Answer:
I think its C sorry if it's wrong
Oceanic crust is being formed it is because of the tectonic plates. Tectonic plates work because of volcanic eruption every time it will erupt the tectonic plates underground will have more pressure on magma, then below there will be a volcano thats why their is a volcano in ocean. The heat rises up then it will open, thats what we call divergent bounderies then their will be earthquakes form. Then another plate opens up and the crust is going down, it will stop if the volcano stops erupting because there is more lava left in volcano then it will go underwater and thats why oceanic crust is being formed.

Well, basically because the observations can help you out during the experiment.
Answer:
Explanation:
It is a case of oscillation by simple pendulum . Expression for simple pendulum is given as follows
T = 
where T is time period , l is length of pendulum and g is acceleration due to gravity .
, f is frequency of oscillation
For the given case

subsequently length becomes half so

dividing

f = 
frequency of oscillation becomes √2 times.
Answer:
3740N
Explanation:
The magnitude of the net force acting on an object is equal to the mass of the object multiplied by the acceleration of the object as shown in the formula below. If the net force acting on an object is zero, then the object is not accelerating and is in a state that we call equilibrium.
The formula for force is force = mass x acceleration.
To find mass, simply divide the force by the acceleration
acceleration=1.1m/s²
Mass=4500−760=3400N
Therefore, Mass x acceleration
=1.1m/s²x3400=3740N
