A baseball player throws a baseball with a velocity of 13 m/s North it is caught by a second player seven seconds later how far

is the second player from the first player

The second player is 91 meters far from the first player.

Why?

First, let be the +y the North, so, to solve the problem we can use the following formula:

y=yo+v_o*t+\frac{1}{2}*a*t

Now, subsituting the given information, we have(assuming that the speed is constant):

\\\\y-yo=13\frac{m}{s}*7s+\frac{1}{2}*0*7s\\\\y-yo=91m\\\\distance=91m[/tex]

Hence, we have that the second player is 91m far from the first player.

Have a nice day!

Part b suppose the magnitude of the gravitational force between two spherical objects is 2000 n when they are 100 km apart. what
kobusy [5.1K]
<span>b) The force with a distance of 150 km is 889 N c) The force with a distance of 50 km is 8000 N This question looks like a mixture of a question and a critique of a previous answer. I'll attempt to address the original question. Since the radius of the spherical objects isn't mentioned anywhere, I will assume that the distance from the center of each spherical object is what's being given. The gravitational force between two masses is given as F = (G M1 M2)/r^2 where F = Force G = gravitational constant M1 = Mass 1 M2 = Mass 2 r = distance between center of masses for the two masses. So with a r value of 100 km, we have a force of 2000 Newtons. If we change the distance to 150 km, that increases the distance by a factor of 1.5 and since the force varies with the inverse square, we get the original force divided by 2.25. And 2000 / 2.25 = 888.88888.... when rounded to 3 digits gives us 889. Looking at what looks like an answer of 890 in the question is explainable as someone rounding incorrectly to 2 significant digits. If the distance is changed to 50 km from the original 100 km, then you have half the distance (50/100 = 0.5) and the squaring will give you a new divisor of 0.25, and 2000 / 0.25 = 8000. So the force increases to 8000 Newtons.</span>

Why do nuclear power plants use fission rather than fusion to generate
kicyunya [14]

B. Fusion requires very high pressure and temperature.

Explanation:

Nuclear fusion is the combination of atomic nuclei into larger ones with the release of a large amount of energy.

Nuclear fission is the decay process in which a heavy nuclide is bombarded with with neutrons.

  • Both processes release a huge amount of energy.
  • But fusion produces far more energy.
  • The reason why nuclear fusion is not in use is because of the high pressure and temperature needed start it.
  • The activation energy is high and the energy barrier is very great.
  • Only the core of the sun naturally favors fusion
