What is meant by an objects acceleration?

a. distance covered in an amount of time

b. how fast an object is changing speed

c. force needed to change an objects motion

d. magnitude of a push or pull

If the magnitude of b⃗ increases while its direction remains unchanged, how will the magnetic flux through the coil change?

An object of mass 180 g initially at rest explodes into three pieces. One piece has mass 70 g and moves directly west at speed 14 m/s, and another piece has mass 50 g and moves directly south at speed 18 m/s.

How are frequency and period related to each other

Why do paradigms change over time

If a car is moving along the highway at a constant speed of 50 m/s, is there an unbalanced force acting on the car? How do you know? Explain using one of Newton's Laws.

If a sprinter has an average acceleration of 9.5 m/s2, how long does it take for the person to go from rest to 10 m/s

If the average velocity of a duck is zero in a given time interval, what can you say about the displacement of the duck for that interval?

How much power can I generate while lifting a mass for 30 seconds?

A car is idling at a stoplight. When the light turns green, the car takes 12 seconds to accelerate to 18.7 m/s. What is the average acceleration of the car? 0.64 m/s2 1.6 m/s2 -0.64 m/s2 -1.6 m/s2
