If Max weighed 17.2 N on Ceres (gravitational field strength of 0.27 N/kg), then what would she weigh on Earth. Give your answer to 3 s.f. and state your units.

For this question you only need to know one equation, however, what is key is to be able to understand what the question is asking for and how to go about it.Weight is the force applied to a body due to the ...

A satellite is in orbit of the Earth, and moves at a constant orbital speed of 3055.5m/s. If it is at an altitude of 35786km, calculate the time period for a complete cycle, giving your answer in hours. Answer should be given in in 3 significant figures.

Orbital Speed = [2Π(Orbital Radius)]/Time Period 3055.5m/s = 10999.8km/h therefore: 10999.8km/h = [2Π(35786km)]/TT = [2Π(35786km)]/(10999.8km/h)T = 20.4 hours

Initially, trucks A and B are travelling in opposite directions. A has mass 1000 kg and is travelling at speed 7ms^-1. B has mass 4000kg and is travelling at speed 2ms^-1. What is their speed and direction after collision if they move together?

The law of conservation of momentum states that for a system, under the influence of no external forces, the sum of the momenta of all objects, which are calculated by multiplying their masses and velocities...

What is the difference between nuclear fusion and nuclear fission?

Both the processes of nuclear fusion and fission are dictated by the concept of a 'binding energy'. In basic terms, this is the energy required to separate an atomic nucleus into is constituent nucleons, i.e...

Describe the process of a capacitor charging.

At first, there is a potential difference between the two plates of the capacitor equal to the potential difference between the two battery terminals. This causes electrons to build up on one of the plates m...
