Neither set of choices is correct.
If the distance is tripled, then the forces decrease to
1/9 Fg. and. 1/9 Fe.
Note. When the objects are charged, the gravitational force Fg can almost always be ignored, since Fe is like 10^40 greater when the quantities of mass and charge are similar.
This question is probably referring to heat energy transferring from the car to its surroundings.
Answer:
For the first one c is the answer
For the second one c is also the answer
For the third one is b
Explanation:
I took that
The answer is C. friction, acting in opposition to the motion of the ball
Answer: position (x) and time (t)
Explanation:
A body is said to be in motion when its position changes with time with respect to a stationary observer.
Following are the types of motion:
<u>Uniform motion</u>: When equal amount of distance is covered in equal intervals of time.
<u>Non-Uniform motion</u>: When unequal amount of distance is covered in equal intervals of time.
Motion can be of the following types as well:
<u>Rectilinear motion</u>: when object moves in a straight line.
<u>Circular motion</u>: when object moves in a curved path.
<u>Periodic motion</u>: when motion repeats itself in fixed intervals of time.
Thus, in order to define motion, only two variables are required: position and time. Measuring these variables can determine whether the object is in motion or not and the type of motion.
