Answer:
Current, I = 0.54 A
Resistance, R = 201.6 ohms
Explanation:
Electric power is given in terms of current, I, and voltage, V, as:
P = I*V
I = P/V
The current flowing in the 60 W bulb will be:
I = 60/110 = 0.54 Amps
The resistance can be gotten by using an alternate formula for Power in terms of resistance:
P = V²/R
R = V²/P
R = 110²/60
R = 201.6 ohms
The 60W bulb has a current 0.54A flowing through it and a resistance of 201.6 ohms.
Answer:d
Explanation:
Eiffel tower is made up of puddling of cast iron and trusses to provide fire-resistant material. Around 7000 metric tons of puddling iron is used to construct the Eiffel Tower. The structure composed of four large arched legs, upright on masonry columns that joined to become one.
Effiel tower uses the criss-cross beams structure called trusses which provide strength to the structure. The strength comes from the inherent stability of triangular structures.
Answer:
11.27 m /s
2.98 m / s.
Explanation:
80 km / h = 22.22 m /s
Tanq = 4 / 100
Sinq = .0399
Deceleration acting on inclined plane = g sinq
= 9.8 x .0399
= .3910
Initial speed u = 22.22 m/s
acceleration = - .3910 ms⁻²
v = u - a t
= 22.22 - .3910 x 28
= 22.22 - 10.95
= 11.27 m /s
b ) v² = u² - 2 a s
v² = ( 22.22) ² - 2 x .3910 x 620
= 493.7284 - 484.84
= 8.8884
v = 2.98 m / s.
