Answer:
Explanation:
In the calculation of distance we do not take into account the direction of movement .So only magnitude of movement is taken care of.
On the other hand , in respect of displacement , we take into account even direction of movement along with magnitude.
Distance covered by flea = 45 - 27 = 18 cm
Displacement by flea = 27 - 45 = - 18 cm
Speed = Distance covered / time
= 18 / 3 = 6 cm / s
Velocity = - 18 / 3 = - 6 cm /s.
It us 200 energy if it the right awnser
<h3>Question 1</h3>
Answer
option C) velocity
Explanation
acceleration = Δv ÷ Δt
<h3>Question 2</h3>
Answer
option C) m/s²
Explanation
Δv ÷ Δt
= m/s ÷ s
= m/s x 1/s
= m/s²
<h3>Question 3</h3>
Answer
option B) velocity has both direction and speed.
That is why velocity can be negative but speed can not and velocity is rate of change of displacement where as speed is rate of change of distance.
