Explain why the thermometer has thin walls on its bulb?

1 answer:

The glass around the bulb in a clinical thermometer (the conventional one) is <span>thin because glass is not a good conductor of heat. The clinician and the
</span>patient don't want to wait half an hour to get a good temperature reading. By <span>using the thinner glass, the transfer of heat into the thermometer's fluid will</span>

An airplane flies eastward and always accelerates at a constant rate. At one position along its path, it has a velocity of 34.5

Inessa05 [86]

Answer:

the acceleration of the airplane is 5.06 x 10⁻³ m/s²

Explanation:

Given;

initial velocity of the airplane. u = 34.5 m/s

distance traveled by the airplane, s = 46,100 m

final velocity of the airplane, v = 40.7 m/s

The acceleration of the airplane is calculated from the following kinematic equation;

v² = u² + 2as

$2as= v^2 - u^2\\\\a = \frac{v^2 - u^2}{2s} \\\\a = \frac{(40.7)^2 -(34.5)^2}{2 \times 46,100} \\\\a = 5.06 \ \times \ 10^{-3} \ m/s^2$

Therefore, the acceleration of the airplane is 5.06 x 10⁻³ m/s²

A loop of wire lays flat on a horizontal surface in an area with uniform magnetic field directed vertically down. Magnetic field

zimovet [89]

Answer:

B. counterclockwise

Explanation:

We shall apply Lenz's law to find direction of induced current . According to it , direction of induced current is such that the magnetic field produced by it will try to nullify the change in magnetic field that produces it. Increase in magnetic field in down ward direction is producing it so to nullify it , magnetic field induced will be in upward direction. For it current induced will be anticlockwise.
