Answer : The motion of the object is, non-uniform
Explanation :
Uniform motion : It is defined as the movement of an object along a straight line with constant speed. It travels equal distances in equal time interval.
The average speed of an object is similar to the actual speed of an object. The distance-time graph shows a straight line.
Non-uniform motion : It is defined as the movement of an object along a straight line with variable speed. It travels unequal distances in equal time interval.
The average speed of an object is different to the actual speed of an object. The distance-time graph shows a curved line.
The given graph B is a non-uniform motion graph.
Hence, the motion of the object is, non-uniform
A crystalline substance that contains water molecules is a ___. <em><u>hydrate</u></em>
Explanation:
A centripetal force (from Latin centrum, "center" and petere, "to seek") is a force that makes a body follow a curved path. (not sure but hope this helps )
Answer: 1.26kN
Explanation:
This kind of force that keeps a body moving in a circular path is known as the centripetal force (F). This force depends on the mass(m), velocity(v) and radius of the circular path in which the body moves (r).
Mathematically,
F = mv²/r
According to the question
Mass = 80.6kg
velocity = 3.34m/s
radius = 0.714m
F = 80.6×3.34²/0.714
F = 1259.3N
F = 1.26kN
Note that 1000N = 1kN
