Answer:
, it will sink
Explanation:
The density of an object is given by

where
m is the mass of the object
V is its volume
For the body in the problem, we have
m = 4 kg = 4000 g

Therefore, its density is

And the object will sink in water, because its density is larger than that of water, which is
. (an object sinks when its density is larger than that of water, otherwise it floats).
Acceleration is equal to the change in velocity per unit time. In this case, velocity has changed from 17.7 m/s to 14.1 m/s, which is a decrease of 3.6 m/s. This takes place in 12 seconds, so the average acceleration is 3.6 m/s / 12s = 0.3 m/s^2. The direction of this acceleration is south, since the car's northbound speed is decreasing.
Answer:

Explanation:
From the question we are told that:
Water index of refraction 
Glass index of refraction 
Generally the equation for Brewster's law is mathematically given by



Therefore Angle of incident to plane \mu (normal at 90 degree to the surface)



310.093k.
Given,
Best temperature for enzymes to work = 98.6°F
Unknown :
We need to convert the temperature from fahrenheit to kelvin.
Writing down the equation to be used in the problem's solution correctly:
K = (F x 0.55) + 255.37
F = (K - 255.37) x 1.8
The temperatures are expressed in kelvin (K) and fahrenheit (F), respectively.
There first equation would be significantly more quicker to use :
K = (98.6 x 0.555) + 255.37
= 54.723 + 255.37
= 310.093K
➤ The activity and rate of an enzyme reaction typically increase with temperature, while a decrease in temperature slows the enzymatic reaction. Each enzyme's activity peaks at its individual optimum temperature, and it decreases above and below that point.
