Answer:

Disagree

Explanation:

Concept of sink and float depends on the condition of water displaced by the objects

As we know that object will float when the weight of the object is less than the buoyancy force on it.

Also we can say that buoyancy force is the net upthrust applied by the water on the object.

This upthrust is equal to the weight of water that is displaced by the object.

So if heavy object displace more amount of water so that the weight of displaced water is more than the weight of the object then it must float on the water.

so this is not true that all heavy objects sink in water.

Disagree because its not about how heavy the object is and you don't know exactly how heavy, heavy is and the weight doesn't matter, its density that matters

What does it mean to say that science is a “systematic” process?
Maurinko [17]
Systematic is just a certain way of doing something. So science being systematic may just refer to the scientific method or how theories are proved in science by repeating the scientific method over and over again.

A parallel-plate capacitor is connected to a battery and becomes fully charged. The capacitor is then disconnected, and the sepa
AnnZ [28]

Answer:

Increases

Explanation:

The expression for the capacitance is as follows as;

C=\frac{\epsilon _{0}A}{d}

Here, C is the capacitance, \epsilon _{0} is the permittivity of free space, A is the area and d is the distance between the parallel plate capacitor.

It can be concluded from the above expression, the capacitance is inversely proportional to the distance. According to the given problem, the capacitor is disconnected from the battery and the distance between the plates is increased. Then, the capacitance of the given capacitor will decrease in this case.

The expression for the energy stored in the parallel plate capacitor is as follows;

E=\frac{Q^{2}}{2C}

Here, E is the energy stored in the capacitor, C is the capacitance and Q is the charge.

Energy stored in the given capacitor is inversely proportional to the capacitor. The charge on the capacitor is constant. In the given problem, as the distance between the parallel plates is being separated, the energy stored in this capacitor increases.

Therefore, the option (c) is correct.
