Objects 1 and 2 attract each other with a electrostatic force of 36.0 units. If the charge of Object 1 is doubled, then the new electrostatic force will be units.
If the charge on the object is doubled then the new electrostatic force is 72 units.
What does the term "electrostatic force" mean?Non-contact forces, such as electrostatic forces, pull or push on objects without actually making contact with them. When certain materials are rubbed together, a phenomenon known as "charge" can be transferred from one surface to another. Uncharged items are pulled by charged objects, which in turn may push or pull against other charged ones.
Let q and Q represent the charges on objects 1 and 2, respectively.
Charge Q is separated from charge q by a distance r, and their electrostatic attraction is given by:
F = kqQ/r²
where k is Coulomb's constant
According to the question:
F = 36 units
⇒ kqQ/r² = 36 units
Now, the charge on object 2 is doubled, so it now acquires a 2Q charge.
So the new electrostatic force will be:
F' = kq(2Q)/r²
F' = 2kqQ/r²
F' = 2F = 2×36
F' = 72 units

(A) 0.22kg (B) 0.44kg (C) 0.66kg (D) 0.88kg
I found this formula in an old book.
E = m · c²
It may be useful.
c = 3 x 10⁸ m/s
c² = 9 x 10¹⁶ m²/s²
4 x 10¹⁶ J = m · (9 x 10¹⁶ m²/s² )
m = (4 x 10¹⁶ J) / (9 x 10¹⁶ m²/s²)
m = 0.44 kg (choice-B)

[tex] \\ [/tex]
Newton determined that there is a direct relationship between force and mass. Your weight equals your mass multiplied by the acceleration due to gravity. FALSE 8. A 10-kg object has greater acceleration due to gravity than a 5-kg object.
The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object

Explanation:
1.
A 0.10kg stone is thrown from the edge of an ocean cliff with an initial speed of 21m/s. When it strikes the water below, it is traveling at 45m/s. What is the change in kinetic energy of the stone?
ΔEk = m/2*(V2^2-V1^2) = 0.05*(45^2-21^2) = 79.20 joule
The change in the kinetic energy of the stone is 81.25 J.
The given parameters;
mass of the stone, m = 0.1 kginitial speed of stone, u = 20 m/sfinal velocity of the stone, v = 45 m/sThe initial kinetic energy of the stone is calculated as follows;
K.E = ¹/₂mu²
K.E₁ = ¹/₂ x 0.1 x 20²
K.E₁ = 20 J
The final kinetic energy of the stone is calculated as follows;
K.E₂ = ¹/₂ x 0.1 x 45²
K.E₂ = 101.25 J
The change in the kinetic energy of the stone is calculated as follows;
ΔK.E = K.E₂ - K.E₁
ΔK.E = 101.25 J - 20 J
ΔK.E = 81.25 J
Thus, the change in the kinetic energy of the stone is 81.25 J.

Explanation:
Answer:
9.3N
Explanation:
Fgrav = m • g = 14.7 N (g is 9.8 m/s/s)
a = v2 / R = (4 • Fgrav)/1 = 16 m/s/s
Fnet = m • a = 1.5 kg •16 m/s/s = 24 N, down
Fnet = Fgrav + Ftens, so
Ftens = Fnet - Fgrav
Ftens = 24 N - 14.7 N = 9.3 N

A mass on a spring oscillates with a frequency of 0.1 Hz. The mass is 10 kg. What is the spring constant of the spring?
Answer:

Explanation:
The period of a spring is found using the formula T=2π[tex]\sqrt{\frac{m}{k} }[/tex], where m is the mass and k is the spring constant.
The period can also be found using the formula T=[tex]\frac{1}{f}[/tex], where f is the frequency.

Answer:
Light from the Sun reflecting off the moon bends around particles in Earth's atmosphere and then spreads out.
Explanation:
edg 2021
The diffraction causes "Light from the Sun reflecting off the moon bends around particles in Earth’s atmosphere and then spreads out."
What is diffraction ?Diffraction is a phenomena in which light bends around the corners of obstacle in its path. This happens when the size of the obstacle is comparable to the wavelength of the light.
What is light?Light, often known as visible light, is electromagnetic radiation that falls within the region of the electromagnetic spectrum which the human eye can perceive.
What is moon?Moon can be considered as natural satellite. Moon does not have its own light. It reflects the sun-light which is received by us. The light after reflection from the surface of the moon passes through the atmosphere of Earth wherein it gets scattered by the molecules of the gases present in the earths atmosphere. This gives a fuzzy glow around a full moon.
