A girl rides her scooter to school, a total distance of 4.5km. She has to slow down twice to cross busy streets, but overall the journey takes her 0.65h. What is her average speed during the trip?

Answers

Answer:

6.93 km/h

Explanation:

To calculate her average speed, we need the "speed" formula, which is:

average speed = distance / time

You plug in your numbers and it will give you the answer.

Speed = 4.5km/0.65hr

= 6.923 km/h

Using simple language, explain how your demonstration shows the effect of distance on electric forces. Use the terms electric charge, electric field, and electric force.

Answers

Explanation:

For a charge concentrated nearly at a point, the electric field is directly proportional to the amount of charge; it is inversely proportional to the square of the distance radially away from the centre of the source charge and depends also upon the nature of the medium.

The electrical forces that exist between two charged objects will be inversely related to the distance of separation that's between the objects.

Coulomb's law describes the electric force between charged objects. It should be noted that gravitational force and electric forces reduce with the square of the distance between the objects.

Every constituent of matter possesses an electric charge that can either be positive, negative or zero. In electrostatics, the electrical forces that exist between two charged objects will be inversely related to the distance of separation that's between the objects.

When the separation distance is increased, it'll lead to a reduction in the force of attraction between the objects.

Will the net force be greater or lesser for objects with greater mass?

Answers

The net force will be lesser for objects with greater mass

Answer:

The answer is

→ If an object has a greater mass, then the net force will be lesser.

Explanation:

The net force will be lesser because the greater mass the object is, the slower the net force will be.

If we were to talk about lesser mass in an object, then the net force will be faster, but this isn't the case right now.

D.they all ran the same speed

Answers

They run at the same speed hope this help can give me brainiest

They all ran same speed of 3mph, to find speed we do s=d/t we do distance divided by time 12 divided by 4 is 3, 30 divided by 10 is 3, 10 divided by 40 is 3, so they all ran the same speed

Answers

The Sun looks like it is traveling through the sky in the daytime from Earth and seems to vanish at night. This is because, to the east, the World revolves. The World revolves around its axis, an imaginary line between the north and south poles that stretches across the center of the Earth.

Why do we give shots in the neck and not anywhere else in pigs ?

Answers

Answer:The normal favored site in weaners, producers, finishers, and grown-ups is up to 70mm behind the base of the ear. Little piglets are regularly infused into the ham of the rear leg in light of the fact that there isn't a lot of muscle on the neck. This isn't suggested in producers/finishers in view of the chance of abscesses.

Explanation:

The common preferred site in weaners, growers, finishers and adults is up to 70mm behind the base of the ear. Small piglets are often injected into the ham of the hind leg because there is not much muscle on the neck. This is not recommended in growers/finishers because of the possibility of abscesses.

Do all types of light change materials in the same way

Answers

Transparent and translucent materials transmit most of the light that strikes them, but not all of it. Light can also
reflect off these materials. When light reflects, it is bouncing off something. Windows transmit most of the light that strikes them, but they also reflect light. If you have a lamp turned on near a window at night, you can see the reflection of the lamp in the window.
Transparent and translucent materials also absorb some of the light that strikes them. When something absorbs light, it is soaking up the light. When light is absorbed by an object, the light energy changes to heat energy and the object heats up. If you touch a window that has been in the sunlight, you will notice that it is warm.
Opaque materials do not transmit any light. All of the light that strikes an opaque material is reflected or absorbe

Light can be reflected, transmitted, or absorbed. You have read that EM waves can interact with a material medium in the same ways that mechanical waves do. Most things are visible because they reflect light. The two other forms of interaction are transmission and absorption.

Explain constant and changing velocity.

Answers

Answer:

To summarize, an object moving in a uniform circular motion is moving around the perimeter of the circle with a constant speed. While the speed of the object is constant, its velocity is changing. Velocity, being a vector, has a constant magnitude but a changing direction.

Answer:

In order for the velocity to be constant, the magnitude of the velocity (or speed) and the direction of the velocity must not change. Therefore, an object that travels with constant velocity covers the same distance during each time interval and moves in the same direction during the same time interval.
