A 30-N iPad is dropped from a height of 10 m and strikes the ground with a speed of 13 m/s.
Ede4ka [16]

Answer:

Initially the PE of the object was W * h = 30 * 10 = 300 Joules

The KE of the object when it struck the ground was 1/2 M v^2

KE = 1/2 * 30/9.8 * 13^2 = 259 J

So the object lost 41 J to friction during the fall

Since Work = Force * distance

Force = 41 J / 10 m = 4.1 N  (the average force of friction)

Como determino la densiad de un objeto?
sveta [45]

Answer:

La densidad (más precisamente, la densidad de masa volumétrica; también conocida como masa específica), de una sustancia es su masa por unidad de volumen. El símbolo más utilizado para la densidad es la letra griega en minúsculas rho), aunque también se puede utilizar la letra latina D. Matemáticamente, la densidad se define como masa dividida por volumen: .m/V donde es la densidad, m es la masa y V es el volumen. En algunos casos (por ejemplo, en la industria del petróleo y el gas de los Estados Unidos), la densidad se define libremente como su peso por volumen unitario, aunque esto es científicamente inexacto – esta cantidad se llama más específicamente peso específico.

The sun is 150,000,000 km from the earth.
aniked [119]

Answer:

<h3>What is the angular speed of the earth around the sun? </h3>

It takes the Earth approximately 23 hours, 56 minutes and 4.09 seconds to make one complete revolution (360 degrees). This length of time is known as a sidereal day. The Earth rotates at a moderate angular velocity of

7.2921159 × 10 {}^{ - 5}  \:  \:  \frac{radians}{second}

<h3>What is the tangential speed of the earth? </h3>

The earth rotates once every 23 hours, 56 minutes and 4.09053 seconds, called the sidereal period, and its circumference is roughly 40,075 kilometers. Thus, the surface of the earth at the equator moves at a speed of 460 meters per second--or roughly 1,000 miles per hour.
