The percent error is by 12%
<span>The percent error is calculated by subracting the actual weight from the estimated weight and then dividing it by the actual value and multiplying it by 100% in absolute value(Which means to remove any negative sign) </span>
Answer:
Step-by-step explanation:
x² = 10² - 6² = 100 - 36 = 64
x = √64 = √8*8 = 8
Right angle triangle, use Pythagorean theorem
(hypotenuse)² = (adjacent)² + (opposite)²
Answer: D)600N
Step-by-step explanation:
The question is incomplete, since it is not given the acceleration. However, let's assume the truck's acceleration is
.
Now, according to Newton's second law of motion, the force
exerted on an object is directly proportional to its mass
and acceleration
:
![F=m.a](https://tex.z-dn.net/?f=F%3Dm.a)
Where:
![m=1200 kg](https://tex.z-dn.net/?f=m%3D1200%20kg)
![a=0.5 m/s^{2}](https://tex.z-dn.net/?f=a%3D0.5%20m%2Fs%5E%7B2%7D)
Solving the equation:
![F=(1200 kg)(0.5 m/s^{2})](https://tex.z-dn.net/?f=F%3D%281200%20kg%29%280.5%20m%2Fs%5E%7B2%7D%29)
Finally:
![F=600 N](https://tex.z-dn.net/?f=F%3D600%20N)
Answer:
- 1
Step-by-step explanation:
Multiplying a negative quantity by a negative quantity results in a positive.
Also multiplying by 1 leaves the other value as is, then
- 1 × -
= ![\frac{7}{11}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B11%7D)
½ means 1 divided by 2. ... You can divide the top and bottom of the fraction by 3 to get 1/2 . With fractions, you are allowed to multiply or divide the top and bottom of the fraction by some number, as long as you multiply (or divide) everything on the top and everything on the bottom by that number.
