Imaging playing a game of baseball on the moon, which has less gravity than Earth and no atmosphere. How would you want to change the game to make it play fairly and fun?
Answer:
In order to reduce the mass of the bat and raise the mass of the ball, the transfer of momentum could only be extended to a distance equal to the size of a baseball stadium. Although the ball's acceleration stays constant regardless of its mass (provided that the mass is less than the mass of the moon), your running time around the bases will be reduced as a result of the increased mass of the ball.

Answer:
How is hydrogen obtained and separated from other nearby substances?
photoelectrolysis, a photoelectrochemical cell submerged in water uses sunlight to separate the water into hydrogen and oxygen bubbles. In the thermochemical cycle, water is heated to 800 to 1,000 °C, with the molecule. splitting to release hydrogen. The main drawback of this method is that it requires nuclear power
How is Hydrogen used?
Hydrogen can be used in fuel cells to generate electricity, or power and heat. Today, hydrogen is most commonly used in petroleum refining and fertilizer production, while transportation and utilities are emerging markets
What products are made from Hydrogen?
Hydrogen is a very useful element. It is used to make ammonia for fertilizers, refining metals, and methanol for making artificial material like plastics. Hydrogen is also used as a rocket fuel where liquid hydrogen is combined with liquid oxygen to produce a powerful explosion.
Any environmental concerns about the use of Hydrogen?
Emissions of hydrogen lead to increased burdens of methane and ozone and hence to an increase in global warming. Therefore, hydrogen can be considered as an indirect greenhouse gas with the potential to increase global warming.

Describe at least two ways to determine whether a relationship is proportional.
If two different quantities are given, how to check whether the relationship between them is proportional ? We have to get ratio of the two quantities for all the given values. If all the ratios are equal, then the relationship is proportional. If all the ratios are not equal, then the relationship is not proportional.
Why would a train need more than one locomotive? Apply forces and net forces to explain what problems might be solved by adding locomotives to a train.
The more the number of locomotives in the train the greater the net force supplied to move the train forward.
A train is used for transportation on land. A train consists of a locomotive engine which provides the forward force which the train requires to move from place to place.
The more locomotives, the more power is provided to pull the train forward thereby providing a greater net force that moves the train in the forward direction.

How much of the rope must be pulled in if a force of
648 N is needed to lift a 150 kg desk 2.46 m?
(Disregard friction.)
Answer:
work done on desk = m g h = 105 * 9.81 * 2.46 = 2534 Joules
Explanation:
so work in = 2534 / 0.875 = 2896 Joules
that is your 648 times distance your hand moved holding the rope
2896 = 648 * x
4.47 meters
I think maybe a typo, 648 N is too big, maybe 64.8 ? Any block and tackle system does better than that.
Obtain Center of Mass:
Obtain the center of mass of an axis of a thin wire with a curve defined by [tex]y=f(x)=x^{3/2}[/tex] from x=0 to x=1 and a lineal density of mass of [tex]p(x)=x^{2}[/tex]
Hi there!
To find the center of mass:
[tex]com = \frac{1}{m}\int\ {rdm}[/tex]
We can begin by changing "dm" into an available quantity by expressing the lineal density as a function:
[tex]\lambda = x^2 = \frac{m}{x}\\\\x^2 = \frac{m}{x}\\\\x^3 = m \\\\[/tex]
Differentiate both sides:
[tex]3x^2dx = dm[/tex]
Let:
[tex]r = f(x) = x^{3/2}[/tex]
Thus:
[tex]com = \frac{1}{m} \int x^{3/2}3x^2dx\\\\com = \frac{1}{m} \int }3x^{7/2}dx\\[/tex]
Evaluate:
[tex]com = \frac{1}{m} \frac{2}{3}x^{9/2}\left \| {{1 \atop {0}} \right.[/tex]
We found 'm' above, so plug the expression in:
[tex]com = \frac{1}{x^3} \frac{2}{3}x^{9/2}\left \| {{1 \atop {0}} \right. \\\\com = \frac{1}{x^3} \frac{2}{3}x^{9/2}\left \| {{1 \atop {0}} \right. \\\\com = \frac{2}{3}x^{3/2}\left \| {{1 \atop {0}} \right. = \boxed{\frac{2}{3}}[/tex]

a car has a displacement of 480 kilometers to the east in 8 hours . What it’s the velocity per hour?
Answer:
The velocity is 60 km/hr.
Explanation:
Given:Displacement (d) = 480 km = 48000 m
Time (t) = 8 Hours = 480 minute
Velocity (v) = ?
Now,
Velocity = Displacement ÷ Time
v = d/t
v = 480/8
v = 60 km/hr
Thus, The velocity is 60 km/hr.

Hello, I wanted an answer from a mathematician. The number 1.04 is closer to the number 1, 2, 1.25 or 1.5.
Answer:
1
Explanation:
line them up in order.
1, 1.04, 1.25, 1.5, 2
1.04 is in the middle of 1 and 1.25
1.04-1=0.04
1.25-1.04= 0.21
Answer:
1
Explanation:
1.04 lies between 1 and 1.25.
1.04 is 0.21 away from 1.25
1.04 is 0.04 away from 1.
0.04<0.21
One mole (6.02×10^23 atoms) of helium atoms in the gas phase has 3700 J of microscopic kinetic energy at room temperature. Assume that all atoms move with the same speed. The mass of a helium atom is 6.68×10^−27 kg. What is the speed of a helium atom?
This question involves the concepts of kinetic energy, and rms speed.
The rms speed of helium atom at 5800 K is "1.05 x 10¹⁵ m/s".
We will use the formula of the average kinetic energy of gas molecules to find out the rms speed of the hydrogen atom. rms speed is the root mean square speed of an atom:
[tex]K.E =\frac{1}{2}mv^2\\\\v=\sqrt{\frac{2K.E}{m}}[/tex]
where,
v =rms speed = ?
K.E = Kinetic Energy of Helium atoms = 3700 J
m = mass of hydrogen atom = 6.68 x 10⁻²⁷ kg
Therefore,
[tex]v=\sqrt{\frac{2(3700 J)}{6.68\ x\ 10^{-27}\ kg}}\\[/tex]
v = 1.05 x 10¹⁵ m/s

imagine that the Earth's rotation slowed down to one half of its original speed. What would life be like? Write a response that describes how your life would change. As always, write in complete sentences!
Explanation:
if you meant ¾ of it's original speed then a day would have 42 hours thus making days & nights longer. Our weight would be more, because as the Earth would rotate slower, it would exert less centrifugal force on us. There would also be a temperature change as each hemisphere (Eastern and Western) would get more time to warm up from the Sun's rays. the year would obviously have half the amount of days and week which would mess up our schedules as well as our holidays and lastly there'll be younger deaths.

A spring of spring constant k=500 N/m is elongated from its initial length by a distance x=2 cm, then the force applied by the spring is:
A. F= 3N.
B. F= 10 N.
C. F=500 N.
D. F= 0N.
Answer:
1.96 kg * m2/s2
Explanation:
I'm assuming that you are asking what is the elastic potential energy stored in the spring at the position stretched by 16.5 cm...
Since you know the spring constant k, 144 N/m and the spring stretch from the equilibrium position x, is 16.5 cm, or 0.165, you find the spring's potential energy from the equation PE = 12kx2, which equals 1.96 Joules, or kg * m2/s2 if you want SI units.
The total momentum of a system of two moving identical bodies is zero. What should be true about the velocities of the bodies?
A) The velocities should be equal in direction and opposite in magnitude.
B) Both velocities should be zero
C) Both velocities should be equal in magnitude and opposite in direction
D) the velocities should be equal in magnitude and opposite in direction
For a zero total momentum of two bodies, the two velocities of the two bodies should be equal in magnitude and opposite in direction
According to the principle of conservation of linear momentum, the total momentum of an isolated system is constant.
[tex]Pi = P_f \\\\m_1u_1 + m_2u_2 = m_1v_1 + m_2 v_2[/tex]
where;
u is the initial velocity of the two bodiesv is the final velocity of the two bodiesm is the mass of the two bodiesWhen the total momentum is zero, the velocities of the two bodies will have equal values but opposite signs.
Thus, we can conclude that for a zero total momentum of the two bodies, the two velocities should be equal in magnitude and opposite in direction
