If any distances xi and xf with their corresponding time intervals ti and tf are given we use the formula

Where xi = Initial Distance,

xf = Final distance,

ti = Initial time,

tf= Final time.

If Initial velocity U and final Velocity V are given, we use the formula

Where,

U = Initial Velocity

V = Final Velocity.

The volume of water displaced in the beaker is equal to the volume of the submerged part of the can.

**Answer:**

the principle of conservation of energy cannot be violated.

the correct one is: The total power is equal to the sum of the powers dissipated by the resistors.

**Explanation:**

The power in an electric circuit is given by

P == I V

In a circuit with several components (resistors) the power dissipated is the current by the voltage in each resistance, by the principle of conservation of energy the current in each resistance is the same if the circuit is in series and the current is the same if The circuit is in parallel, but cannot be greater than the current supplied by the power source.

Therefore, the power dissipated by the entire circuit is the sum of the power dissipated by each part, since the principle of conservation of energy cannot be violated.

When reviewing the answers, the correct one is: The total power is equal to the sum of the powers dissipated by the resistors.

The **acceleration **of the cart is **low **with the low fan speed because **acceleration **depends on **speed**.

<h3>What was the acceleration of the cart with the low fan speed?</h3>

The **acceleration **of the cart with the low fan speed is also **lower **because acceleration depends on the **velocity **or speed of an object. If **speed **is lower, the **body **moves very slow and the **acceleration **is also low and vice versa.

So we can **conclude **that the **acceleration **of the cart is **low **with the low fan speed because **acceleration **depends on **speed**.
