A team of engineers is designing a car seat to hold a small child. They decide that the straps should be only 38 mm wide. Why do the straps in the car seat not need to be 47 mm wide?

45 is the correct answer

Iwould have to say sorry i can't elaborate more. hope this though!

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.

The force is push or pull
