Panel surface area =34m×46m=1,564m^2
total power =1564m^2×1390w/m^2
=2173960watts
now you must calculate total energy.
Energy = power×Time
However time must be in seconds so we multiply 2hrs×60min×60s=7200seconds
7200s×2173960w =15,652,512,000 joules of energy
Answer:
1. Planetary Model
2. Protons and Neutrons
Explanation:
1. planetary model is also known as quantum model, which is the model we use nowadays
2. Majority of the mass is from the total of neutrons and protons, electrons are so small that it is not included with the mass
Hope this helps
Answer:
2.11 seconds
Explanation:
We use the kinematic equation for the velocity in a constantly accelerated motion under the acceleration of gravity (g):
Answer:
a) increases
Explanation:
The increase in temperature causes the particles to move much faster. This in turn effects the collision rate of the particle which causes the chemical reaction. Thus the rate of chemical reaction increases.
So, we conclude that the rate of a chemical reaction is directly related to temperature. With increase in temperature there is an increase in the reaction rate and vice versa.
Answer:
22.73 Hz
Explanation:
Frequency = 45.45/2 = 22.73 Hz
