Answer:
Divide the change in velocity by the time interval
Explanation:
Acceleration is defined as the rate of change of velocity.
mathematically it is the change in velocity divided by the time taken for that change.
i.e Divide the change in velocity by the time interval.
Answer:
Explanation:
Assuming the light takes essentially no time to reach you, the distance at which the lightning occurred can be calculated by multiplying the speed of sound by the time it takes to hear the thunder:
Answer:
8.36e2
Explanation:
Use a scientific calculator
Since the man and the walkway has velocity (which is a vector) moving in the same direction, who would add the velocities together.
That means the relative velocity would be 2 m/s to the East
If you picture it in your mind, imagine walking down an escalator, you feel like you're moving faster than you really are.
In a different example, if the man was moving 0.9 m/s to the West, they are moving in opposite directions, which means you would subtract the 2 velocities.
Answer:
25 cm²
Explanation:
Meters and centimeters are both the units for measuring length. The SI unit of measuring length is meters.
Area is the quantity which measures the cross-section occupied by the object.
Thus,
Given that = Area = 0.0025 m²
To convert into cm²
1 m = 100 cm
So, 1 m² = 10000 cm²
So,
<u>Area = 0.0025 × 10000 cm² = 25 cm²</u>
