Permanent magnet. An induced magnet would be created when a piece of iron (for example) is in contact with a magnet. Temporary magnets would be something like an electromagnet. Bar magnets are permanently magnetic unless we heat them or hammer them to cause their domains to loose alignment.

(ii) Calculate the force required to accelerate a mass of 60 kg at 2.5m/s2<br> force =<br> [2]
ikadub [295]

Answer:

Force = 150 Newton.

Explanation:

Given the following data;

Mass = 60kg

Acceleration = 2.5m/s²

To find the force;

Force = mass * acceleration

Force = 60 * 2.5

Force = 150 Newton.

Therefore, the force required to accelerate this mass is 150 Newton.

A particle moves along the x axis according to the equation x = 6t², where x is in meters and t is in seconds. Therefore:
vladimir2022 [97]
Answer is E

time can be negative.
A is not true because <span>a=<span><span><span>d2</span>x</span><span>d<span>t2</span></span></span>=12 m/<span>s2</span></span>
C: question already said that particle move along x-axis, which is not parabola path.
D: velocity is <span><span><span>dx</span><span>dt</span></span>=12t</span>, therefore velocity changes by 12 m/s and not 9.8 m/s
So we are left with E. <span>
