Design an experiment (Fair Test) to find out what would be a good insulator for a dog house.

1 answer:

4 0

Have 5 (or any number) doghouses each with a different insulator. Make sure the other variables are controlled so the experiment if fair. Put a thermometer inside the doghouse and record the temperature inside each doghouse. Whatever doghouse has the highest temperature is the best insulator.

The answer is 0.981 J

E = m · g · h<span>
E - energy
m - mass
g - gravitational acceleration
h - height

We know:
E = ?
m = 0.10 kg
g = 9.81 m/s</span>²
h = 1 m

E = 0.10 kg * 9.81 m/s² * 1 m = 0.981 J

Acceleration toward the center of a curved path is called

Serggg [28]

Answer:

Centripetal acceleration.

Explanation:

Centripetal acceleration is a property of a body moving in a uniform circular path and it is directed radially towards the center of the circle in which body is rotating.

The force which causes this acceleration is centripetal force which is also directed towards the center of the circle and pulls the body towards its center.

It is calculated through following formula

$a=v^2/r$

where v is velocity and r is the radius of the circle.
