Answer:
D
Explanation:
Gravity is the force of attraction between two objects.
Each object creates a gravitational field in wich every other object is affected by it.
Answer:
Time taken = 8.25 second
Explanation:
Given:
Force = 4000 N
Force = ma
4,000 = (1100)(a)
Acceleration = 3.6363 m/s²
v = u + at
0 = 30 + (3.6363)t
Time taken = 8.25 second

Which term BEST describes the form of beryllium shown? Protons=4 Neutrons=5 Electrons=2
✓ Ion
Answer:
1) 3.9 %
2) 1,38 kg
3) 0.13 cubic meters
Explanation:
Part 1)
Calculated current = 0.180 amps
Measured current: 0.173 amps
percent error :
%
Part 2)
mass1 = 1,155 kg
mass2 = 0.22 kg
Addition; 1.155 + 0.22 = 1 375 kg which should be rounded to just two decimals according to the addition rules for uncertainties:
Answer : 1,38 kg
Part 3)
Volume = 0.885 x 0.20 x 0.75 cubic meters = 0.13275 cubic meters
Notice that the smallest number of significant figures among the set of dimension given is two. Therefore, our answer should be rounded to two significant figures. That is:
Volume = 0.13 cubic meters
