The labeled images each represent the wave patterns found in the electromagnetic wave spectrum.


Which image is correctly labeled for frequency, wavelength, and radiant energy?

Answer: true

because the small truck is going fast and has momentum, so the bus and the truck have the same amount of momentum.

Answer:

1.13 m/s right

Explanation:

Momentum before = momentum after

p₀ = p

p₀ = m₁ v₁ + m₂ v₂

4.9 kg m/s = (5.0 kg) (-0.15 m/s) + (5.0 kg) v

4.9 kg m/s = -0.75 kg m/s + (5.0 kg) v

5.65 kg m/s = (5.0 kg) v

v = 1.13 m/s

Answer: 1.13 m/s equivalent to 1.1 m/s

Answer:

There are [tex]3.779\times 10^{23}[/tex] atoms when the sample of cerium is 20 seconds old.

Explanation:

The decay of isotopes is modelled after the following exponential expression:

[tex]N(t) = N_{o}\cdot e^{-\left(\frac{\ln 2}{t_{1/2}}\right)\cdot t }[/tex] (1)

Where:

[tex]N_{o}[/tex] - Initial number of atoms, dimensionless.

[tex]N(t)[/tex] - Current number of atoms, dimensionless.

[tex]t[/tex] - Time, measured in seconds.

[tex]t_{1/2}[/tex] - Half-time, measured in seconds.

Now we clear the half-time within (1):

[tex]\ln \frac{N(t)}{N_{o}} = -\frac{t\cdot \ln 2}{t_{1/2}}[/tex]

[tex]t_{1/2} = -\frac{t\cdot \ln 2}{\ln \frac{N(t)}{N_{o}} }[/tex]

If we know that [tex]N_{o} = 5\times 10^{23}[/tex], [tex]N(t) = 2\times 10^{23}[/tex] and [tex]t = 66\,s[/tex], then the half-life of the isotope is:

[tex]t_{1/2}=-\frac{(66\,s)\cdot \ln 2}{\ln \frac{2}{5} }[/tex]

[tex]t_{1/2}\approx 49.927\,s[/tex]

And the decay equation for the sample is described by:

[tex]N(t) = (5\times 10^{23})\cdot e^{-0.014\cdot t}[/tex]

Lastly, if we get that [tex]t = 20\,s[/tex], then the activity of the sample of cerium is:

[tex]N(20) = (5\times 10^{23})\cdot e^{(-0.014)\cdot (20)}[/tex]

[tex]N (20) \approx 3.779\times 10^{23}[/tex]

There are [tex]3.779\times 10^{23}[/tex] atoms when the sample of cerium is 20 seconds old.

Answer:

v_{4}= 80.92[m/s] (Heading south)

Explanation:

In order to calculate this problem, we must use the linear moment conservation principle, which tells us that the linear moment is conserved before and after the collision. In this way, we can propose an equation for the solution of the unknown.

ΣPbefore = ΣPafter

where:

P = linear momentum [kg*m/s]

Let's take the southward movement as negative and the northward movement as positive.

[tex]-(m_{1}*v_{1})+(m_{2}*v_{2})=-(m_{1}*v_{3})+(m_{2}*v_{4})[/tex]

where:

m₁ = mass of car 1 = 14650 [kg]

v₁ = velocity of car 1 = 18 [m/s]

m₂ = mass of car 2 = 3825 [kg]

v₂ = velocity of car 2 = 11 [m/s]

v₃ = velocity of car 1 after the collison = 6 [m/s]

v₄ = velocity of car 2 after the collision [m/s]

[tex]-(14650*18)+(3825*11)=(14650*6)-(3825*v_{4})\\v_{4}=80.92[m/s][/tex]

Answer:

delivery truck

Explanation:

All the objects such as delivery truck stopped at a light has no kinetic energy. Thus, the correct option is A.

Kinetic energy is the energy of motion, it is observable as the movement of an object or the subatomic particles of an object. Every moving object and particle have certain amount of kinetic energy. A person who is walking, a soaring baseball, a crumb falling from a table and a charged particle in an electric field are all examples of the kinetic energy at work.

The example in which the delivery truck stopped at a light is an example which has no kinetic energy. Kinetic energy is due to motion of the object.

Therefore, the correct option is A.

The acceleration that the jet liner that must have is 2.241 meters per square second.

Explanation:

Let suppose that the jet liner accelerates uniformly. From statement we know the initial ([tex]v_{o}[/tex]) and final speeds ([tex]v_{f}[/tex]), measured in meters per second, of the aircraft and likewise the runway length ([tex]d[/tex]), measured in meters. The following kinematic equation is used to calculate the minimum acceleration needed ([tex]a[/tex]), measured in meters per square second:

[tex]a = \frac{v_{f}^{2}-v_{o}^{2}}{2\cdot d}[/tex]

If we know that [tex]v_{o} = 0\,\frac{m}{s}[/tex], [tex]v_{f} = 82\,\frac{m}{s}[/tex] and [tex]d = 1500\,m[/tex], then the acceleration that the jet must have is:

[tex]a = \frac{\left(82\,\frac{m}{s} \right)^{2}-\left(0\,\frac{m}{s} \right)^{2}}{2\cdot (1500\,m)}[/tex]

[tex]a = 2.241\,\frac{m}{s^{2}}[/tex]

The acceleration that the jet liner that must have is 2.241 meters per square second.

Four directional arrows with labels five hundred seventy-nine Newtons, four hundred eighty-seven Newtons, five hundred seventy-nine Newtons and six hundred thirty-two Newtons

Answer:

Explanation:

To calculate the time it took the car to hit the ground, we use the formula

speed = distance/time

80 m/s = 300 m/time

time = 300/80

time = 3.75 secs

It must have taken the car 3.75 seconds to hit the ground

To determine the horizontal distance of the car before hitting the ground, the same formula will also be used but with the time obtained above (since that was the time it took before hitting the ground)

speed = distance/time

80 = distance/3.75

distance = 3.75 x 80

distance = 300 meters

Answer:

Balanced forces: When a number of forces acting on a body do not cause any change in its state of rest or of uniform motion along a straight line then the forces are said to be balanced forces. In other words, a body is said to be underbalanced forced when the resulting force acting on the body is zero.

The balanced forces:

⋅ Cannot set any stationary body into motion.

⋅ May change the shape and size of soft objects.

⋅ Cannot change the speed/velocity of a moving body.

Unbalanced forces:

When the resultant of all the forces acting on a body is not zero, then forces are called unbalanced forces.

Example:

⋅ Game of tug of war: When the forces exerted by both the teams are equal, then the rope does not move. But, if the force applied by team A is greater than team B, then the rope, as well as members of the weaker team, i.e., B, will be pulled towards A. The unbalanced force can (a) Set a stationary body in motion.

⋅ Set a moving body at rest.

⋅ Change the direction of motion.
