The weight of the other object placed 1 m from the fulcrum that balances the other object is 2.5 N.
<h3>
Principle of moment</h3>
The weight of the second object is determined by applying principle of moment as shown below;
take moment about the pivot,
sum of clockwise moment = sum of anticlockwise moment
F₁r₁ = F₂r₂
5 x 0.5 = F₂ x 1
2.5 N = F₂
Thus, the weight of the other object placed 1 m from the fulcrum that balances the other object is 2.5 N.

Answer: The length L of the wire used to construct the coil is 191.4m
Explanation: Please see the attachments below
Answer:
Slit width is 0.109 mm
Solution:
As per the question:
Wavelength of the light,
Distance from the screen, D = 5.6 m
Bright band in the center, 2x = 8.1 cm
x = 4.05 cm
Now,
To calculate the slit width, w:
From the diffraction:
For small angle:
≈
Also
Thus
Substituting appropriate values in the above eqn:
w = 0.109 mm
Answer:
Light is a source of illumination, whether a natural one (like the sun) or an artificial one (like your lamp). Like light itself, the word can take a lot of different forms — it can be a noun, an adjective, or a verb, and it can mean "bright" or "not heavy".

Answer:
2.86×10⁻¹⁸ seconds
Explanation:
Applying,
P = VI................ Equation 1
Where P = Power, V = Voltage, I = Current.
make I the subject of the equation
I = P/V................ Equation 2
From the question,
Given: P = 0.414 W, V = 1.50 V
Substitute into equation 2
I = 0.414/1.50
I = 0.276 A
Also,
Q = It............... Equation 3
Where Q = amount of charge, t = time
make t the subject of the equation
t = Q/I.................. Equation 4
From the question,
4.931020 electrons has a charge of (4.931020×1.6020×10⁻¹⁹) coulombs
Q = 7.899×10⁻¹⁹ C
Substitute these value into equation 4
t = 7.899×10⁻¹⁹/0.276
t = 2.86×10⁻¹⁸ seconds
