Calculate the weight of an object of mass 8.0 kg on Earth, where g = 9.8 N/kg.

A ball decelerates uniformly from 18 m/s to 0 m/s over a distance of 2.7 m while being caught. Using (final velocity)² = (initial velocity)² + 2 x acceleration x distance, calculate its deceleration.A ball decelerates uniformly from 18 m/s to 0 m/s over a distance of 2.7 m while being caught. Using (final velocity)^2 = (initial velocity)^2 + 2 x acceleration x distance, calculate its deceleration.

A resultant force of 60 N acts on a wheelbarrow of mass 15 kg. Calculate its acceleration.

A spanner is used to loosen a bolt. Explain why using a longer spanner makes it easier to loosen the bolt.

A radio wave has a wavelength of 3 m. Calculate its frequency, given that all electromagnetic waves travel at 3 x 10⁸ m/s in a vacuum.A radio wave has a wavelength of 3 m. Calculate its frequency, given that all electromagnetic waves travel at 3 x 10^8 m/s in a vacuum.
