Answer:
B
Explanation:
Momentum is the product or multiplication of a body's mass and its speed.
Since all options have the mass and speed in the same units, there is no need for conversion.
A. 20 x 500 = 10000, B. 200 x 60 = 12000
The same goes for the rest!
Answer:
F' = 64 N
Explanation:
The force of gravitation between two objects is given by Newton's Law of Gravitation as follows:
______________ equation (1)
where,
F = Force = 16 N
G = universal gravitational constant
m₁ = mass of the first object
m₂ = mass of the second object
r = distance between objects
Now, the masses of each object are doubled and the distance between them is same:
m₁' = 2m₁
m₂' = 2m₂
r' = r
Hence, the new force will be:
using equation (1), we get:
F' = 4 F = 4(16 N)
<u>F' = 64 N</u>
This question is a critical question. as we all know, when energy is added to any state of water, the particles move faster. and when energy is taken away from any state of water, the particles reduce speed. same with the particles of air. when energy is added; they move faster. when energy is removed; they move slower. so the answer is they move faster
Answer:
176.9N
Explanation:
The following data were given
wire length,L=37cm=0.37m
linear density=18g/m
tube length,=192cm=1.92m,
speed of sound,v=343m/s
Since it is an open-closed tube, the second harmonic frequency is expressed as
The relationship between the tension, linear density and second harmonic frequency is expressed as
Answer:
Significant Others
Explanation:
The relationship between Solomon and his coach is termed Significant Others.
George Herbert Mead used the words "Significant Others" in sociology to imply the individuals (friends, colleagues, boss, tutors, coach, etc.) that are the most significant or important in the wellbeing of an individual or self development of that individual.
In other words, they are individuals who have an important influence or play a formative role in shaping the behaviour of another
