Answer:
Go to K.han Academy and look up High School Physics on there. Other than that You.Tube has some physics curriculums which probably have practice questions. If not you could just pause the video and see if you can answer the questions they're going over yourself. Also, searching up "Physics Worksheet" and such may help.
Answer:
False.....................................
The mass of the skydiver is 122.2 kg
Explanation:
We can solve the problem by using the concept of weight.
The weight of a body is the force of gravity acting on the body; near the Earth's surface, its magnitude is given by
where
m is the mass of the body
is the acceleration of gravity
In this problem, we know the weight of the skydiver:
W = 1198 N
So we can re-arrange the equation to find its mass:

Answer:
B. 6.6%
Explanation:
The percentage error of a measurement can be calculated using the formula;
Percent error = (experimental value - accepted value / accepted value) × 100
In this question, the calibrated 250.0 gram mass is the accepted value while the weighed mass of 266.5 g is the experimental or measured value.
Hence, the percentage error can be calculated thus;
Percent error = (266.5-250.0/250.0) × 100
Percent error = 16.5/250 × 100
Percent error = 0.066 × 100
Percent error = 6.6%
