Explanation

Pyrometers can be broadly classified into two categories optical pyrometers and infrared radiation pyrometers. Optical pyrometers They are designed for measuring thermal radiation in the visible spectrum. They measure the temperature of extremely hot objects based on the color of the visible light they emit.

Tresset [83]

Answer: C

one wavelength

Explanation:

The bright spots are as a result of constructive interference, which occurs when the path length differs by multiples of one wavelength. The first order maximum varies by exactly one wavelength.

A current of 1.75 A flows through a 55.4 Ω resistor for 9.5 min. How much heat was generated by the resistor? Answer in units of
kirill115 [55]

Answer:

9.67\times 10^4 J

Explanation:

We are given that

Current=I=1.75 A

Resistance =R=55.4 ohm

Time=t=9.5 min=9.5\times 60=570 s

1 min=60 s

We have to find the heat generated by the resistor.

We know that

Heat=E=I^2Rt

Using the formula

Heat,E=(1.75)^2\times 55.4\times 570=9.67\times 10^{4} J

Hence, the heat generated by the resistor =9.67\times 10^4 J

A disk of radius 10 cm is pulled along a frictionless surface with a force of 16 N by a string wrapped around the edge. At the i
drek231 [11]

Answer:

t = 0.2845Nm (rounded to 4 decimal places)

Explanation:

The disk rotates at a distance of an arc length of 28cm

Arc length = radius × central angle × π/180

28cm = 10cm × central angle × π/180

Central angle = \frac{28}{10} × 180/π ≈ 160.4°

Torque (t) = rFsin(central angle) , where F is the applied force

Radius in meters = 10/100 = 0.1m

t = 0.1m × 16N × sin160.4°

t = 0.2845Nm (rounded to 4 decimal places)
