Answer:

Sphere is a geometrical object in dimensional space that surface of a circle and ball.

Explanation:

Sphere is that the circular objects in the two dimensional space (1) circle

(2) disk. Two dimensional space is a set of points and the distance of that point,The two points of Sphere that length and center.

Sphere can constructed as the named of surface form circle about any diameter. circle is the special type of the revolution replacing the circle,

sphere is the distance r is the radius of the ball and circle is the center of mathematical ball,as the center and the radius of the sphere is to respectively.

The ball and sphere has not be maintained mathematical references as a solid references. A sphere of any radius is centered at the number of zero.

I will pick the branliest if answered these questions.

Bond [772]

n₁ = index of refraction of diamond = 2.4

n₂ = index of refraction of water = 1.33

θ₁ = angle of incidence = 24 deg

θ₂ = angle of refraction = ?

using snell's law

n₁ Sinθ₁ = n₂ Sinθ₂

inserting the values

(2.4) Sin24 = (1.33) Sinθ₂

θ₂ = 47.22 deg

c = specific heat = 4.18

m = mass of water = 3.5 kg

ΔT = change in temperature = 55 - 25 = 30 C

Q = heat taken

heat taken is given as

Q = m c ΔT

inserting the values

Q = (3.5) (4.18) (30)

Q = 439 J

n = number of moles = 1

m = molar mass = 0.0399 kg

T = temperature = 27 K

v = average velocity

average velocity is given as

v = sqrt(3RT/m)

v = sqrt(3 x 8.314 x 275/0.0399)

v = 414.6m/s

n = number of moles = 2

T = temperature = 35 C = 35 + 273 K = 308 K

U = internal energy

internal energy is given as

U = 2.5 n RT

U = 2.5 (2) (8.314) (308

U = 1.28 × 10⁴ J

F₁ = 3300 N

F₂ = ?

A₁ = 0.060 m²

A₂ = 0.18 m²

Using pascal's law

F₁/A₁ = F₂/A₂

3300/0.060 = F₂/0.18

F₂ = 9900 N

R = resistance of each resistance in series = 10 ohm

R' = equivalent resistance in series

equivalent resistance is given as

R' = 3 R

R' = 3 x 10

R' = 30 ohm

R = resistance of each resistance in parallel = 10 ohm

R'' = equivalent resistance in parallel

equivalent resistance is given as

R'' = R/3

R'' = 10/3

R'' = 3.3 ohm

for series circuit

R' = equivalent resistance in series = 30 ohm

V = Voltage applied = 60 Volts

i' = current in each resistor in series

current in each resistor in series is given as

I' = V/R'

i' = 60/30

i' = 2 A

for parallel circuit :

i = current in each resistor = V/R = 60/10 = 6 A

The three vectors in Fig. 3-33 have magnitudes a = 3.00 m, b = 4.00 m, and c = 10.0 m and angle θ = 30.0°. What are

aliya0001 [1]

Answer:

a) $a_{x} =3$ b) $a_{y} =0$

c) $b_{x} =3.46$ d) $b_{y} =2$

e) $c_{x} =0$ f) $c_{y} =10$

g) p = -5.77 h) q=5

Explanation:

Diagram for given question is attached below in fig 1

for vector $\vec{a}$

θ = 0°

$a_{x} = 3 cos (0)\\a_{x} = 3\\a_{y} = 3 sin (0)\\a_{y} = 0$

for vector $\vec{b}$

θ = 30°

$b_{x} = 4 cos (30)\\b_{x} = 3.46\\b_{y} = 4 sin (30)\\b_{y} = 2$

for vector $\vec{c}$

θ = 90°

$c_{x} = 10 cos (90)\\c_{x} = 0\\c_{y} = 10 sin (90)\\c_{y} = 10$

$\vec{c} = p\vec{a} + q\vec{b}$

$c =c_{x} \hat{i} + c_{y}\hat{j}\\as a_{y} =0\\c_{x} \hat{i} + c_{y}\hat{j} = pa_{x} \hat{i} +q(b_{x} \hat{i} +b_{y} \hat{j} )\\c_{x} \hat{i} = pa_{x} \hat{i} +qb_{x} \hat{i}\\c_{y}\hat{j} =qb_{y}\hat{j}$

$q=\frac{c_{y}}{b_{y}} \\q=\frac{10}{2}\\q=5$

$c_{x} \hat{i} = pa_{x} \hat{i} +qb_{x} \hat{i}\\0 = p(3) + (5)(3.46)\\p = -5.77$

Which of the following is the reason why the magnetic flux through the bracelet is changing?

charle [14.2K]

Answer:

a. The magnitude of the magnetic field is changing.

b. The magnetic field is changing direction with respect to the bracelet.

c. The bracelet is moving in the magnetic field.

Explanation:

Magnetic flux is a measure of the total magnetic field that passes through a given area. The value of the flux depends on the magnitude of the magnetic field, the area it crosses and its orientation relative to the magnetic field. Therefore, all three reasons are valid.

If forces acting on an object are unbalanced, which factors may result from an unbalanced force? Check all that apply. The net f

nordsb [41]

Answer: The net force is negative, The net force is positive, There is change in motion.

When an balanced force acts, there is change in motion. In case of balanced forces, the object does not change its motion. The unbalanced force causes change in the momentum of the object. There would be some net force. It would not be zero. The net force is zero when the acting forces are balanced. The net force in case of unbalanced forces have certain magnitude and are positive or negative depending on the direction. The positive and negative sign denotes direction of the net force.
