Child A applies a force of 30N tangent to the edge of the disc to cause it to rotate counter clockwise. Child B also applies a force of 20N tangent to the edge of the disc to cause it to counter clockwise. The net torque applied to the disc causes an angular acceleration of 8.33rad/s^2. a) What is the moment of inertia of the solid plastic disc?

High-intensity focused ultrasound (HIFU) is one treatment for certain types of cancer. During the procedure, a narrow beam of high-intensity ultrasound is focused on the tumor, raising its temperature to nearly 90°C and killing it. A range of frequencies and intensities can be used, but in one treatment a beam of frequency 4.40 MHz produced an intensity of 1425.0 W/cm. The energy was delivered in short pulses for a total time of 3.40 s over an area measuring 1.80 mm by 5.40 mm. The speed of sound in the soft tissue was 1580 m/s, and the density of that tissue was 1509.0 kg/m?.

Which function representing the thermometer reading, T, at any given time t (in minutes) is correct?a. dT/dt= k(T-22)b. dT/dt= -k(T-22)c. dt/dT= k(T-22)d. dt/dT= -k(T-22)
1. Thermal equilibration in a two-level atomic system: purely radiative case. Suppose a collection of two-level atoms has a specified radiative decay rate Yrad, = and no nonradiative decay, Ynr 0. The atoms are pre-cooled to absolute zero for long enough to come into equilibrium with №₂ 0, and then are suddenly moved at t = 0 into an enclosure with walls held at a finite temperature Trad. Find formulas for the populations N₁(t) and N₂(t), and for the temperature Ta(t) of the collection of atoms for t > 0. =

Q4: When you are sick your body temperature may be 39.0oC, compared to normal body temperaturegiven by 36.8oC. It was observed that body increased 0.525 MJ of heat energy. Calculate your mass? Takespecific heat of human body as Chaman=3470 J/kgoC. Human body cannot survive without sufficient watercontent in body. Justify your opinion based on scientific knowledge. If you replace water content of bodywith some other liquid, what changes you can observe?
Q20. A certain gas in a closed container at 0.001 atmospheres of pressure is irradiated with ionizing radiation, causing on average one electron to be stripped off each atom. The ionizing radiation also heats the gas from 20°C to 3000°C. The resulting ionized gas ("plasma") behaves like an ideal gas. What is the pressure in the plasma? a. 4.92'103 Pa b. 3.04'105 Pa O c. 1.23'103 Pa d. 2.26'103 Pa Clear my choice
PLEASE NEED IT asap BEFORE 9:10PM pleasseee. Thank you soo much!! I rate u 5 stars. Kindly answer it correctly ? Before time runs out… just limit to 5 sentences Why does droplet of water evaporate slower when dropped in a very hot surface compared when it is dropped in a relatively cooler surface.
1. When the sun is directly overhead, the thermal energy incident upon the earth is about 1.4 × 106 ergs- cm-2-sec-¹. The diameter of the sun is about 1.6 × 10¹¹cm, and the distance from the sun to the earth is about 1.3 × 10¹3 cm. Assuming the that the sun radiates like a black body, use the expression I = σeT4 to estimate its surface temperature. 2. Integrate the expression 8πhc² 1 15 exphc/kXT –1 over all λ, and show that the temperature dependence of the result is T4. I(x) dx -dλ
