<span>The moon is smaller and more dense than the Earth, and has less extreme temperature changes. The statement presented is True. In terms of temperature, since there is no atmosphere on the moon, then it has less extreme temperature changes. The moon can reach 253 Fahrenheit in the day and -387 Fahrenheit at night.</span>
Answer:
the speed of the block when it reaches point B is 14 m/s
Explanation:
Given that:
mass of the block slides = 1.5 - kg
height = 10 m
Force constant = 200 N/m
distance of rough surface patch = 20 m
coefficient of kinetic friction = 0.15
In order to determine the speed of the block when it reaches point B.
We consider the equation for the energy conservation in the system which can be represented by:
v = 14 m/s
Thus; the speed of the block when it reaches point B is 14 m/s
B.riding on a ferris wheel
E.a satellite orbiting the Earth
Explanation:
A person riding on a ferris wheel and a satellite orbiting the earth both depicts circular motion.
Circular motion is the motion of a body about a fixed axis or center.
- The motion path of the body forms a circle around the center.
- In circular motion, the travel path is along a circle.
- An orbiting satellite traces out its orbit round the earth.
- At certain times, it passes through that point over and over again.
- This is similar to that of a ferris wheel
Other options gives other types of motion.
