Answer:
when A and B are travelling opposite directions
Answer:
I'm pretty sure it's air pressure.
Explanation:
Answer: 54.55 m/s
Explanation:
Distance = 300 m
Time = 5.5 s
Average Speed = Total Distance/Total Time
= 300/5.5
= <u>54.55 m/s</u>
Hope this helped..
Answer:
The work done by the electric force is =
The potential of the starting point with respect to the end point is
The magnitude of E
Explanation:
Looking at this we can see that the work done by the electric force is equal to the kinetic energy this is because on the electric field is uniform and that the work done resulted in motion.
Mathematically
Where is the potential difference
q is the charge whose value i given as =
W is the workdone whose value is obtained as =
Substituting
Mathematically
Where E is the electric field strength
d is the distanced moved and it is given as 6.00 cm = 0.06 m
Making E the subject of the formula
Given :
An object with a volume of 9 cm³ is completely submerged in the water.
To Find :
How much water is displaced by the object.
Solution :
According to Archimedes' principle, the amount of volume displaced of fluid when an object is fully and partially submerged into that is equal to the volume of the object below the surface of liquid.
Now, it is given that object is fully submerged into water.
Therefore, volume of water displaced by the object is 9 cm³.
