Physics
1 answer:
borishaifa [10]4 years ago
5 0

Answer:

B

Explanation:

Potential difference has a SI Unit of Volt and its symbol is <em>V</em>. Hence answer is <u>B</u>.

A is wrong as it has the unit Joule <em>(J)</em> which is the SI unit for energy.

C is wrong as it has the unit Newton <em>(N)</em> which is the SI unit for force.

D is wrong as it has the unit Coulomb <em>(C)</em> which is the SI unit of charge.

Antonio has been told that he needs to work on his self- awareness. What might he do to most improve this skill
m_a_m_a [10]

For Antonio to improve his self-awareness skills he should be able to recognise hie strengths and his weaknesses.

<h3>What is self awareness?</h3>

Self awareness is the act of being able to recognise your feelings and keep your character under control.

To be a self awareness leader, one should be able to have the following qualities:

  • They should be able to recognize their strengths and challenges.
  • They should be able to recognise other people's needs and feelings,
  • They should be able to notice how their behaviour affects the people around them.

Therefore, it can be said for Antonio to improve his self awareness skills, he should be able to recognise his strength and weaknesses and observe how his character affects the people around him.

A 0.5 kg object, initially at rest, is pulled to the right along a frictionless horizontal surface by a constant horizontal forc
sergij07 [2.7K]

Answer:

A.) 12.5 J

B.) 12.5 J

C.) 7.1 m/s

Explanation:

Given that a 0.5 kg object, initially at rest, is pulled to the right along a frictionless horizontal surface by a constant horizontal force of 25 N for a distance of 0.5m.

a. What is the work done by the force?

Work done = force × distance

Work done = 25 × 0.5

Work done = 12.5 J

b. What is the change in the kinetic energy of the block?

Work done = energy

Change in Kinetic energy = work done

Change in kinetic energy = 12.5 J

c. What is the speed of the block after the force is removed?

Kinetic energy = 1/2mV^2

12.5 = 1/2 × 0.5 × V^2

25 = 0.5V^2

V^2 = 25/0.5

V^2 = 50

V = 7.1 m/s
