Answer:
a) 316880878140.2895 Joules
b) 1056.26 Joules
c) 372.80103310622 km²
Explanation:
Energy consumption

Average rate of electrical energy consumption is 316880878140.2895 Joules
Total population = 300 million

Each person consumes 1056.26 Joules.
Efficiency = 0.85
Power from Sun

Area

Converting to km²

Area required to collect the electrical energy used in the United States is 372.80103310622 km²
Sin is the vertical component. So multiply sin 30 and 14. BOOM! You got the answer.

Answer:
A : Positively charged.
Explanation:
In a beta decay an unstable nucleus emits a beta particle (an electron or positron) to compensate the ratio between neutrons and protons in the atomic nucleus. In this case, a proton in the atomic nucleus becomes a neutron, by the emission of a positron(+e) accompanied by an antineutrino from the nucleus.
