Answer: Wavelength is the length of one complete wave cycle (Option C)

Explanation:

Wavelength is the distance between two consecutive crests or troughs. It can be measured by any two consecutive points in a wave. Wavelength is commonly designated by the sign λ (lambda). Wavelength depends on the medium ( for example air, water or vacuum) that a wave travels through.

According to the following wave equation, it can also be deduced that wavelength is inversely proportional to frequency.

V = f λ

V is the speed

F is the frequency

λ is wavelength

C. Wavelength is the length of one complete wave cycle

Wavelength of a sine wave, λ, can be measured between any two points with the same phase, such as between crests, or troughs, or corresponding zero crossings as shown

HELP PLEASE!!!

irakobra [83]

Answer:

10kN

Explanation:

Given data

m1= 50kg

u1= 3m/s

m2= 100kg

u2= 6m/s

v1= 2m/s

time= 0.04s

let us find the final velocity of Bruce v1

from the conservation of linear momentum

m1u1+m2u2=m1v1+m2v2

substitute

50*3+100*6= 50*v1+100*2

150+600=50v1+200

750-200=50v1

550= 50v1

divide both sides by 50

v1= 550/50

v1=11 m/s

From

F= mΔv/t

for Bruce

F=50*(11-3)/0.04

F=50*8/0.04

F=400/0.04

F=10000

F=10kN

for Max

F=100*(6-2)/0.04

F=100*4/0.04

F=400/0.04

F=10000

F=10kN

Explain Newtons Laws

Vsevolod [243]

1) Newton first law of motion: state“If a body is at rest it reamain at rest and if it is in a motion it continu its motion unless a net external force acting on it”

This law also called law of inertia

2) Newton second law of motion: states that ‟acceleration to the force acting on the body and inversky proportional to the mass of the body”

3) Newton's third law of motion: It is not possible to exert a force abody with out the body exerting a forces in the opposite direction.

These forces are called action and reaction forces

hope it's helpful ❤❤❤❤❤❤

How do you think speed affects car and driver safety?

blondinia [14]

An increase in average speed of 1 km/h typi- cally results in a 3% higher risk of a crash involving injury, with a 4–5% increase for crashes that result in fatalities. — Speed also contributes to the severity of the impact when a collision does occur. Hope this helps!

The speed of light in a vacuum is approximately 0.3 gm/s. What is the speed of light in meters per second?

klemol [59]

We have to convert Gm/s to m/s.

As $1 \ Gm/s = 10^9 \ m/s$

Therefore the speed of light in vacuum,

$c = 0.3 \ Gm/s = 0.3 \times 10^9 \ m/s \\\\ c= 3 \times 10^8 \ m/s$

Thus, the speed of light in m/s is $3 \times 10^8 \ m/s$
