What action should you take if you are in debt

Since the graph provided represents voltage and current data for resistor R, the resistance of R is 2.0 Ω

The resistance of a metallic material is its opposition to the flow of electric current.

Resistance is given by R = V/I where

To find the resistance of R, we take the gradient of the graph since reistance R = V/I.

So, the resistance R = ΔV/ΔI where

R = ΔV/ΔI

= (V' - V)/(I' - I)

Taking points from the graph

So, substituting the values of the variables into the equation, we have

R  = (V' - V)/(I' - I)

= (9.0 V - 0 V)/(4.5 A - 0 A)  

= 9.0 V/4.5 A

= 2.0 Ω

So, the resistance of R is 2.0 Ω

The height of the bridge is 1796.895 m if an object falls from the bridge and strike the water below with a velocity of 187.82 m/sec.

Velocity of the object, v = 187.80 m/s

Height of the bridge will be

According to the three equations of motion,

1) First equation Velocity - Time relation states that,

[tex]v = u + at[/tex]

here 'a' will be the acceleration due to gravity i.e g = 9.8 [tex]\frac{m}{secx^{2} }[/tex]

'v' = 187.80  m/s

'u' = 0 m/s

therefore,

[tex]t = \frac{v - u}{a}[/tex]

[tex]t = \frac{187.80 - 0}{9.81}[/tex]

t = 19.14 sec

2) Second equation Position - Time relation states that,

[tex]s = ut + \frac{1}{2} at^{2}[/tex]

here 'a' will be the acceleration due to gravity i.e g = 9.8 [tex]\frac{m}{secx^{2} }[/tex]

'u' = 0 m/s

't' = 19.14 sec

[tex]s = 0 + \frac{1}{2} 9.81 *(19.14^{2})[/tex]

s = 0 + 4.905 * 366.34

s = 1796.895 m

The height of the the bridge is 1796.895 m.

Explanation:

the rilation shhip betveen boats annd volummes are ver expennsive

The buoyancy of a boat and the density of the materials used in its construction have an impact on the connection between its volume and the amount of mass it can support before sinking.

Thus, The buoyancy principle asserts that the upward force a fluid (in this case, water) exerts on a submerged or floating item is equal to the weight of the fluid displaced by the object, which is why a boat floats in water.

A boat moves as much water as its own volume while it is submerged in water.

A boat will float if its total weight, including its passengers and cargo, is less than the weight of the water it moves.

Thus, The buoyancy of a boat and the density of the materials used in its construction have an impact on the connection between its volume and the amount of mass it can support before sinking.

The strength of the gravitational force between two objects depends on two factors, mass and distance exert on each other. If one of the masses is doubled, between the objects is doubled increases, the force of gravity decreases.

Newton's universal law of gravitation states that the attraction force between any two bodies is proportional to the product of their masses and inversely related to the square of the distance between them.

All objects on Earth experience weight, or a gravitational pull that is proportionate to their mass and is imposed by the planet's mass. A measure of the force of gravity is the acceleration that freely falling objects experience. At the surface of the Earth, gravity accelerates at a rate of about 9.8 meters (32 feet) per second each second.

Total Mass = 145 grams

Mass of the empty Beaker = 51 grams

To find

Mass of the liquid

The density of the liquid

Now,

Total Mass = Mass of LIquid + Mass of the empty Beaker

Mass of LIquid = Total Mass -  Mass of the empty Beaker  

Put in the value, we get

Mass of liquid = 145 - 51 grams

Mass of liquid = 94 grams

Answer:

13 m/s

Explanation:

Given average acceleration a and initial velocity  v0 we can compute the final velocity  using the equation

a = (v - v0)/t where t is the time taken to reach final velocity from initial velocity

Here a = 2 m/s² and v0 is the initial velocity when she passes her younger brother v0 = 5m/s.

It takes t = 4 s to pass her older brother at which time her speed is v, say

Then

a = (v - v0)/t

Plugging in known values,

2 = (v - 5)/4

Switch sides:
(v- 5)/4 = 2

Multiply both sides by 4:
v - 5  = 8

v =5 + 8 = 13 m/s - the speed at which she passes her older brother

(i) The angle of inclination of the string to the vertical is 65⁰.

(ii) The tension in the string is determined as 2.11 N.

The angular speed of the string is calculated as follows;

ω = 2πN/60

ω = 2π x 80/60

ω = 8.38 rad/s

v = ωr

v = 8.38 x 0.3 m

v = 2.514 m/s

tanθ = v²/rg

tan θ = (2.514²) / (0.3 x 9.8)

tan θ = 2.15

θ = arc tan(2.15)

θ = 65⁰

T = mv²/r

T = (0.1 x 2.514²) / (0.3)

T = 2.11 N

[tex]V(bar)=46.33(km/hr).[/tex]

Let's refer to the formula of average velocity.

Formula: [tex]V(bar)=\frac{td}{ct}[/tex], where td is the todal displacement, and ct is the change in time.

Since we're trying to find out the average velocity of the whole event (from time 0 when the car started moving to time 30 minutes when it finished the trip), we must take 30 minutes as our change in time.

Now, we need to find the distance traveled by the car on each instance of speed:

To find the covered distance, use the following formula.

[tex]d=vt[/tex], where "v" is velocity, and "t" is time.

Note. When using this type of formulas, all variables must match units. For example, say that your velocty is on km/hr, this means that the time or distance you input or calculate is going to be on kilometers or hours.

Find the value.

[tex]d=(61(km/h))(10(min))\\ \\d=610 (km).[/tex]

[tex]d=(39(km/h))(20(min))\\ \\d=780 (km).[/tex]

Note. We add up both calculated distances to find the total displacement of the car.

[tex]V(bar)=\frac{td}{ct}\\ \\V(bar)=\frac{610(km)+780(km)}{30(min)}\\ \\V(bar)=46.33(km/hr).[/tex]

The average velocity of the car in Km/h during the trip is 98.37 Km/h

Velocity is simply defined as the rate of change of displacement with time. Mathematically, it can be expressed as:

Velocity = displacement / time

This is the total displacement travelled divided by the total time taken to cover the displacement. Mathematically, it can be expressed as:

Average velocity = Total displacement / total time

Displacement = velocity × time

Displacement = 61 × 0.167

Displacement = 10.187 Km

Average velocity = Total displacement / total time

Average velocity = 49.187 / 0.5

1 The ball travel 58.29 m high

2. The time the ball spend in the air is 8.67 s

The maximum height reached by the ball can be obtained as follow:

v² = u² – 2gh (since the ball is going against gravity)

0² = 33.8² – (2 × 9.8 × h)

0 = 1142.44 – 19.6h

Collect like terms

0 – 1142.44 = –19.6h

–1142.44 = –19.6h

Divide both side by –19.6

h = –1142.44 / –19.6

h = 58.29 m

We'll begin by calculating the time to reach the maximum height . This can be obtained as follow:

v = u – gt (since the ball is going against gravity)

0 = 33.8 – (9.8 × t₁)

0 = 33.8 – 9.8t₁

Collect like terms

0 – 33.8 = –9.8t₁

–33.8 = –9.8t

Divide both side by –9.8

t₁ = –33.8 / –9.8

t₁ = 3.45 s

Next, we shall determine the time take to fall to the ground

h = ½gt²

133.29 = ½ × 9.8 × t₂²

133.29 = 4.9 × t₂²

Divide both side by 4.9

t₂² = 133.29 / 4.9

Take the square root of both side

t₂ = √(133.29 / 4.9)

t₂ = 5.22 s

Finally, we shall determine the time spend by the ball in the air. This is shown below:

T = t₁ + t₂

T = 3.45 + 5.22

A student tosses her sorority sister, who is in a window 2.30 meters above, a set of keys vertically upward.

The second student catches the key 2.50s later.

We simulate the keys as a particle falling at a steady speed. Assume that the positions of the first and second students are, respectively, y(i) = 0 and y(f) = 2.30m.

Now, we have

The time of flight of the keys is t = 2.50 seconds.

Now, the acceleration is a(y) = -9.8 m/s²

We will use the equation of motion,

y(f) = y(i) + v(yi) × t + ( 1/2 ) × a(y) × t²

v(yi) = [ y(f) - y(i) - ( 1/2 ) × a(y) × t² ] / t

v(yi) = [ 2.3 - 0 - ( 1/2 ) × ( - 9.8 ) × (2.5)² ] / 2.50

v(yi) = [ 2.3 + 30.625 ] / 2.50

The accelerating force of the wind on the boat is 707 N northwest and 500 N acting west.

Taking into consideration the wind's accelerating force. It can be visualized as the combination of two elements:

707 /√2 = 500 N acting north, and

707 /√ 2 = 500 N acting east.

It is acting both to the North and to the East because it is supposed to be acting in the Northeast wards. The drag of the keel's eastward component will then cancel out its westward counterpart.

Essentially, 500 N north will then be the result of two forces acting on the boat.

Given that a baseball is hit almost straight up into the air with a speed of 25m/s estimate how high it goes.

At the maximum height, final velocity V = 0

Using third equation of motion, that is, V² = U² - 2gH, we can estimate how high it goes.
