That’s the acceleration law! This would be a good example of inertia! When in a car, if the brakes are pressed immediately, the passengers will launch forward since their bodies are still in motion!
It’s the gravity pull of the sun that makes them spin around 360 degrees
It’s all so why they say In a billion years the sun will smash into the sun
-facts :)
Answer:
D
Explanation:
On an inclination of 30°, the acceleration down the inclination will be gsinФ. So the acceleration will be ⇒
g Sin30° = (0.50) g
The electric field due to a point charge of 20uC at a distance of 1 meter away from it is 180000 .
First, you have to know that the space surrounding a load suffers some kind of disturbance, since a load located in that space will suffer a force. The disturbance that this charge creates around it is called an electric field.
In other words, an electric field exists in a certain region of space if, when introducing a charge called witness charge or test charge, it undergoes the action of an electric force.
The electric field E created by the point charge q at any point P, located at a distance r, is defined as:
where K is the constant of Coulomb's law.
In this case, you know:
- K= 9×10⁹
- q= 20 uC=20×10⁻⁶ C
- r= 1 m
Replacing in the definition of electric field:
Solving:
<u><em>E=180000 </em></u><u><em /></u>
Finally, the electric field due to a point charge of 20uC at a distance of 1 meter away from it is 180000 .

Explanation:
As is showed at the figure annexed, we can solve this problem finding the relation between the girl displacement and the shadow displacement.
Relation the triangles (see figure annexed):
We derive in order to find the speed of the shadow, because:
dx/dt: shadow's speed
dy/dt: girl's speed
