Weight is a force and it can replace force in the equation. The acceleration would be gravity, which is an acceleration. Fw = 30 kg * 9.8 m/s^2 = 294 N. To change from weight to mass divide by gravity (9.8 m/s^2).
Answer:
I think its 4, like I'm 90%sure
The answer is right in front of your face lol
Answer:
There is an error in the fourth option, The correct option is:
High accuracy and good validity
Explanation:
The accuracy of a measurement refers to the closeness of the measurements to the true value of what is being measured while the validity of a measurement is the degree at which the measured value correlates with the true value. In other words, validity portrays how accurate a measurement is and vice versa.
If a series of measurements are very close to the true value i.e. HIGHLY ACCURATE, then the measurements is said to have a GOOD VALIDITY i.e. it measures what it claims to measure (true value). Therefore, a HIGH ACCURACY AND GOOD VALIDITY OCCUR TOGETHER IN A MEASUREMENT because how accurate a measurement is tells you how valid it is.
