5.4*10^-19 C
Explanation:
For the purposes of this question, charges essentially come in packages that are the size of an electron (or proton since they have the same magnitude of charge). The charge on an electron is -1.6*10^-19
Therefore, any object should have a charge that is a multiple of the charge of an electron - It would not make sense to have a charge equivalent to 1.5 electrons since you can't exactly split the electron in half. So the charge of any integer number of electrons can be transferred to another object.
Charge = q(electron)*n(#electrons)
Since 5.4/1.6 = 3.375, we know that it can not be the right answer because the answer is not an integer.
If you divide every other option listed by the charge of an electron, you will get an integer number.
(16*10^-19 C)/(1.6*10^-19C) = 10
(-6.4*10^-19 C)/(1.6*10^-19C) = -4
(4.8*10^-19 C)/(1.6*10^-19C) = 3
(5.4*10^-19 C)/(1.6*10^-19C) = 3.375
(3.2*10^-19C)/(1.6*10^-19C) = 2
etc.
I hope this helps!
A planet was discovered by the Kepler space telescope. The planet had a mass of8.0 x 10^27kg and a radius of 1.0 x 10^8m. What is the value of the acceleration due to gravity on the surface of the planet?
Answer:
[tex]g=53.36\ m/s^2[/tex]
Explanation:
Given that,
The mass of the planet, [tex]M=8\times 10^{27}\ kg[/tex]
The radius of the planet, [tex]R=10^8\ m[/tex]
We need to find the value of the acceleration due to gravity on the surface of the planet. The formula for the acceleration due to gravity is given by :
[tex]g=\dfrac{GM}{R^2}\\\\g=\dfrac{6.67\times 10^{-11}\times 8\times 10^{27}}{(10^8)^2}\\\\g=53.36\ m/s^2[/tex]
So, the value of acceleration due to gravity on the surface of the plate is equal to [tex]53.36\ m/s^2[/tex].
A ball was thrown from the ground at an angle 0 with a velocity v. The ball reached a maximum height of 8 m and a maximum range of 15 m. Calculate the value of 0. Let g=1 m/s²
Answer:
θ ≈ 65°
Explanation:
From the question given above, the following data were obtained:
Maximum height (H) = 8 m
Range (R) = 15 m
Initial velocity (u) = v
Angle θ =?
H = u²Sine²θ / 2g
8 = v²Sine²θ / 2g
Cross multiply
8 × 2g = v²Sine²θ
16g = v²Sine²θ
Divide both side by Sine²θ
v² = 16g / Sine²θ.... (1)
R = u²Sine2θ / g
15 = v²Sine2θ / g
Cross multiply
15 × g = v²Sine2θ
15g = v²Sine2θ
Divide both side by Sine2θ
v² = 15g / Sine 2θ... (2)
Summary:
v² = 16g / Sine²θ.... (1)
v² = 15g / Sine 2θ... (2)
Equate equation 1 and 2
16g / Sine²θ = 15g / Sine 2θ
16 / Sine²θ = 15 / Sine 2θ
Recall:
Sine²θ = SineθSineθ
Sine 2θ = 2SineθCosθ
16 / Sine²θ = 15 / Sine 2θ
16 / SineθSineθ = 15 / 2SineθCosθ
16 / Sineθ = 15 / 2Cosθ
Cross multiply
15 × Sineθ = 16 × 2Cosθ
15Sineθ = 32Cosθ
Divide both side by Cosθ
15Sineθ / Cosθ = 32
Divide both side by 15
Sineθ / Cosθ = 32/15
Recall:
Sineθ / Cosθ = Tanθ
Sineθ / Cosθ = 32/15
Tanθ = 32/15
Tanθ = 2.1333
Take the inverse of Tan
θ = Tan¯¹ 2.1333
θ ≈ 65°

If a bottle is being squeezed with a force of 10 Newtons and the area of the bottle is 15
inches. What is the pressure??
question: Please help!!!
If a bottle is being squeezed with a force of 10 Newtons and the area of the bottle is 15
squared inches. What is the pressure??
Answer:
1025.64 N/m²
Explanation:
Pressure: This can be defined as the ratio of force to area. The si unit of pressure is N/m².
From the question,
P = F/A........................ Equation 1
Where F = Force, A = Area.
Given: F = 10 Newtons, A = 15 Squared Inches = (15×0.00065) = 0.00975 m²
Substitute these values into equation 1
P = 10/0.00975
P = 1025.64 N/m²
Hence the pressure of the bottle is 1025.64 N/m²

580 nm light shines on a double slit
with d = 0.000125 m. What is the
angle of the third dark interference
minimum (m = 3)?
(Remember, nano means 10-9.)
(Unit = deg)
Explanation:
Given that,
The wavelength of light = 580 nm
Slit separation, d = 0.000125 m
We need to find the angle of the third dark interference. For the dark fringe,
[tex]d\sin\theta=(m+\dfrac{1}{2})\lambda[/tex]
Put m = 3 and other values also.
[tex]d\sin\theta=(3+\dfrac{1}{2})\lambda\\\\d\sin\theta=\dfrac{7\lambda}{2}\\\\\sin\theta=\dfrac{7\lambda}{2d}\\\\\theta=\sin^{-1}(\dfrac{7\lambda}{2d})\\\\\theta=\sin^{-1}(\dfrac{7\times 580\times 10^{-9}}{2\times 0.000125 })\\\\\theta=0.93^\circ}[/tex]
So, the angle is 0.93°.
Answer: 0.665 deg
Explanation:
m=3
lambda= 580
d (converted to nanometers)= 125000
Using the equation of angle=arcsine of m-1/2 times lambda divided by d, filled in it would be arcsine of 3-1/2 times 580 over 125000.
Which statement is the best interpretation of the ray diagram shown below?
A. A concave lens forming a larger, virtual image
B. A concave lens forming a larger, real image
C. A concave mirror forming a larger, virtual image
O D. A concave mirror forming a larger, real image
Answer:
a concave lens forms a smaller, real image. { a p e x :)) }
Explanation:
hey, friend! this is the answer, but make sure that, next time, you include the diagram to make it easier for us to help you, okay?
A concave lens forming a larger real or virtual image and Concave mirrors form both real and virtual images. therefore all statements are correct. Therefore these can be interpreted by using Ray diagram.
What is Ray diagram ?A ray diagram is a diagram that shows path taken by light in order to see a point on the image of an object. Ray diagram uses lines with arrows to show reflected and incident ray.
A concave lens is a lens that diverges a straight light beam from the source to a diminished, upright, virtual image. It can form both real and virtual images. concave lens has curve on both side. The lens having only one side plane and other is curved inside, the les is called as planoconcave lens.
Concave mirror can form both virtual and real image that depends on the distance between the mirror and object. We get virtual and magnified image When the object is placed very close to the mirror. when distance between the object and mirror is increased, image gets diminished and real.
Both concave lens and mirror form both real and virtual images that's depend on the distance.
Hence all statements are correct.

A 5.00 kg block of metal with
c = 650 J/(kg*C) at 80.0 °C comes
in contact with a 1.25 kg glass
block at 20.0 °C. They come to
equilibrium at 63.9 °C. What is the
specific heat of the glass?
Answer:
953.5 J/kg.°C
Explanation:
From the question,
Heat lost by the metal = heat gained by the glass.
cm(t₁-t₃) = c'm'(t₃-t₂)................. Equation 1
Where c = specific heat capacity of the metal, m = mass of the metal, c' = specific heat capacity of the glass, m' = mass of the glass, t₁ = initial temperature of metal, t₂ = initial temperature of glass, t₃ = Equilibrium temperature
Make c' the subject of the equation
c' = cm(t₁-t₃)/m'(t₃-t₂)................ Equation 2
Given: m = 5 kg, c = 650 J/kg.°C, m' = 1.25 kg, t₁ = 80 °C, t₂ = 20 °C, t₃ = 63.9 °C
Substitute these values into equation 2
c' = 5×650(80-63.9)/1.25(63.9-20)
c' = (5×650×16.1)/(1.25×43.9)
c' = 52325/54.875
c' = 953.5 J/kg.°C
Answer:
960 J/(kg*C)

Answer:
50 N
Explanation:
We are given;
Force on larger piston; F2 = 5000 N
Ratio of diameter of smaller piston to larger piston = 1:10
Now, formula for force on smaller piston which we will denote with F1 is gotten from;
F1 = F2 × A1/A2
Now, A1 = π(d1)²/2
A2 = π(d2)²/2
Thus:
F1 = F2 × (π(d1)²/2)/(π(d2)²/2)
This gives;
F1 = F2 × (d1/d2)²
Plugging in the relevant values;
F1 = 5000 × (1/10)²
F1 = 50 N
The man rolls the cupboard at a steady speed from the lorry to the house. The friction force in the wheels is 40 N. State the force with which the man has to push.
Answer:
40N
Explanation:
Using the newton's second law of motion
\sum Fx = max
Fm - Ff = max
Fm is the applied force
Ff is the frictional force
m is the mas of the cupboard
ax is the acceleration
Since the speed from the lorry is steady, ax = 0m/s^2
Also Ff = 40N
Substitute into the formula;
Fm - 40 = m(0)
Fm - 40 = 0
Add 40 to both sides
Fm - 40 + 40 = 0 + 40
Fm = 40N
Hence the force with which the man applied to push is 40N

Point charges q1 and q2 are separated by a distance of 60 cm along a horizontal axis.
The magnitude of q1 is 3 times the magnitude of q2. At which point a on the axis is the
electric field zero?
NEED ANSWERS NOW
Answer:
38 cm from q1(right)
Explanation:
Given, q1 = 3q2 , r = 60cm = 0.6 m
Let that point be situated at a distance of 'x' m from q1.
Electric field must be same from both sides to be in equilibrium(where EF is 0).
=> k q1/x² = k q2/(0.6 - x)²
=> q1(0.6 - x)² = q2(x)²
=> 3q2(0.6 - x)² = q2(x)²
=> 3(0.6 - x)² = x²
=> √3(0.6 - x) = ± x
=> 0.6√3 = x(1 + √3)
=> 1.03/2.73 = x
≈ 0.38 m = 38 cm = x

Una niña juega a saltar con la cuerda, realizando 40 saltos en un minuto. ¿Cuál de los siguientes conceptos se asocia de mejor manera con lo descrito en la situación?
Answer:
he angular velocity w = 4.19 rad / s
Explanation:
The girl is synchronized with the movement of the rope, therefore we can describe the movement of the girl with the angular velocity
w = θ/t
if we fear 40 jumps and each one is a revolution
θ = 40 2pi = 80π radiation
t = 1 min = 60 s
w = 80π / 60
w = 4.19 rad / s
this must be the same angular velocity of the rope
