A light bulb is supplied with 100 J of energy each

Physics
1 answer:
agasfer [191]3 years ago
8 0

Answer:

a.95J

b.90J

Explanation:

a.Applying energy conservation laws:-

Energy  Into Bulb=Light \ Energy+Thermal \ Energy(Heat \ Energy)

Given  that light energy=5J,and Total Energy=100J

Heat \ Energy= \Total \ Energy- Light \ Energy\\=100J-5J=95J

b. Applying the laws in a above.

Total Energy=100J

Light Energy=10J

Heat \ Energy=100J-10J=90J

Comet is seen after a long period of time. Why?​
lorasvet [3.4K]

Answer:

Long-period comets have orbital periods longer than 200 years. ... Since it is the sublimation of these volatiles from the nucleus of the comet as it nears the Sun that gives rise to the coma and highly-visible tails, long-period comets have more material with which to put on a show.

A car drives around a curve with radius 539 m at a speed of 32.0 m/s. The road is banked at 5.00°. The mass of the car is 1.40 ×
HACTEHA [7]

Answer:

f_r = 150.47 N

Explanation:

given,

r = 539 m

v = 32 m/s

road banked at = 5°

∑ F_x

\dfrac{mv^2}{r}= N sin \theta + f_r cos \theta

∑ F_y = 0

0 = N cos \theta - f_r sin \theta - mg

N = \dfrac{f_rsin \theta + mg}{cos \theta}

\dfrac{mv^2}{r}= (\dfrac{f_rsin \theta + mg}{cos \theta})sin \theta + f_r cos \theta

              = f_r sin \theta tan \theta + mg tan \theta + f_r cos \theta

        f_r = \dfrac{\dfrac{mv^2}{r}- mg tan\theta}{sin\theta tan \theta + cos \theta}

         f_r = \dfrac{\dfrac{1.4\times 10^3 \times 32^2}{539}- 1.4\times 10^{3}\times 9.8 \times 0.087}{0.087 \times 0.087 + 0.996}

f_r = 150.47 N
