A metal sphere of radius 10 cm carries a charge of 2.0 MicroCoulomb.What is the magnitude of the electric field 5.0 cm from the sphere's surface?

Answer:

300 m.

Explanation:

From the question given above, the following data were obtained:

Initial velocity (u) = 15 m/s

Final velocity (v) = 25 m/s

Time (t) = 15 secs

Distance (s) =?

The distance travelled by the motorbike can be obtained as follow:

s = (u + v)t / 2

s = (15 + 25) × 15 / 2

s = 40 × 15 / 2

s = 600 / 2

s = 300 m

Thus, the distance travelled by the motorbike is 300 m.

Answer:

La velocidad del sistema bala-bloque es 5 metros por segundo.

Explanation:

El enunciado tiene una omisión gramatical. La forma correcta es la siguiente:

Una bala de 0.8 kilogramos de masa se mueve horizontalmente con una velocidad de 30 metros por segundo y se introduce en un bloque de 4 kilogramos, inicialmente en reposo. ¿Cuál es la velocidad de la bala y el bloque después del impacto?

Esta situación es un caso clásico de colisión enteramente inelástica, en donde el sistema bala-bloque no tiene influencia de fuerzas externas, entonces la situación queda descrita por la siguiente ecuación:

[tex]m_{b}\cdot v_{b,o} = (m_{b}+m_{B})\cdot v[/tex] (1)

Donde:

[tex]m_{b}[/tex] - Masa de la bala, en kilogramos.

[tex]v_{b,o}[/tex] - Velocidad inicial de la bala, en metros por segundo.

[tex]m_{B}[/tex] - Masa del bloque, en kilogramos.

[tex]v[/tex] - Velocidad del sistema bala-bloque, en metros por segundo.

Si sabemos que [tex]v_{b,o} = 30\,\frac{m}{s}[/tex], [tex]m_{b} = 0.8\,kg[/tex] y [tex]m_{B} = 4\,kg[/tex], entonces la velocidad del sistema masa-bloque es:

[tex]v = \frac{m_{b}}{m_{b}+m_{B}}\cdot v_{b,o}[/tex]

[tex]v = 5\,\frac{m}{s}[/tex]

La velocidad del sistema bala-bloque es 5 metros por segundo.

Answer:

428 Newtons

Explanation:

Weight = Mass * Acceleration (due to gravity)

42.8 × 10 =428 N

Explanation:

[tex]weight = mass \times gravitational \: field \: strength[/tex]

gravitational field strength on earth is 9.81m/s²

so weight = 42.8 * 9.81

Answer:

Shear Modulus = 2500 Pa = 2.5 KPa

Explanation:

The shear modulus is defined as the ratio between the shear stress and the shear strain. Hence, the shear modulus, in this case, can be calculated by the use of the following formula:

[tex]Shear\ Modulus = \frac{Shear\ Stress}{Shear\ Strain}\\[/tex]

we have,

shear stress = 20 N/m²

shear strain = 0.008

Therefore,

[tex]Shear\ Modulus = \frac{20\ N/m^2}{0.008}\\\\[/tex]

Shear Modulus = 2500 Pa = 2.5 KPa

Answer:

1. 5 V

2. A₂ = 1.2 A

Explanation:

1. Determination of the voltage measured at R₃.

Voltage at R₁ (V₁) = 1 V

Voltage at R₂ (V₂) = 6 V

Total voltage (Vₜ) = 12 V

Voltage at R₃ (V₃) =.?

Vₜ = V₁ + V₂ + V₃

12 = 1 + 6 + V₃

12 = 7 + V₃

Collect like terms

12 – 7 = V₃

V₃ = 5 V

Thus, the voltage measured at R₃ is 5 V

2. Determination of A₂.

From the circuit diagram, we can see that the resistors are in series arrangement. This means that the same current will pass through each resistor.

Thus,

A₂ = A₁ = 1.2 A

Answer:

the angular speed of the stone at the moment of release is 15.05 rad/s

Explanation:

Given the data in the question;

The point of release ( height ) h = 25.6 m

the time of the fall of the stone will be;

⇒√( 2h/g )

we know that g = 9.81 m/s

so we substitute

t = √( (2 × 25.6 m) / 9.81 m/s )

t = √( 51.2 / 9.81 m/s )

t = √( 5.219164 s )

t = 2.285 s

Now, let v represent velocity at the time of release

them v × t ~ v × 2.285 s is the horizontal distance traveled.

Given that; The horizontal distance of point X from the base of the cliff (directly beneath the point of release) is 34.4 times the radius of the circle.

so

v × 2.285 = 34.4 × radius

Now, if the angular speed is ω then velocity at the time of release will be;

v = radius × ω

hence;

(radius × ω)  × 2.285 = 34.4 × radius

radius cancels each other out and we have;

ω  × 2.285 = 34.4

ω = 34.4 / 2.285

ω = 15.05 rad/s

Therefore, the angular speed of the stone at the moment of release is 15.05 rad/s

The spring constant for a spring is stretched 0.15 m and the force was 1500 N is 10000.

The spring constant, k, is a measure of the spring's stiffness. It varies depending on the spring and material. The greater the spring constant, the stiffer the spring and more difficult to stretch.

The letter k symbolizes the "spring constant," which is a number that tells us how "stiff" a spring is.

If k is large, it means that more force is required to stretch it a certain length than would be required to stretch a less stiff spring the same length.

We know that,

F = k(x)

Where k is the spring constant.

Here, it is given that:

F = 1500N

x = 0.15m

So,

1500 = k (0.15)

k (0.15) = 1500

k = 1500/0.15

k = 150000/15

k = 10000

Thus, the value of spring constant is 10000.

Answer:

Speed = 3 m/s

Explanation:

Given the following data;

Distance = 2700m

Time = 900 s

To find the speed;

Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.

Mathematically, speed is given by the formula;

[tex]Speed = \frac{distance}{time}[/tex]

Substituting into the equation, we have;

[tex]Speed = \frac{2700}{900}[/tex]

Speed = 3 m/s

Answer:

Time = 43.88 seconds

Explanation:

Given the following data;

Speed = 2.5 m/s

Distance = 109.7 m

To find the time it would take to run the length of a standard football field, we would use the following formula;

[tex]Speed = \frac{distance}{time}[/tex]

Making time the subject of formula, we have;

[tex]Time = \frac{distance}{speed}[/tex]

Substituting into the formula, we have;

[tex]Time = \frac{109.7}{2.5}[/tex]

Time = 43.88 seconds

Therefore, it would take a tiger beetle 43.88 seconds to run the length of a standard football.

An object with no net forces acting on it which is initially at rest will remain at rest. If it is moving, it will continue to move in a straight line with constant velocity. Forces are "pushes" or "pulls" on the object, and forces, like velocity and acceleration are vector quantities.

Answer:

3.04 m

Explanation:

The interference by diffraction of waves is noticeable only when the dimension of the opening through which the wave is passing through is comparable to the wavelength of the passing wave.

It is given that :

Distance between two speakers, d = 1.19 m

Speed of sound,  v = 340 m/s

The frequency is f = 1163 Hz

Distance the student walk along the line of the speaker, D = 12.5 m

We know the wavelength of the sound produced by the speakers is given by :

[tex]$\lambda=\frac{v}{f}$[/tex]

  [tex]$=\frac{340}{1163}$[/tex]

  = 0.29 m

Now the distance between the central maximum and the first maximum position is given by :

[tex]$y=\frac{\lambda D}{d}$[/tex]

  [tex]$=\frac{0.29 \times 12.5}{1.19}$[/tex]

 = 3.04 m
