Answer:
C.Supersaturated
Explanation:
There are three types of solution:
<u>SATURATED SOLUTION</u>:
It is the solution that contains maximum amount of solute dissolved in a solution in normal conditions.
<u>UNSATURATED SOLUTION</u>:
It is the solution that contains less than the maximum amount of solute dissolved in a solution in normal conditions. It has space for more solute to be dissolved in it.
<u>SUPERSATURATED SOLUTION:</u>
It contains more than the maximum amount of solute dissolved in it. Such a solution has no capacity to dissolve any more solute under any conditions.
Since the sugar is no more dissolving in the tea and has settled down. Therefore, the solution is:
<u>C.Supersaturated</u>
Centripetal acceleration is the motion inwards towards the center of a circle. It is given by the square of velocity, divided by the radius of the circular path.
ac = v²/r, where ac is the centripetal acceleration in m/s²
Therefore,
Centripetal acceleration = 3²/20m
= 9/20m
= 0.45 m/s²
Thus, the centripetal acceleration is 0.45 m/s²
The addition of antifreeze to
water in a car radiator causes the freezing point of the mixture to increase. The
answer is letter A. It protects the car radiator from freezing due to cold
temperatures. It is added below the freezing point of water to prevent it from
solidifying.
Scientists think the earliest version of the eye was formed in unicellular organisms, who had something called 'eyespots'. These eyespots were made up of patches of photoreceptor proteins that were sensitive to light. ... Over time, the unicellular creature would evolve, and its eyespot evolved along with it.
Answer:
2550kgm/s
Explanation:
Angular momentum is given as
P=mv
And V=w²r
W=25rad/s
r=34cm approx. 0.34m
V= 25²X 0.34
V=212.5m/s
To find the angular momentum,
P=mv
P= 12 X 212.5
P=2550kgm/s
