Answer:
Average speed, v = 11.37 m/s
Explanation:
Given that,
The distance covered by the traveler, d = 217 miles = 349228 meters
Time taken,
or t = 30708 s
We need to find the average speed for this trip. The average speed is given by :
v = 11.37 m/s
So, the average speed for this trip is 11.37 m/s. Hence, this is the required solution.
It means you need to put a lot of heat into it to raise its temperature by just one degree.
Turbine, rotational energy, and electric generators are the correct answer for the blanks from the given options.
<h3>What is an electric motor?</h3>
An electric motor is a mechanism that turns electricity into mechanical energy.
The interaction between the motor's magnetic field and electric current in a wire winding generates force in the form of torque imparted to the motor's shaft in most electric motors.
An electric generator is physically equivalent to an electric motor, but it converts mechanical energy into electrical energy using a reversed flow of power.
The sentences describe how power generation works as;
All <u>turbines </u>work on the same basic principle of converting kinetic energy, generated through the combustion of fuels or from the movement of wind or water, into <u>rotational energy.</u> This energy is then used to drive an <u>electric generator</u> to produce electricity.
Hence, Turbine, rotational energy, and electric generators are the correct answer for the blanks.

Q = mcθ
Where m = mass of water in kg.
c = specific heat capacity in kJ/kg⁰C, c for water = 4200 kJ/kg⁰C
θ = temperature rise in ⁰C
Q = 100*4200* 20 Note here the temperature rise is 20 ⁰C
Q = 8 400 000 J
In calories, 4.2 J = 1 Calorie
= 8 400 000 / 4.2 = 200 000
Q = 200 000 Calories
