Two massive objects are fixed in position. A third object is placed directly between the first two at the position at which the
ivanzaharov [21]

Answer:

Explanation:

Be M1 and M2 the two massive objects and m the third one

The gravitational force over the third object at the beginning is zero (assuming that the position of the third object is x=0)

F_{m}=-G\frac{mM_{1}}{x_{1}^{2}}-G\frac{mM_{2}}{x_{2}^{2}}=0

when the third object is displaced we have that the new position is x=Δx. Hence

F_{m}=-G\frac{mM_{1}}{(-x_{1}+\Delta x)^{2}}-G\frac{mM_{2}}{(x_{2}-\Delta x)^{2}}

I attached a scheme of the system

I hope this is useful for you

Regards

Answer: τ = 0

Explanation:

At constant angular velocity there is no angular acceleration therefore no torque.

τ = Iα

A stream of doubly ionized particles (2 protons) moves at a velocity of 3.0 × 104 m/s perpendicularly to a magnetic field of 0.0
max2010maxim [7]

The force on a charged particle on a magnetic field is given by:

F=Bqv\sin\theta

where B is the magnitude of the field, q is the charge of the particle, v is its velocity and θ is the angle between the field and the velocity of the particle.

In this case we have that:

• The magnitude of the field is 0.09 T.

,

• The charge of the particle is 3.2 x 10 –19C .

,

• The velocity is  3.0 × 10 4 m/s

,

• The angle between the field and the velocity is 90°, since they are perpendicular.

Plugging these we have:

\begin{gathered} F=(0.09)(3.2\times10^{-19})(3\times10^4)\sin90 \\ F=8.64\times10^{-16}\text{ N} \end{gathered}

Therefore, the force on the charge is:

F=8.64\times10^{-16}\text{N}

Complete the steps for converting 3.6 gallons per minute to milliliters per second. (1 gallon = 3.79 liters and 1 liter = 1,000
AlekseyPX

Given that,

Capacity = 3.6 gallons per minutes

Convert it into milliliters per seconds

Since, 1 gallon = 3.79 liters

1 liters = 1000 milliliters

Capacity= (3.6*3.79*1000)/(60)

Capacity = 227.4 milliliters per second.
