u knw dat u can help us pls

yea av got d formula. workdone=pressure*change in volume. therefore d ans is 6*10¤4J

Nope

Vcojuro: What is the causavative organism of salmonella typhi

Enterobacteria

Vcojuro:
1/2

d ans is -1/2

Influence01: What is d oxidation Number of oxygen in superoxide

-1/2

Influence01: d ans is -1/2

sorry i wrote d valence no

Vcojuro:
sorry i wrote d valence no

the valence number is 1/2 while d oxidatn no of O2 is -1/2

Kendzyma: 9.5

plz show ur workinz xo dat I can possibly point out ur mistake sire coz dats not d ans,...d ans is a whole no nt decimal no!

Sorry, I made a mistake in this Question 2. Here is the right question===
Question 2: If 8^x/2=2^3/8*4^3/4. Find x? Please that asterisk sign means multiplication sign.
Thanks in advance. Please show your workings.

Thanks in advance. Please show your workings.

d=10m r=5m
rate of delivery per sec =2ms-1
radius of pipe=20cm=20/100=0.2m
vol. Of hemisphere=2/3TTr^3
2/3*22/7*5^3
261.905cm3
note: since d rate of discharge by d pipe per second is 2, den height of d pipe =2m
vol. Of pipe used in dischargin water per sec=TTr2h=22/7*0.2^2*2
v=0.251m^3/s
Time to fill the tank in min =vol. Of pipe per sec * T =vol. Of hemisphere
wher T is d Time
0.251*T=261.905
T=261.905/0.251
T=1043.445/60=17.39
17.4 to 3s.f
2. 8^x/2=2^3/8*4^3/4
note,dat u av to find d index and power of each term of d terms if possible
so doing,we av 2^3(x/2)=2^3/8*2^2(3/4)
2^3x/2=2^3/8*2^3/2
accordin 2 d law of indices,x^y*x^z=x^y+z
so derefor,2^3x/2=2^(3/8+3/2)
lets find d Lcm of d exponents @ d right hand side
2^3x/2=2^(3+12)/8
2^3x/2=2^15/8
2 eliminates each oda since dey are dsame
and d eq bcomz 3x/2=15/8
cross multiply
x wil giv us 5/4
no 3,..wil take much of my tym bro,i gat to stop here!
