E- what will be the total charge of the compound formed?

F what type of band will form?

Answer:

Explanation:

An impulse results in a change of momentum

FΔt = mΔV

m = FΔt / ΔV

m = F(t₁ - t₀) / (v₁ - v₀)

If the initial flight direction is the positive direction

m = -19.0(1.20 - 0.00) / (-7.00 - 5.00)

m = 1.9 kg

Explanation:

klljl

By Newton's second law, the net force exerted on the object makes it undergo an acceleration a such that

(2 kg) a = 5 N

so that it is accelerated a = 2.5 m/s^2.

Since the object starts with velocity 3 m/s, after 7 s its acceleration will make it speed up to

3 m/s + (2.5 m/s^2) (7 s) = 20.5 m/s

The center mass of the car from the front for the given passengers is 3.46 m.

The given parameters;

Assuming the mass of the passengers is the same, let their mass = m

Keeping the front seat as the reference point, the center mass is calculated as;

[tex]X_{cm} = \frac{ \ 2M(2.8m) \ + \ 3M(3.9m) }{2M + 3M} \\\\X_{cm} = \frac{17.3 Mm}{5M} \\\\X_{cm} = 3.46\ m[/tex]

Thus, the center mass of the car from the front for the given passengers is 3.46 m.

Answer:

31.3 km/h

Explanation:

momentum before collison = momentum after collion

m1xv1 = m2xv2

25x  1500 = 1200 x v2

v2=32.25 km/h = 32.3 km/h (3 sf)

The lighter car is moving at 6.25 km/h South after the collision.

The law of conservation of momentum asserts that, unless an external force is applied, the total momentum of two or more bodies operating upon one another in an isolated system remains constant. As a result, momentum cannot be gained or lost.

Newton's third law of motion has a direct impact on the idea of momentum conservation.

From law of conservation of momentum; we can write:

Total initial momentum = total final momentum

1500 kg × 100 km/h + 1200×(-100 km/h) = 1500 kg × 25.0km/h + 1200×(v km/h)

100×300 kg-km/h = 1500×25 kg-km/h +  1200×(v kg-km/h)

1200×(v kg-km/h) = -7500

v = - 6.25 km/h.

Hence,  the lighter car is moving at 6.25 km/h South after the collision.

There are many forms of energy transformation, the main being:

+ GPE (Gravitational Potential Energy)

+ Chemical Energy

+ Electrical Energy

+ Radiant Energy

+ Kinetic Energy.

+ Mechanical Energy

For this case, the gasoline has to power a motor in most cases to turn the wheels of the automobile, the gasoline is burnt to create energy to power the motor(s).

In this case, the motor is moved due to Mechanical Energy.

(Keep in mind that Gasoline isn't energy, although it's used to create energy.)

Answer:

f = c / y          where y is the wavelength lambda

y = 3.00E8 / 5.17E14/s = 5.80E-7 m = 580 millimicrons - visible yellow

To calculate the wavelength of the radiation, you can use the formula that relates the speed of light (c) to the frequency (f) and wavelength (λ) of electromagnetic waves: λ = c / f.

Where:

λ = Wavelength

c = Speed of light (approximately 3.00 x 10^8 m/s)

f = Frequency

Given that the frequency (f) is 5.17 x 10^14 s^-1, you can plug in the values and calculate the wavelength:

λ = (3.00 x 10^8 m/s) / (5.17 x 10^14 s^-1)

λ ≈ 5.80 x 10^-7 meters

So, the wavelength of the radiation is approximately 5.80 x 10^-7 meters, which is in the range of the visible light spectrum (typically measured in nanometers).

The energies that the ball possess when it is in rest at the top of the hill is electrostatic  potential energy. When the ball at the level ground, it has gravitational potential energy and when it at the half way down hill , it possess rotational kinetic energy.

Potential energy of a body is generated by virtue of its position. When the object is placed at rest on the surface the gravitational field, the stored energy is called gravitational potential energy.

When the object starts to move it gains kinetic energy.  When the ball is at rest on the top of the hill it has the electrostatic potential energy. When starts to roll to the ground , then its potential energy converts to rotational kinetic energy.

When, the ball reaches the ground its kinetic energy again transforms to potential energy where the ball is falling down to the gravitational field and thus it possess gravitational potential energy.

I. The resistance which is needed to generate a current of 0.25 Ampere in the ceiling fan is 480 Ohms.

II. Since current is inversely proportional to the resistance in the electrical circuit, an increase in the current (larger currents) flowing into the electrical circuit of the ceiling fan would cause the resistance to decrease in magnitude at medium and high speeds.

Given the following data:

To calculate the resistance needed to generate that current, we would apply Ohm's law:

Ohm's law states that at constant temperature, the current flowing through an electrical circuit is directly proportional to the voltage (potential difference) applied across the two terminals of the electrical circuit and inversely proportional to the resistance in the electrical circuit.

Mathematically, Ohm's law is given by the formula;

[tex]V=IR[/tex]

Where;

Making R the subject of formula, we have:

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

Substituting the given parameters into the formula, we have;

[tex]R=\frac{120}{0.25}[/tex]

Resistance, R = 480 Ohms

Since current is inversely proportional to the resistance in the electrical circuit, an increase in the current (larger currents) flowing into the electrical circuit of the ceiling fan would cause the resistance to decrease in magnitude at medium and high speeds.

In conclusion, the larger the current, the lower the resistance would be at both medium and high speeds.

50 km/h east is an example of velocity.

When an item is moving, its velocity is the rate at which its direction is changing as seen from a certain point of view and as measured by a specific unit of time. Uniform motion an object is said to have uniform motion when object cover equal distance in equal interval of time within exact fixed direction. For a body in uniform motion, the magnitude of its velocity remains constant over time.

Velocity is direction and magnitude and so 50 km/h east is an example of velocity.

[tex]\boxed {\boxed {\sf 4.5 \ m/s \ in \ the \ positive \ direction}}[/tex]

Explanation:

We are asked to find the final velocity of the boat.

We are given the initial velocity, acceleration, and time. Therefore, we will use the following kinematic equation.

[tex]v_f= v_i + at[/tex]

The initial velocity is 2.7 meters per second. The acceleration is 0.15 meters per second squared. The time is 12 seconds.

Substitute the values into the formula.

[tex]v_f = 2.7 \ m/s + (0.15 \ m/s^2)(12 \ s)[/tex]

Multiply the numbers in parentheses.

[tex]v_f= 2.7 \ m/s + (0.15 \ m/s/s * 12 \ s)[/tex]

[tex]v_f = 2.7 \ m/s + (0.15 \ m/s *12)[/tex]

[tex]\v_f=2.7 \ m/s + (1.8 \ m/s)[/tex][tex]v_f=2.7 \ m/s + (1.8 \ m/s)[/tex]

Add.

[tex]v_f=4.5 \ m/s[/tex]

The final velocity of the boat is 4.5 meters per second in the positive direction.
