Three masses (3 kg, 5 kg, and 7 kg) are located in the xy-plane at the origin, (2.3 m, 0), and (0, 1.5 m), respectively.
a) determine the center of mass of the system.
b) a 6 kg mass is added to the system. this four-mass system has a new center of mass at the origin. what is the location of the 6 kg mass?

t2 equal the displacement of the particle over the same time period if t2> t/2? hint: consider a sine wave starting at t1=0, then consider a closing wave starting at t1=0, for your explanatio

mass number of uranium 238 is sum of number of proton and neutrons in it

while atomic number is just number of protons

so total number of protons in it = 92

total number of neutrons in it = 238   - 92 = 146

mass of proton = 1.0073 amu

mass of neutron = 1.0087 amu

now for the calculation of mass of nuclei is given as

so option b is correct

work requires a force which causes: motion

the answer to your question is high voltage and high currency
