For this, you need the v-squared equation, which is v(final)² = v(initial)² + 2aΔx The averate acceleration is thus a = (v(final)² - v(initial)²) / 2Δx = (20² - 15²) / 2(50) = 175 / 100 = 1.75 m/s² So the average acceleration is 1.75 m/s²

When a wire within a closed circuit is coiled upon a nail, the nail will _______.
Natali5045456 [20]

when wire is coiled upon a nail then it will posses magnetic characteristics

This is due to the coiled shape it will behave like a solenoid and the magnetic field of solenoid is given as

B = \mu_o ni

so here when wire is coiled up on a nail then due to the magnetic field of the coil the nail will attain magnetic characteristic.

so correct answer will be

<em>Possess magnetic properties </em>

A baseball pitcher throws a baseball with a speed of 42 m/s . In throwing the baseball, the pitcher accelerates it through a dis
andrew-mc [135]

Answer:

a = 252 m / s²

Explanation:

The initial speed Vο = 0

The speed of baseball with witch it is thrown  Vf = 42 m/s

Displacement covered = 3.5 m

Hence acceleration will be constant at this moment, so as per the equation of constant acceleration : ( Vf² - Vο² ) / 2d = a

                                                            a = 252 m / s²
