A garage door opener has a power rating of 350 watts. If the door is in operation for 30 seconds, how many joules of energy are
Ksju [112]
Because of the hint we can conclude what equation we need to solve this problem. We have power and duration that means that we need to express energy:

1 joule = 1watt * 1 second
or
E (energy) = P (power) * t (time duration)
E = 350 * 30 = 10500 joules.

You're collecting data in BeyondLabz for an object in free fall, subject to air resistance. How do you know when you've collecte
denis23 [38]

Enough data points would have been collected when specific data for upward and downward motion are collected.

<h3>What is a Data point?</h3>

A data point is a discrete unit of information. This information is always unique.

<h3>Free fall</h3>

An object subjected to free fall is under the influence of gravity. An object subjected has different time of motion for upward and downward motion.

Thus, we can conclude that enough data points would have been collected when specific data for upward and downward motion are collected.

Please help me to find out my mistake
Scrat [10]

From the calculation, the speed of sound at 10 K is 63.5 m/s.

<h3>What is the speed of sound?</h3>

We know that the speed of sound is directly proportional to the temperature of the body thus we can write;

V1/V2 = √T1/T2

Then;

T1 = 0 degrees or 273 K

T2 = 10 K

V1 = 330 m/s

V2 = ?

330/T2 = √273/10

330/T2 = 5.2

330 = 5.2T2

V2 = 330/5.2

V2 = 63.5 m/s
