Physics
1 answer:
leonid [27]3 years ago
5 0

Answer:

The answer to your question is    m₂ = 38.5 kg

Explanation:

Data

distance = d = 2.1 x 10⁻¹ m

Force = 3.2 x 10⁻⁶ N

m₁ = 55 kg

m₂ = ?

G = 6.67 x 10 ⁻¹¹ Nm²/kg²

Process

1.- To solve this problem use Newton's law of Universal Gravitation.

             F = G m₁m₂ / r²

-Solve for m₂

            m₂ = Fr² / Gm₁

2.- Substitution

            m₂ = (3.2 x 10⁻⁶)(2.1 x 10⁻¹)² / (6.67 x 10⁻¹¹)(55)

3.- Simplification

            m₂ = 1.411 x 10⁻⁷ / 3.669 x 10⁻⁹

4.- Result

            m₂ = 38.5 kg

A piece of aluminum foil has a known surface density of
bija089 [108]

The cube has 6 equal, square, foil faces. The mass of foil for each face is (380/6) milligrams.

The surface area of each piece is (380)/(6•11) cm^2.

The length of each side of the piece is √(380/6•11) cm

That's about 2.4 cm .

It's a cute little foil cube, just under 1-inch each way.

A 2.0-m wire carrying a current of 0.60 A is oriented parallel to a uniform magnetic field of 0.50 T. What is the magnitude of t
konstantin123 [22]

Answer:

The force experienced  is 0.6 N

Explanation:

Given data

length of wire L= 2 m

current in wire I= 0.6 A

magnetic field B= 0.5

The force experienced can be represented as

F= BIL

F= 0.5*0.6*2\\\F= 0.6 N

Use the information presented in the graph to answer
Angelina_Jolie [31]

1) Segments A and C

2) Segment C

3) 40 m/s

4) 0

Explanation:

The graph is missing: find it in attachment.

1)

Here we want to find which segments show acceleration.

Acceleration is defined as the rate of change of velocity of an object; mathematically:

a=\frac{\Delta v}{\Delta t}

where

\Delta v is the change in velocity

\Delta t is the time interval

On a velocity-time graph, an object has acceleration if its velocity, v, changes versus time.

In this problem, we see that this situation occurs in two segments:

- In segment A, where the is a change in velocity (\Delta v>0), so there is an acceleration

- In segment C, where the is also a change in velocity (\Delta v>0), so there is an acceleration

B)

Here we want to find in which segment the object is slowing down.

For an object to slow down, the final velocity must be less than the initial velocity, which means that the change in velocity must be negative:

\Delta v = v-u

where

v is the final velocity

u is the initial velocity

For the graph in the problem, we see that:

- For segment A, the final velocity is greater than the initial velocity, so the object is speeding up

- For segment B, the final velocity is equal to the initial velocity, so the object is neither speeding up nor slowing down

- For segment C, the final velocity is less than the initial velocity, so the object is slowing down

So, the segment in which the object is slowing down is segment C.

C)

The velocity of an object is defined as the displacement covered per unit time:

v=\frac{d}{\Delta t}

where

d is the displacement

\Delta t is the time elapsed

On a velocity-time graph, the velocity is represented on the y-axis, while the time is represented on the x-axis.

Therefore, it is possible to read directly the value of the velocity from the y-axis.

For segment B, we see that the velocity is constant, and its value is

v_B=40 m/s

D)

As we stated before, the acceleration of an object is the rate of change of its velocity:

a=\frac{\Delta v}{\Delta t}

where

\Delta v is the change in velocity

\Delta t is the time interval

Here we want to find the acceleration for segment B. For this segment, we observe that:

- The velocity does not change, so \Delta v = 0

- The time interval is \Delta t = 9 s - 4 s = 5 s

Therefore, the acceleration in segment B is:

a_B=\frac{0}{5s}=0
