Answer:
a. Many strong friends
Explanation:
The Characteristics of Self-Actualization. They are comfortable with themselves and they appreciate other people for who they are. Self actualized people are also more likely to have what are known as peak experiences. These are profound moments of fulfillment to leave a person with a sense of awe.
Answer:
5.76 μC
Explanation:
The induce emf, ε = -ΔΦ/Δt where ΔΦ = change in magnetic flux = NAΔB where N = number of turns of coil = 1000, A = cross-sectional area of coil = πd²/4 where d = diameter of coil = 2 cm = 2 × 10⁻² m and ΔB = change in magnetic field strength = B' - B where B' = final magnetic field = 0 T and B = initial magnetic field strength = 0.011 T. So, ΔB = 0 T - 0.011 T = -0.011 T
So, ε = -ΔΦ/Δt
ε = -NAΔB/Δt
ε = -NAΔB/Δt
Also ε = iR where i = current and R = combined resistance of circular coil and galvanometer = 200 Ω + 400 Ω = 600 Ω (since they are in series)
So, iR = -NAΔB/Δt
iΔt = -NAΔB/R
Δq = -NAΔB/R where Δq = charge = iΔt
substituting the values of the variables into the equation, we have
Δq = -1000 × π(2 × 10⁻² m)²/4 × -0.011 T/600 Ω
Δq = -1000 × 4π × 10⁻⁴ m²/4 × -0.011 T/600 Ω
Δq = 0.011π × 10⁻¹ m²T/600 Ω
Δq = 0.03456 × 10⁻¹ m²T/600 Ω
Δq = 5.76 × 10⁻⁶ C
Δq = 5.76 μC
The frictional force between the block and the surface is 6 N
Explanation:
We can solve this problem by applying Newton's second law of motion, which states that the net force on an object is equal to the product between its mass and its acceleration:
where
is the net force
m is the mass
a is the acceleration
For the block in this problem, we have:
, because its acceleration is zero
, since the net force is given by the difference between the applied force (in the forward direction) and the frictional force (in the backward direction)
Therefore Newton's second law becomes
Which means
And since the applied force is , this means that the friction force is also 6 N:

Answer:
Image distance of the bug is - 0.4 m
Magnification is 5 times
Image is real and inverted
Solution:
As per the question:
The focal length of the lens, f = 0.1 m
Distance of the bud from the lens, v = 0.08 m
Now,
Using the lens maker formula:
where
v' = distance of the bug's image from the lens
Now,
v' = - 0.4 m
Now,
Magnification of the bug's image is given by:
m =
m =
Since, negative sign shows that inverted image is formed and positive value of magnification shows that real image is formed.
Answer:
a. I₁ = 0.1171875 kg * m²
b. I₂ = 0.288 kg * m²
Explanation:
a. m₁ = 2.5 kg, L₁ = 0.75 m
The rotational inertia about an axis perpendicular to it and passing through its center
I₁ = ¹/₁₂ * M * L²
I₁ = ¹/₁₂ * 2.5 kg * (0.75m)²
I₁ = 0.1171875 kg * m²
b. m₂ = 3 kg , d₁ = 0.38 m
The rotational inertia tangent to the edge of the sphere
I₂ = ²/₃ * M * R²
I₂ = ²/₃ * 3 kg * (0.38m)²
I₂ = 0.288 kg * m²
