Which equation should be used to calculate the speed of a wave?
speed = frequency x wavelength
speed = frequency x hertz
speed = period x wavelength
speed = period x hertz
The equation should be used to calculate the speed of a wave is speed = frequency x wavelength.
What is the formula for wave speed?The speed of a wave is calculated by the equations: V = λ . f or V = λ/T, and the unit of measurement is m/s. This speed depends on the medium: in gaseous media, the speed is lower than in solid media.

The equation should be used to calculate the speed of a wave is speed = frequency x wavelength.
What is Speed of wave?Wave speed is the movement of a progressive wave, which is an energy-moving disturbance that takes the shape of an oscillation and moves from one place to another.
The wavelength and frequency of a wave both affect its speed. A wave's speed is a crucial factor because it enables us to estimate how quickly the wave will disperse in the medium, which is the substance or material that will carry it.
This is the water in the case of ocean waves and the air in the case of sound waves. The kind of wave and the physical properties of the medium in which it is flowing also affect a wave's velocity.
Therefore, The equation should be used to calculate the speed of a wave is speed = frequency x wavelength.

Romeo traveled by a 900 kg horse from Manitua to Verona accelerating at the rate of 20 km/hr. With what force is Romeo moving at?
Answer:
Force(Romeo moving) = 5,000 N
Explanation:
Given:
Mass of horse = 900 kg
Acceleration = 20 km/hr
Find:
Force(Romeo moving)
Computation:
Acceleration = 20 km/hr
Acceleration in m/s = 20 / 3.6 = 5.555556 m/s²
Force = m x a
Force(Romeo moving) = 900 x 5.555556
Force(Romeo moving) = 5,000 N

a lizard ran 3 meters from his rock to his friend's house. he ran back halfway and stopped. what is his distance traveled
Answer:
4.5m
Explanation:
Distance is the total length of path traveled or covered by a body.
So distance is a scalar quantity, it only has magnitude but no direction.
Therefore:
Total distance = 3 m + [tex]\frac{1}{2}[/tex](3)
So;
3 + 1.5 = 4.5m
Total distance covered 4.5m by the body.

When a power plant sends out high voltage electricity for long distance transmission,
what is needed to make the electricity suable in houses?
•a step down transformer
•a step up transformer
•a generator
•a commutator
Regular wires and cables always have some resistance. So when electric current flows through regular wires and cables, it always loses some energy, It's only a little bit, so we don't usually worry about it.
But if you're the power company, your business is selling electrical energy. If you generate electrical energy at the power plant, and some of it is lost on its way to your customers, then you can't sell the energy that's lost. If you're the power company, then you're shipping ginormous amounts of energy over ginormous distances, and you DO worry about losing any of it.
Strange as it may seem, it turns out that if you ship the electrical energy through the cables at HIGHER voltage, LESS of it gets lost. So the power company wants to send the energy through the cables at the highest-possible voltage. Real power companies use as much as 765 THOUSAND volts to send energy between cities, and 4,800 or 7,200 volts to move it between neighborhoods. (And there's a new long-distance power line in China using 1.1 MILLION volts to move energy a couple thousand miles.)
But this could be a big problem ! You only use 120 volts for most of the things in your house, (or 240 volts for big things like the air conditioner, the stove, or the clothes dryer).
So the power company needs a way to "step down" the voltage from the "transmission line" before they connect the wires into your house.
They use a "step down transformer" to make the electricity suable in houses.
The step-down transformers are the giant square boxes you see on the ground inside the neighborhood power-distribution substation.
And they're the round black cans you see up on the electric poles around the neighborhood.

A car with a mass of 1,400 kg is traveling at a speed of 40 m/s. What is its momentum?
Answer:
56000kgm/s

Sue played four games of golf the modal score was 98 and the mean 100 and the range 10 What were the scores for the games
Answer:
Explanation:
Let the highest and lowest score be a and b respectively .
a - b = 10
a = 10 + b
The numbers in descending order are a , 98 , 98 , b .
mean = 100 , so
4 x 100 = a + 98 + 98 + b = 10 + b + 98 + 98 + b = 206 + 2b
400 = 206 + 2b
2b = 194
b = 97
a = 107
So the scores were as follows
107 , 98 , 98 , 97
