</span>According to the exercise principle of balance, a workout should address all components of fitness.
<span>NOT:
</span>b. focus on balance and coordination
<span>c. target specific areas for improvement </span>
<span>d. vary exercise activities over time</span>
Speed is how fast and object moves and velocity is a variable that tells you both speed and direction
Answer:
Stress = 4.67 * 10^-7 N/m²
Explanation:
Young's modulus of the material = Stress/Strain
Given
Young's modulus = 228 x 10^9 Pa
Stress = 106,483 Pa
Required
Strain
From the formula;
Strain = Stress/Young modulus
Strain = 106,483 /228 x 10^9
Stress = 4.67 * 10^-7 N/m²

Work is the force done to an object to bring about a displacement of the object.
when the block is being moved there are 2 forces acting on the block.
the force applied acts on the block in one direction bringing about its displacement in that direction. Theres another force called frictional force which acts against the movement of the block in the opposite direction to the direction in which the block is moving.
The resultant force acting on the block is ;
F = force applied - frictional force
frictional force - coefficient of friction *mg
mg - mass * gravitational acceleration
mg = 1 kg * 9.8 ms⁻²
= 9.8 N
frictional force = 0.5 * 9.8 N
= 4.9 N
resultant force = 20 N - 4.9 N
= 15.1 N
work done = force * distance moved
= 15.1 N * 3 m
= 45.3 J
