Answer:

30s

Explanation:

Q = charge in C(coulombs)

I = current in A(amps)

t = time in s(seconds)

Q = I × t

t = Q/I

Substitute in the given values.

t = 450C/15A = 30

t = 30s

Hope this helps! ^^

The heater was switched on for 30 seconds to allow 450 C of charge to flow through it.

To find the time the heater was switched on, we can use the equation Q = It,

where Q represents the total charge in coulombs, I is the current in amperes, and t is the time in seconds.

Given that the current (I) is 15 A and the total charge (Q) is 450 C, we can rearrange the equation to solve for time (t):

t = Q / I

Substitute the values:

t = 450 C / 15 A

t = 30 seconds

Therefore, the heater was switched on for 30 seconds to allow 450 C of charge to flow through it.

The car starts from rest, so \(v_i=0\), and we get

\({v_f}^2=2\left(2.8\dfrac{\rm m}{\mathrm s^2}\right)(69\,\mathrm m)\implies v_f\approx19.66\dfrac{\rm m}{\rm s}\)

A cylindrical pulley with a mass of 7.4 kg, radius of 0.702 m and moment of inertia 1 2 m r2 is used to lower a bucket with a mass of 1.6 kg into a well the linear acceleration of the falling bucket is 3.9174 m/s^2.

To find the linear acceleration of the falling bucket, we can use the equation for the motion of a falling object under the influence of gravity:

y = (1/2)gt^2

where y is the distance fallen, g is the acceleration due to gravity, and t is the time elapsed.

Since the bucket is attached to a pulley, its linear acceleration is related to the angular acceleration of the pulley, which can be found using the equation:

a = rα

where a is the linear acceleration of the bucket, r is the radius of the pulley, and α is the angular acceleration of the pulley.

The angular acceleration can be found using the equation:

τ = Iα

where τ is the torque applied to the pulley, and I is the moment of inertia of the pulley.

In this case, the torque is due to the weight of the bucket, so we have:

τ = mgy

where m is the mass of the bucket, g is the acceleration due to gravity, and y is the distance fallen.

Substituting in the given values, we have:

τ = (1.6 kg)(9.8 m/s^2)(0.702 m) = 10.9656 N·m

The moment of inertia of the pulley is given as 1/2mr^2, so we have:

I = (1/2)(7.4 kg)(0.702 m)^2 = 1.9663 kg·m^2

Using τ = Iα, we can solve for the angular acceleration:

α = τ/I = 10.9656 N·m / 1.9663 kg·m^2 = 5.5801 rad/s^2

Finally, we can use a = rα to find the linear acceleration of the bucket:

a = rα = (0.702 m)(5.5801 rad/s^2) = 3.9174 m/s^2

Temperature (°F) at 12 AM 99.1 98.8 99.2 97.1 97.4 97.8 97.2

Temperature (F) at 8 AM 99.3 98.8 97.6 97.7 97.1

Temperature (°F) at 12 AM 99.1 99.2 97.8 972 97.4

Let the temperature at 8 AM be the first sample, and the temperature at 12 AM be the second sample. Then,

d = x₂ - x₁

Now, we need to find the values of d for all five subjects.

Therefore, d is as follows:

d₁ = 99.3 - 99.1

   = 0.2

d₂ = 98.8 - 99.2

    = -0.4

d₃ = 97.6 - 97.8

d₄ = 97.7 - 97.2

   = 0.5

d₅ = 97.1 - 97.4

    = -0.3

In general, Hd represents the mean of all values of d.

Thus, the value of Hd is:

Hd = (0.2 + -0.4 + -0.2 + 0.5 + -0.3) / 5

Va and Vb are on opposite sides of the 6.24Ω resistor, so the potential difference across the resistor is negative. The circuit given in the figure below is a combination of parallel and series combinations of resistors and sources, which can be easily solved with the help of Kirchhoff's law and Ohm's law.

Solution:

First, let us label the points that are not known. Let Va be the voltage potential at point a, and Vb be the voltage potential at point b.

Voltage potential of point b:

Vb = ε2

Since the voltage source ε2 is directly connected to point b, the voltage potential of point b will be equal to the voltage provided by the source ε2 which is 9.27V.

Voltage potential of point a:

To find the voltage potential at point a, we first need to find the current through the 6.24Ω resistor (R2) since this resistor is connected between points a and b. To find the current flowing through the resistor R2 we need to use Ohm's law:

V = IR

IR = V/R2

Since the two branches are in parallel, the voltage across them will be the same as shown below:

Va - Vb = V1

V1 = i2R2

i2R2 = (ε2 - Va)R2/R1

i1 = (ε1 - Va)/[R1 + (R2R3/R1)]

Therefore, the potential difference between point a and point b is:

Va - Vb = 4.8218V - 9.27V

= -4.4482V

Va and Vb are on opposite sides of the 6.24Ω resistor, so the potential difference across the resistor is negative.

Therefore, the potential at point b is higher than the potential at point a.

The initial separation d between the mass and the spring is 0.14m.

A m = 2.88kg mass starts from rest and slides a distance d down a frictionless θ = 34.7° incline. While sliding, it comes into contact with an unstressed spring of negligible mass. The mass slides an additional 0.185m as it is brought momentarily to rest by compression of the spring (k = 409N/m).

The initial separation d between the mass and the spring can be calculated using the equation:

d = (2*m*g*sin(θ)) / k

Substituting in the given values, we get:

d = (2*2.88kg*9.8m/s2*sin(34.7°)) / 409N/m

Answer:

It reveals that light is a wave

Explanation:

Diffraction is the property of a wave in which there is a bending of the wave about the corners of an obstacle or aperture into the geometrical shadow of the obstacle or aperture.

This simply implies that a wave bends or spreads out when it passes through openings. Since the light diffracts through small slits and diffraction has been shown to occur in water waves and sound waves, this property of diffraction can only be characteristic of a wave and thus, this evidence reveals that light is a wave.

Answer:

It shows that light can travel in different wavelengths.

Explanation:

Light is similar to a wave in the way that it travels in a straight line, but when it is passing through the slits, it diffracts due to this difference. Therefore, light refracts in the same way as a wave would, and it is a mode of transferring energy. The light travels in a way similar to a wave

The magnitude of the force on the calcium ion is 1.0 x 10^7 N/C * e = 1.6 x 10^-19 N.

Magnitude is a measure of the size or strength of a physical quantity, such as size, brightness, or intensity. Magnitude can be measured in terms of intensity, size, brightness, or a combination of those criteria. For example, the magnitude of an earthquake is usually determined by measuring the intensity of the seismic waves that are generated by the earthquake. Magnitude is also used to measure the brightness of stars, with the brightest stars being given the highest magnitude.

The magnitude of the force on a calcium ion with charge +e is equal to the field strength multiplied by the charge of the ion. Thus, the magnitude of the force on the calcium ion is 1.0 x 10^7 N/C * e = 1.6 x 10^-19 N.
