The main reason to suspect that Enceladus has a subsurface ocean of water is the presence of geysers erupting from its southern polar region.

The Cassini spacecraft detected plumes of water vapor, ice particles, and organic molecules coming from the moon's surface, indicating the presence of a liquid water ocean beneath the icy crust. This discovery has led to the hypothesis that Enceladus could potentially harbor life in its subsurface ocean.

Enceladus, one of Saturn's moons, has a subsurface ocean of water is due to the presence of cryovolcanism, observed geysers, and the detection of water vapor and ice particles in its plumes. These factors provide strong evidence for the existence of liquid water beneath the icy surface of Enceladus.

Answer:

B is the correct answer to the order

The change in gravitational potential energy of the spacecraft as it moves from point B to point A is 8.3x10^9 J.

The change in gravitational potential energy of the spacecraft as it moves from point B to point A can be calculated using the formula:

                    \(ΔPE = -GMm(1/rA - 1/rB)\) , where

ΔPE is the change in gravitational potential energy,

G is the gravitational constant,

M is the mass of the planet,

m is the mass of the spacecraft,

rA is the distance from the planet's center at point A, and

rB is the distance from the planet's center at point B.

Using the given values, we have:

\(ΔPE = -(6.67x10^-11 Nm^2/kg^2)(1.50x10^24 kg)(650 kg)(1/5.00x10^7 m - 1/0)\)\(ΔPE = -(6.67x10^-11 Nm^2/kg^2)(1.50x10^24 kg)(650 kg)(1/5.00x10^7 m - 1/0)\)

Simplifying the expression, we get:

\(ΔPE = -8.3x10^9 J\)

Therefore, the change in gravitational potential energy of the spacecraft as it moves from point B to point A is \(8.3x10^9\)J, which is a negative value because the spacecraft is moving closer to the planet and its gravitational potential energy is decreasing.

A centrifuge is a device in which a small container of material is rotated at a high speed on a circular path: The sample is making approximately 278 revolutions per minute.

To determine the number of revolutions per minute the sample is making, we need to relate the centripetal acceleration, radius, and angular velocity.

Centripetal acceleration (a_c) is related to the radius (r) and angular velocity (ω) by the formula: a_c = rω².

Given that the centripetal acceleration of the sample is 7.98 x 10³ times the acceleration due to gravity (g), we can write: a_c = 7.98 x 10³g.

We know that the acceleration due to gravity is approximately 9.8 m/s².

Substituting the values, we have: 7.98 x 10³g = rω².

Rearranging the equation to solve for ω, we get: ω = sqrt((7.98 x 10³g) / r).

The radius is given as 6.07 cm, which is 0.0607 m.

Substituting the values, we find: ω = sqrt((7.98 x 10³ * 9.8) / 0.0607).

Calculating this expression, we find ω ≈ 511.26 rad/s.

To convert this angular velocity to revolutions per minute, we can use the conversion factor: 1 revolution = 2π radians.

Thus, the number of revolutions per minute is approximately ω / (2π) * 60, which is approximately 278 revolutions per minute.

The temperature at which water freezes and the temperature at which ice melts are the same, which is 0 degrees Celsius or 32 degrees Fahrenheit at standard pressure. The correct answer is C.

This is because when water freezes, it changes from a liquid state to a solid state, and when ice melts, it changes from a solid state to a liquid state. Both of these processes involve a change in the temperature of the substance, but they occur at the same temperature point.

Additionally, the boiling point of water can vary depending on the pressure it is under. However, in a pressure cooker, the pressure is increased, which raises the boiling point of water. So, the temperature at which water boils in a pressure cooker is higher than the normal boiling point, but it is still not the same as the temperature at which water freezes or ice melts.

Answer:

the period of the 16 m pendulum is twice the period of the 4 m pendulum

Explanation:

Recall that the period (T) of a pendulum of length (L)  is defined as:

\(T=2\,\pi\,\sqrt{ \frac{L}{g} }\)

where "g" is the local acceleration of gravity.

SInce both pendulums are at the same place, "g" is the same for both, and when we compare the two periods, we get:

\(T_1=2\,\pi\,\sqrt{\frac{4}{g} } \\T_2=2\,\pi\,\sqrt{\frac{16}{g} } \\ \\\frac{T_2}{T_1} =\sqrt{\frac{16}{4} } =2\)

therefore the period of the 16 m pendulum is twice the period of the 4 m pendulum.

1. 0.5g*t^2 = 2010 m.

4.9t^2 = 2010.

t = 20.3 s. = Fall time.

D = Xo*t. = 193m/s * 20.3s = 3909 m.

2. V=sqrt(Xo^2+Yo^2)=sqrt(193^2+58^2) = 202 m/s.

3. Vo*t + 0.5g*t^2 = 2010 m.

58*t + 4.9*t^2 = 2010.

4.9t^2 + 58t - 2010 = 0.

Use Quadratic Formula.

t = 15.2 s. = Fall time.

D = 193m/s * 15.2s = 2934 m.

Given :

Initial velocity, u = 12.5 m/s.

Height of camera, h = 64.3 m.

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

To Find :

How long does it take the camera to reach the ground.

Solution :

By equation of motion :

\(h = ut+\dfrac{gt^2}{2}\)

Putting all given values, we get :

\(12.5t+\dfrac{9.8t^2}{2}=64.3\\\\4.9t^2+12.5t=64.3\)

t = 2.56  and t = −5.116.

Since, time cannot be negative.

t = 2.56 s.

Therefore, time taken is 2.56 s.

Hence, this is the required solution.

Answer:

Temperature or thermal energy.

Explanation:

Conduction involves the transfer of electric charge or thermal energy due to the movement of particles. When the conduction relates to electric charge, it is known as electrical conduction while when it relates to thermal energy, it is known as heat conduction.

In the process of heat conduction, thermal energy is usually transferred from fast moving particles to slow moving particles during the collision of these particles. Also, thermal energy is typically transferred between objects that has different degrees of temperature and materials (particles) that are directly in contact with each other but differ in their ability to accept or give up electrons.

Hence, the temperature or thermal energy of matter depends on how much the particles are moving, which depends on the amount of kinetic energy the particles possess.​

The half life of carbon -14 is 5700 years. Then the decay constant is 0.0002 yrs⁻¹. The time period it takes to reach a count of 150 from 200 will be 2937 years.

Half life of a radioactive isotope is the time required to decrease half of its initial amount.  The radioactive decay is a first order reaction. Hence the time of decay is written  as:

t = 1/k ln W0/Wt

where Wt and W0 be the final and initial amounts respectively.

Decay constant k = 0.693/t1/2

k = 0.693/5700 yrs = 0.0002 yrs⁻¹.

W0 = 200

Wt = 150

Then,

t = 1/ 0.0002 yrs⁻¹.ln (200/150) = 2397 years.

Therefore, after 2397 years later the second count was done for the sample.
