Answer:

0.12m/s

Explanation:

v=λf

Given that, λ = 12cm = 0.12m

T = 1second

(A period T is the time required for one complete cycle of vibration to pass a given point)

frequency 'f' is unknown but we can get frequency from f = 1/T = 1/1 = 1Hz

therefore, v= 0.12 × 1 = 0.12m/s

A horse has a momentum of 25 kg*m/s and a velocity of 2.5 m/s. What is the horse mass?
Ne4ueva [31]
<h3>Answer:  10 kg</h3>

==================================================

Work Shown:

We have these variables

  • p = momentum = 25 kg*m/s
  • m = mass = unknown
  • v = velocity = 2.5 meters per second

Solving for the mass gets us...

p = m*v

25 = m*2.5

25/2.5 = m

10 = m

m = 10

The mass of the horse is 10 kg.

lesantik [10]

Answer:

(3) Gabbro

Explanation:

Gabbro is a  dark-colored, coarse-grained and intrusive igneous rock. Generally, this type of rock is having dark green or black color. The main composition of this type of rock is augite and plagioclase minerals.

The approximate composition of Gabbro rock given as

1 .25% plagioclase feldspar  

2.5% amphibole

3.10% olivine

5460% pyroxene

Therefore the answer will be (3).
