Answer:

Stocks give you partial ownership in a corporation, while bonds are a loan from you to a company or government. The biggest difference between them is how they generate profit: stocks must appreciate in value and be sold later on the stock market, while most bonds pay fixed interest over time.

None

Thepotemich [5.8K]

C=40cm
f=C/2=40/2=20

$\\ \sf\longmapsto m=\dfrac{f}{f-u}$

$\\ \sf\longmapsto 3=\dfrac{20}{20-u}$

$\\ \sf\longmapsto 3(20-u)=20$

$\\ \sf\longmapsto 60-3u=20$

$\\ \sf\longmapsto 3u=40$

$\\ \sf\longmapsto u=13.3cm$

m=magnification
f is focal length
C is radius of curvature
u is object distance

Two blocks A and B have a weight of 11 lb and 6 lb, respectively. They are resting on the incline for which the coefficients of

Andreas93 [3]

Answer:

the block that starts moving first is block A , fr = 1.625 N , fr = 1.5 N

Explanation:

For this exercise we use Newton's second law, for which we take a reference system with the x axis parallel to the plane and the y axis perpendicular to the plane

X axis

fr- Wₓ = 0

fr = Wₓ

Axis y

N- $W_{y}$ = 0

N = W_{y}

Let's use trigonometry to find the components of the weight

sin θ = Wₓ / W

Cos θ = W_{y} / W

Wₓ = W sin θ

W_{y} = W cos θ

Wₓ = 11 sin θ

W_{y} = 11 cos θ

The equation for friction force is

fr = μ N

We substitute

μ (W cos θ) = W sin θ

μ = tan θ

We can see that the system began to move the angle.

θ = tan⁻¹ μ

So the angles are

Block A θ = tan⁻¹ 0.15

θ = 8.5º

Block B θ = tan⁻¹ 0.26

θ = 14.6º

So the block that starts moving first is block A

The friction force is

Block A

fr = Wx = W sin θ

fr = 11 sin 8.5

fr = 1.625 N

Block B

fr = 6 sin 14.6

fr = 1.5 N

A coil consists of 180 turns of wire. Each turn is a square of side d=30 cm, and a uniform magnetic field directed perpendicular

alexira [117]

Answer:

Emf induced i equal to 329.4 volt

Explanation:

Note : Here i think we have to find emf induced in the coil

Number of turns in the coil N= 180

Sides of square d = 30 cm = 0.3 m

So area of the square $A=0.3\times 0.3=0.09m^2$
