Answer: Both objects have charges of the same sign</h2>
When two electrically charged bodies come closer, appears a force that attracts or repels them, depending on the sign of the charges of this two bodies.
This is stated by Coulomb's Law:
"The electrostatic force between two point charges and is proportional to the product of the charges and inversely proportional to the square of the distance that separates them, and has the direction of the line that joins them"
Mathematically this law is written as:
Where is a proportionality constant.
Now, if and have the same sign charge (both positive or both negative), a repulsive force will act on these charges.
WITHOUT air resistance . . . like on the moon, or in a tank with all
the air removed from it . . . a feather, an orange, and a watermelon
will all fall at the same rate.
So will a piece of tissue, a mosquito, school bus, a rock, and a cruise
ship.
If you drop them all at the same time, then they will all hit the ground
at the same time.
Answer:
5
Explanation:
i prefer to use algebra so yeah
0.5(m/s)=0.1 m*f divide 0.5 and 0.1 by 0.1
5=f
Answer:
The average speed is 8.0 km/h
Explanation:
We use the data for the return journey to calculate the distance travelled using the constant velocity equation:
s = v t =6*4=24km
Note I didn't change any units so the answer comes out in kilometres.
Now use the distance and time taken to travel to Guam to find the average speed:
v=st=24/3=8.0km/h
