Answer:
Venus observation.
Explanation:
Galileo had learned regarding the heliocentric (Sun-centered) idea of Copernicus, and acknowledged it. However, the theory was proven by Galileo's observations of Venus. Galileo concluded that Venus should travel round the Sun, sometimes passing behind and then beyond, instead of directly rotating around the Earth.
Answer:
because the velocity and mass are more with susan
Explanation:
veloctiy can change ones mass and the energy they produced
as much your weight is you ts=ake more time or effort and energy to walk , run, swing
Answer:
b) 3.72m/s²
c) 9.33*10^5
d) 9.33*10^5
e) 11.85 hrs
Explanation:
a) to confirm that gEarth is about 98 m/s².
Let's use the formula:


= 9.78 m/s²
=> 9.8m/s²
b) Given:

r = 2106 miles


=3.72 m/s²
c) we use:



d) Let's take the force of gravitybon earth due to satellite as our answer in (c) because the Earth's gravitational force on a GPS satellite and the force of gravity on a GPS satellite on earth are equal and opposite (two mutual forces).

e) In a circular motion,
Gravitional force = Centripetal force.


Solving for v, we have

v = 3886m/s
Therefore,
v = 2πR/T

Solving for T, we have:
T = 42650seconds
Convert T to hours
T = 42650/60*60
T = 11.86hrs
Missing part in the text of the problem:
"<span>Water is exposed to infrared radiation of wavelength 3.0×10^−6 m"</span>
First we can calculate the amount of energy needed to raise the temperature of the water, which is given by

where
m=1.8 g is the mass of the water

is the specific heat capacity of the water

is the increase in temperature.
Substituting the data, we find

We know that each photon carries an energy of

where h is the Planck constant and f the frequency of the photon. Using the wavelength, we can find the photon frequency:

So, the energy of a single photon of this frequency is

and the number of photons needed is the total energy needed divided by the energy of a single photon:
