Answer:
La Niña, because the jet stream is displaced northwards
Explanation:
La Nina is known to be a cool phase that affects the average ocean temperature. During this period the surface wind becomes stronger and there is lesser rainfall over the areas of the central tropical Pacific to which the Southern United States belongs.
Hence, when the southern United States experiences periodic occurrences of severe cold and drought conditions, the weather phenomenon most likely causes this and why is "La Niña, because the jet stream is displaced northwards."

can a body have zero velocity and finite acceleration?Explain
Answer:
Kinda? Depends what the question is fully asking
Explanation:
Acceleration is a change in velocity. So I guess if the velocity of something is -2 m/s and its positively accelerating at a value of +1 m/s, then that means every second its velocity changes by +1m/s.
So that -2 m/s thing after one second will be going -1 m/s.
After another second it'll be going 0 m/s.
After another itll be going +1 m/s and so on.
So at one point for a brief moment, it can have an acceleration but be at 0 m/s velocity.

1. In a demonstration, Mr. K stretches a steel wire to a length 1.23 meters and braces both ends so that they are not free to vibrate. He attaches a fancy piece of equipment which he calls a mechanical oscillator to the wire and explains how it works. Then Mr. K turns the oscillator on and tunes the frequency to 588 Hz. To the amazement of the class, the wire begins vibrating in the sixth harmonic wave pattern. a. Determine the speed of waves within the wire. b. Determine the frequency at which the wire will vibrate with the first harmonic wave pattern. c. Determine the frequency at which the wire will vibrate with the second harmonic wave pattern.
Answer:
a.241.08 m/s b. 196 Hz c. 392 Hz
Explanation:
a. Determine the speed of waves within the wire.
The frequency of oscillation of the wave in the string, f = nv/2L where n = harmonic number, v = speed of wave in string, L = length of string = 1.23 m.
Since f = 588 Hz which is the 6 th harmonic, n = 6. So, making v subject of the formula, we have
v = 2Lf/n
substituting the values of the variables into v. we have
v = 2 × 1.23 m × 588Hz/6
v = 241.08 m/s
b. Determine the frequency at which the wire will vibrate with the first harmonic wave pattern.
The first harmonic is obtained from f when n = 1,
So, f = v/2L = 241.08 m/s ÷ 1.23m = 196 Hz
c. Determine the frequency at which the wire will vibrate with the second harmonic wave pattern.
The second harmonic f' = 2f = 2 × 196 Hz = 392 Hz

An object falls from a height of 12m. The object's potential energy at the top is 50J. Where is the potential energy of the object
25J
Answer:
the height of the is 6 m.
Explanation:
Given;
potential energy of the object, P.E = 50 J
Height of fall of the object, H = 12 m
Determine the mass of the object, m
P.E = mgh
m = (P.E) / (gh)
m = (50) / (9.8 x 12)
m = 0.425 kg
Let the height of the object at 25 J = h₂
mgh₂ = 25
h₂ = (25) / (mg)
h₂ = (25) / (0.425 x 9.8)
h₂ = 6 m
Therefore, the height of the object at 25 J is 6 m.
Matt has a portable basketball goal in his driveway. He has the basket set 8 ft (2.4 m) high so he can practice dunking the ball. He slams the ball through the hoop and then hangs onto the rim. This exerts a downward force of 600 N on the front of the rim. The front of the rim is 1.1 m in front of the front edge of the portable basketball goal%u2019s base. The mass of the whole portable basketball goal is 70 kg. The center of gravity of the portable basketball goal is 1.0 m behind the front edge of its base.
a. How much torque is produced around the front of the goal base by the 600 N force Matt exerts on the front of the rim?
b. How much torque would be needed to tip the goal?
c. What is the largest vertical force that can be exerted on the front edge of the rim before the portable basketball goal begins to tip?
Answer:
a) τ₁ = 660 N m, b) τ’= 686 N m, c) F = 623.6 N
Explanation:
a) For this exercise let's use the concepts of torque and rotational balance.
For this we set a reference system at the base and assuming that the counterclockwise rotations are positive
where the force F = 600 N, the distance to the axis is x = 1.1 m, the mass of the system m = 70g and the weight is placed at the point of the center of gravity x_{cm} = -1.0 m
The torque at the front is
τ₁ = F x
τ₁ = 600 1.1
τ₁ = 660 N m
b) let's write the rotational equilibrium condition
∑ τ = 0
τ'- W x_{cm} = 0
τ ’= mg x_{cm}
τ’= 70 9.8 1.0
τ’= 686 N m
c) the greatest force Matt can apply
τ’= F x
F = τ’/ x
F = 686 / 1.1
F = 623.6 N

When an object is moving to the left and slowing down, what direction is the acceleration?
Answer:
According to our principle, when an object is slowing down, the acceleration is in the opposite direction as the velocity. Thus, this object has a negative acceleration. In Example D, the object is moving in the negative direction (i.e., has a negative velocity) and is speeding up.

Which group number below represents the Oxygen Group?
1 point
18
Periodic Table of the Elements
14
15
2
18
16
Oxygen has an atomic number 8, because it has 8 protons and 8 electrons.
The first shell of an atom can hold up to 2 electrons but oxygen has 8 electrons, in that eight electrons 2 are in the first shell, so it has 6 more electrons left. The second shell can hold up to 8 electrons, oxygen has only 6 more electrons after the first shell is full, so it will have 6 electrons in the second shell
From this we know that oxygen has 2 shells so it is in period 2, and by counting from left to right, the sixth box in period 2 lies on group 16
Therefore Oxygen lies on group 16 and period 2

A 10 ohms resistor, 10 mh inductor, and 10micro farad capacitor are connected in series with a 10khz voltage source. The rms current through the circuit is 0.20A. Find the rms voltage drop across each of the three elements
Answer:
126 V
Explanation:
The computation of the rms voltage is shown below:
= I × R
=(.2) × (10)
= 2 V voltage drop across capacitor
= I × 1 ÷ (?C)
= I ÷ (2 × pi × f × C)
= (.2) ÷ (2 × pi × 10,000 × 10 × 10^-6)
= .318 V voltage drop across inductor
= I × ?L
= I × 2 × pi × f × L
= .2 × 2 × pi × 10,000 × .010
= 126 V

Explanation:
A small difference between means may not be statistically significant, but it could reach statistical significance with a large sample becausea) As N increases, the standard error gets smaller, reflecting less variability in sample means, which allows greater sensitivity to detect small but significant differences.b) As N increases, distributions get more heterogeneous, allowing small differences to be detected.c) The overlap between distributions grows as sample size increases.d) The difference between means gets larger as sample size increases
Answer:
Increasing the sample size could make a small difference between means reach statistical significance because;
a) As N increases the standard error gets smaller reflecting less variability in sample means, which allows greater sensitivity to detect small but significant differences
Explanation:
The p-value of a test statistic is used to express the level of significance of the test result. A significant result is typically considered as one with a small p-value of less than or equal to 0.05 at which point we reject the null hypothesis
The p-value can be made smaller by either
1) Increasing the size of the sample (N)
2) Decreasing the standard error
3) Increasing the difference between the hypothesized parameter and the statistic of the sample
The standard error, SE, is given as follows;
[tex]SE = \dfrac{\sigma}{\sqrt{N} }[/tex]
Where;
σ = The standard deviation of the sample
n = The sample size
Therefore the standard error decreases, gets smaller, with increasing sample size, N
Therefore, the small difference between the sample mean could reach statistical significance with a large sample because as N increases the standard error gets smaller reflecting less variability in sample means, which allows greater sensitivity to detect small but significant differences.
When a light ray is reflected from a surface, the ratio of the angle of incidence to the angle of reflection is
Answer:
equal to 1
Explanation:
When any ray of light falls or strikes on a surface, the ray is reflected back and the angle of reflection is equal to angle of the incidence, where both the angles are always measured from the path of light that is normal to surface of the point at which the ray of light strikes the surface. This is called as the laws of reflection of light.
And therefore, the ratio of the angle of incidence to the angle of reflection is always equal to 1.

The height of a helicopter above the ground is given by h = 3.0 t^2, where h is in meters and t is in seconds. After 5.0 s, the helicopter releases a small mailbag. How long after its release does the mailbag Preach the ground
Answer:
3.91 s
Explanation:
From the question,
The height of the helicopter is given as
h = 3t²......................... Equation 1
After 5 seconds, The height of the helicopter is given as
h = 3(5²)
h = 3×25
h = 75 m.
Note: The small mailbag falls under gravity.
Hence,
h = ut + 1/2(gt²)....................... Equation 2
Where u = initial velocity of the mailbag, t = time, h = height, g = acceleration due to gravity of the mail bag.
Given: h = 75 m, u = 0 m/s ( at the maximum height).
Constant: g = 9.8 m/s²
Substitute these values into equation 2
75 = 0(t) +1/2(9.8t²)
solve for t
1/2(9.8t²) = 75
4.9t² = 75
t² = 75/4.9
t² = 15.31
t = [tex]\sqrt{15.31}[/tex]
t = 3.91 s
