Answer:
gathered by using measurement tools and math
Explanation:
Quantitative data is often gathered by using measurement tools and math.
A quantitative data set is assigned values and numbers in order to solve a problem or for the purpose of a study.
- Each data set has a unique numerical value and can be counted.
- Qualitative data set does not use numerals and numbers.
- It engages the senses to make some scientific deductions.
- Examples are measurement of volume, distance, length, time, number of moles e.t.c
- Qualitative data sets include taste, smell, color e.t.c
Given,
Kinetic energy of the car = 2000 J
speed of the car is doubled
we know,
now, speed of the car is doubled
v' = 2 v
Using
=1/22
Hence, the Kinetic energy would be equal to 8000 J.
Answer:
The gravitational potential energy it had from being above the ground is converted to kinetic energy as the rock falls. As kinetic energy increases, the velocity of the rock will also increase.
Explanation:
The vertical velocity is affected by the acceleration of gravity (ignoring the effects of air resistance usually)
Answer:
A)
Explanation:
Energy transformation is when energy changes from one form to another.
