$w = f.d$
$3500 = 70x \\ x = \frac{3500}{70} = 50$
it will move 50 m

good luck

Work = Force * distance
Force = 70 N
Work = 3500 J

3500 = 70d
d = 3500/70 = 50 m

If a 20 kg box is accelerating upward at 8 m/s^2 , what is the magnitude of the upward force

shusha [124]

Answer:

356 N

Explanation:

Newton's second law of motion describes the relationship between an object's mass and the amount of force needed to accelerate it.

here there is a weight acting downwards on the object , yet it is accelerating upwards shows that there is a net force upwards

Applying Newtons second law of motion upwards ,

Force = mass *acceleration

Upward force - m*g = m *a

F_up= 20 *8 + 20 * 9.8

= 356 N

Upward force= 160 N

The capacitors are disconnected from the potential difference without allowing them to discharge. They are then reconnected in p

Dvinal [7]

Answer:

net voltage will become half that of initial voltage now

Explanation:

Initially two capacitors are connected across a given voltage difference

So the net charge on the two capacitors is given as

$Q = C_{eq} V$

$Q = \frac{C}{2} V$

now when these are connected in parallel with no change in charge

then total charge on each plate is given

$Q = \frac{CV}{2} + \frac{CV}{2}$

$Q = CV$

also we know that

$C_{eq} = 2C$

now we will have

$V_{net} = \frac{Q_{net}}{C_{eq}}$

$V_{net} = \frac{CV}{2C} = \frac{V}{2}$

so net voltage will become half that of initial voltage now

How does south African law ensure that people who are living with HIV/AIDS are not discriminated against

Svetach [21]

The African law ensures that people who are living with HIV/AIDS are not discriminated by the society by emphasizing that they must be protected by the law and enjoy the rights like those people in good conditions. It is in their Bill of Rights that people with HIV/AIDs are not forced to tell others about their status instead they have to enjoy their right to privacy and confidentiality.

.Imagine that you pushed a box, applying a force of 60 newtons, over a distance of 4 meters. how much work have you done? 15 jou

DaniilM [7]

Work=force X distance
Newtons is a measurement of force
4 meters is your distance 60×4=240

240 joules
