The <u>speed</u> of the ride is
Speed = (distance covered) / (time to cover the distance)
Speed = (4,000 m) / (45 min)
Speed = <em>88.89 m/s</em>
Speed = <em>1.481 m/s</em>
Speed = <em>5.333 km/hr</em>
There's not enough information given in the question to calculate the velocity of the ride. For example ...
-- If the ride was completely in a straight line, then the velocity would be exactly equal to the speed.
-- If the rider went 2km from his house and then 2km back home again, his velocity for the whole ride would be zero.
We just don't know from the information given.
The material can transmit heat by energy transfer through collision of atoms. The elements that has a high ability of transmitting heat within their material are the metals. They are said to have high thermal conductivity. As the metal heats up, because the atoms are closely packed, they easily transfer heat through conduction. For example, copper is used in electrical wirings because it has a high thermal conductivity.
Answer:
Each layer has its own properties, composition, and characteristics that affects many of the key processes of our planet. They are, in order from the exterior to the interior – the crust, the mantle, the outer core, and the inner core.
Explanation:
Answer:
6.32 m/s
Explanation:
KE = 1/2 m v^2
sqrt (2 * KE /m) = v = 6.32 m/s
