Answer: Earthquakes and Volcanic eruptions
Explanation:
You did not attach a picture however, this should be the correct answer.
Mid-oceanic ridge plate boundaries such as the Mid-Atlantic Ridge form as a result of plate separating at the boundary. This leads to earthquakes due to the forces of tension acting on the plates.
When this happens, the mantle is exposed and therefore there will be volcanic eruptions as the lava comes to the surface as magma. When this magma cools it creates new seafloors and underwater mountains.
Average speed of the first car= 15 miles/hr
Average speed of the second car= 30 miles/hr
Explanations:
distance= d= 90 miles
Time= 2 hrs
let speed of first cyclist= v
speed of second cyclist= 2v
relative speed = v + 2v= 3v
using relative speed= Total distance/Total time
3v= 90/2
3 v=45
v=15 miles/hr
so speed of first cyclist= 15 miles/hr
speed of second cyclist= 2 (15)= 30 miles/hr
Answer:
stronger forces between particles means the substance boils at a higher temperature.
Explanation:
A.pex
Answer: r^-1
Explanation:
V = (k × Q) / r, where V is electric potential, k is constant and r is distance from charge.
Since Q will not change, it can be considered a constant too.
So, we can write V ∝ 1/r
which is same as V ∝ r^-1
Answer:
0.3257 seconds
39.67 m/s
Explanation:
Speed = 263 km/h
Converting to m/s
Distance to travel = 23.8 m
Time = Distance / Speed
The time taken to go from one end of the court to the other is 0.3257 seconds
Time = 0.6 s
Speed = Distance / Time
The speed of the tennis ball is 39.67 m/s
