Answer:

C. Hackers might steal it for personal gain.

Explanation:

One of the disadvantages of stored digital data is that hackers might steal it for personal gain.

Most digitally stored data can be accessed by hackers who writes some malicious instructions in order to gain access to these stored information.

Also, some of the digitally stored data can be come corrupted due to viruses.
When the keys and passwords used to encrypt a digital data is mistakenly released, it can cause serious harm to the stored data.
Hackers makes use of flaws in the program back end to their own use and benefit.

A 0.0780 kg lemming runs off a 5.36 m high cliff at 4.84 m/s. what is its potential energy (PE) when it is 2.00 m above the grou

zloy xaker [14]

Answer:

1.5288 J

Explanation:

We can use the Energy conversion law

Energy can not be made or destroyed. It can only be converted to another form of energy

Potential Energy (PE) is the energy an object has due to its height of the location

<em>PE = mass * gravitational acceleration * height from the ground</em>

Simply here , lemming had a PE and KE also.

(g = 9.8 m/s²)

PE = 0.0780 * 9.8 *2

= 1.5288 J

A potter spins his wheel at 0.98 rev/s. The wheel has a mass of 4.2 kg and a radius of 0.35 m. He drops a chunk of clay of 2.9 k

Bad White [126]

Answer:

$v_{f,w} = 1.791\,\frac{m}{s}$ , $v_{f,c} = 0.972\,\frac{m}{s}$

Explanation:

The situation can be modelled by applying the Principle of Angular Momentum Conservation:

$I_{w} \cdot \omega_{o} = (I_{w} + I_{c})\cdot \omega_{f}$

The final angular speed is:

$\omega_{f} = \frac{I_{w}}{I_{w}+I_{c}}\cdot \omega_{o}$

$\omega_{f} = \left(\frac{\frac{1}{2}\cdot (4.2\,kg)\cdot (0.35\,m)^{2} }{\frac{1}{2}\cdot (4.2\,kg)\cdot (0.35\,m)^{2} + \frac{1}{2}\cdot (2.9\,kg)\cdot (0.19\,m)^{2}}\right)\cdot (0.98\,\frac{rev}{s} )\cdot \left(\frac{2\pi\,rad}{1\,rev} \right)$

$\omega_{f} \approx 5.116\,\frac{rad}{s}$

The tangential velocities of the wheel and the clay are, respectively:

$v_{f, w} = (0.35\,m)\cdot (5.116\,\frac{rad}{s} )$

$v_{f,w} = 1.791\,\frac{m}{s}$

$v_{f, c} = (0.19\,m) \cdot (5.116\,\frac{rad}{s} )$

$v_{f,c} = 0.972\,\frac{m}{s}$

Which planet moves faster in its orbit: jupiter or neptune? explain?

Setler79 [48]

<span>Jupiter moves faster than neptune in its orbit. It is because jupiter is closer to sun than neptune. The time taken to move on the orbit depends upon the distance from the sun. The length of orbit increases with increasing the distance from the sun and hence the speed also varies accordingly.</span>
