A 4.88 x 10-6 C charge moves 265 m/s

parallel (at 0°) to a magnetic field of

0.0579 T. What is the magnetic force

on the charge?

Answers

Answer:

[tex]F=0N[/tex]

Explanation:

From the question we are told that:

Charge [tex]Q=4.88 x 10-6 C[/tex]

Velocity [tex]v= 265m/s[/tex]

Angle [tex]\theta =0 \textdegree[/tex]

Magnetic field [tex]B=0.0579T[/tex]

Generally the equation for Force is mathematically given by

 [tex]F=Q(\=v*\=B)[/tex]

 [tex]F=qvBsin\theta[/tex]

Therefore

 [tex]F=qvBsin0 \textdegree[/tex]

 [tex]F=0N[/tex]

Answer:

0 newtons

Explanation:

When a moving charge is parallel to the magnetic field, it feels no Magnetic force at all.

Even if the Magnetic Field is 100,000,000 Tesla!

The formulas used to analyze the horizontal and vertical motion of projectiles launched at an angle invlove and use of which functions

Answers

Answer:

Explanation:

The formula to analyze motion in the vertical (or y) dimension is

[tex]A_y=Asin\theta[/tex] which says that the motion in the y-dimension is equal to the magnitude of the A vector times the sin of the angle.

The formula to analyze motion in the horizontal (or x) dimension is

[tex]A_x=Acos\theta[/tex] which says that the motion in the x-dimension is equal t the mignitude of the A vector times the cosine of the angle.

Many times this is used to find the upwards velocity and the horizontal velocity when an overall velocity is given with an angle of inclination.

One block rests upon a horizontal surface. A second identical block rests upon the first one. The coefficient of static friction between the blocks is the same as the coefficient of static friction between the lower block and the horizontal surface. A horizontal force is applied to the upper block, and its magnitude is slowly increased. When the force reaches 52.1 N, the upper block just begins to slide. The force is then removed from the upper block, and the blocks are returned to their original configuration. What is the magnitude of the horizontal force that should be applied to the lower block, so that it just begins to slide out from under the upper block

Answers

Answer:

F = 156.3 N

Explanation:

Let's start with the top block, apply Newton's second law

         F - fr = 0

         F = fr

         fr = 52.1 N

Now we can work  with the bottom block

In this case we have two friction forces, one between the two blocks and the other between the block and the surface. In the exercise, indicate that the two friction coefficients are equal

we apply Newton's second law

Y axis

        N - W₁ -W₂ = 0

        N = W₁ + W₂

as the two blocks are identical

        N = 2W

X axis

        F - fr₁ - fr₂ = 0

        F = fr₁ + fr₂

indicates that the lower block is moving below block 1, therefore the upper friction force is

          fr₁ = 52.1 N

          fr₁ = μ N

a

s the normal in the lower block of twice the friction force is

          fr₂ = μ 2N

          fr₂ = 2 μ N

          fr₂ = 2 fr₁

we substitute

          F = fr₁ + 2 fr₁

          F = 3 fr₁

          F = 3  52.1

          F = 156.3 N

Use the universal law of gravitation to solve the following problem.


Hint: mass of the Earth is = 5.97 x 1024 kg


A scientific satellite of mass 1300 kg orbits Earth 200 km above its surface. If Earth has a radius of 6378 km, what is the force of gravity acting on the scientific satellite?


a. Write out the formula for this problem.


b. Plug in the values from this problem into the formula.


c. Solve the problem, writing out each step.


d. Correct answer

Answers

Answer:

a.

[tex]F =G \cdot \dfrac{M \cdot m}{r^{2}}[/tex]

b.

[tex]F =6,378 \times 10^{-11} \times \dfrac{5.97 \times 10^{24} \times 1,300}{6,578^{2}}[/tex]

c.

[tex]F =6,378 \times 10^{-11} \times \dfrac{5.97 \times 10^{24} \times 1,300}{6,578^{2}} = \dfrac{9.519165 \times 10^{18}}{832117} \approx 1.144 \times 10^{13}[/tex]

d. 1.144 × 10¹³ N

Explanation:

The universal law of gravitation is presented as follows;

[tex]F =G \cdot \dfrac{M \cdot m}{r^{2}}[/tex]

The given mass of the scientific satellite, m = 1,300 kg

The height of the orbit of the satellite, r = 200 km above the Earth's surface

The length of the radius of the Earth, R = 6378 km

The mass of the Earth = 5.97 × 10²⁴ kg

a. The formula for the universal law of gravitation is presented as follows;

[tex]F =G \cdot \dfrac{M \cdot m}{r^{2}}[/tex]

Where;

M = The mass of the Earth = 5.97 × 10²⁴ kg

m = The mass of the satellite = 1,300 kg

r = The distance between the Earth and the satellite = R + r = 6,378 km + 200 km = 6,578 km

G = The Gravitational constant = 6.67430 × 10⁻¹¹ N·m²/kg²

b. Plugging in the values from the problem into the formula gives;

[tex]F =6,378 \times 10^{-11} \times \dfrac{5.97 \times 10^{24} \times 1,300}{6,578^{2}}[/tex]

c. Solving gives;

[tex]F =6,378 \times 10^{-11} \times \dfrac{5.97 \times 10^{24} \times 1,300}{6,578^{2}} = \dfrac{9.519165 \times 10^{18}}{832117} \approx 1.144 \times 10^{13}[/tex]

The force acting between the Earth and the satellite, F ≈ 1.144 × 10¹³ N

d. 1.144 × 10¹³ N

Explanation:

Según la ley de Charles; el volumen de una determinada masa de gas es directamente proporcional a su temperatura a presión constante.

A partir de los datos proporcionados;

V1 = 0,2 L

T1 = 100 ° C + 273 = 373 K

V2 =

T2 = 0 ° C + 273 = 273 K

V1 / T1 = V2 / T2

V1T2 = V2T1

V2 = V1T2 / T1

V2 = 0,2 × 273/373

V2 = 0,146 L

Answer:

The answer is "Option B and Option D"

Explanation:

Isopropyl alcohol has an air pressure of 22,39 units with such a water contact angle of 72,86 units.

The melting points of Isopropyl alcohol are higher than water because of the weaker forces between the previously studied.

The flatter meniscus is indeed the isopropyl ethanol so because forces between the particles are smaller.

Interpret the following graphs by answering the questions below.
a. The figure below shows the Standing waves
How many nodes and antinodes?

Answers

Answer:

Nodes = 5 and antinodes = 4

Explanation:

Nodes are the points of zero amplitude and appear to be fixed. On the other hand, antinodes are points on a stationary wave that oscillates with maximum amplitude.

In this given standing wave, there are 5 points where the amplitude is 0. So, there are 5 nodes. Also, there are 4 points where the amplitude is maximum.

So, there are 5 nodes and 4 antinodes.
