Im not 100% sure but i think its bromine.
Hope this helps ^_^
THE ANSWER IS B HOPE I COULD HELP
A frog can be many different colours. It appears green under normal 'white' light because it absorbs all the other colours in the light's spectrum apart from green. It reflects the green light back and that is picked up by your eye.
If the light is red, there is no green in the spectrum of the light, only red. So, the red light will be absorbed and there is no green to be reflected back for you to see. Therefore, the frog will not look green.
Answer:
change in entropy is - 5.7627 J/K
Explanation:
Given data
temperature = 22.0°C = 22 + 273 = 295 K
work is done = 1700 J
to find out
change in entropy
solution
we know that change in entropy = Q /T ......1
from 1st law of thermodynamic we know
Q =W for change in internal energy = 0
Q = -1700 J
so from equation 1
change in entropy = - 1700 / 295
change in entropy = - 5.7627
so change in entropy is - 5.7627 J/K
Ok so momentum is the product of mass and velocity. Its SI unit is Kg m/s
The marble's velocity is 0.5 cm/s and it's mass is 1.5.
Multiply this -> 0.5 * 1.5 = 0.75 g cm/s
Usually everything in Physics is converted into SI units therefore the SI measurement of the marble is 0.00000075 Kg m/s
Hope this helps :).
