What does it take to be classified as a rouge wave
Answer: A 'rogue wave' is large, unexpected, and dangerous.
At the time, surface winds were light at 15 knots. ... Most reports of extreme storm waves say they look like "walls of water." They are often steep-sided with unusually deep troughs.
Explanation:
Answer:
Rogues, called 'extreme storm waves' by scientists, are those waves which are greater than twice the size of surrounding waves, are very unpredictable, and often come unexpectedly from directions other than prevailing wind and waves.

What kind of energy does an electromagnet use to pick up metallic objects?
Answer:
Magnetic energy is used by an electromagnet to pick up metallic objects
Explanation:
An electromagnet generates its own magnetic field in presence of electric current.
As an electric current is induced in an electromagnet , it magnetic dipole arrange themselves in order to behave as a magnet and hence generate magnetic field with a proper north and south. This leads to attraction of metallic object.
Hence, it can be said that Magnetic energy is used by an electromagnet to pick up metallic objects

Ingrid is correct. The clay appears red because it reflects red wavelengths.
Hence option A is correct.
What is wave ?Wave is is a disturbance in a medium that carries energy as well as momentum . wave is characterized by amplitude, wavelength and phase. Amplitude is the greatest distance that the particles are vibrating. especially a sound or radio wave, moves up and down. Amplitude is a measure of loudness of a sound wave. More amplitude means more loud is the sound wave.
Wavelength is the distance between two points on the wave which are in same phase. Phase is the position of a wave at a point at time t on a waveform.
There are two types of the wave longitudinal wave and transverse wave.
Longitudinal wave : in which, vibration of the medium (particle) is parallel to propagation of the wave. Sound wave is a longitudinal wave. Transverse wave : in which, vibration of the medium (particle) is perpendicular to propagation of the wave. Light wave is a Transverse wave.
Ingrid says that a red ball of clay appears red because the clay reflects red wavelengths. this statement is true.
Hence option A is correct.

Compute the force on each of two electrons when they are seperated in vaccum by a distance corresponding to the approximate size of an ato. (0.100nm)
Answer:
2.304 × 10^-28 N
Explanation:
Compute the force on each of two electrons when they are seperated in vaccum by a distance corresponding to the approximate size of an ato. (0.100nm)
Solution
The formula to use is
F = K Qq / r^2
Substitute all the parameters
F = 9 × 10^9 × (1.6 × 10^-19)^2 / (0.1 × 10^-9)^2
F = 2.304 × 10^-28 / 1 × 10^-10
F = 2.304 × 10^-18 N
Therefore, the force between each of the electron is 2.304 × 10^-18 N
Flossie blew a tire 5 minutes into the second leg, up to that point she had traveled 10 km making her speed 2 km/m. It took 2 minutes to fix her tire. Flossie had to finish within 2 minutes in order to stay even with the evil Mabel. If Flossie had 8 km left what speed will she need to win?
Answer:
4km/m
Explanation:
She was going at 2km/m, so 2 kilometers per minute. She has 2 minutes therefore she needs to double her rate to 4 kilometers per minute.

What happens when a loop of wire turns between two permanent magnets in
a generator?
A. A current flows through the loop of wire.
O B. Electrical energy transforms into mechanical energy.
O C. A current flows through the permanent magnets.
D. Mechanical energy transforms into electromagnetic radiation.
Answer:
B. Electrical energy transforms into mechanical energy.
Explanation:
In the case when the wire loop transforms between the two permanent magnets in a generator so here the electrical energy turns to mechanical energy as there is a working principle behind the generator that the electrical energy would turns into mechanical energy
Therefore as per the given scenario, the option b is correct
And, the rest of the options are wrong

A machine designed to stretch a stiff spring uses 1,550 J of energy to stretch the spring. If the work output is 1,200 J, what is the machine’s efficiency?
Answer:
77%
Explanation:
efficiency= work output/work input X 100%
e = 1,200j/ 1,550 j x100%
e = 1,200/1,550= 0.77
e = 0.77 x 100%
e = 77%

3. A large crane lifts a 25,000 kg mass in the air. The amount of work that must be done by the
crane's lifting components is 2.2 X 10'J (Wo). If the efficiency of the crane is 22%, how much
useful work is done on the mass (Wou)?
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the concept of Efficiency.
Here we can see that, the Input work is given as 2.2 x 10^7 J and the efficiency is given as 22%
The efficiency is => 22% => 22/100.
so we get as,
E = W(output) /W(input)
hence, W(output) = E x W(input)
so we get as,
W(output) = (22/100) x 2.2 x 10^7
=> W(output) = 0.22 x 2.2 x 10^7 => 0.484 x 10^7
hence, W(output) = 4.84 x 10^6 J
The useful work done on the mass is 4.84 x 10^6 J
