Answer:more, increased
Explanation:
Blood is four to five times more viscous than water.
Viscosity depends upon dissolved substances in blood and it increases as the amount is increases or if the fluid in the blood decreases.
Viscosity is the resistance offered by liquid to the flow and it also depends upon temperature and it decreases with increase in temperature.
The speed of light is approximately 3.00 x 10^8 m/s. Then the next step is to convert m/s into km/s.To determine the time, the distance must be divided with velocity. It will take the light signal 3.3*10^-6 seconds to reach his assistant.
They can't hear an echo in small room because in it the sound can't be reflected back. For an echo of a sound to be heard,the minimum distance between the source of sound and the walls of the roomshould be 17.2 m. Obviously,in asmall room echoes cannot beheard.
Answer:
0.25 m/s
Explanation:
This problem can be solved by using the law of conservation of momentum - the total momentum of the squid-water system must be conserved.
Initially, the squid and the water are at rest, so the total momentum is zero:
After the squid ejects the water, the total momentum is
where
is the mass of the squid
is the velocity of the squid
is the mass of the water
is the velocity of the water
Due to the conservation of momentum,
so
so we can find the final velocity of the squid:
and the negative sign means the direction is opposite to that of the water.
