Answer:
8
Step-by-step explanation:
just do the comparation
Vb : Vs
b for big and s for small
4/3 π rb³ : 4/3 π rs³ (since there are 4/3 and π on both side, we can eliminate them so)
Vb : Vs = rb³ : rs³
Vb : Vs = (2rs)³ : rs³
Vb : Vs = 8rs³ : rs³ (delete the r³ on both side)
Vb : Vs = 8 : 1
so Vb is 8 times larger in volume than the small one
the right answer to the question is catch me on the root mean square velocity of gas molecule when measured by galvanometer to produce circular egg in the presence of light under blanket.
Cycled 480 meters but a<span>fter cycling 0.25 of the distance Wendy stopped and waited for Rick to catch up
0.25 (480) = 120 meters
</span><span>Wendy cycled at a speed of 80 meters per minute = 120 /80 = 1.5 minutes
</span><span>Rick's speed was 20 meters per minute slower than Wendy's = 120 / 60 = 2 minutes
so </span>2 minutes - 1.5 minutes = 0.5 minutes
answer
<span>Wendy waited 0.5 minutes for Rick </span>
Answer:
hello :
note : 1²+2²+3²+........+n² = n(n+1)(n+2)/6
Step-by-step explanation:
let : S = 1²+2²+3²+......+25²
A = 16²+17²+18²+...+25²
B = 1²+2²+3²+......+15²
S = (1²+2²+3²+....+15²) + (16²+17²+18²+...+25²)
calculate : S for : n = 25
S = 25(26)(27)/6 = 2925
calculate : B for : n = 15
B = 15(16)(17)/6 = 680
so : S = B + A
A = S - B = 2925 - 680 = 2245
