A can opener makes work easier by increasing force.

Explanation

Technically a can opener is a simple lever that increases the force with which we remove the cap of the can. Levers are rod shaped objects with fulcrum at one end and the length of the lever has a positive impact on the force.

considering the equation

work=force*distance

indicates that increasing the length of the lever/can opener increases the work done by it.

Density = mass divided by volume so if you use that formula Liquid A turns out to be a higher density so it flows slower.

The** net force **that is applied to the passenger during the elevator **acceleration **is **218.75 N.**

<h3>What is net force?</h3>

This is the single **force **obtained from the combinatiion of two or more **forces**

To calculate the **net force** that is applied to the passenger during the elevator's acceleration, we use the formula below.

Formula:

- F = m(v-u)/t............ Equation 1

Where:

- F = force
- m = mass
- v = Final velocity
- u = initial velocity
- t = time.

From the question,

Given:

- m = 70 kg
- u = 0 m/s
- v = 12.5 m/s
- t = 4 s

Substitute these values into equation 1

Hence, The** net force **that is applied to the passenger during the elevator **acceleration **is **218.75 N.**

Answer:

I1 = ε/R1

I2 = ε/R2

I3 = ε/R3

Explanation:

From the image, we see that the resistors are connected in parallel. This means that the voltage passing through them is the same.

Now, formula for current is; I = V/R

In this case, V which is voltage is denoted by ε.

Thus;

I1 = ε/R1

I2 = ε/R2

I3 = ε/R3
