Answer:
Always.
Unbalanced forces mean there will be an acceleration on the object, so speed will change no matter how fast its going already.
It hink that it is the 2nd one
Answer:
Our modern ideas about government were influenced by many different ideas and traditions. The biggest influence came from their British heritage. (Remember the colonists WERE British until the American Revolution!)
There's actually only one latitude implied by anything attached the question . . . Zero, since there are no choices listed.
That's brilliant ! Because zero latitude (the equator) IS the place on Earth where tangential speed is greatest.
Very clever !
In physical science, there are two types of quantities. The scalar quantity and the vector quantity. The scalar quantity has only the magnitude while the vector quantity has both the magnitude and direction. Displacement is the distance from the starting point to the end point of an object.
The distance traveled by an object can be calculated by the equation,
D = s x t
where D is the distance, s is the speed, and t is time.
Note to convert the given dimensions properly to be able to cancel units from numerator and denominator of the fraction.
D = (100 km/h)(7.5 min)(1 h/60 min) = 12.5 km
This means that the object was just back to the original point. Hence, the displacement is equal to ZERO.
