Why is Saturn almost as big as Jupiter, despite its smaller mass?

gulaghasi [49]

Answer:

c. Jupiter's greater mass compresses it more, thus increasing its density.

Explanation:

The mass of Jupiter is greater in its interior, this mass compresses Jupiter to some extent. Thus, its density is increased. Now, more mass is compressed in the lesser volume. Hence, its size does not increase enormously. On the other hand the mass of Saturn is lesser and also density lower. this gives Saturn a reasonably higher volume.

Hence, option C is correct.

A ball with a mass of 3kg is dropped from the top of a building this is 20m high. what is the velocity of the ball when it is 10

anzhelika [568]

Answer:

Velocity=14[m/s]

Explanation:

We can solve this problem by using the principle of energy conservation, where potential energy becomes kinetic energy.

In the attached image we can see the illustration of the ball falling from the height of 20 meters, at this time the potential energy will have the following value.

$Ep=m*g*h\\where:\\m=3[kg]\\h=20[m]\\$

$Ep=3*9.81*20\\Ep=588.6[J]$

When the ball passes through half of the distance (10m) its potential energy will have decreased by half as shown below.

$Ep=3*9.81*10\\Ep=294.3[m]$

If we know that potential energy is transformed into kinetic energy, we can find the value of speed.

$Ek=\frac{1}{2} *m*v^{2} \\therefore\\v=\sqrt{\frac{Ek*2}{m} } \\v=\sqrt{\frac{294.3*2}{3} } \\\\v=14[m/s]$

If you travel 2 miles west then 4 miles south then what is your displacement in meters

Leokris [45]

Answer:

9656.06 meters because youd go 6 miles and 9656.06 is 6 miles but just in meters. I hope this helps :)

Vector A has magnitude 13.0 m and vector B has magnitude 16.0 m. The scalar product A.B is 116 m2. What is the magnitude of the

Elan Coil [88]

Answer:

$\text{Vector product}=172.66\ m^2$

Explanation:

Given that,

The magnitude of vector A, $|A|=13\ m$

The magnitude of vector B, $|B|=16\ m$

Scalar product of A and B, $A{\cdot} B=116\ m^2$

The formula for the scalar product is given by :

$A{\cdot} B=|A||B|\cos\theta$

Where, $\theta$ is the angle between A and B.

$\cos\theta=\dfrac{116}{13\times 16}\\\\\theta=\cos^{-1}\left(0.5576\right)\\\\\theta=56.11^{\circ}$

The formula for the vector product is given by :

$A\times B=|A||B|\sin\theta\\\\=13\times 16\times \sin56.11\\\\=172.66\ m^2$

So, the vector product between these two vectors is $172.66\ m^2$ .

What do you guys know about emotional intelligence? And how is it used in the real world?

tester [92]

Emotional Intelligence is our own abilities of being able to identify and regulate our own emotions. This is used by individuals in the real world in order to regulate crying in front of everyone for example. Calming ourselves down by breathing is another good example of regulating emotion which plays into emotional intelligence.

Hope this helps mate :D
