Answer:

d is the fastest and c is the slowest

Explanation:

physics

Answer:

Neptune will move the fastest

Mercury will move the slowest

Explanation: Because what ever is closer to a object will move the slowest and something further away will have to go faster to keep up with the object that is closer.

Answer:

The Sun has a north and south pole, just as the Earth does, and rotates on its axis. However, unlike Earth which rotates at all latitudes every 24 hours, the Sun rotates every 25 days at the equator and takes progressively longer to rotate at higher latitudes, up to 35 days at the poles. This is known as differential rotation.

Explanation:

(a) The angular velocity of the system after the collision is 1.61 rad/s.

(b) The kinetic energy before collision is 19.31 J and the kinetic energy after collision is 1.45 J.

The angular velocity of the system is determined by applying the principle of conservation of angular momentum.

Li = Lf

P x r = Ifωf

mv x r = Ifωf

[tex]\omega _f = \frac{mvr}{I_f} \\\\\omega _f = \frac{mvr}{\frac{1}{3}Mr^2 + mr^2 } \\\\\omega _f = \frac{mvr}{r^2(\frac{1}{3}M + m )}\\\\\omega _f = \frac{mv}{r(\frac{1}{3}M + m )}\\\\\omega _f = \frac{0.055 \times 26.5}{1.2(\frac{2.1}{3} \+ \ 0.055)} \\\\\omega_f = 1.61 \ rad/s[/tex]

Kinetic energy before the collision is calculated as follows;

[tex]K.E_i = K.E_{ball} + K.E _{rod}\\\\K.E_i = K.E_{ball} + 0\\\\K.E_i = \frac{1}{2} \times m \times v^2\\\\K.E_i = \frac{1}{2} \times 0.055 \times 26.5^2\\\\K.E_i = 19.31 \ J[/tex]

The kinetic energy after the collision is calculated as follows;

[tex]K.E_f =\frac{1}{2} I_f \omega_ f^2\\\\K.E_f = \frac{1}{2} (\frac{1}{3}Mr^2 + mr^2)\omega _f^2\\\\K.E_f =\frac{1}{2} [\frac{1}{3}(2.1)(1.2)^2 + (0.055)(1.2)^2]\times (1.61)^2\\\\K.E_f = \frac{1}{2} (1.008 + 0.114) \times (1.61)^2\\\\K.E_f = 1.45 \ J[/tex]

because if there is more friction then it will create more hindrance for the current to flow which is ultimately called resistance .

Answer:

t = 9.38 seconds

Explanation:

Given that,

Initial speed of the airplane, u = 0 (at rest)

Final speed of the airplane, v = 77 m/s

Acceleration of the airplane, a = 8.2 m/s²

We need to find the time required for the airplane to accelerate. The formula of acceleration is given by :

[tex]a=\dfrac{v-u}{t}\\\\t=\dfrac{v-u}{a}\\\\t=\dfrac{77-0}{8.2}\\\\t=9.38\ s[/tex]

So, the time taken by the airplane is 9.38 seconds.

Answer:

Ffriction = 90 N

coefficient = 0.3

Explanation:

First, note that the sum of all the forces in the x directions equals the mass multiplied by the acceleration in the x direction.

assuming the direction of the pulling force is positive,

243 N - Ffriction = m * a

m= 30.6 kg

a= 5 m/s/s

Ffriction= 243 - m*a

Ffriction= 243 - (30.6)(5)

Ffriction=90 N

The force of friction is equal to the coefficient of friction multiplied by the normal force on the object. Because the pulling force is completely horizontal, the normal force of the object is equal to its weight, which is m * g, or (30.6 kg)(9.8 m/s/s) = 299.88 N

Ffriction = coefficient * Fnormal

90 = coefficient * 299.88

coefficient = 0.3

Answer:

I = 7.826A

R = 29.38 Ω

Explanation:

First, let us find the current of the microwave.

Let us use the below formula for that.

Power = Voltage × Current

Current = Power ÷ Voltage

             = 1800w ÷ 230v

             = 7.826 A

And now let us find the resistance using the below formula.

Voltage = Current × Resistance

Resistance = Voltage ÷ Current

                   = 230V  ÷ 7.826A

                    = 29.38 Ω

Answer:

D, valence electrons.

Explanation:

Since the number of shells are dependent on the number of valence electrons, which determines the period of the element. Because each shell of an element holds a total of 8 valence electrons, there is a chemical association that is being made between the outer electrons and the atom.

Answer:

The correct answer is D. Its valence electrons.

Explanation:

The valence electrons are those that participate in reactions with other elements.  The fewer valence electrons that an element has, the less stable it becomes; an element with a full valence electron shell does not frequently interact with other elements.  In this way, the valence electrons determine the chemical properties of an element.
