If the gravitational force between a planet of mass M and a satellite of mass m at distance is 2.5 * 10 ^ 3 * N what is the force exerted on a larger satellite of mass 2m , at a distance 0.8r away from planet M ?
Answer:
F = 7.8 10³ N
Explanation:
For this exercise we will use the law of universal Gravitational
F = G M m / r²
for initial conditions
F₀ = G M m₀ / r₀²
They tell us that the mass changed at m = 2m distance at r = 0.8r₀
we substitute
F = G M 2m₀ / (0.8 r₀) ²
F = (GM m₀/ r₀²) [tex]\frac{2}{0.64}[/tex]
F = 3.125 F₀
let's calculate
F = 3.125 2.5 10³
F = 7.8125 10³ N
An astronaut weighs 200 N on the Moon where gravity is 1.62 m/s/s. Find his weight on Earth. HELP PLEASE FAST
Answer:
the weight of the astronaut on Earth is 1209.88 N
Explanation:
Given;
weight of the astronaut, W = 200 N
acceleration due to gravity on moon, g = 1.62 m/s²
Apply Newton's second law of motion to determine the mass of the astronaut;
F = ma = mg
m = F/g
m = 200 / 1.62
m = 123.457 kg
The weight of the astronaut on Earth is calculated as follows;
F = mg
where;
g is acceleration due to gravity on Earth = 9.8 m/s²
F = 123.457 x 9.8
F = 1209.88 N
Therefore, the weight of the astronaut on Earth is 1209.88 N
If a light ray hits a plane mirror at 20°. What is the angle of reflection?
Answer:
This question is vague because it doesn't specify whether 20° is the angle of incidence or the angle the ray makes with the surface
But If we consider 20° as the angle of Incidence...
The Angle of Reflection = 20° also
Because
From The Law of Reflection
Angle of Incidence = Angle of Reflection
Explanation:
A 650 × 10–4 F capacitor stores 24 × 10–3 of charge. What is the potential difference between the plates?
Answer:
0.369 V
Explanation:
Given :
Capacitance ( c ) = 650 × 10–4 F
Charge ( q ) = 24 × 10–3 C
We are asked to find potential difference ( v )!
We know:
q = c v
= > v = q / c
Putting values here we get:
= > v = ( 24 × 10–3 ) / ( 650 × 10–4 ) V
= > v = 240 / 650 V
= > v = 24 / 65 V
= > v = 0.369 V
Therefore, potential difference between the plates is 0.369 V

What is an atom called after it was proven wrong
Answer:
An atom is the smallest unit of ordinary matter that forms a chemical element.
Matter is composed of very tiny or microscopic particles called "Atom".
(According to Dalton atomic theory some of his principles were wrong and later was corrected but the definition of an atom was right in his theory).

The moon Ariel orbits Uranus at a distance of 1.91 x 108 m once every 2.52 days. Use that data to calculate the mass of Uranus. [?] x 10kg
Mu = 8.66 × 10^25 kg
Explanation:
centripetal force = gravitational force
[tex]m \frac{ {v}^{2} }{r} = (grav.const) \frac{m \times mu}{ {r}^{2} } [/tex]
where
m = mass of moon Ariel
mu = mass of Uranus
r = radius of Ariel's orbit
v = Ariel's velocity around Uranus
To find the velocity, we need to find the circumference of the no orbit and then divide it by the period (2.52 days):
circumference = 2πr = 2π×(1.91 × 10^8 m)
= 1.2 × 10^9 m
period = 2.52 days × (24 h/1 day)×(3600 s/1 hr)
= 2.18 × 10^5 s
v = (1.2 × 10^9 m)/(2.18 × 10^5 s)
= 5.5 × 10^3 m/s
(5.5 × 10^3 m/s)^2/(1.91 × 10^8 m) = (6.67 × 10^-11 m^3/kg-s^2)Mu/(1.91 × 10^8 m)^2
Solving Mu,
Mu = 8.66 × 10^25 kg
Two parallel plates of area 7.34 x 10^-4 m^2 have 5.83 x 10^-8 C of charge placed on them. A 6.62 x 10^-6 C charge q1 is placed between the plates. What is the magnitude of the electric force on q1? Hint: How is force related to the field? (Unit = N)
Answer:
* if the two plates have the same charge sign F_net = 0
*if one plate is positive and the other is negative F_net = 59.4 N
Explanation:
The electric field created by a parallel plate is
E = [tex]\frac { \sigma }{2 \epsilon_o }[/tex]
where sigma is the charge density
σ = Q / A
we substitute
E = [tex]\frac{Q}{A \ 2 \epsilon_o }[/tex]
E = [tex]\frac{ 5.83 \ 10^{-8} }{7.34 \ 10^{-4}\ 2 \ 8.5 \ 10^{-12} }[/tex]
E = 4.487 10⁶ N / C
the electric force is
F = E / q
in this force it is a vector, so if the charges are of the same sign they repel and if they are of the opposite sign they attract. In this case, the test load is between the two plates that have the same load sign, so the forces are in the opposite direction.
* if the two plates have the same charge sign
F_net = F₁ - F₂
F_net = q (E₁ -E₂)
since the electric field does not depend on the distance
E₁ = E₂
in consecuense
F_net = 0
In a more interesting case
*if one plate is positive and the other is negative
F_net = F₁ + F₂
F_net = q (E₁ + E₂) = 2 q E₁
F_net = 2 6.62 10⁻⁶ 4.487 10⁶
F_net = 59.4 N
net force goes from positive to negative plate
Answer:
59.4 N

P = 5880 J
Explanation:
Given that,
The mass of the block, m = 30 kg
The block is sitting at a height of 20 m.
The block will have gravitational potential energy. The formula for gravitational potential energy is given by :
[tex]P=mgh\\\\=30\times 9.8\times 20\\\\=5880\ J[/tex]
So, the required potential energy is equal to 5880 J.
A spring stretches 2 meters when a 12 N force is acting on it. What is the spring constant (k)? 10 N/m 0.17 N/m 2 N/m 6 N/m
Answer:
Explanation:
Hooke's Law is linear; mathematically, it looks like this:
F = -kΔx where k is the spring constant. Filling in and solving for k:
12 = -k(-2) so
k = 6N/m
