Answer:
R = 11.8 ohms
Explanation:
Formula
R = R_ref[1 + a(T - T_ref)]
Givens
- R_ref = 10 ohms
- T_ref = 20oC
- T = 65oC
- a = 0.004
- R = resistance at 65oC = ???
Solution
R = 10*[1 + 0.004(65 - 20)]
R = 10*[1 + 0.004(45)]
R = 10*[1 + 0.18]
R = 10*(1.18)
R = 11.8 ohms
Be sure you understand not to add the 1 and 0.004 together. You don't get 1.004 at any point of the solution. If you do, you won't know what to do (exactly) with the 45.
Answer:
24 cm/s
Explanation:
Applying
Pythagoras theorem,
a² = b²+c²............. Equation 1
Where a = resultant, b = vertical component, c = horizontal component
From the question,
Given: a = 26 cm/s, c = 10 cm/s
Substitute these values into equation 1
26² = b²+10²
676 = b²+100
b² = 676-100
b² = 576
b = √576
b = 24 cm/s
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.
