Explanation:

i had the same quiz today and the other 2 are wrong

Answer:

3.29 meters

Explanation:

c = λ f

c = speed of light = 3 * 10^8 m/s

λ = wavelength

f = frequency

3 * 10^8 m/s = λ * (9.13 * 10^7 1/s)

λ  = (3 * 10^8 m/s) / (9.13 * 10^7 1/s)

λ  = 3.29 m

Explanation:

the switch and the battery

Answer:B

Explanation:

Because chemical energy fuels your body with energy so without it u wont have enough energy to move.

Answer:

Studies show that eating fewer animal-based products could reduce water use since animal production uses more water than crops do. In addition, reducing the amount of food that's lost or wasted at various points in the food supply chain could feed about 1 billion extra people while simultaneously reducing water use.

Answer:

A) rational kinetic energy is conserved

For the scenario painted below Rational kinetic energy is conserved

Option A is correct

Kinetic energy is simply defined as the energy that an item or particle has as a result of its movement.

Answer:

Centrifugal force = 1230.77 Newton.

Explanation:

The force associated with the car is generally referred to as centrifugal force and it can be calculated using the formula;

Centrifugal force = mv²/r

Given the following data;

Mass = 800kg

Radius = 65m

Velocity = 10m/s

To find the force;

Centrifugal force = (800*10²)/65

Centrifugal force = (800*100)/65

Centrifugal force = 80000/65

Centrifugal force = 1230.77 Newton.

A hanging 7.5 kg object stretches a spring 1.1 m, the spring constant of the spring is approximately 66.82 N/m.

Hooke's Law, which states that the force exerted by a spring is directly proportional to the displacement of the spring from its equilibrium position, can be used to compute the spring constant.

F = -k * x

Here, we have:

mass (m) = 7.5 kg,

displacement (x) = 1.1 m,

acceleration due to gravity (g) = 9.8 m/[tex]s^2[/tex].

We know that:

weight (W) = mass * acceleration due to gravity

So,

W = m * g

W = 7.5 kg * 9.8 m/[tex]s^2[/tex]

W = 73.5 N

F = W = 73.5 N

F = -k * x

73.5 N = -k * 1.1 m

Solving for k:

k = -73.5 N / 1.1 m

k ≈ 66.82 N/m

Thus, the spring constant of the spring is approximately 66.82 N/m.

Answer:

If a coil of wire is placed in a changing magnetic field, a current will be induced in the wire. This current flows because something is producing an electric field that forces the charges around the wire. (It cannot be the magnetic force since the charges are not initially moving). ... that determines the induced current.

Answer:

The Forces of Flight

At any given time, there are four forces acting upon an aircraft.  

These forces are lift, weight (or gravity), drag and thrust. Lift is  

the key aerodynamic force that keeps objects in the air. It is the  

force that opposes weight; thus, lift helps to keep an aircraft in  

the air. Weight is the force that works vertically by pulling all  

objects, including aircraft, toward the center of the Earth. In order  

to fly an aircraft, something (lift) needs to press it in the opposite  

direction of gravity. The weight of an object controls how strong  

the pressure (lift) will need to be. Lift is that pressure. Drag is a  

mechanical force generated by the interaction and contract of a  

solid body, such as an airplane, with a fluid (liquid or gas). Finally,  

the thrust is the force that is generated by the engines of an  

aircraft in order for the aircraft to move forward.

Answer:

Impulse = 4Ns

Explanation:

Given the following data;

Force = 2N

Time = 2 seconds

To find the impulse experienced by the object;

Impulse = force * time

Impulse = 2*2

Impulse = 4Ns

Therefore, the impulse experienced by the object is 4 Newton-seconds.

Explanation:

When a parallel beam of light passes through a convex lens, the rays become farther from one another when the come out. This process of rays is called ''to diverge''. The concave lens makes rays of light diverge, so it is called diverging lens.

Explanation:

Given that,

The wavelength of light = 580 nm

Slit separation, d = 0.000125 m

We need to find the angle of the third dark interference. For the dark fringe,

[tex]d\sin\theta=(m+\dfrac{1}{2})\lambda[/tex]

Put m = 3 and other values also.

[tex]d\sin\theta=(3+\dfrac{1}{2})\lambda\\\\d\sin\theta=\dfrac{7\lambda}{2}\\\\\sin\theta=\dfrac{7\lambda}{2d}\\\\\theta=\sin^{-1}(\dfrac{7\lambda}{2d})\\\\\theta=\sin^{-1}(\dfrac{7\times 580\times 10^{-9}}{2\times 0.000125 })\\\\\theta=0.93^\circ}[/tex]

So, the angle is 0.93°.

Answer: 0.665 deg

Explanation:

m=3

lambda= 580

d (converted to nanometers)= 125000

Using the equation of angle=arcsine of m-1/2 times lambda divided by d, filled in it would be arcsine of 3-1/2 times 580 over 125000.

Answer:

to find the slope you need to find the change in distance then you divide by the corresponding change in time

eg
