Current and voltage are closely related properties of a circuit, one is caused by the other. What we refer to as voltage is in reality just a difference in charges, so, a difference in the amount o...

-They have a period of 24 hours -They lie above the equator A satellite in a polar orbit could be used for various things such as weather forecasting, GPS, to provide network services such as internet and...

An object will be stable if the centre of mass, the point at which all of the mass of the object is concentrated, is lower to the ground. It will also be stable if there is a wide base. Objects with low c...

Acceleration is defined as

A = change in velocity / time,

For this example

A = (34-25 )/ 6 = 9/6 = 1.5 m/s^2

By taking the formula F=m*a, and rearranging the make a the subject, we get a=F/m. Then by substituting in the values given we can work out that a=30/10=3. The units of acceleration are ms^-2 so...
