An apparatus like the one Cavendish used to find G has large lead balls that are 5.2 kg in mass and small ones that are 0.046 kg.
Ber [7]

Answer:

The magnitude of gravitational force between two masses is 4.91\times 10^{-9}\ N.

Explanation:

Given that,

Mass of first lead ball, m_1=5.2\ kg

Mass of the other lead ball, m_2=0.046\ kg

The center of a large ball is separated by 0.057 m from the center of a small ball, r = 0.057 m

We need to find the magnitude of the gravitational force between the masses. It is given by the formula of the gravitational force. It is given by :

F=G\dfrac{m_1m_2}{r^2}\\\\F=6.67259\times 10^{-11}\times \dfrac{5.2\times 0.046}{(0.057)^2}\\\\F=4.91\times 10^{-9}\ N

So, the magnitude of gravitational force between two masses is 4.91\times 10^{-9}\ N. Hence, this is the required solution.

An ohmic dipole of resistance 100 ohm is crossed by a current of intensity 120 ma. Calculates the voltage across this chemical d
Sedaia [141]

Answer:

12.0 Volt

Explanation:

Step 1: Given data

Resistance of the ohmic dipole (R): 100 Ohm

Intensity of current (I): 120 mA (0.120 A)

Step 2: Calculate the voltage (V) across this chemical dipole

To calculate the voltage across the ohmic dipole, we will use Ohm's law.

I = V/R

V = I × R

V = 0.120 A × 100 Ohm = 12.0 V

explain why astronauts around the earth either in spaceship, a space station, or on a spacewalk appear to be weightless but are
IrinaK [193]

Answer:

Zero gravity

Explanation:

Astronauts around the earth either in spaceship, a space station or on a space walk appear to be weightless because of the zero gravity in such environment.

Weight is a function of the mass and acceleration due to gravity a body has.

   Weight  = mass  x  acceleration due to gravity

In a place where acceleration due to gravity is 0, the weight would be zero and a person would appear to be weightless.

A container explodes and breaks into three fragments that fly off 120° apart from each other, with mass ratios 1: 4: 2. If the f
RSB [31]

Answer:

V₂ = 1.5 m/s

Explanation:

given,

speed of the first piece = 6 m/s

speed of the third piece = 3 m/s

speed of the second fragment = ?

mass ratios = 1 : 4 : 2

fragment break  fly off = 120°

α = β = γ  = 120°

sin α = sin β = sin γ = 0.866

using lammi's theorem

\dfrac{A}{sin\alpha}=\dfrac{B}{sin\beta}=\dfrac{C}{sin\gamma}

A,B and C is momentum of the fragments

\dfrac{m\times 6}{0.866}=\dfrac{4m\times v_2}{0.866}=\dfrac{2m\times 3}{0.866}

4 x V₂ = 2 x 3

V₂ = 1.5 m/s

What mechanisms do astronomers believe is responsible for making the Sun's outer atmosphere so much hotter than its photosphere?
IrinaVladis [17]

Answer:

magneto hydrodynamic( MHD) waves

Explanation:

The surface of the Sun transmits magneto hydrodynamic( MHD) waves to its atmosphere. These waves carry energy from the sun's surface to its atmosphere ( Corona) and heat up the atmosphere to such extent that its temperature rises to many time than that of the surface temperature of the Sun.
