Which phase of the moon occurs after a waxing gibbous?.
Four identical particles of mass m are mounted at equal intervals on a thin rod of length l and mass m, with one mass at each end of the rod.
Answer:
Moment of inertia at distance L / 2 from center
I1 = M (L / 2)^2 = M L^2 / 4
I2 = M (L / 6)^2 = M L^2 / 36 at a distance of L / 6
I (1/2 rod) = I1 + I2 = M L^2 (1/4 + 1/36) = M L^2 (9 + 1)/ 36 = 5/ 18 M L^2
I for entire rod = 2 I (1/2 rod) = 5 / 9 M L^2

You are generating traveling waves on a stretched string by wiggling one end. If you suddenly begin to wiggle more rapidly without appreciably affecting the tension, you will cause the waves to move down the string.
Answer:
At the same speed as before
Explanation:
Speed is dependent on the tension in the string, and since the tension isn't changing, the speed of the waves will also not change.

Explanation:
the weight of an object is its force exerted by gravity.
on earth we take gravitational acceleration to be 9.8 m/s^2
so the weight of an object on earth is given by F = mg
hence,
F = 90 × 9.8
F = 882 Newtons (weight on earth)
gravitational acceleration on the moon is equal to 9.8/6. so, we can just use the same formula to find the weight on the moon.
F = 90 × 9.8/6
F = 147 Newtons (weight on the moon)

An astronaut is planning a trip to a newly-discovered planet. According to 2 points
the Law of Universal Gravitation, the astronaut's weight on the new planet
will be greater than his weight on Earth if:
-the new planet has less gravity than Earth.
-the new planet has the same gravity as Earth.
-the new planet has more gravity than Earth.
-the gravity of the planet doesn't matter.
-Weight is the same everywhere in the
universe.
Answer:
The new planet has more gravity
Explanation:
gravity force = G m1 m2 / r^2
decresing r or increasing the planet mass will increase the force
21
The law of universal gravitation can be expressed as
where F is the force of attraction, G is the universal graviational constant (6.674x10-11
N m2 kg-2) m1 is the mass of the first object, m2 is the mass of the second object, and r is th
distance between the centers of the two objects.

(4 Points)

72
The attractive force between sugar and flour by using Newton's law of gravitation is 14.229 × 10⁻¹¹ N.
What is the Universal law of Gravitation?This law states that every object in the universe attracts each other. The attractive force is directly proportional to the masses of two objects and inversely proportional to the square of the distance between them.
This law is applicable to all the objects with mass in the universe and hence it is called the Universal law of gravitation. It was proposed by Newton.
The attractive force, F =G (m₁×m₂ / r²). m₁,m₂ is the masses of two objects and r is the distance between two masses. G is the gravitational constant and is equal to 6.67×10⁻¹¹Nm²kg⁻².
From the given,
Gravitational constant,G = 6.67×10⁻¹¹Nm²kg⁻²
m₁ (mass of sugar) = 1.2 kg
m₂ (mass of flour) = 9.4 kg
r (distance of separation) = 2.3 m
The attractive force, F = G (m₁×m₂ / r²)
F = 6.67×10⁻¹¹×(1.2×9,4) / (2.3)²
= 14.229 × 10⁻¹¹ N
Thus, the attractive force F = 14.23 × 10⁻¹¹ N.

Is the mass of an alpha particle greater than, less than, or equal to the mass of an electron?.
The mass of an alpha particle greater than the mass of an electron. Hence option A is correct.
What is alpha particle ?The alpha particle is a positively charged particle that is similar to the nucleus of the helium-4 atom and is spontaneously released by some radioactive substances. It is made up of two protons and two neutrons bonded together and has a mass of four units and a positive charge of two. Ernest Rutherford discovered and named alpha particles (1899), which he and colleagues employed in studies to examine the structure of atoms in thin metallic foils. This investigation produced in the original notion of the atom (1909-11) as a miniature planetary system with negatively charged particles (electrons) circling a positively charged nucleus. Later, in the first artificially created nuclear transmutation (1925), Patrick Blackett blasted nitrogen with alpha particles, converting it to oxygen.
Alpha particle is heavier than the electron cause alpha particle has 2 neutron and two protons which makes it heavier.
Hence option A is correct.

Question :-
What is the Speed of a Wave that has a Frequency of 250 Hertz and a Wavelength of 1.5 meter ?Answer :-
Speed of the Wave is 350 m/s .Explanation :-
As per the provided information in the given question, we have been given that the Frequency of the Sound Wave is 250 Hertz. Its Wavelenght is given as 1.5 Meter. And, we have been asked to calculate the Speed of the Wave.
For calculating the Speed , we will use the Formula :-
