Answer:

9.9 m

Explanation:

From the question given above, the following data were obtained:

Force (F) = 40 N

Workdone (Wd) = 395 J

Height (h) =?

The height can be obtained as follow:

Potential energy = mgh = Fh

395 = 40 × h

Divide both side by 40

h = 395 / 40

h = 9.9 m

Thus, the height is 9.9 m.

If the mass of the Jupiter is 1.9*10 kg and radius is fbx loom what is acclerallon due to gravity on the supiter ?

Bond [772]

Answer:

$g=25.92\ m/s^2$

Explanation:

Given that,

The mass of the Jupiter, $M=1.9\times 10^{27}\ kg$

The radius of Jupiter, $r=69,911\ km=69911\times 10^3 km$

We need to find the acceleration due to gravity on Jupiter. The formula is

$g=G\dfrac{M}{r^2}$

Put all the values,

$g=6.67\times 10^{-11}\times \dfrac{1.9\times 10^{27}}{(69911\times 10^3)^2}\\\\g=25.92\ m/s^2$

So, the value of acceleration due to gravity on the Jupiter is $25.92\ m/s^2$ .

For a particular scientific experiment, it is important to be completely isolated from any magnetic field, including the earth's

Alexus [3.1K]

Answer:

50000 μT

Explanation:

From the given information:

the diameter of the loop = 1.0 mm = 0.001 m

no of turns (N) = 200

current (I) = 0.199 A

radius = d/2 = 0.001/2

= 5 × 10⁻⁴ m

Recall that;

the magnetic field at the centre of circular wire is:

$= \dfrac{\mu I N}{2R}$

$= \dfrac{4 \pi \times 10^{-7} \times 200 \times0.199}{2\times 5\times 10^{-4}}$

= 0.05 T

= 50000 μT

Since the centre of the earth's magnetic field is given to be equal to the magnetic field produced by the wire, then:

the earth's magnetic field = 50000 μT

M+2-4=3 solve and get 50 pts

Katen [24]

Hey!

First, let's write the problem.
$M+2-4=3$
Subtract the numbers, we would do the following operation, $2-4=-2$
$M-2=3$
Add 2 to both sides.
$M-2+2=3+2$

This tells us that our final answer would be,
$M=5$

Thanks!
