Answer:

17.3 miles

Explanation:

The man's average velocity is 73.3 mph (miles per hour).

Average velocity is a measure of the rate of displacement of an object in a given direction. It is the total displacement of the object divided by the total time taken to cover that displacement. In other words, it is the distance an object travels divided by the time it takes to travel that distance. Average velocity is an important concept in physics, as it can provide insight into the motion of an object and the forces acting upon it. Average velocity can be calculated using the equation: velocity = displacement/time.

This can be calculated by dividing the distance (55 miles) by the time (0.75 hours). Mathematically, this can be expressed as:

velocity = (distance / time)

velocity = (55 miles / 0.75 hours)

velocity = 73.3 mph

An unmanned spacecraft leaves for Venus. The statements, The weight of the spacecraft keeps changing and The mass of the spacecraft remains the same. This 2 statements A and D are true.

A spaceship is a machine or vehicle built to travel through space. Spacecraft are a form of artificial satellite utilised for a wide range of tasks, such as communications, Earth observation, meteorology, navigation, space colonisation, planetary exploration, and freight and person transfer. All spacecraft, with the exception of single-stage-to-orbit vehicles, need a launch vehicle (carrier rocket) to get into space.

A spacecraft that is performing a sub-orbital spaceflight launches into space and then lands without gaining enough momentum or energy to complete a full orbit of the Earth. Spacecraft enter confined orbits around the Earth or other celestial bodies for orbital spaceflights. Only humans are carried on human spacecraft either as crew or guests from launch or while in orbit (space stations).

Answer:

Explanation:

the answer is C.)

The torque produced by a perpendicular force of 75 N at the end of a 0.2 m wrench is 15 Nm.

The force which causes the object to rotate about any axis is called torque. In math form, it is equivalent to the product of force and perpendicular distance.

Torque is a twisting or turning force that frequently results in rotation around an axis, which may be a fixed point or the center of mass. The ability of something rotating, such as a gear or a shaft, to overcome turning resistance is another way to think of torque.

Given:

The perpendicular force on the wrench, P = 75 N,

The length of the wrench, r = 0.2 m,

Calculate the torque of the wrench as shown below,

The torque of the wrench = r × P × sin a

Here, the force is perpendicular hence, a = 90°

The torque of the wrench = 0.2 × 75 × sin90

The torque of the wrench = 15 × 1

The torque of the wrench = 15

Thus, the torque on the wrench is 15 Nm.

Answer:

The wave diagramed in blue.

Explanation:

The reason for this is because frequency is explained as the number of times something has occurred in a certain period of time.

Here, we are talking about wavelength, so the frequency is the number of times the wave can oscillate in this time length.

Say we make dots on the middle of each downward slope. How long does it take to get to each dot compared to the other diagram? The answer is the one with the least amount of time. The wave diagramed in blue.

Answer:

Resistance of resistor A = 6.0 Ω and resistance of resistor B = 3.0 Ω

Explanation:

When the two resistors are in series, let V₁ = voltage in resistor A and R₁ = resistance of resistor A and V₂ = voltage in resistor B and R₂ = resistance of resistor B.

Given that V₁ + V₂ = 6.0 V and V₁ = 4.0 V,

V₂ = 6.0 V - V₁ = 6.0 V - 4.0 V = 2.0 V

Also, let the current in series be I.

So, V₁ = IR₁ and V₂ = IR₂

I = V₁/R₁ and I = V₂/R₂

equating both expressions, we have

V₁/R₁ = V₂/R₂

4.0 V/R₁ = 2.0 V/R₂

dividing through by 2.0 V, we have

2/R₁ = 1/R₂

taking the reciprocal, we have

R₂ = R₁/2

R₁ = 2R₂

From the parallel connection, let V₁ = voltage in resistor A and R₁ = resistance of resistor A and V₂ = voltage in resistor B and R₂ = resistance of resistor B. Since it is parallel, V₁ = V₂ = V = 6.0 V

Also, V₂ = I₂R₂ where I₂ = current in resistor B = 2.0 A and R₂ = resistance of resistor B

So, R₂ = V₂/I₂

= 6.0 V/2.0 A

= 3.0 Ω

R₁ = 2R₂

= 2(3.0 Ω)

= 6.0 Ω

So, resistance of resistor A = 6.0 Ω and resistance of resistor B = 3.0 Ω

The resistance of A is 6Ω while for B is 3Ω.

Potential difference is the amount of work done in moving a unit charge from one point to another.

When the two resistors are connected in parallel across the 6.0 V battery, the current in B is found to be 2.0 A, hence:

2 * Rb = 6 V

Rb = 3Ω

For the series connection:

I * 3 = (6 - 4)

I = 2/3 A

Hence:

(2/3) * Ra = 4

Ra = 6Ω

The resistance of A is 6Ω while for B is 3Ω.

The wavelength of the water wave is 0.75 meters.

Wavelength is the distance between successive peaks or troughs of a wave. It is denoted by the symbol λ (lambda) and is measured in meters (m) or other units of length.

The wavelength of a wave determines its properties such as its energy, frequency, and speed. In general, waves with longer wavelengths have lower frequencies and travel at slower speeds, while waves with shorter wavelengths have higher frequencies and travel at faster speeds.

Here in the Question,

The relationship between the wavelength (λ), frequency (f), and wave speed (v) of a wave is given by the equation:

v = λf

We are given the speed of the water wave (v) as 3.0 m/s and the frequency (f) as 4.0 Hz.

Plugging these values into the equation, we get:

3.0 m/s = λ x 4.0 Hz

Rearranging the equation to solve for the wavelength, we get:

λ = v/f = 3.0 m/s ÷ 4.0 Hz = 0.75 m

λ   = 0.75 m

Therefore, the wavelength of the water wave is 0.75 meters.

Answer:

The fraction of the weight of the astronaut on Callisto to the weight on Earth is 0.126.

Explanation:

From Newton's Law of Motion, the weight ([tex]W[/tex]), measured in newtons, of an object is defined by this expression:

[tex]W = m\cdot g[/tex] (1)

Where:

[tex]m[/tex] - Mass, measured in kilograms.

[tex]g[/tex] - Gravitational acceleration, measured in meters per square second.

The gravitational acceleration in Callisto is 1.236 meters per square second.

If we know that [tex]m = 50\,kg[/tex] and [tex]g = 1.236\,\frac{m}{s^{2}}[/tex], then the weight of the astronaut in Callisto is:

[tex]W = (50\,kg)\cdot \left(1.236\,\frac{m}{s^{2}} \right)[/tex]

[tex]W = 61.8\,N[/tex]

And the fraction is:

[tex]x = \frac{61.8\,N}{490\,N}[/tex]

[tex]x = 0.126[/tex]

The fraction of the weight of the astronaut on Callisto to the weight on Earth is 0.126.

Answer:

300 J

Explanation:

Height; h = 2.5 m

g = 10 m/s²

Thus;

mgh = 12 × 2.5 × 10 = 300 J

Since mgh = Kinetic Energy at bottom.

Complete Question:

Two identical soccer balls are rolled toward each other. What will be true after they collide headon?

Group of answer choices.

A. they will both stop rolling immediately after they collide head–on.

B. One ball will stop rolling and the other will roll backward at a slower speed.

C. They will both roll back at the same speed they had before the collision

D.They will both roll to the side at a faster speed after the collision

Answer:

C. They will both roll back at the same speed they had before the collision

Explanation:

Newton's Third Law of Motion which states that, for every action there is an equal but opposite reaction.

This ultimately implies that, in every interaction, there is a pair of forces acting on the two interacting objects.

In this scenario, two identical soccer balls are rolled toward each other. Thus, after they collide headon, they will both roll back at the same speed they had before the collision in accordance with Newton’s Third Law of Motion.

Additionally, The law of conservation of momentum states that the total linear momentum of any closed system would always remain constant with respect to time.

This ultimately implies that, if the two identical soccer balls exert forces only on each other, their total momentum is conserved
