To measure specific heat, the student flows air with a velocity of 20 m/s and a temperature of 25C perpendicular to the length

of the tube, as illustrated below. In this time she heats the tube electrically, passing a current of 50 mA through the tube wall. The initial temperature of the tube is 25 C. After 10 min of heating, a thermocouple buried inside the tube wall measures a temperature of 31.2 C. The tube core is sealed and the heat lost from the internal surface of the tube is negligible during measurements. Furthermore, the tube is suspended on two thermally insulating supports. What is the specific heat of the tube?

A book, that has a mass of 0.5 grams, is pushed across a table with a force of 20 newtons. What is the acceleration of the book?
Bas_tet [7]

Answer:

4\cdot 10^4 m/s^2

Explanation:

The acceleration of an object is given by Newton's second law:

a=\frac{F}{m}

where

F is the net force applied on the object

m is the mass of the object

For the book in the problem, we have:

m=0.5 g =5\cdot 10^{-4} kg is the mass

F=20 N is the force applied

Substituting into the formula, we find the acceleration:

a=\frac{20 N}{5\cdot 10^{-4} kg}=4\cdot 10^4 m/s^2

A car is accelerating at a rate of 35 m/s2 and has a resulting velocity increase from 17 m/s to 26 m/s. How long did it take to
harina [27]

Answer:The answer is (60 mph - 0 mph) / 8s = (26.8224 m/s - 0 m/s) / 8s = 3.3528 m/s 2 (meters per second squared) average acceleration. That would be 27,000 miles per hour squared.

A squirrel jumps down from a tall tree. Assuming the squirrel is in free fall, how far will it have fallen in 1.5 seconds?
snow_tiger [21]
D = 1/2gt^2 <-- free fall formula

d = (0.5)(9.81)(1.5^2)
d = 11.03625
d = 11.04 m

hope this helps and have a great day :)
