Digital storage helps in storing large amounts of data in a small amount of space and easily sharing information with anyone else. Digital items are simple to edit, enhance, or crop.

Cloud storage is a data deposit model wherein digital data including such documents, photos, and so on are stored on virtual or cloud servers hosted by external parties.

It enables you to store data on an offsite storage system and access it whenever necessary.

Thus, the correct options are A and C.

Answer:

How will the electrostatic force be changed if the distance between two electric charges is tripled?

B) 3 times the original force

Explanation:

An electric lamp transfers 500j in 5s

So in 1s = 500/5

= 100

So, it's strength is 100j/s

So, 100j in 1s

Answer:

6m/s

Explanation:

Given parameters:

Initial velocity  = 0m/s

Acceleration  = 2m/s²

Distance  = 9m

Unknown:

Final velocity = ?

Solution:

To solve this problem, we use the expression below:

         v²  = u²  + 2as

v is the final velocity

u is the initial velocity

a is the acceleration

s is the distance

        v²   = 0² + (2 x 2 x 9) = 36

        v  = 6m/s

Answer:

The GPE, stored is 640 Joules

Explanation:

The given parameters are;

The given mass of the astronaut, m = 80 kg

The height of the top of the lunar lander to which the astronaut climbs, h = 5 m

The gravity strength on the moon, g = 1.6 N/kg

The Gravitational Potential Energy, GPE, stored is given according to the following equation;

GPE stored = m·g·h

Therefore, by substituting the known values, we have;

GPE Stored = 80 kg × 1.6 N/kg × 5 m = 640 Joules

The GPE, stored = 640 Joules.

Explanation:

Answer:

The power expended by the car during the acceleration is 116.38KW

Explanation:

Power is a term that defines the rate at which energy is expended whenever work is done.

Power can be given as Force X velocity.

Force can be found using the formula:

F = mass X acceleration.

In this case,

F = 1100kg X 4.6m/s2

F = 5060 N

The final velocity, v of the car can be obtained from this formula:

v = u+ at

U = initial velocity = 0 (since the car started from rest)

a = acceleration = 4.6m/s2

t = time = 5 seconds

v = 0 + 4.6 X 5 = 23 m/s

Therefore, the power expended is 5060N X 23m/s=116,380W

The power expended by the car during the acceleration is 116.38KW

Answer:

v = 8 m/s

Explanation:

p = m × v

16 = 2 × v

2v = 16

v = 16/2

v = 8 m/s

The velocity is 8 m/s

The calculation can be done as follows;

Mass= 2kg

momentum= 16 kg

The formula is;

momentum= mass × velocity

16= 2 × v

16= 2v

v= 16/2

v= 8

Hence the velocity is 8m/s

Answer:

[tex]4.5\ \text{N}[/tex]

Explanation:

[tex]F_1[/tex] = Gravitational force between the objects = [tex]18\ \text{N}[/tex]

[tex]r_1[/tex] = Initial distance between the two objects

[tex]r_2[/tex] = Final distance between the two objects = [tex]2r_1[/tex]

Gravitational force between two objects is given by

[tex]F=\dfrac{Gm_1m_2}{r^2}[/tex]

So

[tex]F\propto \dfrac{1}{r^2}[/tex]

[tex]\dfrac{F_2}{F_1}=\dfrac{r_1^2}{r_2^2}\\\Rightarrow \dfrac{F_2}{F_1}=\dfrac{r_1^2}{(2r_1)^2}\\\Rightarrow \dfrac{F_2}{F_1}=\dfrac{1}{4}\\\Rightarrow F_2=\dfrac{F_1}{4}\\\Rightarrow F_2=\dfrac{18}{4}\\\Rightarrow F_2=4.5\ \text{N}[/tex]

The new force of attraction between the objects is [tex]4.5\ \text{N}[/tex].

Answer:

-0.28 m/s²

Explanation:

acceleration, a = (v - u)/t where u = initial velocity = 30 km/hr = 30 × 1000/3600 = 8.33 m/s and v = final velocity = 20 km/hr = 20 × 1000/3600 = 5.56 m/s and t = time = 10 s.

Substituting the values of the variables into the equation, we have

a = (v - u)/t

= (5.56 m/s - 8.33 m/s)/10 s

= -2.77 m/s ÷ 10 s

= -0.277 m/s²

≅ -0.28 m/s²

If a car is coasting backward downhill at a speed of 3. 0 meters / s when the driver gets the engine started. After 2.5 sec, the car is moving uphill at 4.5 meters / second . Assuming that uphill is the positive direction the average acceleration of the car would be  3.0 meters / second².

The rate of change of the velocity with respect to time is known as the acceleration of the object. Generally, the unit of acceleration is considered as meter / seconds².

As given in the problem If a car is coasting backward downhill at a speed of 3. 0 meters / s when the driver gets the engine started. After 2.5 sec, the car is moving uphill at 4.5 meters / second .

The average acceleration of the car  = + 4.5 - ( - 3 .0) / 2.5

                                                              = 3.0 meters / second ²

Thus , the average acceleration of the car would be 3.0 meters / second².
