if two such generic humans each carried 2.5 c coulomb of excess charge, one positive and one negative, how far apart would they have to be for the electric attraction between them to equal their 600 n weight?

Answer:

The velocity component in south direction is 42.42 miles/hour and in west direction is 42.42 miles/hour.

Explanation:

Given that,

Speed = 60 miles/hour

Direction = south west

Let the south in y axis and west in x axis.

Angle between x and y will be θ.

The component of speed is [tex]V_{x}[/tex] of x axis and  [tex]V_{y}[/tex] of y axis.

[tex]\vect{V}=\vec{V_{x}i}+\vec{V_{y}j}[/tex]

Where,

[tex]V_{x}=|\vec{V}|\cos\theta[/tex]...(I)

[tex]V_{y}=|\vec{V}|\sin\theta[/tex]....(II)

We know that,

The south west direction makes 45° with west direction in x axis.

(a). We need to calculate the velocity component in south direction

Using equation (I)

[tex]V_{x}=|\vec{V}|\cos\theta[/tex]

Put the value into the formula

[tex]V_{x}=60\times\cos45[/tex]

[tex]V_{x}=42.42\ miles/hour[/tex]

(b). We need to calculate the velocity component in west direction

Using equation (II)

[tex]V_{x}=|\vec{V}|\sin\theta[/tex]

Put the value into the formula

[tex]V_{x}=60\times\sin45[/tex]

[tex]V_{x}=42.42\ miles/hour[/tex]

Hence, The velocity component in south direction is 42.42 miles/hour and in west direction is 42.42 miles/hour.

Considering the Ohm's law, the voltage of a circuit with 15 amps (bedroom) of current and a bedroom light with 12 ohms of resistance is 180 volts.

Current is the physical quantity that expresses the amount of electricity that flows through a conductor in the unit of time and is measured in amperes

The voltage is the difference that exists between the electrical charge that leaves the source and with which it finally reaches the end of the circuit. It is expressed in volts.

Resistance is the difficulty that a circuit opposes to the passage of a current. They are measured in ohms.

Ohm's law establishes the relationship between current, voltage, and resistance in an electrical circuit. This law establishes that the current through a circuit is directly proportional to its voltage or voltage and inversely proportional to the resistance it presents.

Mathematically Ohm's law is expressed as:

[tex]I=\frac{V}{R}[/tex]

Where I is the intensity that is measured in amps (A), V the voltage that is measured in volts (V); and R is the resistance measured in ohms (Ω).

In this case, you know:

Replacing in Ohm's law:

[tex]15 amps=\frac{V}{12 ohms}[/tex]

Solving:

V=  15 amps× 12 ohms

V=180 volts

In summary, the voltage of a circuit with 15 amps (bedroom) of current and a bedroom light with 12 ohms of resistance is 180 volts.

Answer:

The net force that acts on the sailboat has a magnitude of 217 N and is applied at an angle of 64° north of east.

Explanation:

Mechanical Force

The second Newton's law states the net force exerted by an external agent on an object of mass m is:

[tex]\vec F = m.\vec a[/tex]

Where [tex]\vec a[/tex] is the acceleration of the object. Note both the force and the acceleration are vectors. The relationship between them is the mass, a scalar.

This means the net force and the acceleration have the same direction.

The sailboat has a mass m= 350 Kg and moves at a=0.62 m/s^2. The magnitude of the net force acting on the boat is:

[tex]F=0.62 * 350=217\ N[/tex]

As stated above its direction is the same as the acceleration, thus:

The net force that acts on the sailboat has a magnitude of 217 N and is applied at an angle of 64° north of east.

The net force that acts on the sailboat has a magnitude of 217 N and is applied at an angle of 64° north of east.

Here this law of motion should be applied

We know that

F = ma

Here m means the mass

And, the a means the acceleration

Since m is 350 kg

And, a is 0.62

so the net force should be

= 350 * 0.62

= 217 N

Also the direction should be the same

hence, The net force that acts on the sailboat has a magnitude of 217 N and is applied at an angle of 64° north of east.

Answer:

F = 13252.46 [N]

Explanation:

To solve these types of problems we must make a free body diagram. Attached we cand find a diagram of this free body diagram with the forces acting on the truck, since the truck does not move it follows that it is in static equilibrium so the sum of the forces on the X and Y axes must be equal to zero.

In the free body diagram it is necessary to use a Force F, which prevents the truck from going downhill, the direction of this force must be opposite to the movement towards the downhill.

Thus performing a sum of forces on the X-axis equal to zero, we can find the Force F corresponding to the brakes of the truck.

Explanation:

[tex]{\displaystyle {\overline {a}}={\frac {\Delta v}{t}}}[/tex]

You need to use the acceleration formula. A is acceliration, [tex]\displaystyle \Delta \mathbf {v}[/tex] is change in velocity and t is time.

You  need to multiply the formula with t and divide by a and you get

a*t=[tex]\displaystyle \Delta \mathbf {v}[/tex]

t= [tex]\displaystyle \Delta \mathbf {v}[/tex]/a

after that you just need to insert the numbers

change in velocity is 76.4 minus 0.

acceliration is gravitational acceleration which is 9.81.

After that you get

t=76.4/9.81

Answer:19

Explanation:

The equation which correctly relates mechanical energy, thermal energy and total of energy when there is friction is E total = ME + E thermal.

This is the force which resists the relative motion of an object and it produces thermal energy.

This is why the appropriate equation is denoted as the sum of the mechanical energy and thermal(heat energy).

E total = Mechanical energy + E thermal.

Answer:

density = 5000 [kg/m^3]

Explanation:

Density is defined as the relationship between mass and volume.

Now we have:

m = 100 [gr] = 0.1[kg]

V = volume = 20[cm^3]

[tex]20[cm^{3}]*1[\frac{m^{3} }{100^{3} cm^{3} } ] = 2*10^{-5}[m^{3} ][/tex]

density = 0.1 / (2 x 10^-5)

density = 5000 [kg/m^3]

Answer:5

Explanation:

Answer:

x = 125 [m]

Explanation:

To solve this problem we must use the following kinematics equations.

[tex]v_{f} = v_{i} - (a*t)[/tex]

where:

Vf = final velocity = 0

Vi = initial velocity = 10 [m/s]

t  = time = 25 [s]

a = acceleration [m/s2]

Note: the negative sign of the last term of the equation means that the speed decreases, that is, the body slows down.

Now replacing:

0 = 10 - (a*25)

a = 0.4 [m/s^2]

Now we must find the displacement value with the following equation and with the acceleration value found.

[tex]v_{f} ^{2} = v_{i} ^{2}-(2*a*x)[/tex]

where:

x = displacement [m]

(10)^2 = 2*0.4*x

x = 125 [m]
