Aluminium is ordinarily classified as a metal. It is lustrous, malleable and ductile, and has high electrical and thermal conductivity. Like most metals, it has a close-packed crystalline structure<span> and forms a cation in aqueous solution.</span>
Answer:
Quantity with direction and magnitude
Displacement
Explanation:
F = m * a = 60kg * 2 m/s^2 = 120 N
Answer:
s = 50.4 m
Hence, the point C is 50.4 m towards east from point B
Explanation:
Since, the motorcyclist travels at a constant speed in straight line towards east after point B. Therefore, we can use the following equation in this case:
s = vt
where,
s = distance covered = position of point C = ?
v = uniform speed of motorcyclist = 18 m/s
t = time interval = 2.8 s
Therefore,
s = (18 m/s)(2.8 s)
<u>s = 50.4 m</u>
<u>Hence, the point C is 50.4 m towards east from point B</u>
Velocity increases with speed
