Kepler's first "law":
The orbits of the planets are ellipses, with the sun at one focus.
This would include Mars.
Answer:
A compass can detect a magnetic field and show its direction. Iron filings can show the shape of a magnetic field. A gaussmeter can detect a field and indicate its strength.
Explanation:
Answer:
266 g or 0.266 kg
Explanation:
The formula for specific heat capacity is given as,
Q = cm(t₂-t₁) ..................... Equation 1
Where Q = Heat Energy, c = specific heat capacity of Aluminum, m = mass of the aluminum fins, t₁ = initial temperature, t₂ = final temperature.
make m the subject of the equation,
m = Q/c(t₂-t₁)................... Equation 2
Given : Q = 2571 J, c = 0.897 J/g.°C, t₁ = 15.73 °C, t₂ = 26.50 °C.
Substitute into equation 2
m = 2571/[0.897×(26.5-15.73)]
m = 2571/9.661
m = 266 g or 0.266 kg
Hence the mass of the Aluminum fins = 266 g or 0.266 kg
They all have to do something with physics?
Answer:
Explanation:
From the question we are told that:
Time 
Angular displacement 
Final Angular velocity 
Let
Angular acceleration 
Generally the equation for Initial Angular velocity 
is mathematically given by
Also,Initial Angular velocity is mathematically given by
Therefore substitution
Substitution in the 2nd equation for Initial Angular velocity
