According to the World Energy Council, the average household in Mexico consumes about 1600 kWh of energy per year. In Monterrey, Nuevo León, Mexico, the GHI Solar Map suggests that the average annual solar energy potential is about 1800 kWh/m2 per year. If solar panels are available in sizes of 1 m × 1 m with an efficiency of 17%, how many panels will be needed to power a house in Monterrey for a year?   Question 10 options:   6   7   2   1

You are renting a car to take a road trip from Ottawa to Halifax, about 1400 km. The car rental agency will allow you to choose either the gas or electric version of certain car model and the mileage fee is the same for both. If you choose the electric vehicle, you will need to do about 200 km extra driving since you need to stray from the main route to find electric charging stations. Assume the effective energy prices are constant at $0.108/MJ for gas and $0.063/MJ for electric. Further assume that the force due to rolling resistance is 260 N and the force due to air drag is 270 N. What total price in dollars will you pay for energy for each of the car types to overcome just these two forces while making this trip?   Question 31 options:   $15.12 for gas and $10.08 for electric   $80.14 for gas and $53.42 for electric   $40.82 for gas and $27.22 for electric   $80.14 for gas and $46.75 for electric

Question 51 of 55 How many tons of coal are needed per day to run a 1000 Mega Watt power plant? One Watt is 1 Joule / second. Joules are units of energy. When coal is burned it releases 21.5 Giga Joules per ton. Only about 45% of this energy is converted to electrical energy. 1 4 7 +/- 2 8 . 3 6 9 O Submit X x 100 +

A truck pulls a sled loaded with different kinds of vegetables at a certain distance. Suppose the sled with the load had an initial speed of v1 = 3.72 m/s and the total mass of the sled with the load is m = 1,619 kilograms. If the total work done on the sled with the load is Wtot = 18,488.6 joules, what is its final speed? Hint: Use work-energy theorem.

3. You run a washing machine (512 W) and an electric clothes dryer (5000 W) for 1.5 h each daily. (a) How much energy (in kW h) do the two appliances use in one day? (b) How much energy (in kW h) do they use in one year?

Calculate the number of kilowatt-hours (kW-hrs) consumed in a week by an 850- Watt window air conditioner that is left on all day. 20.4 kW-hrs 0.168 kW-hrs O 142.8 kW-hrs O 5.95 kW-hrs

A truck pulls a sled loaded with different kinds of vegetables at a certain distance. Suppose the sled with the load had an initial speed of v1 = 3.15 m/s and the total mass of the sled with the load ism = 1,621 kilograms. If the total work done on the sled with the load is Wtot = 21,497.6 joules, what is its final speed? Hint: Use work-energy theorem.

Do it quickly.

Use the following equations to solve. - A atom is subject to a force in N F(x)= -3x^3+4/x^2 How much work is done on the atom if it moves from x= 1.0 to x=5.0

A crate is being pushed across a rough floor surface. If no force is applied on the crate, the crate will slow down and come to a stop. If the crate of mass 50 kg moving at speed 8 m/s comes to rest in 10 seconds, what is the rate at which the frictional force on the crate takes energy away from the crate?
