Ball A has a mass of 50 kg. Ball B has a mass of 75 kg. Both move at the same velocity. Which has a greater momentum?
Answers
Answer:
Ball B
Explanation:
I say this because its the heavier one?
The momentum of a body increases with increase in mass. Hence, among the two balls, the ball with the greater mass that is ball B has the greater momentum.
What is momentum ?Momentum is the ability of a moving object to bring the force effective to make maximum displacement. It is the product of mass and velocity.
P = mv
Thus, as the velocity and mass increases, the momentum increases. The force applied on a body with greater mass makes greater acceleration and greater momentum.
Therefore, at constant velocity, the object with the greater mass will have the greater momentum. Then, the ball with 75 kg mass is having the greater momentum.

C. In Fraired background radiation is found all over the observable universe
D. Far away stars show a blueshift
Answers
Answer:
A. Far away stars show a red shift and B. Microwave background creation is found all over the observational universe
Explanation:
Red shift in color indicates that galaxies are moving away from Earth. This is proof that the Universe is continously expanding, which also supports the big bang theory.
The Big Bang theory predicts that the early universe was a very hot place and that as it expands, the gas within it cools. Thus the universe should be filled with radiation that is literally the remnant heat left over from the Big Bang, called the “cosmic microwave background".

A gold bar has a density of 19.3 g/mL. If the gold bar has a mass of 6.3 grams, what is the volume?
Answers
Answer:
The correct answer is "0.32 mL".
Explanation:
The given values are:
Density of gold bar,
d = 19.3 g/mL
Mass of gold bar,
m = 6.3 grams
Now,
The volume will be:
⇒ [tex]Density = \frac{Mass}{Volume}[/tex]
or,
⇒ [tex]Volume=\frac{Mass}{Density}[/tex]
On substituting the values, we get
⇒ [tex]=\frac{6.3 \ g}{19.3 \ g/mL}[/tex]
⇒ [tex]=0.32 \ mL[/tex]

The Pine Mountain Ski Jump in Michigan is an artificial ski jump and is one of the highest in the world. It is approximately 200 meters high. Calculate the mechanical energy of a 52-kg jumper if halfway down the ski jump, the jumper has both potential and kinetic energy. At this point, the jumper's speed is 28 m/s.
Answers
Answer:
71344 J
Explanation:
From the law of conservation of energy,
Mechanical Energy = Kinetic Energy + Potential Energy
M.E = (mv²/2)+ mgh.................... Equation 1
Where M.E = Mechanical Energy, m = mass, v = Velocity, h = height, g = acceleration due to gravity.
Given: m = 52 kg, v = 28 m/s, h = 100 m (half way down the ski jump)
Constant: g = 9.8 m/s²
Substitute these values into equation 1
M.E = (52×28²/2) + (52×100×9.8)
M.E = 20384+50960
M.E = 71344 J

Calculate the velocity of:
A bus travelling through town, with a mass of 5040 kg and kinetic energy of
493,900 J.
Answers
Answer:
solution
given,
mass(m)=5040kg
kinetic energy(ke)=493,900
velocity(v)=?
[tex]ke = \frac{1}{2} mv {}^{2} \\ 493900 = \frac{1}{2} \times 5040 \times v {}^{2} \\ 493900 = \frac{5040v {}^{2} }{2} \\ 493900 = 2520v {}^{2} \\ v {}^{2} = 196 \\ v = \sqrt{196} \\ v = 14ms {}^{ - 1} [/tex]
When an object moves from one point to other point, it possess the energy which is called the Kinetic energy of the object.
The velocity of he bus is 14 m/s.
Given that, a bus travelling through town, with a mass of 5040 kg and kinetic energy of 493,900 J.
So the kinetic energy expressed by the formula given below.
[tex]k=\dfrac {1} {2}mv^2[/tex]
Where, [tex]k[/tex] is the kinetic energy in joules, [tex]m[/tex] is the mass of object in kilograms and [tex]v[/tex] is the velocity of the object in meter per second.
So the velocity of the bus can be calculated by substituting the values in above formula.
[tex]493900=\dfrac{1}{2}\times5040\times v^2[/tex]
[tex]v^2=196\\\\v=\sqrt{196}\\v=14\;\rm m/s[/tex]
The velocity of he bus is 14 m/s.
