Differences among males and females
Out of the choices provided I would choose B, this is because A is wrong due to simple machines making our work easier and require less energy, C is wrong due to the work actually being done faster due to simple machines. Now D and B felt like they were both correct but D just doesn't make much since when you apply it to the topic of Simple machines so I found B.
Answer:
Data from a cross-sectional study or survey might need to incorporate weights or design effects in the analysis.The analysis plan should specify which variables are most
Explanation:
Force = (mass) x (acceleration)
Mass = (force) / (acceleration)
There was 150N of force in one direction and 100N of 'force' in
the other direction. The net force on the object was (150 - 100) = 50N .
Acceleration = (change in speed) / (time for the change)
= (10 m/s) / (5s) = 2 m/s²
Mass = (net force) / (acceleration) = (50 N) / (2 m/s²) = 25 kilograms
The electrical energy consumed in one year by using the light bulbs is 8,760 kWh.
The given parameters:
- Number of light bulbs = 10
- Power consumed by each bulb = 100 W
- Time of energy consumption, t = 1 year
<h3>What is electrical energy?</h3>
This is the electric power consumed or dissipated at a given period of time.
The electrical energy consumed in one year by using the light bulbs is calculated as
E = Pt
Thus, the electrical energy consumed in one year by using the light bulbs is 8,760 kWh.
