‘velocity’ refers to how fast an object is moving ‘in a particular direction’. speed is only how fast something is moving and velocity is how fast something is moving AND the direction. (hope this helps)
Answer:
No more information is needed
Explanation:
Radio waves are electromagnetic energy, lower frequency forms of this type of energy that includes light and cosmic rays on the high frequency end that we are able to detect. So in free space (vacuum), radio waves travel at their fastest velocity, the “speed of light”. The reason for the quotation marks is because when light or radio waves are propagating through matter, we observe them traveling more slowly.
This would actually represents how the distance expands over the period of time. So, when this shows us that, this person or this thing went 25 miles in 4 hours, this would show us the acceleration of this car and he speed that this car or object would contain.
Answer: The correct answer is Option d.
Explanation:
Formula for Hooke's Law states that:
where, F = Force applied = 2N
k = spring constant = 4 N/cm
x = displacement of the spring from equilibrium position = ? cm
Putting values in above equation, we calculate the displacement or distance of the spring, we get:
Hence, the correct option is Option d.
