Answer:
With distance from the ridge crest, the sediments and crust get thicker. This also supports the idea that the youngest rocks are on the ridge axis and that the rocks get older with distance away from the ridge (Figure below). Something causes the seafloor to be created at the ridge crest.
Answer:A
Explanation:
A positively charged glass rod attracts object x. So, object x must be negatively charged or uncharged.
This occurs because opposite charges attract each other or either object x is uncharged and a negative charge is induced in it as glass rod approach the object x.
So option A is correct
Answer:
D) 30.6J
Explanation:
Because:
gravitational potential energy=mass×gravitational field strength×height
1.3kg×9.8m/2squared×2.4m
= 30.6J
The appropriate expression for the calculation of power by relating the angular energy in a given time.
In other words the instantaneous power of an angular accelerating body is the torque times the angular velocity
Where
Torque
Angular speed
Our values are given by
The angular velocity must be transformed into radians per second then
Replacing,
The average power delivered by the engine at this rotation rate is 211.1kW
