Answer:

Earth: [tex]t = 498.667\,s[/tex], Mercury: [tex]t = 193\,s[/tex], Pluto: [tex]t = 19700\,s[/tex]

Explanation:

The light travels at a constant speed of approximately [tex]3\times 10^{8}[/tex] meters per second. The time ([tex]t[/tex]), in seconds, required for light to travel a given distance is:

[tex]t = \frac{x}{v_{l}}[/tex] (1)

Where:

[tex]x[/tex] - Travelled distance, in meters.

[tex]v_{l}[/tex] - Speed of light, in meters per second.

Now, we calculate the time for light to travel to each planet:

Earth ([tex]v_{l} = 3\times 10^{8}\,\frac{m}{s}[/tex], [tex]x = 1.496\times 10^{11}\,m[/tex])

[tex]t = \frac{x}{v_{l}}[/tex]

[tex]t = 498.667\,s[/tex]

Mercury ([tex]v_{l} = 3\times 10^{8}\,\frac{m}{s}[/tex], [tex]x = 5.79\times 10^{10}\,m[/tex])

[tex]t = \frac{x}{v_{l}}[/tex]

[tex]t = 193\,s[/tex]

Pluto ([tex]v_{l} = 3\times 10^{8}\,\frac{m}{s}[/tex], [tex]x = 5.91\times 10^{12}\,m[/tex])

[tex]t = \frac{x}{v_{l}}[/tex]

[tex]t = 19700\,s[/tex]

Answer:

An outside thermometer reads 57°F. What is this temperature in °C? Round your answer to the nearest whole number.

135

answer is A:14

Explanation:

The temperature of the thermometer which reads 57 °F in degree celsius (°C) to the nearest whole number is 14 °C

We can convert from degree celsius (°C) to degree Fahrenheit (°F) with the following equation

°C = 5/9(°F – 32)

°C = 5/9(°F – 32)

°C = 5/9(57 – 32)

°C = 5/9 × 25

°C = 14 °C

Thus, the temperature in degree celsius (°C) of the thermometer is 14 °C

Answer:

c.large amplitude waves have less matter than small amplitude waves

Answer & Explanation:

This can be explained with Newton's first law, Inertia - if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.  

When you walk, your entire body is in a forwarding motion. If your toe hits an object (in this case, a chair), only this unfortunate toe will stop while the rest of your body continues its forwarding motion, resulting in you falling forward.

Answer:

The torque is approximately 3.82 N·m

Explanation:

The relationship between work done, 'W', and the applied torque, 'τ' can be presented as follows;

W = τ × Δθ

Where;

W = The work done by the torque

τ = The magnitude of the torque

Δθ = The angle through which the object is turned

The parameters for 'W' and 'Δθ' are;

W = 3j

Δθ = 1/4 × π

From W = τ × Δθ, we have;

τ = W/Δθ

∴ τ = 3j/(1/4 × π) ≈ 3.81971863421 N·m

The torque, τ ≈ 3.82 N·m

Answer:

The resistor has a resistance of 10.667 ohms.

Explanation:

By Ohm's Law, voltage ([tex]V[/tex]), in volts, is directly proportional to the current ([tex]i[/tex]), in amperes, and by definition of power ([tex]\dot W[/tex]), in watts, we have the following formula:

[tex]\dot W = i^{2}\cdot R[/tex] (1)

Where [tex]R[/tex] is the resistance, in ohms.

If we know that [tex]\dot W = 24\,W[/tex] and [tex]i = 1.5\,A[/tex], then the resistance of the resistor is:

[tex]R = \frac{\dot W}{i^{2}}[/tex]

[tex]R = 10.667\,\Omega[/tex]

The resistor has a resistance of 10.667 ohms.

Explanation:

The net force when a force of 6N going left towards the object and the 8N going to the right towards the object ​is found to be 2N toward the right of an object.

Net force may be dfeined as the sum of all of the forces acting on an object. It is categorized as a vector quantity because it has both direction and magnitude to be considered.

Net force in a case where forces of different magnitude and opposite directions will be the difference between greater and lesser force. The combination of the resultant of all the forces acting on an object is called Net Force, which is basically the sum of all the forces acting on that object.

According to the question,

The force going towards the left of an object = 6N.

The force going towards the right of an object = 8N.

The net force = 8 - 6 = 2N towards the right of an object.

Therefore, the net force when a force of 6N going left towards the object and 8N going to the right towards the object ​is found to be 2N toward the right of an object.

Explanation:

Answer:

3 m/s²

Explanation:

Initial Velocity, u = 18

Final velocity, v = 36

Time, t = 6 seconds

Acceleration is the change in velocity of a body with time. It obtained using the relation :

Acceleration = (v - u) / t

Acceleration = (36 - 18) / 6

Acceleration = 18 / 6

Acceleration = 3m/s²

Hence, acceleration of the skier is 3m/s²
