Answer:
1.03
Explanation:
0.02 has two significant decimal figures, so start by shortening 1.0090 to 2 decimal places (3 significant figures). Round up the decimal to become 1.1 and add .02 to get 1.3.
False.
It is important to know what is around you when making decisions
Answer:
A) 0.44 rad/s
B) 3.091 rad/s
Explanation:
Initial angular momentum must be equal to final angular momentum.
W1 = 0.80 rad/s
I = 1360 kgm^2
Initial moment Iw = 0.8 x 1360 = 1088 rad-kg-m^2/s
For second case
I = (65 x 4)4.2 + 1360 = 2452 kg-m2-rad/s
New momentum = 2452 x W2
Where w2 = final angular momentum
= 2452W2
Equating both moment,
1088 = 2452W2
W2 = 0.44 rad/s0
If they were on it before,
Initial momentum
I = 1360 - (60 x 4)4.2
= 352 rad-kg-m^2/s
352W1 = 1088
W1 = 3.091 rad/s
<span>Letter
C has the correct illustration. Two objects with the same charge (in this case,
both are positively charged) will repel each other. </span>
Letter
A is incorrect because a positive charged object will attract a negatively
charged object.
Letter
B is incorrect because both of them are negatively charged, which means they
should be repelling each other.
