what is the formula for impulse?
a impulse = σfδt b impulse = mv
c impulse = mgh d impulse = ma

Explanation:

To determine the formula for impulse, we recall the concept from physics (a subfield of Natural Science). Impulse is defined as the product of the average force (\(\sum F\)) applied to an object and the time interval (\(\Delta t\)) over which the force acts. Let's analyze each option:

• Option A: \(\text{Impulse} = \sum F\Delta t\) matches the definition of impulse.
• Option B: \(mv\) is the formula for momentum, not impulse.
• Option C: \(mgh\) is the formula for gravitational potential energy, not impulse.
• Option D: \(ma\) is the formula for force (from Newton's second law, \(F = ma\)), not impulse.

Answer:

A. Impulse = \(\sum F\Delta t\)
