The density of blood as given in question = 1050 kg/m^3
Now
1 kg = 1000 gm
So
1050 kg = 1000 * 1050 gm
= 1050000 gm.
1 m = 100 cm
Then
1 m^3 = (100)^3 cubic cm
= 1000000 cubic cm
Then
1050 kg/m^3 = 1050000/1000000 gm/cm^3
= 1.05 gm/cm^3
I hope the answer comes to your help.
Answer:
Option D
0.83 m/s2
Explanation:
Time is assumed as 10 seconds
First, convert the speeds from km/h to m/s
20 km/h\times \frac {1000 m}{3600 s}=5.555555556 m/s
\approx 5.56 m/s
50 km/h\times \frac {1000 m}{3600 s}=13.88888889 m/s \approx 13.89 m/s
Acceleration, where u and v are the initial and final velocities respectively, t is the time taken to accelerate.
Substituting 13.89 m/s for v, 5.56 m/s for u and 10 s for t then
Power is the rate in which work is being done
The answer is A,B,C that apply. I believe this is the answer i hope this helps have a good day.
