There exists the same question that has the following choices.
<span>1 the car's friction is reduced to zero
2 the car's centripetal force drops to zero
3 the car continues in a straight path from the point at which it encountered the ice
4 the car continues in a circular path from the point at which it encountered the ice
</span>
The correct answer is choice 3 <span>the car continues in a straight path from the point at which it encountered the ice</span>
Answer: 144 g
the mol of the oxygen gas is 64/16 = 4 (mol)
we have:
2H2 + O2 => 2H2O
4 ------> 8
=> the mol of H2O is 8 mol
=> m(H2O) = 8.(2 + 16) = 8.18 = 144 (g)
Explanation:
Answer:
Explanation:
length L = 5±.1
percentage error
= 0.1/5 x 100 = 2%
breadth b = 3.8 ±.1
percentage error
= .1 / 3.8 x 100
= 2.6 %
Maximum reading of length = 5.1 m
maximum reading of breadth = 3.9m
maximum area possible = 5.1 x 3.9
= 19.9 m².
maximum possible error in the measurement of area in percentage terms
= 2+2.6 = 4.6 %
error in maximum area
19.9 x 4.6 /100
= .9 m²
Minimum possible measurement of area
4.9 x 3.7 = 18.1 m²
possible error
18.1 x 4.6 / 100
= .8 m²
Answer:
.004 Hz
Explanation:
Frequeny is cycles per second. An oscillation is 1 cycle
F=cycles/sec
4/100
=0.004Hz (Hz- Hertz=1 cycle/sec)
