Answer:

v2=6400m/s

Explanation:

Consider the elastic head-on collision between a sledge hammer with 2000 g mass and a golf ball with a 5 g mass. The initial velocity of the sledge hammer is 16 m/s, and the golf ball is initially at rest. the concluding part of this question could be:

this is an elastic collision

we know from the principles of linear momentum that the total momentum before collision must be equal to total linear momentum after collision

momentum is the product of mass and its velocity

m1u1+m2u2=m1v1+m2v2

m1=2000g mass of the sledge hammer

u1=16m/s initial velocity of the sledge hammer

m2=5g mass of the golf ball

u2=0 velocity of the golf ball

v1=0m/s final velocity of the sledge hammer

v2=? final velocity of the golf ball

2000*16+5*0=2000*0+5v2

v2=2000*16/5

v2=400*16

v2=6400 m/s

Katen [24]

Answer:

A. 3,000,000 m

B. 0.25 km

C. 10 m

D. 1,000 cm

Explanation:

no hablo español, así que solo ingrese esto en el traductor de G*ogle

A. One kilometer equals 1000 meters, so

3,000*1,000 = 3,000,000 m

B. One meter equals 0.001 kilometer, so

250*0.001 = 0.25 km

C. One centimeter equals 0.01 meter

1,000*0.01 = 10 m

D. One milimeter equals 0.1 centimer, so

10,000*0.1 = 1,000

Anestetic [448]

The efficiency of a light source is the percentage of its energy input that gets radiated as visible light if some of the blue light in an led is used to cause a fluorescent material to glow the overall efficiency of the LED decreases.

How efficient is LED?

Different wavelengths that correlate to different visible colours are used in LED light therapy. Various shades pierce the skin at different rates.

  1. Your skin's outermost layer is impacted by blue light.
  2. Yellow light is more enveloping.
  3. Red light penetrates your skin more deeply.
  4. The deepest penetrating light is near-infrared.

Different LED hues have various effects. For instance, according to experts red LED light therapy has the potential to reduce inflammation and boost collagen formation, which declines with age and is crucial for maintaining youthful-looking skin.

Acne-causing bacteria may be destroyed by a blue LED light therapy (P. acnes).

Hence the answer is the overall efficiency of the LED decreases.
