Answer:
A lower frequency and a longer wavelength is correct on edge 2021
please thank the person above me though, they deserve it.
These snakes can sense electromagnetic waves that have a lower frequency and a longer wavelength.
How do snakes detect?With almost ineffective hearing and vision, snakes can be extremely fast animals. Snakes can use chemoreceptors, heat, and even their tails to recognize prey and mates. With mostly ineffective hearing and vision systems, snakes can be extremely fast animals.
They also “see” in infrared. Thanks to the mechanism, they can track prey up to a meter away by the heat of their bodies. They use a simple organ, the loreal pit, located near the nostrils.

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
You measure my life in hours and I serve you by expiring. I’m quick when I’m thin and slow when I’m fat. The wind is my enemy.
This is so hard.
The measure of life in hours and wind is my enemy states that is a candle as it states I serve you by expiring.
What is a candle ?A candle is a stick made of wax and forms an inflammable solid substance. It has a light and gives some sort of fragrance.
It can also provide a medium to heat or to save time, as the candle is burnt the oxygen is consumed and carbon id is given out. As the statement speaks about the wind which is my enemy, it states the nature of the candle that dies out immediately.

Group of answer choices
It measure the effort it takes for an object to move
IT measures the change in an object speed
It measures how quickly an object moves
No answer text provided.
Answer:
It measure the effort it takes for an object to move
Explanation:
Work done is the force applied to move a body through a particular distance.
It can also to be said to be a measure of the effort it takes for an object to move.
The unit of work done is in Joules.
To find work done, we use the expression below:
Work done = Force x distance

A ball rolls with a speed of 3 m/s across a level table that is 1.5m above the floor. How far along the floor is the landing spot from the table?
Answer:
d = 1.65 m
Explanation:
Given that,
The speed of a ball, v = 3 m/s
A ball rolls a level table that is 1.5 m above the floor.
We can find how long the ball is in free fall. We can use the second equation of kinematics as follows :
[tex]s=ut+\dfrac{1}{2}gt^2[/tex]
u is the initial speed in the vertical direction
So,
[tex]s=\dfrac{1}{2}gt^2\\\\t=\sqrt{\dfrac{2s}{g}} \\\\t=\sqrt{\dfrac{2\times 1.5}{9.8}} \\\\t=0.55\ s[/tex]
Now, using the formula of velocity.
[tex]v=\dfrac{d}{t}\\\\d=vt\\\\d=3\times 0.55\\\\d=1.65\ m[/tex]
So, the landing spot is at 1.65 m from the table.
