The figure shows a person's foot. In that figure, the Achilles tendon exerts a force of magnitude F = 800 N. What is the magnitude of the torque that this force produces about the ankle joint?

Iwill give 30 points to whoever answers ! what is the formula for actual mechanical advantage and ideal mechanical advantage?

What is special about a dc circuit ?

The protons in a nucleus are approximately 2 ✕ 10^−15 m apart. consider the case where the protons are a distance d = 1.93 ✕ 10^−15 m apart. calculate the magnitude of the electric force (in n) between two protons at this distance.
