I would say the answer is D

A hygrometer is an instrument used to measure relative humidity. ... To determine the relative humidity, the temperatures are taken from the dry-bulb thermometer and the temperature difference between the wet and dry bulb thermometers.

hygrometer is a weather instrument used to measure the amount of humidity in the atmosphere. There are two main types of hygrometers -- a dry and wet bulb psychrometer and a mechanical hygrometer.

A bee loaded with pollen flies in a circular path at a constant speed of 3.20 m/s. If the mass of the bee is 133 mg and the radi
BaLLatris [955]
<h3><u>Answer;</u></h3>

Centripetal acceleration = 0.931 m/s²

Centripetal force = = 1.234 × 10^-4 Newtons

<h3><u>Explanation;</u></h3>

Centripetal acceleration is given by the formula v²/r, where r is the radius of the circular path and v is the velocity of a body;

Centripetal acc = 3.2²/11

                          = 0.931 m/s²

Centripetal force is a force that acts on an object or a body in circular path and is directed towards the center of the circular path.

Centripetal force is given by the formula;

mv²/r ; where m is the mass of the body, r is the radius of the circular path and v is the velocity of a body;

mass = 33 mg or 1.33 × 10^-6 kg, velocity = 3.20 m/s and r = 11 m

Therefore;

Centripetal force = (1.33 ×10^-6 × 3.1²)/ 11

                            = 1.234 × 10^-4 Newtons

The coordinates of a bird flying in the xy plane are given by x(t)=αt and y(t)=3.0m−βt2, where α=2.4m/s and β=1.2m/s2. Calculate
yuradex [85]
     The derivative of the function space as a function of time is equal to a function of speed as a function of time.

x(t)=2.4t \\  \frac{x(t)}{t}=t \\ v_{x}(t)=t \\  \\ y(t)=3-1.2\times t^2 \\  \frac{y(t)}{t}=1.2\times2t \\ v_{y}(t)=2.4t
   
     The velocity vector is given by the vector sum of the velocities of  both axes.

v_{R}^2(t)=v_{x}^2(t)+v_{y}^2(t) \\ v_{R}^2(t)=(t)^2+(2.4t)^2 \\ \boxed {v_R(t)=2.6t}

If you notice any mistake in my english, please let me know, because I am not native.
