b. third quarter
c. first quarter
d. full

Answers

Answer 1
Hello,

Here is your answer:

The proper answer to this question is option B "third quarter".

Here is how:

Neap tides are caused when the moon is three thirds full which causes the current to up rise therefore making a neap tide.

Your answer is B.

If you need anymore help feel free to ask me!

Hope this helps!


Answer 2

Answer:

b. third quarter

c. first quarter

Explanation:

Neap tides happen in the third and first quarter of the moon phase, when the moon appears to be half full, this is because of the position of the moon and the gravitational force of the moon attracting the tides along with the gravitational force of the sun, tha causes high tides on new, and full phases, but the third quarter and first quarter, the moon makes a 90º line with the solar gravitational forces, cancelling out both forces making it low tide or neap tide.

A car with a mass of 1,500 kilograms is moving around a circular curve at a uniform velocity of 16 m/s. The curve has a radius of 100 meters. What's the centripetal force on the car?

Answers

Centripetal force can be computed using this formula.

[tex]f = \frac{mv^{2} }{r} [/tex]

where:
f= centripetal force
m = mass
v = velocity
r = radius

Everything you need is already and all you have to do is input it into your formula:
m = 1,500 kg
v = 16m/s
r = 100  m

[tex]f = \frac{(1,500kg)(16m/s)^{2} }{100m} [/tex]
[tex]f = \frac{1,500kg)(256m^{2}/s^{2}) }{100m} [/tex]
[tex]f = \frac{384,000kg.m^{2}/s^{2} }{100m} [/tex]
[tex]f = 3,840 kg.m/s^{2}[/tex] or [tex]f = 3,840 N[/tex]

The centripetal force in a circular motion is given by:
[tex]F_C = m \frac{v^2}{r} [/tex]
where m is the mass of the object, v its speed and r the radius of the circular path.
Using the data of this problem, m=1500 kg, v=16 m/s and r=100 m, and replacing them inside the formula, we find the value of the centripetal force:
[tex]F_C = (1500 kg) \frac{(16 m/s)^2}{100 m}=3840 N [/tex]

C.Wavelengths measured would be longer than the actual wavelengths emitted.

If a star is moving toward us in space, what would we observe about the wavelength from these stars?

A.Wavelengths measured would be shorter than the actual wavelengths emitted.

B.Wavelengths measured would match the actual wavelengths emitted.

C.Wavelengths measured would be longer than the actual wavelengths emitted.

Answers

1) In the first case, the correct answer is
A.Wavelengths measured would match the actual wavelengths emitted.
In fact, the stars are not moving relative to Earth, so there is no shift in the measured wavelength.

2) In this second case, the correct answer is
A.Wavelengths measured would be shorter than the actual wavelengths emitted.
in fact, since the stars in this case are moving towards the Earth, then apparent frequency of their emitted light will be larger than the actual frequency, because of the Doppler effect, according to the formula:
[tex]f'= \frac{c}{c+v_s} f_0 [/tex]
where f0 is the actual frequency, f' the apparent frequency, c the speed of light and vs the velocity of the source (the stars) relative to the obsever (Earth). Vs is negative when the source is moving towards the observer, so the apparent frequency f' is larger than the actual frequency f0. But the wavelength is inversely proportional to the frequency, so the apparent wavelength will be shorter than the actual wavelength.

What’s the force of a pitching machine on a baseball? Baseballs pitched by a machine have a horizontal velocity of 30 meters/second. The machine accelerates the baseball from 0 meters/second to 30 meters/second in 0.5 seconds. If a baseball has a mass of 0.15 kilograms, the force the machine exerts is newtons. Use F = ma, where  .

Answers

The acceleration of the baseball is:
[tex]a= \frac{v_f-v_i}{\Delta t} [/tex]
where [tex]v_f[/tex] and [tex]v_i[/tex] are the final and initial speed of the ball, and [tex]\Delta t[/tex] is the time interval in which the force acted.

Replacing the numbers, we get
[tex]a= \frac{30 m/s-0m/s}{0.5 s}=60 m/s^2 [/tex]
And at this point, we can use Newton's second law F=ma to find the value of the force of the pitching machine:
[tex]F=ma=(0.15 kg)(60 m/s^2)=9 N[/tex]

Answer:

So F=ma

A motorboat, whose speed in still water is 15 km/hour, traveled with the current of a river for 35 km, and against the current for 25 km. the boat took the same time traveling with the current as it did traveling against the current. what is the speed of the current in the river?

Answers

Let's call v=15 km/h the speed of the boat in still water, and c the speed of the current.
When the boat travels with the current, its total speed is (v+c), and it travels for a distance of 35 km in a time t. When the boat travels against the current, its total speed is (v-c), and it travels for a distance of 25 km in the same time t. We can write the basic relationship of the uniform linear motion [tex]S=vt[/tex] for both situations:
[tex]35 km = (v+c)t[/tex]
[tex]25 km=(v-c)t[/tex]
If we divide the first equation by the second one, we find
[tex] \frac{35}{25}= \frac{v+c}{v-c} [/tex]
and by rearranging this, we can find the value of c, the speed of the current:
[tex]c= \frac{1}{6}v= \frac{1}{6}(15 km/h)=2.5 km/h [/tex]

Joan is setting up an experiment in the lab to observe newton's second law of motion. she has a model car that has a mass of 45 kg, and it is accelerating at 7 m/s/s. she then increases the acceleration to 28 m/s/s. what happens to the force of the car?

Answers

The force of the car increases because it is proportional to the acceleration of the object (as stated in the second law). If the object accelerates then the force accelerates, if the acceleration decreases then the force decreases. Same for mass. The force of the car would have changed from 315 newtons of force to 1,260 newtons of force.

In which situation would an object weigh the LEAST? (assume all the objects have the same mass) A) an object on Earth Eliminate B) an object on the moon C) an object half-way between the Earth and moon D) an object in space closer to the moon than the Earth

Answers


D)an object in space closer to the moon than the Earth

Answer: The correct answer is D.      

Explanation:

The object weigh less on the moon than Earth. The weight of the object on the moon is one sixth the weight of the object on the Earth.

Greater the mass of the object, greater will be the gravitational force. Then more will be the weight of the object. The mass of the moon is less than the mass of the earth. The object weigh less on the moon than Earth.

As you go away from the Earth's surface, the weight of the object will get reduce.

An object in space closer to the moon than the earth.

Therefore, an object in space closer to the moon than the Earth would weigh the least.

The cliff divers at acapulco, mexico, jump off a cliff 17.2 m above the ocean. ignoring air resistance, how fast are the divers going when they hit the water?

Answers

The divers are in free fall, and they cover a distance of [tex]S=17.2 m[/tex] in a uniformly accelerated motion, with an acceleration equal to [tex]g=9.81 m/s^2[/tex] (gravitational acceleration). We can find their final velocity vf just before hitting the water using the following relationship
[tex]2aS = v_f^2 -v_i^2[/tex]
where [tex]v_i=0[/tex] is their initial velocity, which is zero because the divers start from rest. Therefore, substituting the numbers we can find vf:
[tex]v_f = \sqrt{2aS}= \sqrt{2\cdot 9.81 m/s^2 \cdot 17.2 m}=18.4 m/s [/tex]

Light with a frequency of 7.18 Ã 1014 hz lies in the violet region of the visible spectrum. what is the wavelength of this frequency of light? answer in units of nm.

Answers

The frequency is 7.18 × 10^14 Hz, c= 3 × 10^8 m/s, where c is the speed of light.
But; c = λf, where λ is the wavelength of the wave and f is the frequency.
Making λ the subject, we get;
λ = c/f
  = (3 ×10^8)/ (7.18 ×10^14)
  = 4.17827 × 10^-7 m
but 1 m = 10^9 nm
Therefore;
 = (4.17827 ×10^-7) × 10^9
 = 417.827 nm
Hence, the wavelength= 417.827 nm

Solving for current (i):
[tex]i = \frac{v}{r} = \frac{1.5}{6} \\ i = 0.25 \: amps[/tex]
A) 0.25 amps

The current in the circuit from the voltage 1.5 V and the resistance 6 ohm is 0.25 ampere. Thus, option A is correct.

What is Ohm's law?

Ohm's law is defined as the current flow in the circuit is directly proportional to the applied voltage in the circuit. Ohm's law is applicable at a constant temperature.

V∝I, where V is the potential difference and I is the current. Ohm's law can also be defined as, V = IR, and R is the resistance of the circuit. The unit of current is ampere(A).

Resistance is defined as the obstruction in current flow and the unit of resistance is ohm(Ω). Resistance is inversely proportional to the current flow. Resistance increases with the decrease of current and vice-versa.

From the given,

Voltage(V) = 1.5 V

Resistance (R) = 6 Ω

Ohm's law, V = IR

V / R = I

I = 1.5 / 6

= 0.25 A

I = 0.25 ampere

Thus, the current flow in the circuit is 0.25 A. Hence, the ideal solution is option A.

A 1.80 m radius playground merry-go-round has a mass of 120 kg and is rotating with an angular velocity of 0.330 rev/s. what is its angular velocity, in rev/s, after a 27.5 kg child gets onto it by grabbing its outer edge? the child is initially at rest.

Answers

Final answer:

To find the final angular velocity of the merry-go-round after the child gets on it, we use the conservation of angular momentum. By setting the initial and final angular momenta equal, we can solve for the final angular velocity. The final angular velocity is found to be approximately 0.301 rev/s.

Explanation:

To find the angular velocity of the merry-go-round after the child gets on it, we need to consider the conservation of angular momentum. The initial angular momentum of the system is equal to the final angular momentum after the child grabs the outer edge. The initial angular momentum of the system is calculated as the product of the moment of inertia of the merry-go-round and its initial angular velocity. The final angular momentum is calculated as the sum of the moment of inertia of the merry-go-round and the child and the final angular velocity.

Let's denote the initial angular velocity of the merry-go-round as ω1, the final angular velocity as ω2, the moment of inertia of the merry-go-round as I1, the moment of inertia of the child as I2, the radius of the merry-go-round as R, the mass of the merry-go-round as M, and the mass of the child as m.

The initial angular momentum is given by:

L1 = I1 * ω1

And the final angular momentum is given by:

L2 = (I1 + I2) * ω2

Setting the initial and final angular momenta equal, we have:

I1 * ω1 = (I1 + I2) * ω2

Rearranging the equation, we can solve for ω2:

ω2 = (I1 * ω1) / (I1 + I2)

Substituting the given values, we have:

ω2 = (120 kg * (1.80 m)^2 * 0.330 rev/s) / ((120 kg * (1.80 m)^2) + (27.5 kg * (1.80 m)^2))

Simplifying the expression, we can calculate the final angular velocity:

ω2 ≈ 0.301 rev/s
