**Answer:**

8 seconds

**Explanation:**

Since the carspeed is in km/h, we need equal units, so we will make 100.0m 0.1000km.

Then we need to find how long it takes the car to travel 0.1km

We can use the formula distance=speed * time and get

0.1=45 * time

Therefore we get .002222... hours

Multiplying this by 3600 (to get seconds, 60x60), we get 8 seconds

**Answer:**

C. It creates negative electric charges and pushes them into the circuit

**Explanation:**

A battery has three main parts. The Cathode (Positive), the Electrolytes (energy source), and the Anode (negative). The anode takes energy from the electrolytes and creates more electrons. And because subatomic particles with the same charge don't like being in the same place, they move through the circuit to reach the cathode because opposites attract.

I hope this helps!

**Answer:**

**Answer:**

Acceleration

**Explanation:**

We have given that the force by the motor

Resistive force by the water

So net force

Mass of the boat = 1384.1 kg

According to newton's second law F=Ma, here M is mass and a is acceleration

So

The temperature should be increased, causing the gas to expand and occupy more space.
