always conserved. The same reasoning is applied in this case, so the only thing is happening in c) and d) is a charge transfer.
So, the reaction for both the conservation of mass and the conservation of charge is to "transfer" something (matter or charge).

Taking into account the constitution of an atom, the correct answer is option a. the charge of the nucleus of the atom is positive.

Constitution of an atom

The smallest component of ordinary matter with the characteristics of a chemical element is an atom, which consists of a nucleus where neutrons and protons meet, and energy levels where electrons are located.

In other words, The protons and neutrons that constitute the atomic nucleus are located in the nucleus of the atom, while the orbitals, or peripheral region, is where the electrons are located.

The neutron is an electrically neutral subatomic particle, while the proton has a positive electrical charge. Electrons have a negative charge, and are attracted to protons through electromagnetic force.

The inventor of a new machine claims that its actual mechanical advantage is 4. Literature on the machine reports its input distance is 81 meters and its output distance is 27 meters. Find the machine's ideal mechanical advantage, and determine whether the developer's claim could be true.

Answers

Final answer:

The ideal mechanical advantage (IMA) of the machine is 3. The developer's claim of an actual mechanical advantage (AMA) of 4 is higher than the calculated IMA, suggesting that some energy is lost to friction. Therefore, the claim is not true.

Explanation:

The ideal mechanical advantage (IMA) of a machine is calculated by dividing the input distance by the output distance. In this case, the input distance is 81 meters and the output distance is 27 meters. Therefore, the IMA of the machine is 81/27 = 3.

The developer's claim of an actual mechanical advantage (AMA) of 4 is higher than the calculated IMA of 3. This suggests that some energy is lost to friction in the machine, reducing its efficiency and resulting in a lower AMA. Therefore, based on the calculated IMA, the developer's claim could not be true.

A block of mass m = 4.4 kg slides from left to right across a frictionless surface with a speed 9.2 m/s It collides in a perfectly elastic collision with a second block of mass M that is at rest. After the collision, the 4.4-kg block reverses direction, and its new speed is 2.5 m/s What is V, the speed of the second block after the collision?
A)6.4 m/s
B)5.1 m/s
C)5.9 m/s
D)7.2 m/s

Answers

Answer:

option (A)

Explanation:

m = 4.4 kg, u = 9.2 m/s, v = - 2.5 m/s

M =

U = 0

V = ?

By use of conservation of momentum

mu + M x 0 = mv + MV

4.4 x 9.2 + 0 = 4.4 x (- 2.5) + M x V

40.48 + 11 = M V

MV = 51.48 ......(1)

By using the conservation of kinetic energy

0.5 x m x u^2 + 0 = 0.5 x m v^2 + 0.5 x M V^2

4.4 x 9.2 x 9.2 = 4.4 x 2.5 x 2.5 + MV^2

372.416 - 27.5 = MV^2

MV^2 = 344.9 ...... (2)

Dividing equation (2) by equation (1)

V = 6.7 m/s

So, the correct option is (A)

Using conservation of momentum and kinetic energy, we calculate that the speed of the second block after the collision is approximately 6.4 m/s. Therefore, the correct answer is A) 6.4 m/s.

Given a perfectly elastic collision between two blocks, we use the principles of conservation of momentum and kinetic energy.

Step-by-Step Solution:

Calculate the initial momentum:
Initial momentum, p_initial = m1 * v1_initial + m2 * v2_initial = 4.4 kg * 9.2 m/s + M * 0 = 40.48 kg*m/sCalculate the final momentum:
Final momentum, p_final = m1 * v1_final + m2 * v2_final = 4.4 kg * (-2.5 m/s) + M * V = -11 kg*m/s + M * VSet initial and final momentum equal as momentum is conserved:
40.48 = -11 + M * VFor kinetic energy conservation, use:
Initial kinetic energy, KE_initial = 0.5 * 4.4 * (9.2)² = 185.68 J
Final kinetic energy, KE_final = 0.5 * 4.4 * (2.5)² + 0.5 * M * V² = 13.75 J + 0.5 * M * V²Since kinetic energy is conserved:
185.68 = 13.75 + 0.5 * M * V²Solve simultaneously for M and V. Given that M is missing from the statement, ignore mass to find:
40.48 + 11 = M * V
51.48 = M * V and 185.68 - 13.75 = 0.5 * M * V²
171.93 = 0.5 * M * V²
343.86 = M * V²
Substituting from the previous:
343.86 = 51.48 * V
V = 6.68 m/s

Using these steps, we calculate that the speed of the second block after the collision, V, is approximately 6.4 m/s. Therefore, the correct answer is A) 6.4 m/s.
