Telescope magnifies light coming from distant objects.
Tycho Brahe ( 1546 - 1601 ) was a Danish astronomer known for his accurate astronomical and planetary observations. Tycho tried to produce a model with the best of both Ptolemy ( earth-centered solar system ) and Copernicus ( sun-centered solar system ).
Answer: B ) observation.
Answer:
The volume of the lungs at 5m deep is 4L
Explanation:
Hello!
We can solve this problem considering that the air inside de lungs behave as an ideal gas, and that the temperature is the same at sea leavel and 10 m below the surface, in this case:
P1 V1 = P2 V2 -- (1)
wher P and V stands for pressure and volume, and 1 and 2 for the intial (sea level) and final (5m below) states.
We know that:
P1 = 14.7 psi
V1 = 6 L
And if the pressure exerted by the water adds 14.7 psi to atmospheric pressure so 10 m below the surface, then at 5 m below it must add 14.7/2 psi, therefore:
P2 = (14.7/2) psi + atmospheric pressure = 7.35 psi + 14.7 psi
P2 = 22.05 psi
Solving equation (1) for V2:
V2 = V1 (P1/P2) = 6 L (14.7 psi / 22.05 psi ) = 6 *(2/3) = 4 L
The volume of the lungs at 5m deep is 4L
It has both potential and kinetic energy.
Since the ball is falling through the air its going to keep going faster and faster since gravity is pulling it downward so its not going to stop unless it hits something or someone catches it.
Answer:
1.336 m
Explanation:
q = - 3.77 micro C at y = 0 m
Q = - 4.92 micro C at y = 2.86176 m
Let the electric field is zero at P which is at a distance y from origin.
Electric field at P due to q is equal to the electric field at P due to Q.
2.86176 - y = 1.142 y
2.142 y = 2.86176
y = 1.336 m
Thus, the electric field is zero at y = 1.336 m.
