Answer:

Gravity at a distance of 4R will be reduced to 1/16 th.

Explanation:

Given:

At the surface of the moon, the acceleration due to the gravity of the moon is x.

We have to find the gravity a t a distance of 4 times from the center of the moon.

Let the radius of the moon be "R".

And

The value of acceleration due to gravity is g_m .

Formula:

⇒ g_m=\frac{GM}{R^2}   ...where M is the mass of the moon.

Now

Gravity of the moon at the its surface:

⇒ g_m=\frac{GM}{R^2}    ...equation (i)

Gravity of the moon at a distance of  4R:

⇒ g_m_1=\frac{GM}{(4R)^2}

⇒ g_m_1=\frac{GM}{16R^2}   ...equation (ii)

Dividing equation (i) with (ii) to find the relationship between the two.

⇒ \frac{g_m_1}{g_m} =\frac{GM}{16R^2}\times \frac{R^2}{GM}

⇒ \frac{g_m_1}{g_m} =\frac{1}{16}

⇒ g_m_1 =g_m(\frac{1}{16})

⇒ g_m_1 =x(\frac{1}{16})    ...as gm=x at the surface.

So,

We can say that the gravity at a distance of 4R will be reduced to 1/16 th.

Write the equation that links current, potential difference, and resistance
mrs_skeptik [129]

You can write the equation in 3 different ways, depending on which quantity you want to be the dependent variable.  Any one of the three forms can be derived from either of the other two with a simple algebra operation.  They're all the same relationship, described by "Ohm's Law".

==> Current = (potential difference) / (resistance)

==> Potential difference = (current) x (resistance)

==> Resistance = (potential difference) / (resistance)

Which of the following methods has led to the earliest discoveries of massive planets orbiting near their parent stars a. detect
Mrac [35]

Answer:

c. detecting the gravitational effect of an orbiting planet (The Wobble"") by looking for the Doppler shifts in the star's spectrum

Explanation:

In a solar system the mass of the star and planets affect each other's orbital  movements. The center of gravity of a star and a planet is inside the star. This causes the star to be closer and farther from the Earth at different times. Due to this wobble the star appears to be red shifted when it is farther and blue shifted when it is closer.

When the mass of the planet is high, like a hot Jupiter it causes more wobble i.e., change in radial velocity. This makes it easier to detect the planet. The earliest hot Jupiter found by this method is the planet 51 Pegasi b.

If you need 40.0 Nm of torque in order to loosen a nut on a wn
KonstantinChe [14]

Answer:

0.301 m

Explanation:

Torque = Force × Radius

τ = Fr

40.0 Nm = 133 N × r

r = 0.301 m

The mechanic must apply the force 0.301 m from the nut.
