Answer:
v = 31.89 m/s
Explanation:
p = m × v
1,850 = 58 × v
58v = 1,850
v = 1,850/58
v = 31.89 m/s

What is the velocity of a wave with a frequency of 300 Hz and a wavelength of 0.45 m?
Answer:
velocity= 135m/s
Explanation:
velocity = 300×0.45
= 135m/s²
a cycle lasts for 8 seconds. what is the frequency
This frequency definition leads us to the simplest frequency formula: f = 1 / T . f denotes frequency and T stands for the time it takes to complete one wave cycle measured in seconds. The SI frequency unit is Hertz (Hz), which equals 1/s (one cycle per second)

Select the correct sequence of steps for lighting a Bunsen burner?
A. Apply the spark above the barrel of the Bunsen burner.
B. Open the gas adjustment at the base of the Bunsen burner.
C. Connect the burner hose to the gas outlet.
D. Open the gas valve on the gas outlet
D. C, A, B
C, A, D, B
C, D, A, B
C, D, B, A
Answer:
CDBA
Explanation:
Just did it on Study island
The correct sequence of steps for lighting a Bunsen burner would be C, D, B, A, therefore the correct answer is option D.
What is thermal energy?Thermal energy sometimes referred to as heat energy, may be described as the type of energy in which heat is transmitted from one body to another body as a result of their molecular motions.
The following would be the proper procedure for lighting a Bunsen burner:
Link the gas outlet and the burner hose.
The gas output valve should be opened.
Open the Bunsen burner's base-mounted gas adjustment valve.
The Bunsen burner's barrel should be covered with the spark.
Thus, the right response is option D since the proper stages to ignite a Bunsen burner are C, D, B, and A.

A 3000 kg truck travelling at 50km/hr strikes a stationary 1000 kg car, locking the two vehicles
together. What is the final velocity of the two vehicles?
(Please show work)
Answer:
50 x 3000 = 150000/4000 = 37.5
37.5 I think.
Explanation:
Hope this helps!
A 3000 kg truck travelling at 50km/hr strikes a stationary 1000 kg car, locking the two vehicles together, the final velocity of the two vehicles after the collision is approximately 10.43 m/s.
We may use the concept of conservation of momentum to calculate the final velocity of the two vehicles after the collision.
The total initial momentum (P_initial) is given by:
P_initial = (mass of truck) * (initial velocity of truck) + (mass of car) * (initial velocity of car)
P_initial = (3000) * (50) + (1000) * (0)
The velocity:
Vt = 50 * (1000/3600) = 13.9 m/s
Vc = 0 = 0 m/s
P_initial = (3000) * (13.9) + (1000) * (0 )
P_initial = 41700 kg·m/s
P_initial = P_final
41700 kg·m/s = (3000 kg + 1000 kg) * Vf
41700 kg·m/s = 4000 kg * Vf
Now Vf:
Vf = 41700 kg·m/s / 4000 kg
Vf ≈ 10.43 m/s
Therefore, the final velocity of the two vehicles after the collision is approximately 10.43 m/s.

what is the formula for acceleration?
Answer:
Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.

Use what you have learned in the reading to answer the following question. The point of a compass needle points to Earth’s north pole. The point in the compass needle has–
~the same polarity as Earth's north pole.
~the opposite polarity from Earth’s north pole.
~no polarity.
~unlimited polarity.
The point in the compass needle has the opposite polarity from Earth’s north pole. The correct option is B.
What is a compass needle?The compass needle A magnetized pointer within a compass that can freely align with the Earth's magnetic field.
The magnetic needle is the most important part of the compass. It swings around the compass as you move, but the red end always points north and the white (or sometimes black) end always points south.
If you mean the geographical North Pole, the needle would point south because that is the only way to get there; more specifically, it would point south along the 112.4 degrees west longitude meridian towards the magnetic north pole at 82 degrees north, where compasses point.
Thus, the correct option is B.

Ranjana has average velocity 3.2 m/s
How long does she take to cover a displacement
of 256 m
Answer:
t= 80 seonds
Explanation:
Given that,
The average velocity of Ranjana, v = 3.2 m/s
We need to find how long does she take to cover a displacement of 256 m. Let she takes t time.
We know that,
Average speed = distance/time
So,
[tex]t=\dfrac{d}{v}\\\\t=\dfrac{256\ m}{3.2\ m/s}\\\\t=80\ s[/tex]
So, she will take 80 seconds to cover a displacement of 256 m.
An object initially traveling at 20.0 m/s south decelerates uniformly at 6.00 m/s2 and is displaced 25.0 m. What is the final velocity of the object? (magnitude and direction)

A meterologist made these observations one day:
• In the morning, anocean wave hit a shoreline every 15 seconds.
• In the afternoon, an ocean wave hit the shorlinie every 30 seconds.
Identify whether the ocean waves transferred more or less energy in the morning than in the afternoon.
Write your answer in complete sentences.
Answer:
They transfered more energy in the morning.
Explanation:
This is because, let me put this in simple words, you have more energy, you can run more laps around the track, right? This is the same with the waves. They have more energy, so they can crash aganst the shore more!
