Answer:
D. a heat engine that uses heat to do work
∆x (displacement) = v - u
where, v is the final position and u is the initial position.
Given, the final position of the object is 0 m and the initial position is 5 m.
∆x (displacement) = v - u
= 0 m - 5 m
= -5 m
Therefore, <u>C: -5m</u> is the correct answer.
Answer:
Explanation:
A )
The smallest tidal ranges are less than 1 m (3 feet). The highest tides, called spring tides, are formed when the earth, sun and moon are lined up in a row. This happens every two weeks during a new moon or full moon. Smaller tides, called neap tides, are formed when the earth, sun and moon form a right angle.
C ) The most extreme tidal range occurs during spring tides, when the gravitational forces of both the Moon and Sun are aligned (syzygy), reinforcing each other in the same direction (new moon) or in opposite directions (full moon).
Answer:
Acceleration, a = 750m/s²
Explanation:
Given the following data;
Radius, r = 0.31m
Velocity, v = 15m/s
To find the centripetal acceleration;
Substituting into the equation, we have;
Acceleration, a = 750m/s²
Therefore, the centripetal acceleration of the bike wheel is 750m/s².
Answer: A net force is the overall force on an object when all the individual forces acting on an object are added together. When there is a net force acting on an object, the force is said to be unbalanced. With balanced forces, equal forces are exerted in opposite directions providing a net force of zero
