What is formula for finding period of a planet if its mass is found by sending a spacecraft

Explanation:

Scientists sometimes call our region of space the "Goldilocks Zone" because it appears to be just right for life. As noted earlier, Earth's average distance to the Sun is about 93 million miles (150 million kilometers) from the Sun.

The color and their corresponding wavelength ranges are given in the table below.

[tex]\begin{gathered}\begin{gathered}\boxed{\begin{array}{c|c} \bf colour & \bf wavelength\\ \\ \frac{\qquad \qquad}{} & \frac{\qquad \qquad}{} \\ \sf red & \sf 650 - 700 \\ \\ \sf orange & \sf 600 - 650 \\ \\ \sf yellow & \sf \: 580 - 600 \\ \\ \sf green & \sf 550 - 580 \\ \\ \sf cyan & \sf 500 -550 \\ \\ \sf \: blue& \sf450 - 500\\ \\ \sf indigo & \sf 425- 450\\ \\ \sf violet & \sf 380 - 425 \end{array}} \\ \end{gathered}\end{gathered}[/tex]

After observing the table, we can predict that wave is most likely appear Indigo.

Note- The wavelengths boundaries between the colours are not very sharp and they form a continuous spectrum.

The distance of the canoeist from the dock is equal to length of the canoe, L.

The principle of conservation of linear momentum states that the total momentum of an isolated system is always conserved.

v(m₁ + m₂) = m₁v₁ + m₂v₂

where;

v is the velocity of the canoeist and the canoe when they are together

The distance traveled by the canoeist from the back of the canoe to the front of the canoe is equal to the length of the canoe.

Thus, the distance of the canoeist from the dock is equal to length of the canoe, L.

Explanation:

Given that,

Initial speed, u = 20 km/s

Acceleration of plane, a = 2.4 km/h²

Time, t = 59 s

We need to find the expression to find the final velocity of an object.Let the final velocity is v.

Using the second equation of kinematics:

[tex]\Delta s=ut+\dfrac{1}{2}at^2[/tex]

a is acceleration, [tex]a=\dfrac{v-u}{t}[/tex]

So,

[tex]\Delta s=ut+\dfrac{1}{2}\times \dfrac{v-u}{t}\times t^2\\\\\Delta s=ut+\dfrac{1}{2}(v-u)t\\\\\Delta s=\dfrac{2ut+vt-ut}{2}\\\\\Delta s=\dfrac{vt+ut}{2}\\\\\Delta s=(\dfrac{v-u}{2})t[/tex]

We can use the above formula to find the final velocity (v) of the plane.

Answer:

3.5 KJ

Explanation:

Energy balance equation is given as;

E_in - E_out = ΔE_system

Thus;

Q_in = (m_2•u_2) - (m_i•h_i)

Now, m_i = m_2

Tbus;

Q_in = (m_2•u_2) - (m_2•h_i)

Q_in = m_2(u_2 - h_i)

Now mass of the air in the bottle is given as;

m_2 = (P_2•V)/(R•T2)

From table A-1 attached, R = 0.287 KJ/Kg.k

We are given;

P_2 = 100 kPa

V = 35 L = 0.035 m³

T2 = 22°C = 22 + 273 K = 295 K

Thus;

m_2 = (100 × 0.035)/(0.287 × 295)

m_2 = 0.04134 kg

Now, from table A-17 attached, at Temperature of 295 K, we have;

Internal energy; u2 = 210.49 KJ/Kg

Enthalpy; h_i = 295.17 KJ/Kg

From earlier, we saw that;

Q_in = m_2(u_2 - h_i)

Thus;

Q_in = 0.04134(210.49 - 295.17)

Q_in = -3.5 KJ

Thus, Q_out = 3.5 KJ

So, the net heat transfer = 3.5 KJ

Hi there!

Recall the following.

Capacitors in series:
[tex]C_T = \frac{1}{C_1} + \frac{1}{C_2} +...+ \frac{1}{C_n}[/tex]

Capacitors in parallel:

[tex]C_T = C_1 + C_2 + ... + C_n[/tex]

Begin by solving for the resulting capacitance of both paths.

Path on the left:
[tex]\frac{1}{C_T} = \frac{1}{2C} + \frac{1}{C} = \frac{3}{2C}\\C_T = \frac{2C}{3}[/tex]

Path on the right:
[tex]\frac{1}{C_T} = \frac{1}{C} + \frac{1}{3C} = \frac{4}{3C}\\\\C_T = \frac{3C}{4}[/tex]

Now, since we ADD capacitors in parallel, we can add the resulting capacitances together:
[tex]C_T = \frac{2C}{3} + \frac{3C}{4}[/tex]

Substitute in 12 F for C and solve.

[tex]C_T = \frac{2(12)}{3} + \frac{3(12)}{4} = \frac{24}{3} + \frac{36}{4} = 8 + 9 = \boxed{17F}[/tex]

The resistive force from load of the kettle lifted by the arm is determined from principle of moment and the magnitude is 71 kg.

The moment of force about a point is the product of applied force and the perpendicular distance of the force action. The moment of force about a point is equal to the torque exerted by the force.

τ = Fr

where;

F₁r₁ = F₂r₂

925(22.86) = F₂(30.38)

696 N = F₂

in kg, m = 696/9.8 = 71 kg

Thus, the resistive force from the applied force and distance is 71 kg.

   The mass of the Chinook salmon is [tex]m  =  46.0 \ kg[/tex]

   The  upward velocity in water is  [tex]u =  3.00 \ m/s[/tex]

    The  upward velocity in air is [tex]v =  5.80 \ m/s[/tex]

Answer:

It's B (electrical force and magnetic force) I just took the test.

The two forces can Danielle's device produce will be an electrical force and magnetic force. Daniel forms a coil resulting in both forces.

Electric Force on the particle is defined as the application of the force field of one particle on another particle. It is a type of virtual force. it is the ratio of voltage to the distance between them.

Danielle took an iron nail and wrapped thin copper wire around it, then connected the ends of the copper wire to a battery.

A coil of wire that carries an electric current is a solenoid. A solenoid is an electromagnet formed by a helical coil of wire. Which generates a magnetic field when an electric current is passed through the coil.

A solenoid is a form of coil that produces a magnetic field when the electric current is passed through it. A solenoid is created when a conductive wire is used to make a loop.
