Answer 1

P=mg

P=`1 200*10=12 000 (H)=12 (кН)

Answer 2

Calculating the Weight of the Car

To determine the weight of the car in kilonewtons, we can use the following formula:

Weight (in newtons) = Mass (in kilograms) × Acceleration due to gravity (9.81 m/s²)

Given that the mass of the car is 1.2 tons, we need to convert this to kilograms before proceeding with the calculation.

Conversion from Tons to Kilograms

To convert tons to kilograms, we use the conversion factor: 1 ton = 1000 kilograms

So, the mass of the car in kilograms is: 1.2 tons × 1000 kilograms/ton = 1200 kilograms

Calculation of Weight in Newtons

Now, we can calculate the weight of the car in newtons using the formula: Weight (in newtons) = 1200 kilograms × 9.81 m/s² = 11772 newtons

Conversion from Newtons to Kilonewtons

Finally, to convert the weight from newtons to kilonewtons, we use the conversion factor: 1 kilonewton = 1000 newtons

So, the weight of the car in kilonewtons is: 11772 newtons ÷ 1000 newtons/kilonewton = 11.772 kilonewtons

Therefore, the weight of the car is 11.772 kilonewtons.
