Answer:
E = 7.99 *10^{-13} J
Explanation:
the given reaction is
we know that energy is given as
where
m_1 H^1 is mass of proton = 1.672622 *10^{-27}
m_1 H^2 is mass of deuterium = 3.344494 *10^{-27}
m_2 H^3 is mass of He = 5.008234 *10^{-27}
E = [1.672622 *10^{-27} + 3.344494 *10^{-27} - 5.008234 *10^{-27} ] *(3*10^8)^2
E = 7.99 *10^{-13} J

Answer:
D. Validity group
Explanation:
A validity group is not necessarily a component of a normal experiment.
A normal experiment is made up of the dependent variables, independent variables, and most times the control group.
- The dependent variable is one that relies on the outcome of the effect produced from the experimental design
- The independent variable is the one that causes a desired effect under the study.
- The control group is a group that does not receive any treatment nor attenuation of the conditions.
To find the pressure with a given data for the height, you are asked to get the hydraulic pressure. Hydraulic pressure has the following formula:
P = density*acceleration due to gravity*height
Assume that the density of seawater is the same as that for pure water,density = 1000 kg/m^3.
P = 1000 kg/m3*9.81m/s2*9100m
P = 89271000 Pascals or 89.271 megapascals
