Explanation:

The branch is possessing gravitational potential energy.

Answer:

plastic

Explanation:

because it is an insulator that it is a poor conductor of electricity.

There is no flow of electricity in the plastic, so the plastic has greater resistance.

A substance's ability to obstruct the flow of electrical current is referred to as resistance. It is symbolized by the capital letter R. The ohm, frequently written as a word and sometimes represented by the capital Greek letter omega, is the unit of resistance that is typically used.

A component's resistance is one ohm when a one-volt potential difference (voltage) is present. The current in a direct-current (DC) electrical circuit is inversely proportional to the resistance, while the supplied voltage is held constant. The current is cut in half when the resistance is doubled; when the resistance is cut in half, the current is increased by double.

Thus, plastic has greater resistance.

It then pauses before flying with an average velocity of 6.8 m/s east for 3.5 s to another branch.

Answer:

9 m/s

Explanation:

The seagull flew at a constant velocity for a total of 32 seconds.

One-quarter of 32 is:

[tex]\implies \dfrac{1}{4} \times 32=\dfrac{32}{4}=8\; \sf seconds[/tex]

Therefore, if the seagull flew 72 meters in one-quarter of 32 seconds, it flew 72 meters in 8 seconds.

[tex]\boxed{\sf Speed=\dfrac{Distance}{Time}}[/tex]

To find the velocity (speed) of the seagull, substitute the distance and time into the formula:

[tex]\implies \sf Velocity=\dfrac{72}{8}=9\; \sf m/s[/tex]

Simple machines that are widely used include the wheel and axle, pulley, inclined plane, screw, wedge and lever. While simple machines may magnify or reduce the forces that can be applied to them, they do not change the total amount of work needed to perform the overall task.

Answer: 33

Explanation:

12+3=15, so in 3 years time Ruto will be 15.

Because 15 is said to be 1/3 times his fathers present age (x), you can plug that into an equation.

15=1/3(x)

Then solve the equation.

(3)15=[1/3(x)]•3

45=x

His father is currently 45, so if you subtract 12 from that, you get 33.

Ruto’s father was 33 years old 12 years ago.

Answer:

Although the wave slows down, its frequency remains the same, due to the fact that its wavelength is shorter. When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases.

Answer:

When waves travel from one medium to another the frequency never changes.

Explanation:

As waves travel into the denser medium, they slow down and wavelength decreases. Part of the wave travels faster for longer causing the wave to turn. The wave is slower but the wavelength is shorter meaning frequency remains the same.

Answer:

Acceleration

Explanation:

Let me teach u a trick, most teachers loves to tell students to memorize what the slope means, and what does the area below the graph mean, and i think this is bs

So how u do it is this

Now it is a velocity vs time

Now to find the slope u would take

Velocity / time

Now what is the unit for velocity? m/s

What is the unit for time? s

Therefore since u know to find the slope u use

Velocity divide by time

So just take the unit of velocity divide the unit of time and see what unit u get

m/s ÷s

m/s x 1/s

= m/s^2

What unit is this?

This is the unit for acceleration

This trick works for every graph u see, and let me show u an extra bonus one

Now u are velocity vs time graph

Now if they ask u what does the area below graph means?

So u know area is just height x length, in other words y axis × x axis

So it means velocity x time

Therefore what would u get? Same trick

m/s x s

= m

What is m? m is meter, and this stands for displacement

For the student that walks to the right 25 m in 15 s and then turns and walks to the left 15 m in 8.0 s, we have:

1. The average speed is 1.74 m.

2. The average velocity is 1.42 m.

1. The average speed is an scalar wich is given by:

[tex] V = \frac{d_{t}}{t_{t}} [/tex]

Where:

[tex]d_{t}[/tex]: is the total distance

[tex]t_{t}[/tex]: is the total time

The total distance and the total time can be calculated as follows:

[tex]d_{t} = d_{1} + d_{2} = 25 m + 15 m = 40 m [/tex]

[tex] t_{t} = t_{1} + t_{2} = 15 s + 8.0 s = 23 s [/tex]

Since V is a scalar, the direction of motion is not important to calculate the final value.

Then, the average speed is:

[tex] V = \frac{d_{t}}{t_{t}} =\frac{40 m}{23 s} = 1.74 m/s [/tex]

2. The average velocity is a vector, so the direction of motion is important here. This ΔV can be calculated with the following equation:

[tex] \Delta V = \frac{\Delta x}{\Delta t} = \frac{x_{f} - x_{i}}{t_{f} - t_{i}} [/tex]

Where:

x: is the displacement  

f: is for final and i: is for initial

Hence, the average velocity is:

[tex] \Delta V = \frac{x_{f} - x_{i}}{t_{f} - t_{i}} = \frac{15 m - 25 m}{8.0 s - 15 s} = 1.42 m/s [/tex]

Answer:

Explanation:

if there is a fire there is no time to waist

The answer depends on depends on your age and your capacities:

If you are a child, the correct option is A.

If you are a scientist adult, the correct option is B.

I will assume that you are a child, so you shouldn't be in any danger. In a laboratory, we can find a lot of glass and flammable things, so it is really dangerous to be near a fire.

Then really easily we can conclude that the correct option is A, immediately notify your instructor (who should have the knowledge to handle the situation)

Never try to handle it by yourself, especially never throw water on the fire, as there are a lot of cases (like if some oil starts combusting) where throwing water will make the situation a lot worst.

Now, if you are an adult and you are instructed in how to handle lab hazards, you should know where the nearest fire extinguisher is, then you can run to get it and extinguish the fire before it goes out of control.

Answer:

The coil spring of a wind-up clock.

An archer's stretched bow.

Explanation:

The displacement of the mouse is 5m and the total distance is 9m.

The given parameters;

initial displacement of the mouse = 5 m north

second displacement = 1 m South

third displacement = 3 m west

To find:

Displacement is the change in the final position and the initial position of an object.

Distance is the total path covered by the object.

When the mouse was at 1 m south, the displacement = 5 m - 1m = 4m

The displacement of the mouse between 4m south and 3m west is calculated by using Pythagoras theorem.

[tex](displacement)^2 = 3^2 + 4^2\\\\(displacement)^2 = 25\\\\displacement = \sqrt{25} \\\\displacement = 5 \ m[/tex]

The total distance of the mouse = 5 m + 1m + 3m = 9m

Thus, the displacement of the mouse is 5m and the total distance is 9m.
